Abstract

PURPOSE:To constitute the content of a program to be desired by a receiver side by selecting and outputting information to be displayed based on program identification information from plural sets of video program information and outputting the selected information. CONSTITUTION:A broadcast station 2 is provided with a main program transmitter 31 and slave program transmitters 22, 23 sending a slave program. The transmission programs are sent through a same broadcast band as program multiplex information by a multiplex transmitter 24. Moreover, the transmitter 24 multiplexes and sends the program identification information to discriminate the content of the multiplexed program as control information. A television receiver 1 uses a tuner section 5 to select and receive a broadcast from the broadcast stations 2, 3. Then a program multiplex detection section 11 identifies it that the information indicates the multiplexed main and slave broadcasts and sends the identification information to an output control section 7 from an identification information transmission section 12. When a viewer makes switching command, since a signal extraction section 6 selects a reproduced program based on the result of detection of a program switching command detection section 13 and the detection section 11, the receiver 1 edits the program to be a desired program constitution.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a one-way communication television broadcasting system, and in particular, a system that multiplexes and simultaneously broadcasts a plurality of programs and allows viewers to make independent decisions. It is possible to combine programs based on
The present invention relates to a television program multiplex broadcast system suitable for efficiently broadcasting information corresponding to the wishes of viewers.

[Prior Art 1] Currently, there are various communication devices and communication systems aimed at communicating intentions between remote locations.

In particular, image information is the most effective information for communicating intentions because it visually discloses information, and various visual image information transmission techniques have been developed in order to communicate intentions more efficiently.

Image communication for transmitting such images is achieved by electrically converting visual information, transmitting it, and reproducing it as a visible image on the receiving side.

Television broadcasting systems are currently the most widely used image information communication technology.

A television broadcasting system is a system in which a television receiver receives video program information transmitted from a television broadcasting station having program production equipment and transmission equipment, and displays moving images.

The following methods are available for providing such moving image information in accordance with the individual wishes of an unspecified number of viewers.

For example, there are a plurality of television broadcasting stations that provide programs, each of which transmits video program information through its own television channel. Then, the television receiver selects and outputs the desired channel from each channel.

Audio multiplex tuner and its effective use J (lIJ80
As described in pp. 214-226 of 2013, published by Seibundo Shinkosha, a method for multiplexing multiple audio signals onto the audio channels of a television channel is currently in practical use. Bilingual broadcasting gives viewers greater freedom in programming.

For example, the main carrier wave with the main signal of Japanese broadcasting,
Frequency modulation (FM:
Frequency Modulation) subcarriers, and amplitude modulation (AM
A composite signal consisting of the above three signals is broadcast from a broadcasting station as a TV audio multiplex broadcast using an audio carrier wave next to a TV video carrier wave. Then, the television receiver that receives this television audio multiplex broadcast has a demodulation section (
adapter) to separate the composite signal through a filter, etc. Furthermore, the main signal of the Japanese broadcast and the sub-signal of the foreign language broadcast are demodulated by an FM detector and output as sound via a power amplifier, speaker, etc. In addition, the control signal is demodulated by an AM detector and used to drive a changeover switch (for example, switching from a foreign language to Japanese) or a display circuit for the type of broadcast (two-language broadcast or stereo broadcast). In this manner, current television receivers allow viewers to change the desired program by switching television channels, and to change the audio within the same program on the same television channel.

On the other hand, in order to use this television receiver to provide information that more flexibly responds to the wishes of viewers, C A P T is used to change programs through two-way communication.

TV (cable television broadcasting), etc.

In CAPTA IN, for example, Japanese Patent Application Laid-Open No. 1-3168
As stated in Publication No. 69, broadcasting stations display program guides on television receivers in each home via telephone lines, and while viewing the program guides, viewers use their telephones as terminals to enter the identification number of the desired program. Enter. Then, based on the identification number input by the viewer, the broadcasting station changes the program to the one desired by the viewer and broadcasts it.

The advantage of CAPTAIN broadcasting is that, for example, by using a television receiver, viewers can receive information that appeals to their sense of sight and hearing, and that viewers can Being able to choose the services you want to receive.

On the other hand, CATV uses a bandwidth that can accommodate dozens of channels by communicating high-frequency (several hundred MHz) video data and accompanying audio over wires, making it possible to multiplex television programs. becomes.

Furthermore, for example, "Nikkei Electronics 1989 4-17J (
There are those described in PP134-135 of Nikkei BP, 1989). That is, a screen with icons associated with moving images stored on a video disc is displayed on the computer display, and based on the viewer's click on the icon, the desired moving image is displayed on the television receiver. be. In this way, the viewer not only accepts or accepts a given program sequence unilaterally;
This allows viewers to actively participate in watching the video.

[Problems to be Solved by the Invention] Changing video program information using two-way communication in the prior art is suitable for individual viewers to search for advertisements or search in databases. When a viewer selects a program (Sanibis), it takes time to change the program, and the information intended by the broadcasting station cannot be transmitted efficiently.

Furthermore, in conventional television broadcasting, which is one-way broadcast communication, it is not possible to freely change the content or organization of a single program to suit the preferences of viewers.
For this reason, the program, ie, information, configured by the broadcasting station is broadcast to all viewers with the same content.

For example, in a professional baseball night game broadcast, if the game does not end within a predetermined time, some viewers may prefer to continue broadcasting the night game rather than the next scheduled program, and some viewers may prefer to continue broadcasting the night game rather than watching the next scheduled program. The viewer is in a state where he/she wishes to watch the next program as scheduled.

In this case, in order to accommodate the wishes of both parties, the broadcasting station must:
Each broadcast must be sent using separate television channels, which creates a heavy burden on the broadcasting station in terms of equipment and program operation management, and generally cannot be handled by a single broadcasting station. Ta.

Also, depending on the content structure of news programs such as politics and science, viewers who have sufficient prior knowledge of the information being broadcast may find it boring; For viewers without sufficient prior knowledge, the program becomes incomprehensible, and for regular viewers, the program becomes unappealing.

In addition, the display selection method of moving images using a computer is as follows.
It is necessary to associate moving images stored on a video disk with icons on a computer display screen in advance, and it is not possible to select a variety of television broadcast programs in real time.

As described above, conventional television broadcasting systems have been unable to efficiently provide programs that flexibly respond to the wishes of viewers with different tastes.

The purpose of the present invention is to solve the problems of the prior art, and to improve efficiency by editing the content of programs broadcast on television using one-way communication into the configuration desired by viewers on the television receiver side. It is an object of the present invention to provide a television program multiplex broadcast receiving device that enables transmission of good information.

[Means to solve the problem]

In order to achieve the above object, the television program multiplex broadcasting system of the present invention (1) causes a broadcast station device to multiplex a plurality of video program information and program identification information for identifying these video program information in the same broadcast band. a multiplex transmission control unit that transmits the multiplexed video program information, and a program multiplex detection unit that detects, based on program identification information, that the received program information is multiplexed video program information; an identification information sending unit that sends identification information indicating that the received program information is program multiplex information for image display based on the detection result; and a display program from a viewer based on the identification information displayed in the image. a program switching instruction detection section that detects a switching instruction; and an output that selects the output of program information to be displayed as an image from among a plurality of video program information based on the detection results of the program switching instruction detection section and the detection results of the program multiplexing detection section. The present invention is characterized in that it is provided with a program selection control section.

(2) In the television program multiplex broadcast receiving system described in (1) above, the television receiving device includes a program information storage section for storing and reproducing received program information, and preparation for reproduction operation of the program information storage section. Storage device control that sends stored program identification information indicating completion for image display, and controls storage/playback operations of the program information storage unit based on the detection results of the program switching instruction detection unit and the detection results of the program multiplexing detection unit. It is characterized by having a section.

(3) In the television program multiplex broadcasting system described in (2) above, a plurality of programs are broadcast by a plurality of storage device control units based on a procedure arbitrarily set and registered in advance by a viewer in a television receiving device. 6. [Function] In the present invention, the television broadcasting station is , multiplex broadcasts not only audio but also multiple video program information on one television channel (broadcast band).

That is, the video program information that is constantly broadcast is the main program, and the video program information that is multiplexed on the main program is the sub-program.

During program multiplex broadcasting, an identification indicating that program multiplex broadcasting is in progress is displayed on the main program or subsidiary program screen. From this identification display, the viewer can, for example, understand the existence of the subsidiary program and change the display to the subsidiary program. In this way, viewers can e.g.
Information related to the main program can be found in more detail in the sub-programs. Conversely, if the subsidiary program is not selected, there will be no waste in viewing unnecessary information.

Furthermore, after viewing the subsidiary program, the reception screen automatically switches to the main program, allowing the viewer to continue viewing the main program.

Furthermore, at the same time as the display is changed from the main program to the sub-program according to the viewer's instruction, the main program is stored in a video device or the like.

As a result, the main program at the time of broadcasting of the subsidiary program can also be provided to the viewers later.

Further, a plurality of storage devices such as video devices are connected, and each of them is driven and controlled in correspondence with a plurality of multiplexed video program information. This also makes it possible to store the main program and subsidiary programs that are broadcast while the stored program is being played back and displayed.

Furthermore, by allowing the viewer to arbitrarily set and register the drive control procedures for each storage device in advance, the viewer can freely select between the main program and the subsidiary program. Can be edited.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1st [! 1 is a block diagram showing a first embodiment of the configuration of a television program multiplex broadcast system according to the present invention; FIG.

The television program multiplex broadcast system of this embodiment includes broadcast stations 2 and 3 that broadcast program multiplex broadcasts in which a main program, a subsidiary program, and program identification information (control signals) for identifying each program are multiplexed; The television receiver 1 selects and displays either the main program or the sub-program from the multiplexed programs based on the viewer's operation, and is connected by a transmission line 4 made of a wired cable.

The broadcasting station 2 broadcasts the programs transmitted from the main program transmitting device 21 for transmitting the main program, the subsidiary program transmitting devices 22 to 23 for transmitting the subsidiary programs, the main program transmitting device 112) and the subsidiary program transmitting devices 22 to 23 at the same time. The broadcasting station 3 is constructed of a multiplex transmitting device 24 that multiplexes information in a band and transmits it as program multiplex information.The broadcasting station 3 also has a similar configuration. Furthermore, when multiplexing a main program and a subsidiary program, the multiplexing device 24 multiplexes program identification information for determining the content of the multiplexed program into the program multiplexing information as a control signal and transmits the multiplexed information.

The television receiver l includes a tuner section 5 that selects and receives television broadcasts from broadcasting stations 2.3, and a television broadcast (including multiplexed programs) received by the tuner section 5, which is converted into video and sound. a signal extraction unit 6 that separates and reproduces each frequency band in which it exists and extracts it as images and sounds;
An output control section 7 outputs the reproduced video and sound to the video/audio output section 8; and a program selection control section according to the present invention that selects a program to be reproduced by the signal extraction section 6 and displayed on the video/audio output section 8. It consists of a section 10. Note that the viewer's operations related to the reception operation are performed via the remote control 9.

The program selection control unit 10 detects, based on the control signal extracted by the signal extraction unit 6, that the program information selected and received by the tuner unit 5 is a multiplex of a main program and a subsidiary program. A multiplex detection unit 11 , an identification information sending unit 12 that sends identification information indicating that the received program information is program multiplex information to the output control unit 7 , and switching of the viewer's display program sent via the remote control 9 A program switching instruction detecting section 13 that detects an instruction, and a signal extracting section 6 based on the detection result of the program switching instruction detecting section 13 and the detection result of the program multiplexing detecting section 11.
The output program selection control section 14 selects the main program or the sub-program played back and sends it to the output control section 7.

Although wired cables are used for the five transmission lines 4 in this embodiment, wireless broadcasting may also be used.

Furthermore, a frequency division method is adopted as a multiplexing method for simultaneously transmitting multiple programs.

With this configuration, the television program multiplex broadcasting system of this embodiment provides programs that meet the diverse needs of viewers.

The operation of the television program multiplex broadcasting system of this embodiment according to the present invention will be described below.

For example, if broadcasting station 2 broadcasts a night game broadcast of a professional baseball game and the game does not end within the scheduled time, broadcasting station 2 multiplexes the program and broadcasts it. Based on the progress (program program, program schedule), the main program from the main program transmitting device 21 is, for example, a weather forecast or a music program that follows it. Further, a night game broadcast of a professional baseball game is set as a subsidiary program from the subsidiary program transmitting device 22. Then, in the multiplex transmission bag [24], the signals are multiplexed together with the control signal and broadcast as a program multiplex broadcast.

The television receiver 1 outputs a weather forecast program to the video/audio output unit 8 when the broadcast of a night game of a professional baseball game ends. At the same time, based on the control signal extracted by the signal extracting section 6, the program multiplexing detecting section 11 detects that a program multiplexing is being broadcast. Then, the identification information sending unit 12 sends identification information indicating that the program is being multiplexed to the output control unit 7, and displays it on the screen of the video and audio output unit 8 displaying the weather forecast.

Here, if the viewer wants to continue watching the professional baseball night game broadcast instead of the weather forecast, the program switching instruction detection unit 13 inputs a program switching instruction via the remote control 9. Based on the detection, the output program selection control section 14 selects and extracts the subsidiary program information, that is, the broadcast of a professional baseball night game, from the signal reproduced by the signal extraction section 6, and sends it to the output control section 7. do. Then, via the output control section 7, the video/audio output section 8 outputs the broadcast of a night game of professional baseball.

In this way, viewers can watch night game broadcasts of professional baseball games.

Furthermore, when the night game broadcast of professional baseball, which is a subsidiary program, ends, the program multiplex detection section 11 detects the end of the program multiplex broadcast via the signal extraction section 6. Then, based on the detection, the output program selection control section 14 sends the signal of the main program reproduced by the signal extraction section 6 to the output control section 7, and returns the program output by the video/audio output section 8 to the main program.

FIG. 2 is a flowchart showing an embodiment of the operation of the television receiver shown in FIG. 1 according to the present invention.

When the power is turned on (step 201) and the tuner section receives a broadcast from one broadcast station (step 202), based on the signal reproduction result of the signal extraction section (step 203),
The program multiplex detection unit determines whether the program is multiplexed broadcast (step 204).

If it is a program multiplex broadcast, the identification information sending unit transmits information indicating that the program multiplex broadcast is being received, and outputs it to the video and audio output unit (step 205). Then, the program switching instruction detection section determines the instruction from the viewer (step 206) and detects whether the viewer's selection is a main program or a subsidiary program (step 207).

If the instruction from the viewer is to select the main program, the output program selection control section selects the output of the main program reproduced by the signal extraction section (step 208), and then outputs the video and audio via the output control section. (Step 209).

If the program multiplex detection unit detects the end of the subsidiary program, that is, the end of the program multiplex broadcast while the main program is being output (step 2
10) Stop sending information from the identification information sending unit during program multiplex broadcast reception (step 211).

Then, when the power is turned off (step 212), reception of the broadcast ends.

In step 207, if the viewer selects a subsidiary program, the output program selection control section selects the subsidiary program reproduced by the signal extraction section (step 213), and outputs it to the video and audio output section via the output control section (step 213). Step 214) 6 When the program multiplex detection unit detects the end of the subsidiary program (Step 215), the output program selection control unit switches the output to the video and audio output unit to the main program reproduced by the signal extraction unit ( Step 216) Then, the process proceeds to step 211, where the transmission of the information being received from the job-specific information transmission unit is stopped.

Further, in step 204, if the broadcast being received is not a program multiplex broadcast, the program reproduced by the signal extraction section is output to the video/audio output section (step 217).

In this way, the viewer can freely select the main program and the subsidiary program.

Next, a storage device for recording programs, such as a VTR (Video), is attached to the television receiver shown in FIG.
This section describes a system that connects a tape recorder, video tape recorder, etc., and edits multiple programs broadcast from a broadcasting station into programs that better match the wishes of viewers.

FIG. 3 is a block diagram showing a second embodiment of the present invention of a television program multiplex broadcasting system to which the present invention is applied.

The television program multiplex broadcasting system according to the embodiment of Mizuei 2 includes a television receiver 30 in place of the television receiver l in the television program multiplex broadcasting system according to the first embodiment shown in FIG. It is something that

The television receiver 30 has a plurality of (7) VTs connected to the program selection control unit IO of the television receiver l in FIG.
R18 to 20, and (7) a video control unit 1 that controls the storage operation and playback operation of the VTRs 18 to 20, respectively.
5 to 17, and a program editing control unit 25 that controls the video control units 15 to 17 and the program switching instruction detection unit 13 according to a procedure set in advance by the viewer. There is. Note that the VTRs 18 to 20 may be provided outside the television receiver 30.

Control signals for program multiplex broadcasting from broadcasting stations 2.3 are different for each transmitting device [(main program transmitting device 21, subsidiary program transmitting device 22, 23 in Fig. 1), and each program is controlled by each control signal. Identification is possible.

This allows the program editing control unit 19 to identify the program being received based on each control signal input by the viewer.

Furthermore, the program editing control unit 25 sends out video identification information indicating that the programs recorded on the VTRs 18 to 20 can be played back.

With the television receiver 30 having such a configuration, the viewer can more freely re-edit the program multiplex broadcast broadcasted from the broadcasting station 2 in FIG. 1.

Below, the television receiver 30 in the embodiment of Mizui 2
The operation according to the present invention will be explained.

The basic operation when no prior operation instructions from the viewer have been set in the program editing control section 25 will be explained.

When the program switching instruction detection unit 13 detects the viewer's selection of a secondary program while receiving a program multiplex broadcast via the tuner m5, the output program selection control unit 14 selects the secondary program reproduced by the video/audio signal extraction unit 6. The selected signal is outputted to the audio/video output section 8 via the output control section 7. At this time, the program editing control section 25 activates the storage operation of the VTR 18 via the video control section 15 based on the detection of the subsidiary program selection by the program switching instruction detection section 13. In this way, the program editing control section 25 of this embodiment automatically stores the main program when selecting the subsidiary program. However, the setting of the control procedure may be arbitrarily selected by the viewer. For example, when the program multiplexing detection unit 11 detects the start of broadcasting of program multiplexing, it automatically changes the secondary program to V.
It may also be stored in TR18.

Next, the program g collection control section 25 controls the program switching instruction detection section 13.
The storage operation of the VTR 18 is stopped via the video control section 15 based on the detection of an instruction from the viewer to stop the output of the subsidiary program, or the detection of the end of the program multiplex broadcast by the program multiplex detection section 11. By storing the main program on the VTR 18 in this way, the viewer can later watch the main program while watching the sub-program.

Furthermore, when the output to the video and audio output section 8 changes to the main program, the program editing control section 25 outputs video identification information indicating that the program recorded on the VTR 18 can be played back.
The signal is sent to the video/audio horn section 8 via the 9 section 7. At this time, if the subsidiary program is continuing, the video and audio horn part 8
At the same time, identification information indicating that the program multiplex broadcast is being received is also sent from the identification information sending diagram 12 at the same time.

In this way, the viewer can obtain information on the programs available for viewing and can select the output of the desired program.

Note that the program editing control section 25 controls the storage operation, playback operation, etc. of the VTRI 8 via the video control section 15 based on the detection of an arbitrary operation instruction from the viewer by the program switching instruction detection section 13. You can also do that.

Furthermore, VTRs 19 to 20 and video control section 16
~ 17 is also used, by the viewer setting the program for screen display and recording of the broadcast program in the program editing control section 25 in advance based on newly developed TV programs etc., the viewer can change the combination of programs of the viewer. Increased freedom.

The following is an explanation of how viewers can edit a variety of programs like this! I do lJ.

FIG. 4 is an explanatory diagram showing an example of a program editing state by the television receiver 30 in FIG. 3. FIG. 2 is a time chart showing an example of a broadcast configuration and broadcast order.

The program that started broadcasting at time t is 1, t,...L.

The program is multiplexed at each time, and each multiplexed program exists as a separate program.

That is, there are a political program 411, a social program 412, a sports program 413, and a weather forecast 414 as the main programs broadcast according to standard program editing, that is, the main program 410, and the programs related to each of these main programs Supplementary programs such as commentary, that is, auxiliary programs 420 and 43
0, political commentary program 415, social commentary program 416,
There is also a professional baseball commentary program 417.

In this embodiment, the main program 410 each provides digest-like content, and the sub-programs 420 and 430 provide more detailed explanations of the respective main programs.

Time t1-12 in the figure. is also a turning point indicating a program change.

In this way, in Figure 4 (a), in addition to the four main programs, the broadcasting station prepares in advance subsidiary programs that provide detailed explanations related to each main program, and displays these main programs and their main programs. and related related programs are multiplexed and broadcast in the same time slot.

Then, during the broadcast of the main program, there is a branching point in the broadcast, and the viewer can watch the program he or she has selected after the branching point. For example, the viewer can see the turning point at the time [
1, the user can view either the main political program 4II or the subordinate political commentary program 415, whichever is selected.

If the political program 411 does not have particularly new interesting content, the viewer does not switch and the television receiver 30 in FIG.
Show political program 411 until it reaches 2. However, if the political program 411 is of interest, the viewer issues an instruction to switch to the political commentary program 415, and the television receiver 30 in FIG. Switch to political commentary program 415.

In this way, the viewer can easily select the desired program.

Next, when the viewer sets and registers the operating procedure in the number M11Q collection control unit 25 in FIG. 3 based on a program guide in a newspaper or the like, the television receiver 30 in FIG. 3 performs the following operations, for example. can be done.

Here, the program editing control section 25 in FIG.
The output order of display programs is from time to time [1 to political program 411, then political commentary 4]5, and then from time t1 to
Political program 411 and social program 412 from to time t,
Next, social commentary 416, and social commentary 412, sports 413, and weather forecast 414 from time t, and time t.
Please do not watch professional baseball commentary 417 from .

In addition, since the program multiplexing detection unit 11 shown in FIG. 3 can detect control signals that identify each program, the procedure for setting the output order of display programs can be applied to each control signal for each program in the program guide. Corresponding identification barcodes may be assigned and settings may be made in the order in which the barcodes are read.

The operation based on the above-mentioned procedure registered in the program editing control section 25 shown in FIG. 3 will be described below.

First, if multiplex broadcasting of the political commentary program 415 is started at time t while the political program 411 is being received, the output program is switched from the political program 411 to the political commentary program 415. At the same time, the main program 410 is stored on the VTR 13 shown in FIG. Also, from the time, the companion program 43 of the social commentary program 416
0 is also started, so the social commentary program 416 is stored by the VTR 19 in FIG. In addition, the VTR 19 in this figure 3
The storage operation of the social commentary program 416 by the time ends earlier.

When the political commentary program 415 ends, VTl≧1 in Figure 3
The main program 410 from time t stored in step 8 is played back and output (displayed). At the same time, the VTR 20 shown in FIG. 3 continues the storage operation of the VTR 18.

As the playback of the VTR 18 shown in FIG.
The social commentary program 4]6 stored in R19 is played back and displayed. When the reproduction of this social commentary program 416 is completed, the interrupted reproduction and display of the VTR 18 in FIG. 3 is resumed. Furthermore, when the reproduction and display of the VTR 18 of FIG. 3 is completed, the main program 410 whose storage operation has been continued is reproduced and displayed by the VTR 20 of FIG.

Incidentally, if the political commentary program 415 being played is not what he expected, the viewer can also switch to the sports program 413 of the main program 410 via the remote control 9 in FIG.

In this way, by setting and registering the operating procedure in advance in the program editing control section 25 in FIG. 3, the viewer can easily edit the program as desired.

FIG. 4(b) shows how the program multiplex broadcast shown in FIG. 4(a) is performed by the video and audio output unit of FIG. 8 shows the flow of the broadcast screen output.

When the time [,] is reached while the political program 411 is being output, normally,

0 is displayed as "Explanation provided".

However, in this embodiment, the screen is switched to the political liberation screen 81, which is a subsidiary program, based on a procedure preset in the program editing control section 25 shown in FIG. On this political commentary screen 81, identification information 441 indicating that the main program is being multiplexed is displayed as "main". During this time, on the VTR 18 in Figure 3,
Main political program 411. Also, social programs 412 and the like are stored.

When the political commentary on the secondary program ends, the screen normally returns to the main program, the sports screen 82, and the rVTR of the video identification information 442 indicating that the seven stored programs can be played back.
Display J. In addition, if a subsidiary program of the professional baseball commentary program 417 related to the main program being output on the sports screen 82 is being multiplexed, the identification information 443 indicating the program multiplexing is set to "
"Explanation provided" is displayed. Here, if the viewer selects the professional baseball commentary program 417, the screen switches to the professional baseball details screen 83. On this professional baseball details screen 83, identification information 444 indicating that the main program is being multiplexed is displayed as "main".

However, in this embodiment, the program editing control section 25 in FIG. 3 is set in advance to play the stored main program.
The screen switches to a social screen 84 on which the social program 412 stored on the VTR 18 in FIG. 3 is played. This social screen 84 includes identification information 445 indicating that the main program is being received as "main", and identification information indicating that the secondary program 4]2 that is being played is multiplexed. 446 is displayed as "Explanation provided".

In this way, in the embodiment of Section 2, a plurality of VTRs are controlled according to an operation procedure arbitrarily set in advance. Due to this,
The viewer can edit the program in accordance with the viewer's own wishes.

In the second embodiment shown in FIGS. 3 and 4, there are a plurality of video control sections that respectively control the operations of a plurality of VTRs, and a procedure set in advance for the operation of these video control sections by the viewer. A separate program editing control section is provided. However, by providing the program editing control section with the functions of the video control section, the program editing control section can control the operations of multiple VTRs.
A configuration may also be used. Furthermore, although the video identification information is sent from the program editing control section to the output control section, it may also be sent via the video control section or a VTR.
