FIG. 7 shows an example of a configuration in which a receiver is cut out of a multi-view broadcast system for realizing a multi-view automatic switching broadcast service.

The receiver is a receiving unit 1301, a screen control unit 13
06, tuner 701, program guide information decoder 702,
It comprises a user request receiving section 703, a multi-view automatic switching control section 704, and an AV decoder 705. Receiver 13
01 and the function of the screen control unit 1303 are the same as those of the conventional example. The tuner 701 outputs the multi-view automatic switching table to the multi-view automatic switching control unit 704 in addition to the function of the tuner 1302 of the conventional example. The program guide information decoder 702 is a conventional program guide information decoder 13.
In addition to the function 03, the user can select the multi-view automatic switching pattern as indicated by 411 by the multi-view automatic switching information of the individual program information 305 of the program information table on the electronic program guide. When the user selects a multi-view automatic switching pattern from the electronic program guide using a remote controller (not shown), multi-view automatic switching pattern selection information is input to the program guide information decoder 702 via the user request control unit 703. Program guide information decoder 7 receiving multi-view automatic switching pattern selection information
02 outputs a view switching request to the multi-view automatic switching control unit 704 together with a pattern identifier selected to perform view switching according to the corresponding pattern. The multi-view automatic switching control unit 704 that has received the view switching request
A multi-view automatic switching table matching the corresponding pattern is found from all the multi-view automatic switching tables received from the tuner 701, and the corresponding video / audio component information is decoded so as to decode the video / audio components described in the corresponding multi-view automatic switching table. Output to the AV decoder 705. Upon receiving the AV TS packet stream and the video / audio component information of the selected destination view, the AV decoder 705 extracts the video / audio component of the selected destination view from the AV TS packet stream, decodes it, and sends it to the screen control unit 1306. Output.
Thereafter, the multi-view automatic switching control unit 704 monitors the change of the corresponding multi-view automatic switching table, and every time there is a change, decodes the selected video / audio component information so as to decode the changed video / audio component.
Output to the decoder 705.

An example of the operation of the receiver when the multi-view automatic switching broadcasting service is selected using the processing flows of FIGS. 5 and 9 will be described. First, the user request control unit 703 receives an electronic program guide display request from the user (step 901).

Upon receiving the electronic program guide display request, user request control section 703 issues a program guide information display request to program guide information decoder 702 (step 902). Upon receiving the program guide information display request, the program guide information decoder 702 decodes the program guide information stream acquired from the tuner 701, generates an electronic program guide, and outputs it to the screen control unit 1306 (step 903).

The screen control unit 1306 displays the decoded electronic program guide on a screen (not shown). 5 examples of electronic program guide
09 (step 904).

When the user selects a multi-view automatic switching pattern on the electronic program guide, the user request control unit 703 receives a multi-view automatic switching pattern selection request together with a switching pattern identifier. For example, it is assumed that “pattern 1” has been selected (step 905).

The user request control unit 703 outputs the switching pattern identifier to the multi-view automatic switching control unit 704 (Step 906).

Upon receiving the switching pattern identifier, the multi-view automatic switching control unit 704 receives the multi-view automatic switching table stream 507 from the tuner, and acquires a multi-view automatic switching table having the corresponding switching pattern (step 907).

When the multi-view automatic switching control unit 704 acquires the multi-view automatic switching table, the AV decoder 705 decodes the video component and the audio component described in the multi-view automatic switching table at the switching time described in the multi-view automatic switching table. To send a decode instruction. For example, assuming that the multi-view automatic switching table 511 is received in step 907 and the current time is 18:01, the current video component is the main video and the audio component is audio 1 according to the switching time of the multi-view automatic switching table 511. , And the AV decoder 705 decodes the information of the main video stream 501 and the audio 1 stream 504.
(Step 908).

AV decoder 705 receiving the decoding instruction
Acquires the designated main video stream and one audio stream from the tuner 701, and decodes and outputs the video and audio to a television (not shown) via the screen control unit 1306 (step 909).

A multi-view automatic switching control unit 704
Checks whether the version number of the corresponding multi-view automatic switching table is changed (step 910).
When the multi-view automatic switching control unit 704 receives the multi-view automatic switching table whose version number has been changed until the program ends, the multi-view automatic switching control unit 704 repeats the same processing as steps 908 and 909 (step 911).

For example, when the multi-view automatic switching table 512 in which the video component is changed to the multi-view video 1 is received in step 805, the current time becomes the corresponding switching time of 19:30:20, or If 19:30:20 has passed by the time the automatic view switching table 512 is received, the video stream to be decoded is switched to the multi-view video 1 stream 502. Similarly, the receiver that has received the multi-view automatic switching table 513 in which the version number, the video component, and the audio component have been changed in step 805 has a current time of 20:00:
In the case where it becomes 40 or when 20:00:40 has passed when the multi-view automatic switching table 513 is received, the video stream and the audio stream to be decoded are switched to the multi-view video 2 stream 503 and the audio 2 stream 505.

A plurality of switching times 601 as shown in FIG.
Receives the scheduled multi-view automatic switching table, and decodes the corresponding video component and audio component at the designated switching time.

Note that a recording device (not shown) records all the video / audio components to be multi-viewed and the multi-view automatic switching table when recording a program to be subjected to the multi-view automatic switching broadcast service, so that the recording device can reproduce the program. Similarly, the user can enjoy the multi-view automatic switching broadcasting service.

Note that the data transmitting unit and the receiver can be a program on a recording medium for executing the processing of each device and each unit described above.

As described above, when performing multi-view broadcasting, multi-view broadcasting can only be effected for the number of channels prepared, but multi-view video / audio is automatically transmitted to the receiver by the multi-view automatic switching table. By performing the switching, it is possible to broadcast the switching pattern of the multi-view video / audio as if it were the number of channels or more. Thereby, for example, it is possible to produce an effect for the same program by a plurality of directors.
Further, the viewer can enjoy his / her program by selecting his / her favorite effect from a plurality of effects.
