Description

A system and method for realizing customization of TV program content

technical field

The invention relates to TV program customization, in particular to a system and method for realizing TV program content customization.

Background technique

As we all know, the broadcasting of TV programs is currently completely controlled by TV stations, and TV viewers only have the right to choose whether to watch or not. That is to say, the TV station decides the broadcasting time and program content of the TV program, and the TV viewer can only watch the determined program content at the determined broadcasting time, and the program content preferred by the TV viewer can only be watched at the broadcasting time of the TV station.

In order to enable viewers to watch their favorite program content at any time, the existing scheme mainly combines a personal video recorder (PVR) with a television set to record their favorite program content for themselves to watch at any time. In this way, viewers must provide PVR equipment, such as buying a set-top box (STB) integrated with a PVR, or buying a TV set with an integrated PVR, or buying a separate PVR to be connected to the TV set. In terms of storage media, tapes, CDs, hard drives or computers are generally used. As shown in FIG. 1, all recording operations are performed locally on the TV set, such as inside a home.

The specific recording operation process is: the audience watches the program content broadcast by the TV station in real time, and when they watch their favorite TV program and want to record it, they operate the PVR device to record the current broadcast content. During the recording process, they need Monitor recording conditions, such as whether to pause or end a recording. During the recording process or after the recording is over, the recorded TV programs can be stored in the PVR device’s own memory, external hard disk, computer or tape drive and other storage devices, and the recorded TV programs can also be edited through the computer or Carved into a disc. Wherein, the program content signal recorded by the PVR device is input from the local, which may be a TV device or a CATV Cable.

It can be seen from the above scheme that the recording scheme of the prior art has the following problems:

1. In order to record TV programs, viewers need to purchase expensive PVR equipment, and the storage space of the PVR equipment is limited. In order to solve the problem of storage space, the above-mentioned scheme proposes the method of using storage devices such as personal computers or external hard disks to store the recorded TV programs. For this reason, users also need to possess personal computers or external hard disks, which will increase the cost of users. cost. Nevertheless, the local storage space of a personal computer is generally only on the order of Gbyte, such as 40G, 80G, and 160G. Users often have to delete other favorite TV programs in order to save new TV program content, and cannot really achieve the same program. Repeated viewing many times. Therefore, neither the built-in memory in the PVR device nor the external storage device can achieve mass storage.

2. The above-mentioned recording process requires the audience to be at the scene of the TV program broadcast. If the audience is not present, the recording cannot be performed, because the recording process requires the audience to monitor the recording situation on the spot, and manual intervention is required to start, pause or end the recording.

3. The above-mentioned recording process is only real-time recording, that is, the recording of the currently playing TV program is performed while watching TV, but only relying on the current PVR device itself still cannot make an appointment to record TV programs and record programs of multiple TV channels at the same time.

Although some users may reserve and record TV programs through computers at present, if the scheduled recording is controlled through a personal computer, it is not only necessary to add corresponding control software to the personal computer, but also to modify the PVR device, that is, to add a personal recognition device to the PVR device. The functional module of the control signal sent by the computer, or the development of new products with the above-mentioned functions, and requires the TV, personal computer and PVR equipment to be always on, so that TV programs of any time period can be recorded. It is conceivable that for a single family, this method will cause a great waste of resources, and if each family uses the above method to record TV programs, it will cause a greater waste of data. In addition, since the compression coding in the recording process of TV program signals has high requirements on computer resources, especially the computer CPU, due to the influence of computer performance, it is still impossible to use a personal computer to simultaneously record multiple sets of TV programs.

Wherein, the mobile terminal 25 or the personal computer 24 can be used as a TV program customization request sending device, which is mainly used to generate a TV program customization request according to the TV program information input by the user, and send it to the streaming media data center 23 through the Internet 20 . In this embodiment, the television set 21 and the set-top box 22 can also be used as a TV program customization request sending device. The streaming media data center 23 is mainly used to receive and record the received TV program according to the customization request sent by the user through the above-mentioned TV program customization request sending device, and receive and transmit the content of the recorded TV program through the Internet according to the received user playback request. 20 is sent to the set-top box 22 and played by the TV set 21. In this embodiment, the set-top box 22 is used as the playback control terminal for playing personalized TV program content, and a personal computer may also be used as the playback control terminal.

The television set 21 belongs to audio-video equipment, and the audio-video equipment is equipment capable of playing TV programs, and of course other audio-video equipment can also be used. The set-top box 22 is used in conjunction with the TV set 21. Therefore, the set-top box 22 can be regarded as a user terminal, which is mainly used to provide an interactive channel between the TV set 21 and the streaming media data center 23, and provide an interface for user information interaction. The set-top box 22 is connected to the TV 21 through an audio/video (A/V) signal line. Generally, a browser is embedded in the set-top box 22, and the browser is similar to the IE browser. After the set-top box 22 and the TV set 21 are powered on, the browser in the set-top box will send a request to the streaming media data center 23 to read the TV program list. An electronic program menu (EPG) is included in the streaming media data center 23, and the EPG is similar to a WEB server. The process that the set-top box 22 reads the TV program is exactly the process that the browser initiates a request to the EPG and loads the content of the TV program. This process is similar to the process of using IE to browse the web. Here, the set-top box 22 needs to be able to support MPEG-1 or MPEG-2 or MPEG-4 or WMV format. In addition, the system provided by the present invention may further include a remote control device 211 for inputting TV program information, and the remote control device 211 is connected to the set-top box 22 in a wireless manner. By operating the remote control device 211, operations such as TV program list preview, TV program customization, customized TV program query, modification and deletion, TV program viewing/pause, fast forward/fast rewind, etc. can be performed.

In order to ensure the playback quality of audio and video signals, a broadband network is generally used to transmit recorded TV programs. Therefore, broadband access is required on the user side, which can be local area network (LAN) access, CABLE MODEM access or broadband access methods such as ADSL. What the embodiment shown in Fig. 2 adopts is the broadband access mode of ADSL, and wherein, between the modem (MODEM) 27 of ADSL and the set-top box 22, connect by network cable, like this, set-top box 22 is connected to the central office equipment of Internet 20 by MODEM 27 For example, on a DSL line access module (DSLAM) 28 .

In order to enable the streaming media data center 23 to obtain and regularly update the TV program list, the streaming media data center 23 is also connected to the TV station program list server 26 that provides TV program list information in the broadcasting network through the Internet. The connection between the streaming media data center 23 and the program list server 26 of the TV station can be in various ways, such as message mode or relatively simple text mode. In addition, when the mobile terminal surfs the Internet or sends a short message to make a TV program subscription and send a custom request, a mobile network 29 that supports mobile terminal Internet access and short message services, such as a CDMA-1X or GPRS network, is required. The docking of the streaming media data center 23 with the mobile network 23 that supports mobile terminal Internet access services and short message services is to use the streaming media data center as a value-added service provider (VASP) to connect with mobile operators through the SMPP protocol.

As shown in FIG. 2 , the streaming media data center 23 includes: a media center server (Media&Centerserver) 230 and an encoder (Encoder) 232 . Among them, the media center server 230 mainly notifies the encoder 232 to record the TV program according to the customization request of the user, receives and stores the content of the TV program recorded by the encoder 232, and provides the stored TV program to the user when receiving the playback request from the user. . The encoder 232 is used to record the received TV program signal in an encoded form according to the instruction of the media center server 230, for example, encode the TV program content reserved by the user into a format such as MPEG-1/2/4, and send to the media center server 230. Since the encoder 232 performing the recording work of the present invention completes hardware-level signal acquisition and encoding and compression through a dedicated hardware chip, multiple sets of TV programs can be recorded at the same time. The television program signal received by the encoder 232 may be a radio frequency signal or an audio-visual (A/V) signal. The signal receiving method can be wired such as a radio frequency line or an A/V signal line, or wireless satellite receiving, such as using a satellite antenna.

The encoder 232 is connected to the media center server 230 through a network cable, and the information transmission between the two is mainly realized through the internal interface between the two. The internal interface may include: a signaling interface for transmitting recording instructions, a streaming interface for transmitting TV program signals, and a storage interface for storing recorded TV programs in the form of files to the media center server. The streaming interface is a real-time streaming interface through which a TV program is encoded and transmitted, for example, a data stream of a TV program signal may be carried and transmitted through a real-time streaming protocol (RTSP). The storage interface is generally a Fast Ethernet (FE) interface, a Gigabit Ethernet (GE) interface, or a Fiber Channel (FC) interface. Wherein, the stream interface and the storage interface are optional, that is to say, the TV program recorded by the encoder 232 can be transmitted to the media center server 230 through the stream interface or the storage interface.

The media center server 230 also provides various external interfaces connected with external systems. The external interfaces mainly include: program synchronous interface, WAP interface, short message interface, Portal interface for HTTP access, and management interface of the whole system, etc. The synchronous interface of the program list is a message channel for fetching the program list from the program list server to the media center server. The WAP interface is a message channel for users who customize program content online through the mobile terminal WAP page. The short message interface is a message channel for users who customize program content through short messages. The Portal interface accessed by HTTP is a message channel for personal computer users to customize program content.

The working principle of the system of the present invention will be described in detail below.

The media center server 230 periodically sends a program list request to the TV station program list server 26 through the program list synchronization interface, so as to extract the latest current TV program list. After receiving the program list request sent by the media center server 230, the TV station program list server 26 compares the current latest TV program list with the saved TV program list sent to the media center server 230 last time, and judges whether the TV program list content has Change, if there is a change, then the latest TV program list is sent to the media center server 230, and the latest TV program list information sent is saved as a new TV program list sent last time; The server 230 returns that the program list has not changed. After receiving the latest program list, the media center server 230 updates the content of the program list stored therein.

The user can submit the TV program customization request to the media center server in various ways through the TV program customization request sending device. For example, the user browses the Portal web page for customizing TV programs provided by the media center server 230 through a personal computer 24 or a mobile terminal 25 capable of surfing the Internet, selects a TV program to be customized, and then submits a customization request. After the media center server 230 receives the TV program customization request submitted by the user, the one-way encoder 232 issues a TV program recording command according to the customization request and the current TV program. After receiving the recording command, the encoder 232 encodes and records the received TV program signal according to the recording command, and sends the recorded TV program content to the media center server 230 through the stream interface or the storage interface. The media center server 230 stores received TV program content.

In this embodiment, the user can select a customized TV program to watch through the user information interaction interface provided by the set-top box 22 . After the user selects a certain TV program, the set-top box 22 submits a request for playing the TV program to the media center server 230 . When the media center server 230 receives the user's TV program play request, it reads out the corresponding TV program content from its own memory according to the program item in the play request, and transmits it to the set-top box 22 of the specific user through the Internet 20 and passes it through the TV set 21. to play.

Fig. 3 is the composition structural diagram of streaming media data center in an embodiment of the present invention, and wherein, the media center server 230 that streaming media data center comprises comprises: portal (Portal) component 31, media management unit (MMU, MediaManagementUnit) component 32, Edge media service unit (HMS) component 33, storage unit 34 and other components.

Wherein, the process in which the Portal component 31 redirects the play request to the HMS component 33 can be accomplished by using a prior art redirection mechanism. In this embodiment, the background database for storing user information and customized task information is located on the Portal component 31 and can be accessed by other components.

The function of the MMU part 32 is to perform media management, mainly as an enabling part, to receive the customization request forwarded by the Portal part 31, to process the user's TV program customization task contained in the customization request, and to issue instructions to the encoder 232 to control encoding The recording actions of the device 232, such as start recording, stop recording, etc., and report the completion of the custom task. The function of the HMS part 33 is to receive the play request of the user requesting to consume its customized TV program content redirected by the Portal part 31, obtain the required TV content from the storage unit 34 according to the received play request, and use the TV content data flow The mode is provided to the set-top box 22, and it is played on the TV set 21, and its function is similar to VOD-SERVER. After the TV program is played, the HMS component 33 will modify the current playable times in the background database, and notify the MMU component to delete the played TV program content from the storage unit 34 according to the current playable times.

The storage unit 34 is mainly used for storing recorded TV program content. In this embodiment, the storage unit 34 is a storage area network (SAN). The SAN includes multiple disks, each with a capacity of several hundred GByte, and the SAN can be expanded smoothly, such as expanding the SAN from 1TByte to 10TByte to 100TByte, etc., where 1Tbyte=1000Gbyte. Therefore, SAN can be regarded as a storage factory. In terms of physical connection, the above components can all be connected to an Ethernet switch or a hub.

Based on the above system, the whole flow of the present invention to realize the customized recording of TV program content is shown in Figure 4, including the following steps:

Step 41, the streaming media data center regularly obtains TV program information from the TV station program system according to a preset timer, so as to obtain the latest TV program list. The above-mentioned process is a synchronization process of the TV program list.

Step 42: When the streaming media data center receives the TV program customization request sent by the user, it records and stores the TV program content according to the current TV program list and other information and the received customization request.

Step 43. When the streaming media data center receives the TV program play request sent by the user, it searches for the corresponding TV program content from its own storage according to the received play request, sends it to the audio and video equipment through the network and plays it. The above playing process is the process of consuming the customized TV program by the user.

In step 41 of the above solution, the process of regularly obtaining the latest TV program list is the TV program list synchronization process. The TV program list synchronization process refers to synchronizing the content of the TV program list of each channel broadcast in the local TV network from the radio and television network operator to the The process of the media center server in the TV program content customization system of the present invention. The synchronizing process of the TV program list will be described in detail below.

Step 52: After receiving the program list request, the TV station program list server compares the current latest TV program list with the last TV program list sent to the MMU component.

The TV station program list server saves the TV program list sent to the MMU component last time in the background database, and after sending the latest TV program list each time, updates the last TV program list sent to the database with the latest TV program list sent this time. TV listings for MMU components.

Steps 53-55: Judging whether there is any change in the content of the program list, if there is a change, then send the latest TV program list to the MMU unit, otherwise reply to the MMU unit that the TV program list has not changed.

Step 56: After the MMU part in the media center server receives the information returned by the TV station program list server, if it finds that the latest TV program list is received, then update the TV program list content in the background database of the Portal part; If there is no change in the program list, the MMU component does not do any processing.

The process of synchronizing the TV program list can also be: when the latest TV program list contained in itself changes, the TV station program list server actively sends the latest TV program list to the MMU component in the media center server, and the streaming media data center receives the TV program list from the TV station. After the latest TV program list sent by the program list server, update the currently saved TV program list with the latest TV program list. In addition, the TV station program list server periodically maintains heartbeat messages with the MMU component in the media center server. The heartbeat message is used to ensure that the MMU component can know that the communication between the MMU component itself and the program list server of the TV station is normal.

In step 42, the user can send a television program customization request to the streaming media data center in the following three ways: through Portal customization, through STB customization and through short message customization. The above three methods are described respectively below.

1. Customization through Portal: This method is mainly to customize the TV program items required by the user by visiting the user customization page provided by the Portal component. Therefore, the premise of using this customization method is that the user needs to have a TV program that can access the Internet The terminal can be an ordinary personal computer (PC) terminal connected to the Internet, or a mobile terminal connected to a CDMA-1X or GPRS network. The specific process of customizing through a common PC terminal is shown in Figure 6, including the following steps:

Step 61: the user accesses the user's TV program customization page provided by the Portal component in the media center server from the PC terminal through a browser, such as:

http://portal.cctv.com.cn/pc/customization.jsp.

Here, the action of the user inputting http://portal.cctv.com.cn/pc/customization.jsp is a user request.

Step 62: After the Portal component in the media center server receives the user's request, it reads the background database, takes out the information data such as the content of the TV program list therein, arranges them, and transmits them to the user's PC terminal.

Step 63: The user browses the latest TV program content through the user's TV program customization page, selects the TV program item he wants to customize by clicking to generate a customization request, and submits it to the media center server.

Step 64: After receiving the customization request from the user, the Portal component in the media center server adds it to the task processing queue of the MMU component and waits for the MMU component to process it. Here, it is assumed that the customization request initiated by the above user is legal.

Step 65: The Portal component in the media center server returns to the user the processing result of the system receiving the user customization request to notify the user whether the customization is successful or not. Watch then.

The process of user customization through a mobile terminal that supports WAP access to the Internet is basically the same as the above-mentioned process, the only difference is that the former uses a PC terminal to connect to the Portal web page through the Internet, and the latter uses a mobile terminal to access the Internet through a mobile terminal that supports WAP. A network, such as Monternet, is connected to the Portal web page. In terms of customized page display, user customized process and background processing process, the two are similar, and may even be completely the same. Therefore, the process of customizing through the mobile terminal will not be repeated here.

2. Customized by STB:

The basic flow of STB customization is shown in Figure 7, including the following steps:

Step 71: Power on the TV set and the STB on the user side, and the browser of the STB sends a request for reading TV program list information to the Portal component in the media center server through the network.

Among them, after the TV and the STB are powered on, the STB will first load the EPG frame. The EPG frame is the page provided by the EPG, which is similar to the WEB page provided by the WEB SERVER, but does not contain the content in the page. The electronic program guide information provided by the EPG is displayed in the EPG frame only after the EPG in the component initiates a request to read the program guide.

Step 72: The Portal component in the media center server reads the TV program list information from the background database, returns it to the STB browser through the network, and displays it to the user through the user-side TV.

Step 73: The user selects the TV program to be customized from the TV program list information through the remote control of the STB, confirms and submits the customized TV program, generates a customization request and sends it to the media center server.

Step 74: After receiving the user customization request, the Portal component in the media center server adds the user customization request as a customization task to the task processing queue of the MMU component for processing. Here, it is assumed that the above customization request is legal.

Step 75: The Portal component in the media center server notifies the user of the processing result of the system receiving the user's customization request, for example, it may return to the user: "The Eight Steps of the Dragon" you customized has taken effect, please watch it then.

3. Customization via short message: Customization via short message is generally applicable to temporary customization. A precondition for adopting this customizing method is that the user knows the broadcasting time and broadcasting channel of the TV program that needs to be customized. For example, if CCTV1 broadcasts the TV series "Conquest" during the time period from 20:30 to 22:10 in the evening, then the user can send a short message with the following content: "2004122820302210 CCTV1" to a specific short message service number, such as short message service The number is 8888. The meaning of the short message is: to customize the content of the program broadcast on CCTV1 from 20:30 to 22:10 on December 28, 2004. Or, the user also can send the short message of following content: 200412282030 100 CCTV1, the implication of this short message is: customize the program content broadcast on CCTV1 within 100 minutes from 20:30 on December 28, 2004.

The detailed process of short message customization flow is described below, as shown in Figure 8, suppose program customization short message service number is 8888, and the operator of the system of the present invention has applied to become VASP, specifically comprises the following steps:

Step 81: The user edits the short message according to the specified format, and sends it to the short message service number 8888.

Step 82: After the short message service center recognizes that the destination of the short message sent to the short message service number 8888 is the Portal component in the media center server, the short message is transferred to the Portal component in the media center server through the SMPP protocol.

Step 83: After receiving the short message customization request from the user, the Portal component in the media center server analyzes the customization request and adds it to the task processing queue for processing. Here, it is assumed that the above customization request is legal.

Step 84: The Portal component in the media center server sends a short message of successful customization to the user through the SMPP protocol.

The TV program customized by the above customization method can be customized according to the content of the TV program, or can be customized according to the time period of the TV program. Wherein, the customization according to the content of the TV program refers to the customization based on the content as the index key, which is also called item customization. The customization according to the time period of the TV program refers to the customization based on the time period as the index key. Specifically, the customized page displays information such as the channel number, program content, and broadcast time to the user in a way similar to the TV program forecast of the TV newspaper. For example, the channel number is CCTV1, the TV program is Lucky 52, broadcast The time is 20:00～21:00. If the user specifies to customize the program content of CCTV1: Lucky 52 when customizing the TV program, then this method is to customize according to the TV program content. In contrast, if the user specifies the time period 20:00-21:00 to customize CCTV1 when customizing the TV program, then this method is to customize according to the time period of the TV program, although the result of the latter customization is also lucky 52 .

In the solution described above, after the Portal component in the media center server receives the program customization request message, the specific operation of the customization request is shown in Figure 9, which mainly includes the following steps:

Step 91: The Portal component in the media center server submits the received program customization request message as a customization task to the MMU component for processing.

Steps 92-94: After the MMU component in the media center server receives the customized task, it judges whether the customized task is legal. If the customized task is not legal, it reports a customized task error to the user through the Portal component; if the customized task is legal, then continue to execute the steps 94.

Among them, the conditions for judging whether the customization task is legal include: judging whether the user who sent the customization request is a registered user, whether the format of the customization request is correct, whether the customized TV program in the customization request exists in the program list, and whether the customization request is from the same user In the same request sent, whether the broadcast time of the customized TV program requested in the customization request has passed, when the above conditions are met, the customization task is legal, otherwise the customization task is not legal.

Steps 94-95: The MMU component in the media center server adds the legal custom task to the task processing queue, and activates the custom task at a specific time, that is, the MMU component sends a recording instruction to the encoder to notify the encoder to encode and record a specific TV program . For example, if the user customizes a program at 20:00, then this customized task will be activated at 20:00. Among them, the task processing queue is used to store custom tasks that can be recorded.

Step 96: After the encoder receives the recording instruction sent by the MMU component in the media center server, it encodes and records the TV program required by the customized task. After the customized task is completed, the encoder sends a task completion report to the MMU component.

Step 97: After the MMU part in the media center server receives the task completion report, the task completion situation is written into the background database of the Portal part, such as the file name and path corresponding to the customized program, and the system customizes the task for each user Generate the URL in the respective MyPortal page and update the personal portal (MyPortal) for this user.

In the above process, different users may need to record the same TV program. In order to save storage space and prevent repeated recording, the present invention provides a better processing method. Detailed description will be given below.

Since the customization method provided by the present invention includes the method of customizing according to the content of the TV program and the method of customizing according to the time period of the TV program, there will be the following two repeated situations: one is the customization request initiated according to the content of the TV program The other is the repetition of the content of the customized request initiated according to the time period. These two possible repetitions of custom tasks can be handled in the following ways:

When the customization request is a customization request initiated according to the content of a TV program, the streaming media data center judges whether the content of the customization task is the same as the content of the customization task currently in the task processing queue, and if they are the same, the customization task will not be added to the task processing queue, if not the same, then add the custom task to the task processing queue.

When the custom request is a custom request initiated according to the time period, the streaming media data center judges whether the custom task time period overlaps with the custom task time period currently in the task processing queue, and if not, adds the custom task to In the task processing queue, if there is a repetition, judge whether it is a complete repetition. If it is a complete repetition, the custom task will not be added to the task processing queue. If it is not a complete repetition, the custom task will be different from the time period it has Completely repeated custom tasks are merged to generate a custom task containing the sum of each time period set, which is added to the task processing queue.

For example, for the first case: assuming that two users A and B customize TV programs, assuming that user A first initiates a request for customized content content1, the system analyzes whether the user request is legal according to the flow shown in Figure 9, assuming the If the request is legal, the MMU component checks whether content1 is duplicated in the background database. Assuming there is no duplicate, the customized task is put into the task processing queue to be processed, and the "successful subscription" information is returned to the user through the Portal component.

Afterwards, user B also initiates a request for custom content content1. Similarly, the system analyzes the received user request to determine whether it is legitimate. Repeat, at this time the system does not put this customized task in the task processing queue for processing, but still returns the information of "successful subscription" to the user through the Portal component.

For the second case, assume that user A first subscribes to the content in the T1-T2 time period, and the system accepts the customization request according to the above processing flow and returns the successful subscription information; then user B initiates subscription to the content in the T3-T4 time period, if the request is legal , the system will return a successful subscription message to the user, but the system needs to further determine whether to put this task into the task processing queue, which needs to be processed according to the repeated situation at the time end. At this time, the system processes as follows:

Due to consideration of time segment repetition, the situation that T4 is less than or equal to T1, or T3 is greater than or equal to T2 is not considered. If T1≤T3 and T2≥T4, then this task will not be placed in the task processing queue, but the item subscribed by user B will be added to the background database; if T1 is greater than T3 or T2 is less than T4, then the task requested by user B will not be placed Task processing queue, but to modify the task customized by user A in the task processing queue, modify the start time T1 to Max{T1, T3}; modify the end time T2 to Max{T2, T4}. In this way, after the encoder receives the recording instruction, it starts to record the TV program content between the time period: Max{T1, T3} to Max{T2, T4}. Among them, Max is the maximum value operation.

Although the contents of the two user customization requests are merged, the system will not lose the original request data sent by the user, and will still record the user customization information according to the user's original request data. That is to say, the system will still mark the respective start time and end time of the user-customized tasks in the database. For example, the time period of user A is still T1-T2; the time period of user B is still T3-T4.

Afterwards, if a third user C requests to record the content of T5~T6, the processing flow of the system is the same as above: it is still necessary to modify the start time and end time in the above task processing queue, and the start time is changed to: Max{Max {T1, T3}, T5}, the end time is changed to: Max{Max{T2, T4}, T6}. There will be follow-up users in the future, and the processing flow is the same as above.

Since different user customization requests with overlapping time periods will result in merging or modification of the customization task, a TV program content file will be saved corresponding to the execution result of the customization task. As described above, since the system will record the start and stop time of each user separately, when the system generates the URL in the respective MyPortal page for each user custom task, it will read the respective start and stop time from the database. time and add it to the URL. In this way, when the user clicks on the TV program customized by himself through the remote control device, the parameters in the play request messages sent by different users are different.

For example: user A and user B both customize the TV program content of CCTV1, but the customized start and end time periods are T1~T2 and T3~T4 respectively, assuming T1<T3<T2<T4, assuming the combined customized task recording results Save it as filel.wmv.

When playing a TV program, the playback request uploaded by user A's set-top box can be:

rtsp://media/path/play?user=A&channel=cctv1&start=T1&end=T2

The playback request uploaded by user B's set-top box can be:

rtsp://media/path/play?user=B&channel=cctv1&start=T3&end=T4

From the files read by the HMS component, the two set-top boxes read the same file filel.wmv, but when the HMS component plays to user A, it reads from the 0 time offset of the file filel.wmv. When the HMS component plays to user B, it reads from the offset of {T3-T1} of the file filel.wmv and plays to user B.

In addition, if the user needs to cancel the TV program customization request that he has already sent, he can also use the above three ways of sending the customization request, but the command is to cancel the customization task request. After the Portal component forwards the request to cancel the customization task to the MMU component, the MMU component analyzes the records in the database to judge and distinguish two situations:

One case is that the customized task accepted by the system is the only user task of this user. At this time, after the MMU component receives the request to cancel the customized task, it judges whether the customized task to be canceled in the canceled customized task request belongs to the customized task in the task processing queue. , if yes, then delete the custom task, and return the custom task cancellation success to the user; if not, the MMU component compares the custom task to be canceled in the custom task request with the currently completed custom task in the background database of the Portal component , to determine whether the custom task to be canceled in the custom task request is a completed custom task, if yes, return to the user that the custom task has been completed and cannot be canceled; otherwise, return to the user without canceling.

Another situation is that the custom task accepted by the system is not the only user task of this user. At this time, the MMU component needs to query the database. If the custom task has been executed, it will return to the user that the task has been completed and cannot be canceled; otherwise, change the task Process related custom tasks in the queue. The logic of changing related custom tasks is similar to the processing logic of custom tasks when multiple users have overlapping time periods, and will not be repeated here. Similarly, after the change recognizes that the tasks in the processing queue are completed, the cancellation success is returned to the user.

In addition to canceling the sent custom tasks, users can also query the content of TV programs they have subscribed to. When querying customized TV program tasks, the command sent by the user is to query the current customized task. After the MMU component receives the query command, it needs to query the unprocessed task processing queue and the completed customized task database, and then return the query result to the user. If it is to query the currently recorded TV programs, it only needs to query the completed customized task database, and then return the query result to the user. Users can inquire online through PC terminals and mobile terminals, and can also inquire by sending short messages. The specific process is similar to the way of sending a custom request, the only difference is that the operation command sent is different.

In step 43 of FIG. 4 , the specific process of the user consuming the customized program content is shown in FIG. 10 , including the following steps:

Step 101: After the television set on the user side and the STB are powered on, the STB reads the data of the information interface used by the user in the background database of the Portal component in the media center server through the network for customizing and playing the TV program, and converts the electronic program list and other information are displayed on the TV.

Step 102: The user selects the MyPortal option in the information interaction interface. After the MyPortal option is selected, the Portal component in the media center server verifies the user information after receiving the request. If the user information verification is successful, then reads the user-customized information in the background database. The TV program entry information is displayed on the MyPortal interface of the TV. If the user has not customized any TV programs, the displayed content is empty; if the user information verification is unsuccessful, the illegal user is displayed.

Step 103: The user selects and submits his own customized program content from the customized TV program item information listed in the MyPortal interface, for example, selects "Discovery), generates a playback request, and sends it to the media center server.

Step 104: After the Portal component in the media center server receives the user's playback request, it verifies the user information again. After the user information is verified, the Portal component sends a redirection message to the user's set-top box. The redirection message contains the protocol for accessing the HMS component , the IP address of the HMS component, the TV program content information, and the encrypted string of user authentication information, etc., wherein the protocol for accessing the HMS component is generally the RTSP protocol.

Step 105: After receiving the redirection message, the user's STB automatically initiates a redirected play request including the TV program content information to the HMS component through a corresponding access protocol, such as the RTSP protocol.

Step 106: After receiving the redirected play request, the HMS component interacts with the STB on the user end through RTSP protocol information, and then starts sending the TV program content data stream to the STB of the user, that is, plays the TV program content data stream to the user through streaming. Recorded TV program content, and start billing. Wherein, whether to charge and how to charge are optional, and can be performed according to operator rules. The RTSP protocol information interaction refers to the internal information interaction stipulated in the RTSP protocol specification, including many complex interactions, which will not be repeated here.

Considering the situation that the user plays the same TV program multiple times, after the TV program requested to be played is finished, it is necessary to operate according to the number of times set by the user during customization, modify the user's customization information in the database, and decrement the number of users by one. For the predetermined number of times of playing, judge whether the current number of times of playing is zero. If it is zero, the HMS component will notify the MMU component to delete the TV program content; otherwise, the decrement result will be saved. For example, if the user selects N times of playback during customization, the HMS component will modify the record in the database from N to N-1 after one playback is completed; when N-1=0, the HMS component will notify the MMU component to delete The content of the television program.

Or, it is also possible to determine whether the TV program content needs to be deleted in the following manner: accumulating the current playing times of the played TV program, judging whether the cumulative result of the playing times is the same as the user's predetermined playing times, and if they are the same, then deleting the TV program content; If they are not the same, save the currently accumulated playback times as the cumulative base after the next playback ends.

The above process of modifying the playing times to determine whether to delete the played TV program content is based on the premise that a certain TV program content is only a TV program customized by a user. For the situation that multiple users customize a TV program content at the same time, whether to delete the TV program content needs to analyze whether all users have watched the TV program content, if all users who customize the TV program content in the system database have watched If the TV program content is passed, that is, the current play times of all subscribers in the subscription database for this TV program content are all 0, then the HMS component will notify the MMU component to delete the file corresponding to the TV program content; otherwise, the file will be kept until all All of the users have already watched this TV show content.

The above playing process is completed through audio and video equipment such as set-top boxes and televisions, and of course, it can also be played through a personal computer terminal. If the future mobile network transmission rate meets the requirements, of course, mobile terminals can also be used to realize the playback of personalized TV programs.

It can be seen from the above solution that the system and method for customizing TV program content provided by the present invention can record personal preferred TV programs when the user cannot watch TV and no one is monitoring, so as to realize TV program recording anytime and anywhere. Moreover, the system and method provided by the present invention can not only reserve recording in advance, but also record TV programs of multiple TV channels at the same time. In addition, since the storage method provided by the solution of the present invention can realize resource sharing and centralized deployment, users can realize mass storage without considering the limitation of storage space.

Moreover, in the early stage of development of the TV program content customization service provided by the present invention, only a single streaming media data center node can be used to meet business needs, but with the growth of business volume, the service node can not only be limited to the streaming media data center , and the HMS components of the streaming media data center can also be deployed in a distributed manner to support large business volumes.

In a word, the above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in this within the scope of protection of the invention.
