Description

An Internet protocol interactive television system and its realization method

technical field

The present invention relates to a technology of interactive video/audio data transmission and simultaneous charging on the Internet, in particular to an IP (Internet Protocol) interactive TV system and its realization method.

Background technique

At present, with the rapid development of information technology and the increasing popularity of the Internet (Internet), various multimedia information has gradually penetrated into people's daily life. For example, people can watch various audio and video information through TV, and people can also use Internet By ordering the multimedia information they are interested in on the Internet, etc., people can obtain very useful information for themselves through these information technology means. However, these traditional means of information acquisition are increasingly unable to meet people's increasingly diverse needs. They cannot realize the interaction between the audience and the broadcast center, and cannot closely connect the audience's information with the broadcast center.

For traditional TV, he sends the recorded programs to receiving terminals distributed in various places through a TV broadcasting center. After receiving the information, the receiving terminal undergoes a series of processing to restore and display the audio and video information. out, users can only receive and watch passively, and the only option is to watch TV programs produced by different TV distribution centers. The audience is completely limited to passive acceptance.

Due to the continuous development of network technology, there are still some ways to obtain information through users' on-demand broadcasting on the Internet, which expands the range of choices to a certain extent, but in the final analysis, this method still passes through one or a group of servers. Sending audio and video information also belongs to the one-way communication information between Internet users and servers. Users cannot share their own wishes or information with others, and some of them are only a few users authorized by the system. This is advocating individuality, Today's advocacy of freedom undoubtedly has its huge limitations. In the above-mentioned prior art, the interaction between the information provider and the audience is limited, and the two cannot communicate face-to-face and two-way directly through the existing audio/video technology.

In addition, the general video conferencing system adopts the client/server mode, and the video/audio signals of all parties in the conference are transmitted between the host's server and the participants' clients. However, in this mode, when there are too many meeting participants, the server will be overloaded soon, causing network congestion, severe delays in image and sound transmission, and even system crashes. It is not suitable for applications with a large number of people. However, if the number of servers is to be increased to share data traffic, the cost will rise rapidly, and the increased system capacity is also limited.

Contents of the invention

Therefore, the object of the present invention is to provide a kind of IP interactive TV system and method, it is a kind of realization method or system of the information interaction of viewer and broadcasting center, adopts large-capacity, low-cost interactive data transmission mode, through it, It allows every user to equally and openly participate in sending or receiving information, providing services or receiving services on the Internet, not only allows me to see the world, but also allows the world to see me, and can accommodate large-flow data transmission, almost System performance will not be affected by the increase in the number of users. In addition, through this system, it is also possible to conveniently charge and pay for the flow of such information.

The present invention provides an IP interactive TV system, including: a main control server, used to manage and control the entire IP interactive TV system, and a distribution forwarding server; forwarding audio and video data streams; user terminals, including a host user terminal, used to transmit audio and video data streams to the forwarding server; and audience user terminals, used to receive the TV host terminal through the forwarding server provided audio and video data streams, and interacts with the TV presenter terminal in an interactive manner.

Detailed ways

Considering the current status of the application and development of information technology, more and more users are surfing the Internet through broadband, and the data transmission rate of user terminals tends to increase. The present invention proposes a method and system for realizing IP interactive TV on the Internet. In this system, for any user distributed on the Internet, you can:

●Openly create your own interactive TV center;

●Open access to iTVCentral programs created by other users;

The system can also carry out open interactive information billing for users who create and participate in interactive TV, realize the transfer of fees, and then use this system to identify the user's wealth index on the Internet, or value index, and personal online business index.

In the interrelationship among the three, the user establishes an IP interactive TV center and other viewers who participate in the IP interactive TV, as shown in 1 in Fig. 3A, and at the same time, the interactive TV anchor and the interactive billing device are connected , as shown by 2 in Figure 3A, and in addition, the interactive TV viewer is in contact with the interactive billing device, as shown by 3 in Figure 3A. Through these links, the interactive relationship among the three is produced, as shown in Figure 3A 4 (see Figure 3B and C for details). This is the heart of interactive television. Through it, the three are mutually interactively linked: any user can create an iTV, and any user can also participate in an iTV, and then, through the interactive billing device, the iTV host can also receive information from any user who participates in its iTV. Information fees are received at the viewer. For a detailed description of 4 in FIG. 3A (see FIGS. 3B and C for details), refer to FIG. 3B.

In this way, through this system, ordinary users or IP interactive TV viewers can freely share information with the IP interactive TV center (host). The information is sent to the presenters participating in this IP interactive TV center, which fully reflects the world can see my unique personality. At the same time, through the open interactive information billing and payment, it reflects the growth of the user's wealth and value index on the Internet, as well as the identification and growth of the personal online business index.

The following is a detailed description of the system.

Fig. 1 illustrates the frame structure of the IP interactive TV system of the present invention. In this IP interactive TV system, it is aimed at the majority of Internet users, which can be general dial-up Internet users, or users who access the Internet through a proxy server. The user logs in through the Internet, communicates with the main control server of the system, and then the system transfers the user to other servers through scheduling and according to the user's specific control instructions, and continues to provide the service required by the user, which reduces system load.

The core of this system is the interactive relationship between the interactive TV host, participants (viewers), and the interactive billing device. That is, any user can create an interactive TV, and any user can also participate in the interactive TV. Then, through interactive Billing device, iTV hosts are also able to receive information fees from any viewers who participate in their iTV. See Figure 3B for details.

The moderator user terminal includes a video/audio signal collection device, such as a video camera, used to collect the moderator's audio/video signal in real time to form an audio/video data stream, which is provided externally and can be charged; the audience user terminal also It includes a video/audio signal collection device, which is used to collect the audience's audio/video signal to form an audio/video data stream for communicating with the host.

In order to realize the interactive relationship among the three, at first two interactive devices are installed on the main control server group: an interactive environment device and an interactive charging device.

The interactive environment device is for the user and the main control server, that is, after the user logs into the system on the Internet, the main control server group can receive the user's control command, and after the main control server group receives the user's command, the system passes the internal Scheduling, find out the information related to the user's control command, and return it to the user, and record the relevant information into the database, so as to establish an interactive environment for the user on the server.

For interactive environment installations, including creating iTV installations for openly creating IP iTV center programming; joining iTV installations for openly joining IP iTV center programming; and video imaging installations for handling the transmission of video images .

The so-called open creation of IP interactive TV center programs by users means that for any user on the Internet, as long as he logs into the system, he can create his own IP interactive TV center programs arbitrarily without any restrictions. Refer to FIG. 3A for its specific position in the system. In addition, refer to FIG. 4 and FIG. 5 for its detailed flow of creating an interactive TV.

Openly joining IP interactive TV center programs for users means that for any user on the Internet, as long as he logs into this system, he can freely participate in his favorite IP interactive TV center programs without any restrictions. Of course, generally speaking, the user will make a decision based on the wealth index of the IP interactive TV host on the Internet, because in this way, the user can benefit from the growth of his own personal wealth or value on the Internet. Refer to FIG. 3A for the specific location in the system where the user openly joins the program of the IP interactive TV center. In addition, refer to FIG. 6 for the detailed flow of participating in the interactive TV program.

At the same time, for users to openly join IP interactive TV center programs, it also involves an IP interactive TV query/collection process. After the user collects, there is a matching device for the collection in the background of the system, so that the user can obtain information about the collection after the next login. More optimized information for this collection. Details about this process are described in Figure 7.

In addition, in the interactive environment device, there is also an interactive image device, which provides a high-efficiency high-definition application method and system for narrow-band video applications. Through it, users can also obtain video images, which are in the video transmission During the process, the system captures an image from the transmitted video image at regular intervals to provide to the user who needs to save the image. After obtaining these images, the user can use this system to participate in interactive TV programs. Browse during or after exiting the program. For its specific implementation details, refer to FIG. 7B.

As for the interactive billing device, after the system performs information flow on the Internet according to the user, the information fee generated due to the flow of the information information is openly timed and billed by the system. Through this device, you can Distributed users distributed on the Internet pay. Refer to FIG. 3A and FIG. 9A for a detailed description of the location and flow of the device in the system.

Because there is a billing and payment device in the system, IP personal account identification device, IP personal wealth index (or value index) device and network business index device are thus derived.

For the IP personal account account identification device, it is a marking method (judging by different colors) used to identify the approximate fund balance on the user's current personal account. The specific implementation details are shown in Fig. 9B.

For the wealth index device, users can judge an individual's personal wealth index on the Internet through it, and based on this, they can choose who to exchange and share information with, so as to realize their own wealth (or value) on the Internet growth of. See Figures 10 and 11 for a more detailed description of the wealth (value) index device.

For the online business index device, it is the index of personal wealth index/cumulative time, and through the IP interactive TV network business index, it shows the user's activity level on the Internet more accurately. Its detailed description is shown in Fig. 11B.

Figure 2 illustrates the topology of the IP interactive television system of the present invention. In order to realize the interactive relationship formed between the interactive TV host, the participants (viewers), and the interactive billing device (the interactive relationship shown in 4 in Figure 3A, see Figure 3B and C for details about 4), that is, any user Interactive TV can be created, any user can participate in the interactive TV, and then, through the interactive billing device, the interactive TV host can also receive the information fee from any viewer who participates in his interactive TV. At the same time, considering the system load and other issues, the system will adopt the following topology. In this topology, there are mainly three process relationships: the distributed user group process on the Internet, the master server group process, and the distributed forwarding server group process on the Internet. In the forwarding server group, There are also forwarding server group convening end and sending end.

In the system topology structure of the present invention, the distributed user group located on the Internet establishes a data flow process relationship with the main control server group through registration and login, and exchanges information between them through the C/S mode.

The forwarding server group is also registered and logged in first, and its relevant information is recorded in the database of the main control server. According to the registration information of the forwarding server, the main control server group is internally scheduled and controlled, and the forwarding server group (including the calling end and the sending end) The establishment of data flow relationship and two-way communication also adopts the C/S mode.

Due to the control and participation of the master server group, the distributed user group located on the Internet and the forwarding server group also located on the Internet establish a logical control relationship and a bidirectional flow of data flow to realize communication.

Looking at the system architecture and topology of the present invention, the master control server group serves as a link between the distributed user groups on the Internet and the forwarding server groups also distributed on the Internet. Through him, users distributed on the Internet can communicate with the forwarding server group in turn, and then through the forwarding server group, the user's information is forwarded to another or another group of distributed users on the Internet.

In this way, the application of the IP interactive television system of the present invention on the distributed Internet is solved from the perspective of system architecture and system topology. The IP interactive TV system is just used to solve the problem of how to make the multimedia application on the Internet centered on me and let the world see me and hear my information in today's widely used Internet. Through this system architecture and system topology, distributed users on the Internet can establish connections efficiently and quickly, while the load on the entire system is small. Once users establish connections, the master server is basically in an idle state. Waiting for requests from other users; users who have already established a connection turn to forwarding information to them through the forwarding server. At the same time, inside the main control server, there is also a billing and payment device, through which billing and transfer of information is carried out, which realizes the growth of the user's wealth and value on the Internet and the growth of the personal Internet business index.

In this way, through the topological structure of the system, distributed users can create interactive TV and distributed users can participate in interactive TV from the system framework. In addition, through the scheduling and control of the main control server, the information flow between the two can be controlled. Billing and payment, thus forming an interactive relationship among the three (4 in FIG. 3A, that is, as shown in FIG. 3B and C).

In this system, its topological structure and overall architecture are a combination of peer-to-peer structure and traditional C/S structure, which is different from traditional C/S structure, and is a combination of traditional C/S structure. Expand and extend. In this way, from the perspective of system stability, it is undoubtedly able to stand the test, and it also has better system scalability, and the system efficiency is greatly improved.

Figure 3A illustrates the overall flow of the system. Through the process description of IP interactive TV, we can understand more specifically a method of realizing the overall system architecture and system topology shown in Figure 1 and Figure 2, and at the same time understand the process and some details of system implementation in more detail.

In the system of the present invention, for users distributed on the Internet, in order to realize the interactive relationship formed between the interactive TV host, the participants (viewers), and the interactive charging device (the interactive relationship shown in 4 in Fig. 3A , see Figure 3B and C for a more detailed description of 4), the user must first run the client software of the system to perform user registration, login, identity verification, etc.

Specifically, the user must first register the user's basic personal information on the main control server of the system, including:

● Name:

● Gender:

● Age:

● Province:

● Address:

● Login password:

● Email address:

● Remarks:

After the user fills in these personal basic information, he sends the registration information to the main control server. When the main control server receives the new user registration, it inserts a record in the customer basic information table (userbaseinfo) of the main control server database to record the user's information. Basic information, and assign a system-unique ID number to the user, that is, the user ID number, and then return to the user and the information that the user has successfully registered. The user needs to record the ID identification number assigned by the master server and the login password, etc. information for the user to use when logging in.

Once the user registration is successful, the user can log into the system, which is to submit the user login command to the main control server with the ID number returned to the user by the main control server when the user registration is successful and the login password set by the user himself. , after the main control server receives the user's request to log into the system, it will start to authenticate the user, that is, use the login ID number and login password provided by the user to check whether there is a match in the basic user data table of the database. If there is a record, the user identity verification is passed, and the system will return the login success information to the user. On the contrary, if there is no matching record, it means that the user has not registered in the system, or provided a wrong user ID and The password pair is used to log in. At this time, the system returns a login failure message to the user, and the user has to register or provide the correct user ID number and login password pair to log in again;

Since it is necessary to provide information forwarding services to user groups distributed on the Internet, after the user logs in successfully, the system not only records the ID number of the user logged in, but also the IP address to be used for socket communication. The socket command port number, audio port number, video port number, etc. are registered, and recorded in the normal user login information table (normalloginfo) of the system master server database. Wherein, user ID number, IP address, command port number and other information can be obtained when the user logs in. At this time, the information is recorded in the common user login information table (insert a new record), and the master server returns the login information to the user. At the same time as the success message, the user's IP address and command port number are returned to the user, and the user records it locally; The ID number is a distinguishing mark. After the main control server receives it, it updates the common user login information record table according to the user's ID number and returns it to the user. Similarly, the user records his own audio and video port information locally for future use. .

Similarly, for the login registration of the forwarding server, its processing method and method are the same as those of ordinary users, except that the login information of the forwarding server is recorded in the special user login information record table (specialloginfo).

Considering the large increase of broadband users at present, one of the processing methods of this system is to use the resources of these broadband users distributed on the Internet to bind the client and the forwarding server together. Among ordinary users who log into the system, the client Determine whether it is a broadband user, if it is a broadband user, register the special user with the main control server (insert another record in the specialloginfo table), so that the user can use the service provided by the system while the system uses its broadband Bandwidth, use it as a forwarding server to provide information forwarding services for other users in the background.

This forwarding service mode is a better method for solving the cost of the forwarding server proposed in order to meet the framework and structure of the system of the present invention. This method of storing food for the people greatly reduces the hardware cost of the system of the present invention. Expenditure, what he asks for, is just to provide several PCs as master servers to form a master server group to control and coordinate the logical relationship between ordinary users and forwarding servers as well as the data flow on the Internet. Successful forwarding of the service and its dispatch.

When a user terminal successfully logs into the system and successfully registers its own information on the main control server (that is, completes the identification process of the user's identity in this system), it can submit to the main control server to create its own interactive TV center, or participate in Someone else's IP interactive TV center.

If a user wants to create his own IP interactive TV center, that is how the system handles users distributed on the Internet to openly and arbitrarily create an IP interactive TV center program (shown in Fig. The information (sound and image, etc.) is transmitted to other Internet users who participate in the IP interactive TV center, and then they can submit the control command to create an interactive TV center to the main control server. The user only needs to provide the following information to the main control server:

● Name of iTV Center:

● Password for other users to participate in iTV (if necessary):

● The price per unit time that other users need to pay when participating in the IP interactive TV (if necessary):

After receiving the control command submitted by the user, the main control server uses the background scheduling and control of the system center server group. Specifically, it searches the special user login information record table (specialloginfo) for idle information that has not been used by the system. Resource----forwarding server, if the system finds that the system still has free forwarding server resources, the master server will communicate with the forwarding server through the command port, asking it to provide forwarding services for the user, when the forwarding server receives the information, Allocate resources for the user, such as building audio and video sockets, initializing the sending target queue of the forwarding server, etc., and filling the sending target queue according to the sending information target sent by the master server, so that once a user sends information to The forwarding server, the forwarding server forwards the information to the corresponding destination in turn according to the sending target queue.

The forwarding server allocated by the main control server may be a one-level structure, that is, only one level of forwarding server is allocated between the moderator user terminal and the audience user terminal, that is, the moderator user terminal itself is equivalent to the convening terminal , the forwarding server acts as the sending forwarding server. The forwarding server can also have a two-level or multi-level structure. In this application, only the two-stage forwarding server (convening end and sending end) is taken as an example to illustrate the present invention.

When initializing the forwarding server queue, for the calling end of the forwarding server, the information of the transmitting end of the forwarding server and the information of the founder (host) of the IP interactive TV center need to be added to the sending target queue, and these information include:

● The ID number of the moderator (or the sender of the forwarding server):

● IP address of host (or forwarding server sender):

● The command port number of the moderator (or forwarding server sender):

● Audio (forwarding) port number of the moderator (or forwarding server sender):

● The video (forwarding) port number of the host (or the sending end of the forwarding server):

Among them, the ID number is used as the primary key of the information.

For the sending end of the forwarding server, once a user wants to join the IP interactive TV center, the master control server communicates with the sending end, and adds the user's information to the sending target queue of the sending end of the forwarding server. These information also include:

● Audience ID number:

● Viewer's IP address:

● Viewer's command port number:

● Viewer’s audio port number:

● Viewer’s video port number:

Likewise, the ID number is used as the primary key of the information.

When all these initialization information are processed, the master server will record the corresponding information in the tables of the database, these tables include:

● IP Interactive TV Center Information Form (meetinginfo):

● IP interactive TV center count information table (meetcountinfo):

Wherein the IP interactive TV center information (meetinginfo) table is mainly used to record the data of the user who created the interactive TV center and the data of the forwarding server information, and its main information includes:

● The ID number of the interactive TV creation user:

● Name of iTV creating user:

● The IP address of the interactive TV creation user:

● Name of IP Interactive Television Center:

● Password for other users to participate in this iTV center (if necessary):

● The price per unit time for participating in the Interactive TV Center:

● The IP address of the forwarding server (convening end):

● The command port of the forwarding server (convening end):

● The audio forwarding port of the forwarding server (convening end):

● The video forwarding port of the forwarding server (convening end):

● The IP address of the forwarding server (sending end):

● The command port of the forwarding server (sending end):

● The audio forwarding port of the forwarding server (sending end):

● Video forwarding port of the forwarding server (sending end):

As for the IP interactive TV center counting information (meetcountinfo) table, it is mainly used to load balance the forwarding server (transmitter), because if there are many other users participating in the interactive TV center created by the user, one forwarding server The server (sending end) cannot satisfy its forwarding service. At this time, it is necessary to consider adding a forwarding server (sending end), and the system has to record and analyze the information so that the system can team up the forwarding server with the main control server to carry out the load. Balanced scheduling and control enables the system to make better use of resources. Information recorded in the meetcountinfo table includes:

● The name of the IP interactive TV center (the system uses this name as an identification):

● The IP address of the sending end of the forwarding server:

● The command control port number of the sending end of the forwarding server:

● The audio forwarding port number of the sending end of the forwarding server:

● The video forwarding port number of the sending end of the forwarding server:

● The number of users who have joined the sender:

Its specific information is shown in Fig. 11 - the information database (meetinginfo) table of the interactive TV center.

When all these information are successfully recorded in the database of the main control server group and after processing the sending target information queue of the forwarding server, the main control server returns to the user the information that the IP interactive TV is successfully created. The user returns the IP address of the forwarding server (holding end), command port number, audio port number, video port number, and the IP address of the forwarding server (sending end), command port number, audio frequency port number, video port number and other information, After receiving these information, the user records them locally. At this time, the user can break away from the connection with the master control server, and send his audio information, video information and control commands to the forwarding server (holding end), and then The audio information and video information are sent to the forwarding server (sending end) through the forwarding server (sending end), and then the audio information and video information are sent to the users participating in the IP interactive TV through the forwarding server (sending end). In this way, the It realizes the forwarding and transmission of information between IP interactive TV creators (hosts) and IP interactive TV participants.

If the master control server cannot find enough resources in the specialloginfo table to create the IP interactive TV center for the user, the master control server returns to the user the information that the creation of the IP interactive TV center failed, and the reason for the failure (insufficient system resources). The user can submit the control command or control commands again.

In this way, the process for the moderator user to create the IP interactive TV center is over, and then, the founder (host) of the IP interactive TV center can send audio and video information to the users participating in the IP interactive TV through the hosting terminal of the forwarding server. The detailed process of creating an open IP interactive TV center by a user is shown in Fig. 4 and Fig. 5 and shown in Fig. 3A.

For IP TV viewers, he also has to go through processes such as system registration, login and system identification of users.

After he successfully logs in, he can view the IP interactive TV name, and he can choose one to join, and he can also save some IP interactive TV programs into his favorites. In this way, when the user logs in again, the master control server will actively send these The user sends the latest detailed information of the IP interactive TV. All of these are automatically completed in the background of the main control server according to different control commands of different users, and then the relevant information is recorded in the relevant database. When the user logs in next time, sent to this user.

When a user submits to the main control server a control command to participate in IP interactive TV (that is, to become a viewer of IP interactive TV), that is how the system handles users distributed on the Internet to openly join the IP interactive TV center program (see Figure 3A As shown in Fig. 6 and Fig. 7), he will submit the name of the IP interactive TV to be participated in to the main control server. After the main control server receives such a control command from the user, the main control server will schedule And control, according to the name provided by the user, look up the information of the corresponding forwarding server hosting end and sending end in the IP interactive TV information table (meetinginfo). IP address, command control port, audio information port, video control port and other information, and then the main control server communicates with the sending end, and adds the information of the user participating in the IP interactive TV to the sending target queue of the sending end of the forwarding server. The information includes: the participant's ID number, IP address, command control port number, audio information port number, video information port number, etc., wherein the user's ID number is also used as the primary key. In this way, the sender will forward the received information to the node identified by the IP address and port, that is, to the user.

After successfully completing the communication with the sending end of the forwarding server, the main control server records relevant information in the database, specifically, inserts a new record in the IP interactive TV participant information table (attendinfo), and the recorded information includes:

● The ID number of the creator (host) of IP interactive TV:

● IP interactive TV name:

● Participating user ID number:

● Participating users' IP addresses:

● Command port number:

● Audio port number:

● Video port number and other information:

Then update the sending user count at the sending end of the forwarding server in the counting table (meetcountinfo).

After the master control server updates the relevant records in the database, the master control server will return relevant information to the user, which includes:

● IP address of host of IP Interactive TV Center:

● The command port number of the host of the IP interactive TV center:

● The audio port number of the host of the IP interactive TV center:

● The video port number of the host of the IP interactive TV center:

● The IP address of the hosting end of the forwarding server:

● The command port number of the calling terminal of the forwarding server:

● The audio forwarding port number of the calling end of the forwarding server:

● The video forwarding port number of the calling end of the forwarding server:

● The IP address of the sending end of the forwarding server:

● The command port number of the sending end of the forwarding server:

● The audio forwarding port number of the sending end of the forwarding server:

● The video forwarding port number of the sending end of the forwarding server:

After the user receives the information, the user records the information locally. At this time, the user has successfully participated in the IP interactive TV, and can also receive the information data sent by the creator (host) of the IP interactive TV. See Figure 6 and Figure 7 for the detailed flow of the user's open participation in the program of the IP interactive TV center.

Similarly, if the user participating in the interactive TV program wants to quit the interactive TV program, he will also send a control command to the main control server. Just delete it from the target queue. It also disconnects the connection and flow of the data flow between the sending end of the forwarding server and the user.

In addition, for the creator (host) of IP interactive TV, once he wants to end the interactive TV, after sending relevant command information to the main control server, the main control server will notify the relevant forwarding server, and the forwarding server (including the hosting terminal) and sender) just clears the sending target queue list, releases relevant resources and reports its own state (idle) to the master control server, so that the master control server can redistribute and schedule the forwarding server according to the situation.

Through the above operations and processing, the IP interactive TV creator, that is, the connection between the IP interactive TV host terminal and the IP interactive TV viewer terminal has been successfully established (that is, the relationship of 1 shown in Figure 3A has been realized), which can Realize the flow and sharing of information between them.

For the logical relationship of 1 shown in Figure 3A, that is, any user distributed on the Internet can create their own interactive TV center without restriction; on the other hand, any user distributed on the Internet can join their own without restriction Interested in Interactive Television Center programming. However, without interactive billing and payment devices, the flow of information between them cannot form an individual's interactive wealth (or value) index.

Therefore, for the system of the present invention, there is another important aspect, that is how the system automatically handles the billing and payment of the IP interactive tariff (shown in FIG. 3A and described in FIG. 9A). Through it, it is possible to realize the flow record and transfer of tariffs generated by the flow of interactive information between IP interactive TV hosts and IP interactive TV viewers. Also through him, users realize their own wealth and value growth on the Internet, which is identified and reflected through the wealth index device. Please refer to Figure 10 and Figure 11 for a detailed description of the wealth index device.

The billing of the interactive tariff of this system is realized by installing an interactive billing device on the main control server. Specifically, the founder (host) of the IP interactive TV center is the party who pays the fee, and the audience who participates in the IP interactive TV is the party who pays the fee. When the IP interactive TV host creates the interactive TV, he specifies the unit time payment price for other users to participate in the IP interactive TV, and records it in the IP interactive TV center information table (meetinginfo) of the main control server database. When other users participate in the interactive TV program, the information recorded by the main control server in the transaction record table (bargaininfo) includes:

● The ID number of the billing party:

● The ID number of the payer:

● Paid price per unit time:

● Payment start time:

● Payment end time:

● Billing and payment sign:

Wherein, the payment start time is counted from when the user joins the IP interactive TV center, and the payment end time is from the time when the user leaves the IP interactive TV center, and the time difference is the time period for payment.

As another important part of this system, there is a scanning program running in the background of the main control server, which scans the database transaction record table (bargaininfo) circularly. Once a certain record in the table is complete (according to the charging sign Judgment), calculate and process this record in the main control server, and transfer funds from the IP personal account to complete the IP interactive TV creator (host) and IP interactive TV viewer (participant) flow of funds between them. The detailed flow of the billing and payment device is shown in FIG. 9A.

Like this, through the interactive billing/paying device, the connection between the host of the interactive TV program and the device (like the relationship of 2 in Figure 3A) is formed. In this relationship, the host should charge for providing information. The tariff can be recorded through this billing device;

On the other hand, the interactive TV viewer also forms a relationship with the billing device (like the relationship of 3 in Figure 3A), at this time, the information fee that the user should pay for participating in the interactive TV is also recorded.

Then, through 1, 2 and 3, the system forms an interactive relationship of 4 (for 4, see Figure 3B and C for details), that is, any user can create an interactive TV, and any user can also participate in an interactive TV. Then, through the interactive computer iTV hosts are also able to receive information fees from any viewers who participate in their iTV.

Among them, 1, 2, and 3 are indispensable. If any one of them is missing, the interactive relationship of 4 cannot be formed.

Using this IP interactive TV system, through a series of information forwarding and database operations, the interaction of information between the host of the interactive TV center and the viewers of the interactive TV is completed, as well as the distributed information transactions on the Internet. flow of funds between them. At the same time, it also completes the growth and flow of personal wealth and value on the Internet.

In order to better reflect the growth of users' personal wealth and value on the Internet, this IP interactive TV system also involves an IP interactive index (or called IP personal value index) device and a personal network business index device. It is mainly used to record the user's interaction index (value index) and online business index on the Internet. Through them, users can judge their activity on the Internet. In other words, users can know their wealth and value on the Internet. , which completely ignores all undeterminable factors on the Internet such as the user's name, gender, age, and unverifiable information in personal registration.

For a detailed description of the device, see Figure 10 and Figure 11;

The following is a detailed description of the system framework adopted by this system to realize the interactive relationship described in Figure 3B and the process of creating an IP interactive TV center program in an open way for users, participating in the program process of an IP interactive TV program in an open way for users, and performing an interactive TV program in an open way by the system. Specific details of the billing/payment process and resulting IP personal wealth (or value) index.

Figure 3B illustrates the detailed steps of the key process shown in Figure 3A. In this illustration, more detailed process steps about the formed interaction relationship 4 in FIG. 3A are mainly explained.

For the interactive relationship between the interactive TV host, the interactive TV viewer and the interactive billing and payment device, the system follows the priority of the main control server record (4.1 as shown in Figure 3B) and the IP interactive TV billing record first priority. Two priorities (4.2 as shown in Figure 3B) and) principles, mirroring the final transaction record results to the host of the interactive TV program (4.3 as shown in Figure 3B).

For Figure 4.1, it controls the user interaction process, that is, when the user just participates in an IP interactive TV program, as shown in Figure 3A, a new record about the start of the transaction between the two parties is generated in the main control server, and indicates that both parties The interactive application service is normal, that is, the user (viewer) can normally receive the audio and video information sent by the host, and at the same time, can also normally send his own audio and video information to the host and other interactive TV viewers.

For 4.2 in the figure, the interactive fee expenditure is recorded through the communication with the main control server. Here, his own record is the second priority: that is, once the host’s information is not received within a predetermined time, a notification will be sent to the master server to request it to stop timing and billing. , the mirror record at the host should also stop billing, so, through the principle of first and second priority, any record based on this billing can be based on this to realize the billing and payment of tariffs. At the same time, if the viewer receives the host's information again, they will also notify the main control server to continue timing and billing, and the main control server will record these information in the database. Record.

With such a "server first priority record" process, and through a "viewer record second priority" process, all feed-based records are complete and authentic. That is, as long as there is a flow of information, there will be a record of information charges. When the flow of information stops, the processing of timing and billing by the system will also stop. Then, through these records of the server, the system uses the billing and payment device to realize the information fee generated between the host and the audience due to the flow of information information, calculate and allocate it, and use the growth of the wealth (value) index Reflected.

On the user side, in order to realize this "billing record second priority" processing, he must also use the following judging devices:

● Judgment device for normal audio playback;

● Video normal playback judging device;

● Recording/sending normal judgment device;

● Video collection/transmission normal judgment device;

For the details of these judging devices, refer to FIG. 3C.

For the mirror record of the host, the record of the user (viewer) shall prevail. Once the user receives the information or plays abnormally, the billing process will stop (time pause). When the user can receive and play the information normally, the billing Resume (timed start).

In this way, as long as there is a normal flow of information at the iTV supporters and iTV viewers, the information fee will be generated. If the information flow stops or the flow is abnormal, the system will also stop the processing of timing and billing for it, that is, no information will be generated. At the same time, users can see the specific situation and specific amount of information fees that they can actually receive or pay at any time. See Figure 3C for details on this point.

At the same time, there is a billing/paying device running in the main control server, through which, the corresponding records are found in the database, and the calculation and fund transfer are carried out. In this way, the information fee generated between the host and the audience is successfully reduced The injection or deduction in its account also realizes the growth of personal wealth (value) index on the Internet.

Figure 3c shows a more detailed detail of the key parts of Figure 3b. In this figure, the details about the key parts in Fig. 3B are mainly explained, and these key parts are: several judgment devices at the user end and dynamic display devices for income/expenditure.

Specifically, these judging devices are:

● Judgment device for normal audio playback;

● Video normal playback judging device;

● Recording/sending normal judgment device;

● Video collection/transmission normal judgment device;

Wherein: the audio frequency normal playing judging device is used for judging whether the audience can normally receive the audio signal sent by the host, which is processed by the data received by the audio port number, on the other hand, if the audio data is received through the audio port, It is also necessary to determine whether the client is playing this normally.

Equally, the video normal play judging device is used to judge whether the viewer can normally receive the video signal sent by the host, which is processed by the data received by the video port number, on the other hand, if the video data is received through the video port, It is also necessary to determine whether the user terminal is playing this normally, that is, displaying it on the screen.

The above two devices are for judging whether the user listens to the news information normally. If the viewer is sending audio and video information at this time, it will be processed by the following two judging devices.

The recording/sending normal judging device is used to judge whether the user is normal when sending out the audio data. This judges whether the user's recording is normal, and then judges whether the recorded audio data can be sent out normally.

The video collection/transmission normal judging device is used to judge whether the user is normal when sending out video data. This is by judging whether the user terminal is collecting video data normally, and then judging whether the collected video data can be sent out normally.

If the result of all these judgments is abnormal, the billing and payment device of the main control server will be notified, that is, a message packet is sent to the main control server, and its content includes:

● User ID number;

● Name of iTV center;

● Sign: stop billing or start billing;

After receiving the information, the main control server notifies the billing and payment device, and then the billing and payment device notifies the timing device to start timing or stop timing according to the information sent by the user, so that the processing of whether to pay is also controlled.

Through the above several judging devices, it can be determined whether the user is receiving and sending data normally during the interaction, and according to the situation, the main control server is notified to perform timing, etc., and the user's record is treated as the "second priority". At the same time, the records for the server are treated as the first priority.

In this way, through these two priorities, the accuracy and effectiveness of the relevant billing/payment records can always be guaranteed, and at the same time, the credibility of the IP personal wealth (value) index derived therefrom can also be guaranteed.

In addition, there is also a device for dynamically displaying income (for the host) and dynamically displaying expenditure (for the audience) for the host client and the user (viewer) client. Have an intuitive understanding of your income and expenses.

In this device, if the user's information playback or information transmission is normal, the user's income and expenditure from the beginning of participating in the interactive TV or creating the interactive TV to the present will be dynamically displayed on the user end. increased by growth. If the information is not sent normally, the income and expenditure situation will not continue to grow (ie, no income and no expenditure during this period).

For the host, what he shows is the information fee that all current users (viewers) who participate in the interactive TV will pay him;

Through these processes, it is truly realized that any user can create interactive TV, and any user can also participate in interactive TV, and then, through the interactive billing device, the host of interactive TV can also receive information from any audience participating in his interactive TV cost.

Fig. 4 illustrates the flow chart of the user's open creation of an IP interactive TV center (user and main control server). When a special user (forwarding server) logs into the system, that is, the system has enough forwarding server resources, any user who logs in to the system can create IP interactive TV center programs by himself, and the system has no restrictions on them. This also shows that the system is open to creating an IP interactive TV center, and its position in the system architecture is shown in Figure 3A.

In order to form the logical relationship with the audience and the logical relationship with the billing and payment device, the system must first create an IP interactive TV center, and through this entity, the logical relationship 1 and logical relationship 2 shown in Figure 3A can be formed. How the user/system creates this interactive TV center entity will be introduced in detail below in FIG. 4 and FIG. 5 .

In Fig. 4, it mainly illustrates the service control flow between the user who creates the IP interactive TV center and the main control server, specifically as follows:

When a user who logs into the system wants to create his own IP interactive TV center, the user must first press the "Create IP Interactive TV Center" button, and the system will pop up the "Create IP Interactive TV Center" dialog box. Before the control server submits the creation command, it must fill in the creation information, which includes:

● The name of the created IP interactive television center;

● The password (if necessary) required by other users to participate in the IP interactive TV center;

● Other users need to pay the price per unit time to participate in the IP interactive TV center;

After the user fills in the information, he can press the "Create" button in the "User Create IP Interactive TV Center" dialog box. At this time, the user program will send the "Create" message to the main control server.

After pressing the "Create" button, the client program first checks this information before sending it to the master server. If the information filled by the user is insufficient, the client program will remind the user to fill in the information. Among them, in this system, the name of the IP interactive TV center and the price that other users need to pay per unit time to participate in the IP interactive TV center must be provided by the user.

In the main control server, when the main control server receives the information submitted by the user, it will enter the background processing of the system through command analysis, that is, schedule and control. The specific process is as follows:

The main control server first searches the forwarding server resources logged into the system in the forwarding server login record table (specialloginfo), and judges whether there is an idle server (that is, a forwarding server that has not provided services for other users) through the flags in the table (There must be at least two forwarding servers, one as the IP interactive TV center hosting terminal, and the other as the information sending terminal of the IP interactive TV center), if the system does not have idle forwarding server resources, the main control server will return the system forwarding Insufficient server resources, the return information that the user failed to create an IP interactive TV center.

If the system has idle forwarding server resources, find out the information registered by the system in the background of the main control server, such as the IP address of the forwarding server, command and control port information, etc., and then, the system sends one of the IP addresses and ports (ie A forwarding server, because the IP and port can uniquely identify a server) Send a command request to create a forwarding server host end, use the forwarding server as the host end server of this IP interactive TV center, and send to another IP address and port at the same time Create a command request at the sending end of the forwarding server, and use the forwarding server as the sending end server of the IP interactive TV center.

When the host server and the sender server receive the command request from the master server, they will process and schedule internally, and return the results to the master server after completion (see Figure 5 for details of these processes).

After the main control server receives the processing result of the forwarding server, if the forwarding server fails to process (as long as one of them fails), the main control server returns to the user the information that the creation of the IP interactive TV center fails.

If the processing by the forwarding server is successful, the master control server will communicate with the hosting end of the forwarding server again, and send the user information and the information of the sending end of the forwarding server to the hosting end. These information include:

● ID number;

● IP address;

● command port number;

● audio port number;

● Video port number;

The hosting end adds the information to the target queue for sending information, so that the forwarding server can send the received information to the forwarding server sending end and the user (i.e., the IP interactive TV host), and the system passes through the forwarding server sending end, The received information is forwarded to the IP interactive TV audience (so the audience information for the IP interactive TV program will be added to the sending information target queue of the forwarding server sending end, and this point is described in detail in Figure 6) .

The next thing to be done by the main control server is to record these information in the database, specifically, the meetinginfo table and the meetcountinfo table will be used so that users can query and use them when participating in the IP interactive TV center, especially the main control server. Communicate with the sending end of the forwarding server, and add the participant's information to the sending information queue of the sending end.

For the meetinginfo table, it is mainly used to record the information of the IP interactive TV center, such as the host ID, IP, and the name of the IP interactive TV center. See Figure 12 for a detailed description of the table structure.

For the meetcountinfo table, the system uses this table to load balance the audience newly added to the IP interactive TV center (for how the system performs load balancing, see Figure 6 for details), and then distributes the forwarding server sending end, and sends the audience Added to the sender's send message target list.

After the main control server records all these information into the database, it will return to the user the information that the IP interactive TV center is successfully created, including:

● The IP address of the hosting end of the forwarding server:

● The forwarding command control port of the forwarding server:

● Forwarding the audio forwarding port of the calling end of the server:

● The video forwarding port of the forwarding server:

● The IP address of the sending end of the forwarding server:

● The forwarding command control port of the sending end of the forwarding server:

● Forward the audio forwarding port of the sending end of the server:

● The video forwarding port of the sending end of the forwarding server:

The user (the host of the IP interactive TV program at this time) records the information locally, so that the user's IP interactive TV center is created, and the user (the host) can send the audio and video to the host terminal of the forwarding server. information, and send it to the sending end of the forwarding server through the calling end of the forwarding server, and then send it to the user (that is, the IP interactive TV viewer) through the sending end, so as to realize the sending of the audio and video information of the host of the IP interactive TV center. For the data flow process, refer to the description in FIG. 8 .

Figure 5 illustrates the flow chart of the user's open creation of an IP interactive TV center (main control server and forwarding server).

When a user creates an IP interactive TV center, the main control server communicates with the forwarding server through command control, and the forwarding server allocates forwarding resources for the IP interactive TV center created by the user through internal scheduling and control. When the user ends the IP interactive TV When the center is set, the master control server will notify the forwarding server to release the allocated resources, and the system can schedule the server to serve other users again. For other communications between the main control server and the forwarding server, the implementation process is basically the same: that is, the forwarding server performs corresponding processing according to different control commands sent by the main control server. The specific process is as follows:

When the main control server receives the user's creation command, the main control server first analyzes the command, enters the background processing, and performs internal scheduling and control (see Figure 3A). Then communicate with the forwarding server.

When the master control server communicates with the forwarding server, the master control server must first determine whether it is the calling server or the sending server to communicate with, and then send different control commands.

For the sending end server, the master control server requires it to create an IP interactive TV center sending end forwarding server. After receiving the command, the forwarding server first allocates resources for the IP interactive center, which includes:

● Initialize and clear the target queue for sending information;

● Activate forwarding service;

When the sending end of the forwarding server processes the information successfully, it sends a processing success message to the main control server, indicating that the forwarding server at the sending end is ready to provide information forwarding services for users. At this point, the sending end of the forwarding server has been created (or allocated) successfully.

For the host server, the master control server requires it to create an IP interactive TV center host forwarding server. When the forwarding server receives the control command, it first allocates resources for the IP interactive center, which includes:

● Initialize and clear the target queue for sending information;

● Activate forwarding service;

When the forwarding server successfully processes the information, it will send a successful message to the main control server, indicating that the resource allocation of the forwarding server at the hosting end is successful, and audio and video information can be received and forwarded. Wait for the information from the program host of the IP interactive TV center and the sending end of the forwarding server, and add them to the sending target queue.

After the main control server receives the return information that both the calling end of the forwarding server and the sending end have successfully created, the main control server registers the destination of the information to be sent to the holding end of the forwarding server, which includes the founder (host) of the IP interactive TV center Information and information on the sender side of the forwarding server, these information are:

● The ID number of the sending end of the user/forwarding server:

● The IP address of the sending end of the user/forwarding server:

● The command port number of the sending end of the user/forwarding server:

● The audio port number of the sending end of the user/relay server:

● The video port number of the sending end of the user/relay server:

Among these information, the host terminal of the forwarding server sends the information target queue to use the ID number as its keyword. If the IP address, command port, audio port, and video port of the IP interactive TV program supporter change, the system will pass the main control The server controls and sends a control command to the caller of the forwarding server. The command information includes:

● ID number

● IP address;

● command port;

● audio port;

● Video port;

At this time, the calling end of the forwarding server locates the target queue for sending information according to the ID number transmitted, and then updates the information marked with the ID with the newly transmitted information.

If the system performs load balancing according to the number of viewers participating, and adds a forwarding server sending end, it also needs to communicate with the forwarding server through the main control server, and transfer the information of the forwarding server sending end (as mentioned above, including the ID) , IP address, port information) to the information sending target queue of the hosting end of the forwarding server, so that the sending end of the forwarding server can send the information to the sending end of the newly added forwarding server, and then forward the information to the sending end through the sending end. The IP interactive TV viewer at the sending end. Refer to FIG. 6 for details about the load balancing performed by the main control server when the user joins the IP interactive TV center.

After the main control server sends the information to the forwarding server successfully, the communication between the main control server and the forwarding server is completed.

So far, the system has completed the creation of the IP interactive TV center by the user through the detailed process and processing devices described in the above figure and the figure, and the creator can use the IP interactive TV center to communicate with other users distributed on the Internet for personal information communicated with. That is to say, the audio and video information of the program host of the IP interactive TV center is first sent to the hosting end of the forwarding server, and the forwarding server searches for the information filled in the target queue of the information it sends, and finds out the destination to which the received information is forwarded in a loop (at the host end of the forwarding server, the sending destination of the information includes the host of the IP interactive TV program and the sending end of the forwarding server) information, these information include IP address, audio port number, video port number, etc., and then the sending end of the forwarding server sends The received audio and video information is forwarded to the audio port and video port corresponding to the corresponding IP address, that is, sent to the sending end of the forwarding server (or the host of the IP interactive TV program). Similarly, the sending end of the forwarding server receives the audio and video information, look for the information that is filled in the target queue for sending information, and find out the destination to which the received information will be forwarded in a loop (at the sending end of the forwarding server, the destination of the sending information includes all the IP interactions added to the sending end TV audience) information, these information include IP address, audio port number, video port number, etc., then the forwarding server sender forwards the received audio and video information to the audio port and video port corresponding to the corresponding IP address, that is IP Interactive TV Viewership.

By successfully creating the entity of the interactive center, conditions are created for the formation of logical relationship 1 and logical relationship 2 described in Figure 3A, once a user joins the IP interactive TV program, the Logical relationship 1, in addition, once the billing/payment means of the system is activated, logical relationship 2 described in Fig. 3A will be formed.

Fig. 6 illustrates the flow chart of users participating in the IP interactive TV center openly (main control server, viewer and forwarding server).

For users who want to participate in the IP interactive TV center (that is, become IP interactive TV viewers), he must also first register in the system, and then log in to the system. Of course, the system needs to carry out processes such as identity verification for the user. An illustration of these processes or flows is described in Figure 3A.

Because in this system, for any user distributed on the Internet, he can join the IP interactive TV center program created by any user through this system, so it is open, and there is no restriction on the addition of users (of course He also has to register and log into this system). The positions of users participating in IP interactive TV programs in the system architecture are shown in FIG. 3A .

In order to form a logical relationship with the host and a logical relationship with the billing and payment device, the system allows any user to join the IP interactive TV center, and only through the user's joining can the logical relationship 1 and logical relationship 3 shown in Figure 3A be formed. The following will introduce in detail how the user/system can freely participate in the programs of the IP interactive TV center.

When a user logs in successfully, he can not only view the name of the IP interactive TV, but also choose one to join, and can also store some IP interactive TV programs into his favorites, so that when the user logs in again, the main control server will actively Send the latest detailed information of the IP interactive TV to these users. All of these are automatically completed in the background of the main control server according to the situation of different users, and the relevant information results are recorded in the relevant database. When the user logs in next time , to notify the user. See Figure 7 for details on querying and saving.

When a user wants to participate in the program of the IP interactive TV center, he first submits to the main control server a control command to participate in the IP interactive TV (that is, becomes a viewer of the IP interactive TV), and submits the following information to the main control server:

● The ID identification number of the user;

● The name of the IP Interactive Television Center program to participate in;

After the main control server receives the user command, the main control server will search in the IP interactive TV information table (meetinginfo) according to the name provided by the user through background scheduling and control, and the condition is: f_meetname is equal to the IP interactive TV provided by the user The name.

When the record is found, it is also necessary to find out the information of the corresponding moderator in the record and the host and sender of the forwarding server. These information include:

● IP address of host of IP Interactive TV Center:

● The command port number of the host of the IP interactive TV center:

● The audio port number of the host of the IP interactive TV center:

● The video port number of the host of the IP interactive TV center:

● The IP address of the hosting end of the forwarding server:

● Forwarding the command and control port of the calling end of the server:

● Forwarding the audio forwarding port of the calling end of the server:

● The video forwarding port of the forwarding server:

● The IP address of the sending end of the forwarding server:

● Forward the command and control port of the sending end of the server:

● Forward the audio forwarding port of the sending end of the server:

● The video forwarding port of the sending end of the forwarding server:

Then, the system needs to perform load balancing scheduling sent by the forwarding server for the user to participate in the program of the IP interactive TV center. The forwarding server with the least number of senders is in the target queue for sending information.

For load balancing, the master server first finds the record of the sending end of the forwarding server with the least number of participants according to the count table (meetcountinfo) of the sending end, and queries relevant information, including:

● The IP address of the sending end of the forwarding server;

● The command port number of the sending end of the forwarding server;

Then the main control server communicates with the sending end of the forwarding server (a PC can be uniquely identified through the IP address and command port number, that is, the server), and adds the information of the users who want to participate in the program of the IP interactive TV center to the forwarding server to send In the target queue of sending information on the terminal, the information includes:

● ID number of the participant:

● Participant's IP address:

● The command and control port number of the participant

● Participant's audio message port number

● The video information port number of the participant

Wherein, the ID number of the user is used as the primary key in the information sending target queue of the sending end. In this way, the sending end will forward the received information (by cyclically finding out the destination of information forwarding from the sending information target queue) to the node identified by the IP address and port, that is, to the user.

In addition, if when the user wants to participate in the program of the IP interactive TV center, the sending information target queue of the sending end of the forwarding server allocated by the system for the interactive TV is full, that is, the load of the sending end has reached the maximum state. The interactive TV center then allocates a forwarding server sending end to provide services for it.

At this time, the system will check whether there is any free resource in the special user login record table. If there is no free resource, the system will return to the user the information that joining the IP interactive TV program fails due to insufficient system resources. If the system still has idle resources, select one as another forwarding server sender for the program of the IP interactive TV center, and find out the following information:

● ID number;

● IP address;

● command control port;

● audio forwarding port;

● Video forwarding port;

The main control server communicates with the forwarding server through the command port, and requires it to provide information forwarding services for the IP interactive TV center as a sender. When the forwarding server receives the information, it allocates resources for the IP interactive TV center, such as Activate the audio and video sockets, initialize the sending target queue of the forwarding server, etc., and then return a success message to the master server, at this time, the sending end of the forwarding server is ready.

When the main control server receives the information that the forwarding server is ready, it will send the information of the user who wants to join the interactive TV program to the sending end, which also includes:

● ID number of the participant:

● Participant's IP address:

● The command and control port number of the participant

● Participant's audio message port number

● The video information port number of the participant

The sending end of the forwarding server fills the sending target queue according to the sending target information from the master server, so that once information is sent to the forwarding server, the forwarding server forwards the information to the corresponding destination in turn according to the sending target queue .

After the master control server and forwarding server sender communication successfully completed, the master control server will record relevant information in the database, specifically, insert a new record in the IP interactive TV participation user information table (attendinfo), The recorded information includes:

● The ID number of the creator (host) of IP interactive TV:

● IP interactive TV name:

● Participating user ID number:

● Participating users' IP addresses:

● The command port number of the participating user:

● The audio port number of the participating user:

● Video port number of participating users:

Then update the sending user count (plus 1) of the forwarding server sending end in the counter table (meetcountinfo). If it is a newly allocated forwarding server, a new record will be inserted in the table (its user count is 1).

After the master control server updates the relevant records in the database, the master control server will return relevant information to the user, which includes:

● IP address of host of IP Interactive TV Center:

● The command port number of the host of the IP interactive TV center:

● The audio port number of the host of the IP interactive TV center:

● The video port number of the host of the IP interactive TV center:

● The IP address of the hosting end of the forwarding server:

● The command port number of the calling terminal of the forwarding server:

● The audio forwarding port number of the calling end of the forwarding server:

● The video forwarding port number of the calling end of the forwarding server:

● The IP address of the sending end of the forwarding server:

● The command port number of the sending end of the forwarding server:

● The audio forwarding port number of the sending end of the forwarding server:

● The video forwarding port number of the sending end of the forwarding server:

After the user receives the information, the client program records the information locally. At this time, the user has successfully participated in the IP interactive TV, and can also receive the information sent by the creator (host) of the IP interactive TV. data.

Similarly, if the user participating in the interactive TV program wants to quit the interactive TV program, he will also send a control command to the main control server. Just delete it from the target queue (uniquely identified by the user's ID number). It also disconnects the connection and flow of the data flow between the sending end of the forwarding server and the user.

If the user successfully participates in the program of the interactive TV center, conditions are created for the formation of logical relationship 1 and logical relationship 3 described in Figure 3A, and once the user joins the IP interactive TV program, the Logical relationship 1, in addition, once the billing/payment means of the system is activated, logical relationship 3 described in Fig. 3A will be formed.

Similarly, through the creation of the interactive TV center by the user illustrated in Figure 4 and Figure 5, and the participation of the user in the program of the interactive TV center illustrated in Figure 6, the logical relationship 1 described in Figure 3A has been formed, if the billing/payment of the system When the device is started, the logical relationship 4 described in Fig. 3A (see Fig. 3B and C for details) can be generated, that is, any user can create an interactive TV, and any user can also participate in the interactive TV, and then, through the interactive billing device, interactive TV hosts are also able to receive information fees from any viewers who participate in their interactive television. Thereby realizing the growth of personal wealth (value) index.

Fig. 7 illustrates the flow chart of the user's open participation in the IP interactive TV center (spectator, query/collection and master control server).

The query/collection of the IP interactive TV center is to search for the created IP interactive TV programs registered on the main control server in the database of the main control server, and then transmit them to the user. If the user has a certain IP interactive TV center program If you are interested, you can collect it. At this time, the main control server sends the IP interactive TV program information content that these users are interested in to the user. The latest information on the programming of the IP Interactive Television Center. Specifically as follows:

After the user logs into the system (certainly through identity recognition and other processing processes), the user sends a control command to query the programs of the IP interactive TV center to the main control server, which is first sent to the main control server through the user interactive environment device.

When the main control server receives the information, it also enters the background control, scheduling and processing through the interactive environment device:

First, go to the IP interactive TV center information record table (meetinginfo) to query, that is, to query the information required by the user, and then return it to the user. The information includes:

●IP interactive TV host name:

●Program name of IP Interactive TV Center:

●Price per unit time and other information:

After the main control server queries the information, it sends it to the user. Users can bookmark the IP interactive TV programs they are interested in according to their preferences and interests, so that they can browse offline or receive the latest information about the IP interactive TV center programs when they log in next time.

When the user wants to collect IP interactive TV center programs, he first selects a program, and sends the control command information to the main control server through the user interactive environment device.

When the main control server receives the control command information, it searches in the IP interactive TV center information record table according to the name of the IP interactive TV that the user wants to collect. After finding it, the main control server records the relevant information through the IP collection device and sends it to At the user, the user records the information locally. In this way, the user can browse the program of the IP interactive TV center offline locally.

On the other hand, when the user collects, the main control server uses the IP collection device to record the relevant information about the user's collection in the database, which includes:

● User ID number:

● The name of the favorite IP interactive TV center program:

● IP interactive TV host information:

● Collection catalog ID number:

● and other relevant information

In the background of the main control server, there is also a matching device running. Its function is to scan and record the IP interactive TV collection user information table and the IP interactive TV information record table cyclically, and match the information of the two. The optimized information of the user's collection is recorded to form IP collection notification information, and through the IP collection device, when the user is online, the user is notified of the latest information in time. This is another level of interaction in this system.

FIG. 7B illustrates the detailed flow of the interactive video image device. In this figure, it mainly illustrates some details of the system’s processing of video images. Through them, the system can capture an image from some video information during the transmission of the system at regular intervals, and send it to those who need it. The user of the image, after the user receives the image, save it locally for browsing when leaving the interactive TV center program or directly display the image on the user's screen.

In this video image device, several aspects of the system, such as the user, the main control server, and the forwarding server, are basically involved, as well as the communication and control among them, and these aspects and their interrelationships are described in more detail in other diagrams The description here mainly explains the details of the implementation and flow of the device:

First of all, the user must register his image request with the main control server. Of course, the ID number of the user is used as the identification. Use the ID to locate the record and query the relevant information of the user, which includes:

● The ID number of the forwarding server where the user is located;

● The IP address of the forwarding server where the user is located;

● The command and control port of the forwarding server where the user is located;

After the main control server inquires about these information, it will notify the forwarding server where the user participates in the interactive TV program (IP address and command port inquired out above).

After receiving the notification request from the main control server, the forwarding server identifies the user with the ID number, takes out the user's information from the server's information sending queue, and updates the user's information requirements, that is, the user identified by the ID as the On the sign, indicating that the user needs video image information.

After the forwarding server updates the queue record, it returns to the main control server. After receiving the returned information, the main control server records the user's information demand information in the database, and then returns a success message to the user who made the request. , or return a failure message. After the user receives the success message, he can save the video images captured by the system regularly, and through the user's control, either display these images in real time, or browse after leaving the interactive TV program.

On the other hand, when the forwarding server receives video information, it first judges whether the received video information is a video image. The user information of the image is sent, and this information includes:

● User ID number;

● Identification of user demand information;

● User IP address;

● User video port number;

● User audio port number;

After the forwarding server finds out the information, it judges whether to send it to the user according to the user's demand information identifier and the type of information to be forwarded, and if it wants to send it, it sends the information to the found IP address and the corresponding port. That is, the user.

On the user side, when the received information is video image information, he first saves the image locally, and then according to the user's control, the received video image information can be displayed on the screen in real time, or can be After the user leaves the IP interactive TV program, he can browse offline locally.

In this way, through this video image device, a high-efficiency high-definition application method is provided for narrow-band video applications, which not only allows users to see dynamic video information when participating in IP interactive TV programs, but also allows users to save some video Images, for offline viewing or as a permanent reference.

Fig. 7C illustrates the flow of the broadband judging device. In this figure, it mainly illustrates a device for "storing food for the people" adopted by the system in order to utilize the resources of broadband users. Through it, the forwarding server can perform information forwarding services in the background of broadband users.

This device is activated after the user successfully logs into the system and completes the registration of his personal information. The specific process is as follows:

The device first judges whether the user's current network status is a broadband network, that is, judges the user's network bandwidth. When it is within a certain range (for example, 512K), the user can be recognized as a broadband user, and the system can carry out The forwarding of service information will not affect the user's normal use of the network (because the network bandwidth is sufficient). Of course, if the system determines that the user is not a broadband user after judgment, the device is turned off, and this process ends.

If the user is a broadband user, in order to realize the information forwarding service at the user end, three communication sockets must first be created:

● command control socket;

● audio forwarding socket;

● Video forwarding socket;

After the client program has created these sockets, it needs to register with the main control server, indicating that the user can act as a forwarding server in its background to provide information forwarding services for other users.

At this time, record the ID number of the forwarding server in the user section, and add an identification (such as adding an 'S' after the user's ID number) to the ID number of the user, so that the forwarding server also has a unique ID number in the system. The identification ID number.

When the client program is finished processing, it is necessary to issue a registration command to the master server, that is, to use the three sockets just created to register and register the user's forwarding information, which includes:

● The ID number of the forwarding server;

● forwarding service control command port number;

● forwarding service audio port number;

● forwarding service video port number;

For any one of the sockets, a registration command is issued to the socket command control port of the master server, and the unique ID of the forwarding server specified by the client word is used to identify which forwarding the command received by the master server belongs to. The ID number issued by the server is similarly identified by the ID number when the master server operates the database.

After the main control server receives these information, it is recorded in the database. After all these information are registered, the main control server sets the flag position of the record information to indicate that the forwarding server can perform the forwarding service. When the system is dispatching, the information is found out from the record table and processed.

Of course, the master control server will also return these registration information to the client, and the client program will also record these information.

So far, the processing process of the broadband judging device is completed, and the forwarding service of service information can be performed in the background of the user.

Figure 8 illustrates the overall data flow chart of the IP interactive TV center (host, audience and forwarding server).

In this illustration, the flow of information data flow between the interactive TV program supporter and the interactive TV viewer is mainly explained, that is, the data flow process between logical relationship 1 in FIG. 3A .

Once the IP interactive TV center is created, and at the same time there are users participating in the IP interactive TV center (that is, the IP interactive TV center has viewers), the data flow between them (that is, the host of the IP interactive TV center and the IP interactive TV audience) It has nothing to do with the main control server. It just forwards the information through the forwarding server, that is, sends the information of the host to the audience, or sends the information of the audience to the host and other audiences. In this way, through the framework structure and topological relationship of the system, the goal of the system is realized: not only can I get the world, but also let the world see me!

There are two main aspects in the data flow of this system. One is that the IP interactive TV program host sends audio and video information to IP interactive TV viewers, and the IP interactive TV viewer can send IP interactive TV hosts and other IP interactive TV viewers Send audio and video information. At the same time, for these audio and video information, it also allows the superposition of more than one corresponding information. The specific data flow is as follows:

When the program host of the IP interactive TV center sends information, he sends his own audio and video information to the host end of the forwarding server. When the host end receives the audio and video information, he checks his own internal sending information target queue, and circulates from the queue Take out the sending destination and send the information to the destination.

At the host end of the forwarding server, its sending information target queue includes the destination of the host of the IP interactive TV center and the destination of the sending end of the forwarding server, and when the host is sending information, the hosting end of the forwarding server will not send the information to IP interactive TV center program host, but only sent to the sending end of the forwarding server.

When the sending end of the forwarding server receives the audio and video information, it checks its internal sending information target queue, takes out the sending destination from the queue in a loop, and sends the information to the destination.

At the sending end of the forwarding server, its sending information target queue only includes the destinations of IP interactive TV viewers. In this way, the transmitting end of the forwarding server sends the audio and video information to the IP interactive TV audience.

When IP interactive TV viewers need to send information or IP interactive TV center program hosts require viewers to send information, at this time, IP interactive TV center program hosts can control and dispatch these information as the control center.

When an IP interactive TV viewer needs to send information, he first sends a request to send information command to the command control port of the program host of the IP interactive TV center. The control command indicates that the audio and video information received by the host terminal of the forwarding server shall be sent to the host. At the same time, the host of the IP interactive TV center shall also send a consent message to the viewer who issued the request. When the viewer receives After agreeing to the information, he first sends a control command to the sending end of the main server where he is located, indicating that the audio and video information received thereafter will not be sent to the audience, and then the audience can send audio to the hosting end of the forwarding server and video information. In this way, the audience's audio and video information is sent to the host of the IP interactive TV center and the forwarding server sending end through the forwarding server, and then the audience's audio and video information is forwarded to other users through the forwarding server. IP Interactive TV Viewership.

For ending the process of sending information to the viewer, the processing flow is similar, except that the control command is reversed.

Fig. 9A illustrates the billing/payment device flow of the IP interactive TV center. Another important aspect of the system of the present invention lies in the flow of corresponding tariffs and the flow of billing and payment processing devices generated during the information exchange of such users distributed on the Internet. Through him, the IP interactive TV center The program host and IP interactive TV viewers can not only successfully interact with information, but also interact with the charges generated thereby. Realize the growth of users' wealth and value on the Internet (that is, the value of IP interaction value). See Figure 10 and Figure 11 for details about the value index (or wealth index) device of this system.

That is to say, after the system starts the billing/payment device, he not only realizes the logical relationship (that is, the logical relationship 2 in Fig. 3A) with the host, but also realizes the logical relationship (that is, the logical relationship 2 in Fig. 3A) with the interactive TV viewer. Logical relationship 3), at the same time, through the description of Figure 4, Figure 5 and Figure 6, the core of the system is realized: logical relationship 4 in Figure 3A (see Figure 3B and C for details), that is, any user can create Interactive TV, any user can also participate in interactive TV, and then, through the interactive billing device, the interactive TV host can also receive information fees from any viewer who participates in his interactive TV. Achieve exponential growth in personal wealth or value.

The billing and payment process of this system is now simply described as follows, and its more detailed description please refer to another "About a billing/paying/bargaining method on the Internet" patent.

In this system, if a user successfully creates an IP interactive TV center program (the specific process of creating an IP interactive TV center is described in Figure 4 and Figure 5), and when another user becomes the IP interactive TV program When a viewer (successfully participated in an IP interactive TV program, refer to Figure 6 and Figure 7 for the detailed flow of the user's participation in the IP interactive TV center program), there is a user transaction record table (bargaininfo) record in the main control server Next viewer's transaction information, including:

● Billing party ID number:

● Payer ID number:

● Paid price per unit time:

● Start time:

● End time:

● Flags:

When the user joins the IP interactive TV program at the beginning, the main control server just inserts a new record in the bargaininfo table, wherein,

● The "ID number of the charging party" field is filled with the ID number of the host of the IP interactive TV program that the user participates in;

● The "ID number of the payer" field is filled with the ID number of the user (i.e. the IP interactive TV viewer) participating in the IP interactive TV program;

● The price paid per unit time refers to the price that other users designated by the host of the IP interactive TV program to participate in the program of the IP interactive TV center need to pay per unit time when creating the IP interactive TV program;

● The "start time" field is the current time of the system when the user successfully joins the IP interactive TV program;

● When the user leaves the IP interactive program or the host ends the program, the system will update the record, fill the "End Time" field in the table with the current time of the system, and update the flag;

Like this, this article relates to the transaction record between the IP interactive TV host and the viewer and just formed, and when the flag bit is reset (for 1), that is, the "end time" field has been filled with data, so a complete article has been generated Transaction Record.

At the same time, a scanning program is run in the background of the main control server of the system to scan the database transaction record table (bargaininfo) cyclically. Once a certain record in the table is complete (judged according to the billing and payment flag field), the The record is processed in the control server. The specific process is as follows:

First, the system takes out each field of the record, including:

● Billing party ID number:

● Payer ID number:

● Paid price per unit time:

● Start time:

● End time:

● Flags:

The system then calculates the total fee for the transaction by:

① Calculate the time difference: end time minus start time;

② Conversion unit: Convert the time difference into "minutes" as the unit, because the unit time payment price refers to the payment price per minute;

③ Get the total cost: multiply the price per unit time by the time difference;

When the calculation is successfully completed, the system first generates a new record in the payment record table, and the recorded information includes:

● Billing party ID number:

● Payer ID number:

● Total payment:

● Flags:

Among them, the ID number of the charging party is the ID number of the host of the IP interactive TV center; the ID number of the paying party is the ID number of the audience of the IP interactive TV center; the total amount of payment is the total amount of the fee just calculated; the flag is "" when a new record is inserted 0" value.

When the system successfully inserts the record in the payment record table, it will backup the corresponding record in the transaction information record table and write it into the transaction information backup table for future query. In the backup table, in addition to recording all the contents of the transaction information table, the creation time of the piece of information is also recorded, and the creation time is filled with the system time when the backup record is inserted.

After the system has backed up the transaction information, it will also delete the record from the transaction information record table.

In this way, the charging process of the system is completed.

Next, the system will process the payment. This will query the total amount of the payment, the payer, and the ID number of the payer from the payment record table. Then, the system will deduct the payable amount from the payer's IP personal account. The amount, and then add the corresponding funds to the IP personal account of the charging party. In this way, the transfer operation of paid funds is completed.

When the funds are successfully transferred, the system will also back up the corresponding records in the payment record table, and delete the corresponding records from the payment record table after the backup is successful.

So far, the billing and payment processes of the system are all over. It also successfully completes the capital flow between IP interactive TV creators (hosts) and IP interactive TV viewers (participants). And through this flow of funds, the growth of personal wealth and value of distributed users on the Internet has been successfully realized.

For this kind of wealth and value, the system is reflected through the wealth index (or value index) device. At the same time, users can query the wealth index (or value index) of other users or their own through the system, and through it, users can judge their activity on the Internet. Wealth and value on the Internet, which completely ignores all uncertain factors such as the user's name, gender, age, etc. on the Internet and unverifiable information in personal registration. See Figure 10 and Figure 11 for more detailed information about the IP personal value index device.

Figure 9B illustrates an IP personal account identification device. In this illustration, Xiangxi explains the process of identifying the user's personal account. Through him, the user can know the general situation of the funds in the personal account of the user who communicates with it, and use this to determine whether it should be disconnected. Or continue to trade information with him. This is also an auxiliary means or means to the billing and payment means.

The specific implementation process is as follows:

When a user wants to join an IP interactive TV program, it can check the general situation of the personal account of the host or other users, which is accomplished by communicating with the master control server. When the main control server receives the user's request, it will query the user's account fund record table, and return the result of the query to the user.

On the user side, the program uses different colors for display according to the specific situation of the user. For example, in this system, if the user's account balance is below 10 yuan, it will be displayed in red, indicating that the user's account balance is not enough for long-term information exchange or transactions; if the user's account balance is below 100 yuan, it will be displayed in red. If it is displayed in yellow, it indicates that the user's account balance can be exchanged or traded for a period of time; if the user's account balance is more than 100 yuan, it will be displayed in green, indicating that the user's account balance can be used for a longer period of information exchange or transaction. For transactions, users can safely share information with them.

At the same time, when the user joins the IP interactive TV program, the change of the user's account funds will be dynamically displayed. That is, in this information exchange and transaction, through the billing/payment device, the user can know the general situation of the user's account funds in real time. For example, if the user's account funds are reduced to less than ten yuan due to the user's expenses, other related users will see that the user's status changes from yellow to red, and so on, other users will Identify the general situation of the user's funds.

Similarly, the user's own funds are also displayed by color on the interface. If it is red, it means insufficient funds, and you should recharge in time. After recharging, the system will change its status from red to yellow or green according to the recharging status.

Through this personal account identification device, the system, on the one hand, provides reference for users when choosing information transactions, and can also see the general situation of user account funds during the transaction process, ensuring the normal flow of user funds. On the other hand, users can also know their financial status in time and recharge in time.

Fig. 10A illustrates the detailed flow of the user wealth index (value index) device of the IP interactive TV center.

In this device, it mainly involves two parts, one part is on the client side, and the other part is on the main control server side. The following two parts are described in detail:

For the main control server, there is a database table (personnetinfo) for recording the user IP wealth index (value index). For details about this table, refer to the description in FIG. 11 .

In the accounting module of this system, when the system calculates the user's income and information expenses, the master control server will generate a record or update an old record in the table, that is, the system first locates the user's ID number Records, query in the IP wealth index (value index) table, if a record is found, read the values of the f_userpaynum, f_userrecvnum and f_usersumnum fields of the record, and then update the values of the f_userpaynum or f_userrecvnum fields according to whether the user is expenditure or income , that is, use the queried value to add the newly generated value, and finally, update the f_usersumnum field, which is also to use the queried value to add the newly generated value.

If there is no record for the user (located by ID number) in the table, the system will insert a new record and fill the f_userpaynum or f_userrecvnum and f_usersumnum fields with the newly generated values.

For the user side, he sends a control command to the main control server to query the user's IP wealth index (value index) and is responsible for displaying it. At this time, the user needs to provide the main control server with the ID number of the user to be queried. .

After receiving the user's command, the main control server enters the background through its own control and scheduling, and then queries the user IP wealth index (value index) record table of the main control server (the ID number provided by the user is used to locate the record). After querying the wealth index (value index) of the specified user, the master control server returns the information to the user.

When the client program receives the return information from the master control server, it will display the information, and the user can know the IP wealth index (or value index) of the user just inquired, regardless of other specific information of the user, and can Determine its wealth and value on the Internet, and choose to exchange and share information with it accordingly, so as to increase its wealth and value on the Internet faster.

Fig. 10B illustrates the processing flow of the IP interactive television center user's online business index device on the main control server, and the interaction process between the main control server and users is similar to that of the wealth index device, please refer to the description in Fig. 10A.

When the main control server receives the user's request command, it first analyzes the user's command, then enters the server background scheduling process, calculates the online business index and returns it to the user. Specifically, it is processed according to the following process:

The master control server queries the user's personal online wealth index from the user's wealth index record table, including:

● The user’s income interaction index;

● The user spending interaction index;

● The total interaction index of the user;

Among them, the ID number of the user to be queried is used to locate the records in the table.

After inquiring these information, the main control server also needs to inquire out the total accumulative time (number of days) of the user from registration in the system to the present, that is, first inquire out the registration time from the user registration data table, and then take out the system Time, the difference between the two is the accumulated time (number of days) of the user in the system.

After the main control server obtains these values, it can perform the calculation of the IP interactive TV personal network provider:

● Personal income online business index: income interaction index/cumulative time;

● Personal expenditure online business index: expenditure interaction index/cumulative time;

● Personal total online business index: total interaction index/cumulative time;

The main control server can calculate these values separately, and then return to the user, and the user records and displays it locally.

The above mainly explains the processing flow of the online merchant on the main control server side, and the interaction process with the user is shown in FIG. 10A . The processing (or flow) of the two is similar.

In this way, through the IP interactive TV personal wealth index (value index) and the IP interactive TV network business index, it shows the user's activity level on the Internet more accurately, and reflects the growth of the user's personal wealth and value on the Internet.

Fig. 11 illustrates the detailed structure of the wealth index (value index) table (personnetinfo) of the IP interactive TV center database. The user's wealth index (value index) information on the Internet is recorded in the master control server database user IP wealth index (value index) basic information table (personnetinfo), as follows:

personnetinfo table structure/field description

field name field description Remark f_index Used to record user login information record index number none f_userid Used to record user identification ID number primary key f_userpaynum Used to record user spending wealth index (value index) none f_userrecvnum Used to record user income wealth index (value index) none f_usersumnum Used to record the user's total wealth index (value index) none f_flag Used to record user logo information none

In this database table, each field needs to be recorded. Of course, the final display is the total wealth index (value index) of the user. Therefore, the f_userpaynum field and the f_userrecvnum field can be empty, and the user’s total is recorded in the f_usersumnum field. Wealth index (value index) will do. In this way, when the user queries, the value of the f_usersumnum field can be obtained.

In the database table, the billing and payment part of the program automatically fills or updates the corresponding records of the table according to the calculation results:

● The f_index field is the record index number that is automatically incremented by the database when a new record is inserted;

● The f_userid field is filled with the user's personal unique ID in this system;

● The f_userpaynum field is used to record the wealth index (value index) value added when the user pays the fee in this system;

● The f_userrecvnum field is used to record the wealth index (value index) value added when the user earns the tariff in this system;

● The f_usersumnum field is used to record the value of the wealth index (value index) added by the user’s expenditure/income in this system (the value is equal to the sum of the f_userpaynum and f_userrecvnum fields);

● f_flag is used to mark user information so that the program can identify user personal information during processing;

The description of the structure/fields of the personnetinfo table is as follows:

● f_index: int;

● f_userid: int;

● f_userpaynum: int;

● f_userrecvnum: int;

● f_usersumnum: int;

● f_flag: char(1).

Figure 12 illustrates the IP interactive television center database (meetinginfo).

The detailed information of the IP interactive TV center created by the user is recorded in the IP interactive TV center program information table (meetinginfo) of the main control server database, as follows:
