BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows the system configuration of an embodiment of the present invention. In FIG. 1, the service provider creates a video 51 by the video creation system, and
Related information is registered in the database center 300. At this time, guidance information for accessing a predetermined database of the database center 300 is recorded in a video in a multiplexed manner, and a guidance telop or the like that calls attention is put in the video.

The navigation video 100 has a function of decoding guide information recorded by being multiplexed with the video signal, and has a function of connecting to the database center 300 via the network 200 and communicating. The guide information includes a telephone number or network ID for database access, a database ID, a video ID, and the like.

The usage of this system differs between the service provider and the user. The service provider prepares a database that provides detailed information in response to the video user's request to introduce products and services in an easy-to-understand and concise manner, and sends a database guide telop to the video to alert the user and to access the database. Guidance information including a telephone number, network ID, database server ID, etc. is multiplexed and recorded in synchronization with the video. The user can play the video in the navigation video, and if the detailed information is needed, switch the navigation video to the communication mode and automatically connect to the prepared database to obtain the detailed information.

As a method for multiplex recording of guidance information in synchronization with a video signal, an analog method using a vertical blanking period of an analog video signal and a method of digitizing a video signal and transmitting a part of a data string to guide information data transmission are used. There is a digital method used.

In the case of the analog system, specifically, Showa 6
Method of multiplexing guide information instead of character transmission of character multiplex broadcasting specified by Ordinance No. 77 of the Ministry of Posts and Telecommunications issued on October 15, 2000, and No. 2 specified by Ordinance No. 51 of the Ministry of Posts and Telecommunications issued on July 4, 1995 Generation EDTV (Normal EDTV-II, commentary article Nikkei Electronics no. 638, p. 140, 1995.
Part of the identification signal multiplexed on the two 22nd and 285th vertical blanking scan lines in (6.19) is used. For example, if undefined bits 15 and 16 of the EDTV-II system are used, 4 bits can be used in one frame, so that a data signal of 120 bits per second can be multiplexed. A vertical blanking interval (VBI) data broadcasting system can also be used.

In the case of the digital system, specifically, 1994
January-December, 2004, "Basic Technology of Digital Television Broadcasting" (vol.48, N
o. 1, pp. 57-64, vol. 49, no. 2,
pp. 16-170 etc.), a part of the seventh, sixth and fifth layers of the layer model for digital broadcasting (see FIG. 5 and p. 165, p. 61 of the same magazine) is used. That is, the seventh layer that defines the application defines the operation of providing guidance information of the present invention and the sixth layer that defines the presentation.
The guide information is actually encoded in the layer, and in the fifth layer that defines the session, the guide information is multiplexed in the data string in addition to the image and audio information so that the data can be identified, distributed, and grouped.

As guidance information, a guidance telop or the like is inserted in the video and is multiplexed in synchronization with this. The amount of information assigned to one channel in digital television broadcasting is about 3-6 Mb /
s. Of these, if 0.1% of data is secured for interactive operations other than the image / sound specified in the application layer, data transmission of 3-6 kb / s is possible per second. Since the program lasts at least 15 seconds, data of 4500 to 9000 bits can be transmitted during this period, and guidance information including an error correction function can be sufficiently transmitted.

The user uses the remote controller 109 to perform normal video operations on the navigation video 100, and also controls information transmitted to and received from the database center 300 via the network 200. In the communication mode, the guide information can be used to auto-dial or log in to the database center, and information communication is performed with the database center 300 via the network 200. The network can be a local area network LAN, a public telephone line, a two-way cable network such as ISDN and CATV, and a wireless network such as mobile radio. The database is connected not only directly to the LAN but also via personal computer communication, the Internet, etc. can do.

The appearance of the navigation video 100 is shown in FIG.
Shown in 2, the same parts as those in FIG. 1 are designated by the same reference numerals, and detailed description thereof will be omitted. Window 11
3 does not open during normal reception, but displays guide information, user information, and communication information with the database center in the communication mode. It is also possible to switch the entire screen to the communication mode instead of the window. 100 is roughly divided into video playback and display, guidance information decoding, and communication control. Of these, the decoding and display of the guide information is performed by a teletext receiver or an EDTV-II receiver in the case of an analog system, and by a digital system in the case of a digital system, a digital radio broadcast television receiver using satellite or terrestrial, a CATV It can be used by modifying a digital cable TV receiver that uses an optical cable.

A video tape, a video disk, a CD-ROM or the like is inserted into the video insertion port 114. In addition,
If the video is taken out from the VOD server via the network and played back by VOD (video on demand) without using the video package as described above, the video insertion port is not necessary. In this case, as shown in FIG. 14, instead of the video 51, the VOD server 301
Is connected to a network, and an STB (set top box) for VOD can be improved and used as a navigation device on the terminal side.

The circuit configuration of the navigation video 100 is shown in FIG. In FIG. 3, the following circuits are common bus 11
Connected to 0.

The CPU 101 is a read only memory (RO
M) executes the overall control of the device according to the system program stored in 102. Information transmitted and received between the circuits connected to the common bus 110 is read by the CPU 101 from the circuit on the transmission side and written in the circuit on the reception side. Further, as will be described later, the CPU 101 operates as the communication control circuit of the present invention.

The ROM 102 stores in advance a system program to be executed by the CPU 101, as well as data used in the execution of this program, for example, a character code string used as a display message and a font conversion table for converting the character code into a character pattern. doing. The random access memory (RAM) 103 is input data,
The output data and the calculation result of the CPU 101 are temporarily stored.

The nondestructive memory 104 stores and stores user information relating to the present invention. The user information includes a user ID (identification code), name, address, telephone number and the like. In addition to these, gender, date of birth, nationality, occupation, blood type, etc. can be considered, but these are properly used according to the purpose of use. The user ID information is used for collation with the password input by the user and for transmission to the communication destination. The nondestructive memory 104 is selected from nondestructive semiconductor memories (programmable memory, flash memory, ferroelectric memory, etc.), IC cards, magnetic cards, optical cards, magnetic disks, optical disks, etc., according to the application. When the removable card is used, the user information can be stored separately from the navigation video, which is convenient not only for home navigation video but also for friend's house or hotel navigation video. Furthermore, if a credit card is used, there is no need to enter a payment account number, and convenience is further improved.

The input / output interface (I / O) 105 transfers the operation instruction from the CPU 101 to the modem 111. Further, the CPU 101 receives an instruction to switch between the modem 111 and the handset 150. In this embodiment, as the modem 111, a modem having an automatic call function for calling the database center according to an instruction of a telephone number from the outside (in this case, the CPU 101) is used.

The video processing apparatus main body 106 decodes a video signal to display a television image, and also has a function of decoding guidance information multiplexed in the video signal and the decoded guidance information and the database center 300 via the network 200. It has a function of visually displaying the received information. It should be noted that it is convenient to add a broadcast TV receiving function to the main body of the video processing device so that a television signal can be received, recorded and reproduced.

The operation panel 107 includes a power switch, a volume switch, a ten-key pad, and a control key.
Equipped on top. The numeric keypad is used for selecting a video in the normal mode (in the case of a randomly accessible video such as a DVD), and is used as an input circuit of the present invention for inputting numerical information in the communication mode. The control key consists of execute, stop, cancel, etc.
It is used to stop and cancel the numeric keypad input.

The receiving circuit 108 is the remote controller 1
The input signal transmitted by wireless from 09 is received. The remote controller 109 has an input switch similar to the operation panel 107, and wirelessly transmits an input signal.

The circuit configuration of the video processor main body 106 is shown in FIG. 4 for the analog system and the digital system, respectively.
It shows in (a) and FIG.4 (b).

In FIGS. 4 (a) and 4 (b), the same functions are indicated by the same numbers, and the duplicated description will be omitted.

In FIG. 4A, the analog-recorded video 51a is reproduced by the analog video reproducer 52a, the image and the sound are demodulated by the demodulator 53a, and output from the display 56 and the speaker 57. Decoder 11
2a decodes the guidance information multiplexed in the video signal. On the other hand, the video 51 recorded digitally in FIG.
b is reproduced in the digital video reproducer 52b.
The reproduced digital video signal is decoded by the video decoder 53b, converted into an analog video signal by the D / A converter 49, and combined with the window image stored in the video memory 54 under the control of the display controller 55. Displayed on the display 56.

The decoders 112a and 112b decode the guidance information multiplexed in the analog video signal and the digital video signal, respectively.

In the case of analog, since the guide information is multiplexed in the vertical blanking period, it is decoded in the same manner as the decoder of the teletext signal or the data broadcast signal. In the digital case, the guide information is inserted in a predetermined part of the bit stream, and therefore, it is decoded in the same manner as the decoder of the digital television signal.

The video memory 54 has a CPU 101 shown in FIG.
Is accessible. The guidance information decoded by the decoder 112 is temporarily stored in the RAM 103 according to an instruction from the CPU 101, and thereafter, together with the information received from the database center 300, in the form of a character pattern, the CPU 10
By writing 1 into the video memory 54, it becomes possible to display character information on the window display screen of the display 56.

FIG. 13 shows a video processing device for reproducing a video by improving the STB by the VOD method.
In the figure, the same functions as those in FIG. The digital bit stream of the video obtained through the network 200 is the network interface 52c.
The waveform is shaped by and is decoded by the video decoder 53c. The multiplexed guide signal is decoded by the decoder 112c. These video decoder 53c and decoder 112c
The basic function of can be the same as that of FIG.

In such a configuration, when the normal mode is instructed from the operation panel 107 or the remote controller 109 of FIG. 2, the CPU 101 sets the normal mode, and the operation panel 107 or the remote controller 10 is set.
The operation instruction input from the No. 9 is transferred to the video processing device 106. When the CPU 101 receives a communication mode instruction, the communication mode is set, and information is exchanged between the navigation video 100 and the database center 300 according to the protocol procedure shown in FIG.

That is, first, the user side activates the two-way communication program to call the center 300. The center that receives the call collates the user ID and password and responds with permission / non-permission. If permission is granted, information is exchanged, and when finished, the center sends an end signal and the call is disconnected.

The system configuration of the database center 300 is shown in FIG. When connected to the navigation television 100, the sub computer 304 connected to the network 200 performs the following information processing together with the host computer 303, and the response information determined from the information processing result is transmitted to the navigation television 100 in response. In the host computer, ID information corresponding to guide information transmitted in a multiplexed manner with a television signal is registered in advance.
The host computer 303 receives the ID information from the sub computer 304 via the path 305, and executes a process of collating the ID information and detecting a specific ID information in the received ID information. The keyboard 301 inputs information to the host computer 303. CRT
A (display device) 302 visually displays information instructed by the host computer.

Various methods are available for configuring the network and the database center, such as connecting a database server to personal computer communication or the Internet, using a local area LAN, using an ISDN line, and using a telephone company's database service. Various forms are possible. It is also possible to connect to the database center via a two-way CATV.

Information transmission processing performed in the system described above will be described with reference to the flowcharts of FIGS. 7 and 8. The flowchart of FIG. 7 is the CPU 10 of FIG.
1 shows the contents of the system program executed by No. 1. This system program is written in a program language executable by the CPU 101 and stored in the ROM 102. The flowchart of FIG. 8 is based on the database center 3 of FIG.
00 shows the contents of the system program executed by the sub computer 304. This system program is also written in the programming language and stored in the sub computer 304. 7 and 8 are functionally represented for convenience of description.

As an example of the communication mode, a case where the user watches the product guide video and the user applies for shopping at the database center 300 of the selling source will be described. The normal mode is initialized when the power is turned on.

The user uses the operation panel 107 or the remote controller 109 to select a video. As a result, the designated video image is displayed on the display 56. When creating a video, insert a telop that prompts activation of the communication mode in advance in the video image,
In synchronization with the video, guidance information including the video ID, the telephone number of the database center, the database server ID, etc. is multiplexed and recorded in the video signal.

Seeing this telop, the user operates the operation panel 107 or the remote controller 109 to instruct the communication mode by operating, for example, an execution key which is a specific control key. When the CPU 101 detects that the communication mode is instructed by determining the numerical value designated by the key (YES determination in S10 of FIG. 7), it executes the bidirectional communication program after S20. The CPU 101 temporarily takes out the guidance information decoded by the decoder 112 (112a, 112b or 112c) to the RAM 103, converts it into a character pattern, writes it in the video memory 54, and controls the display controller 55 to display one of the images. A window is opened in the section (113 in FIG. 2) and a guidance information message is displayed on the display 56 (S20 in FIG. 7). The message can be superimposed on the video signal without opening the window. An example of the screen at this time is shown in D10 of FIG. The window and the superimposition may be used together.

Next, the CPU 101 reads a message (code string) prompting the user information from the ROM 102, converts it into a character pattern, and then writes it in the video memory 54 to display the message on the display 56 (S30 in FIG. 7). ). When the user sees the display of this message, he or she inputs his or her password using the ten keys of the operation panel 107 or the remote controller 109 (S40 in FIG. 7). An example of the screen at this time is shown in D20 of FIG. In the figure, □ indicates the numeric keypad input.

The user operates the execution key of the operation panel 107 or the remote controller 109 to give an instruction to start communication. The CPU 101 connects the modem 111 to the I / O 105
Issue a calling command via. As a result, after the modem 111 connects to the network by the auto dial function,
The CPU 101 calls the sub computer 304 of the database center 300 by the auto login function,
User information and guidance information are transmitted (S50 in FIG. 7).
After that, the system 101 waits for a response from the sub computer 304 (loop processing of S60 of FIG. 7).

On the other hand, when the sub computer 304 of the database center receives the user ID and password in response to the call from the navigation video 100,
It is verified whether or not these are registered in advance, and if the result of the verification indicates that the user ID is not registered or the passwords do not match, the navigation video 100 displays a disapproval signal indicating disapproval of subsequent communication. To send a response to (Fig. 7
S200 → S225).

If the result of the collation shows that the user ID has been registered, the sub computer 304 registers the database ID and the program ID in the host computer 303 and makes it collate whether or not the one prepared in advance by the guide video. . If there is a disagreement as a result of collation, a communication disapproval signal is transmitted to the navigation video 100 (S210 → S22 in FIG. 8).
0 → S225). If the collation is correct, the sub computer 304 performs predetermined communication with the host computer 303 and the navigation video 100 (S2 in FIG. 8).
20 → S230 → S240). When the predetermined communication is completed, an end signal is transmitted and the control procedure of FIG. 8 is completed (FIG. 8).
S250).

Returning to FIG. 7, the navigation video 100
When the CPU 101 receives the permission / non-permission signal from the sub computer 304 via the modem 111 (S in FIG. 7).
60), if this signal indicates that communication is not permitted, the procedure is S1.
Modem 1 to disconnect the public line 200.
11 is instructed (S70 → S100 in FIG. 7). When the received signal indicates permission, the CPU 101 executes communication with the sub computer and writes the communication information sent to the video memory 54 (FIGS. 4A, 4B and 13) to display 56. Displayed on the operation panel 107
Alternatively, the numerical information input from the ten-key pad of the remote controller 109, for example, the designation of the product or color, the designation of the payment method, and the credit number are transmitted to the sub computer 304 via the modem 111 (S70 → S80 in FIG. 7).
The CPU 101 also displays the input numerical information on the display 56 of the television receiver body 106 via the video memory 54. If you make a mistake using the numeric keypad, use the cancel key to correct it. An example of the communication information screen is shown in D30 of FIG. In the figure, □ indicates the numeric keypad input. It is safe to use encrypted communication for the password and credit number communication described above.

Hereinafter, the CPU 101 is the sub computer 3
Until the end signal is received from 04, it operates as the communication control circuit of the present invention to control the transmission / reception of information. In addition, the information received from the sub computer 304 is displayed on the display 56.
Is displayed on the screen (loop processing of S80 to S90 in FIG. 7). Upon receiving the end signal, the CPU 101 shuts off the public line and ends this procedure (S100). Although not shown in the figure, a series of communication controls can be terminated at any time by operating stop control keys provided on the operation panel and the remote controller.

In this embodiment, the case where the sub computer of the database center is directly accessed from the public line has been described, but it is more general to access the database center via the Internet or the personal computer communication service. In this case, the sub computer 304 in FIG. 5 may be replaced with a gateway processor for the Internet or personal computer communication service, the host computer 303 with a database server, and the bus 305 with a network.

2, FIG. 3 and FIG. 4 (a), FIG. 4 (b),
The navigation video shown in FIG. 13 is intended for a dedicated device, but if there is a video playback function and a personal computer with a built-in modem, the navigation video function described above with the program application software of the personal computer can be easily realized. For example, in FIG. 3, the CPU 101 and the ROM 1
02, RAM 103, non-destructive memory 104, I / O 10
5, the modem 111 and the operation panel 107 can be replaced with a personal computer with a built-in modem and program software. Also, these functions can be replaced by a game machine with a built-in modem. Furthermore, if a personal computer with a built-in modem with a video playback function or a game machine with a built-in modem with a video playback function is used, in addition to the above, the video player 52a, the video demodulator 53a, the speaker 57, and the video memory 54 of FIG. The display controller 55 and the display 56 can be replaced. The same applies to the digital system shown in FIG. However, in this case, the guide information multiplexed in the video signal is decoded to
A mechanism that U can control is required. In addition, it is also possible to configure a control device having the functions of decoding guidance information, inputting information, a modem, and communication control separately from the main body of the video processing device, and connecting and using this control device as a television adapter. .

FIG. 10 shows another embodiment of the navigation video 100. The communication information in FIG. 9 shows an example of two-way communication with the database center, but in order to implement a fine-grained service according to the user's preference and desire, the guide information from the database center should be richer. There is a need to. At this time, it is often difficult to understand only by the screen display. Therefore, in FIG. 10, in addition to displaying the communication information from the database center on the screen, a function of outputting by voice is also provided. The communication information from the database center is sent from the data bus 110 to the voice synthesizer 58, converted into a voice signal, and synthesized with the television voice by the voice controller 59, and then the speaker 57.
Is output as voice. The voice controller can switch to one side by a switch function in addition to the method of mixing voices.

11 and 12 show another embodiment of communication control. 7 and 8 show the case where communication is not established when the user ID is not registered in the database center in advance. However, in order to deal with various applications using television broadcasting, it is necessary to allow the user to register the user's ID by a simple method even for the first time user. FIG. 11 and FIG. 12 are examples of communication control of the navigation television and the database center to which the ID registration function for the first user is added, respectively.

In FIG. 7, FIG. 7 and FIG. 11 and FIG. 8 and FIG.
2 corresponds, and the same function is indicated by the same number.
In FIG. 11, the user terminal sets the communication mode, and when the guide information is stored and displayed, it is determined whether or not the initial registration is performed (S21 in FIG. 11). This can be left to the user to choose or the system can determine automatically. If it is not the initial registration, it is the same as in FIG. 7. For initial registration, issue a call request to the network and follow the initial registration guide provided by the network.
Initial registration is performed (S61 → S22 in FIG. 11), and then the normal communication mode is entered. Corresponding to this, the communication control on the side of the database center is the same as in FIG. 8 except for the initial registration, as shown in FIG. When the user makes a request for initial registration, the initial registration program S202 runs at the same time as the online registration of personal computer communication to prompt the user for registration.
When this is completed, the user is asked to confirm the user ID and password, and if OK, the normal communication mode is entered. I
The D / password confirmation program confirms credit information such as a credit number in order to avoid registration of an unauthorized user (S203 in FIG. 12).

Although the present embodiment shows the case of product introduction, the navigation video 100 can also be used for training instructions, teaching materials, educational guidance, electronic magazines and the like.

[0064]

As described above, according to the present invention,
Users will be able to easily realize two-way communication with the database center guided by the video telop. On the other hand, the service providing side can efficiently obtain the user information by bidirectional communication with the user.

The navigation video for carrying out such bidirectional communication can be provided inexpensively, easily and safely by using the technology of a personal computer or a video game.
