Description

Description: TECHNICAL FIELD The present invention relates to a one-way communication television broadcasting system, and in particular, multiplexes a plurality of programs and broadcasts them at the same time so that viewers can make independent decisions. The present invention relates to a television receiving apparatus which enables a combination of programs based on each other and is suitable for efficiently broadcasting information corresponding to each viewer's desire.

[Conventional technology]

At present, there are various communication devices and communication systems for transmitting intentions between remote locations.

In particular, image information is the most effective communication information for visually disclosing information, and various visual image information transmission techniques have been developed for more efficient communication.

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

At present, a television broadcasting system is one of the most widely used image information communication technologies.

2. Description of the Related Art In a television broadcasting system, a television receiver receives video program information transmitted from a television broadcasting station having program production facilities and transmission facilities, and displays a moving image.

There are the following methods for providing such image information according to the wishes of an unspecified number of viewers.

For example, there are a plurality of television broadcasting stations on the provider side of a program, and each broadcasts video program information on a unique television channel. Then, the television receiver selects a desired one from each channel and outputs the selected one.

In addition, PP1389, 1460-1461, "Electronic Information and Communication Handbook" (1988, published by Ohmsha) edited by IEICE
And PP214 of Noboru Saikai, "FM / TV Audio Multiplex Tuner and Its Uses" (1980, published by Seibundo Shinkosha)
As described in Nos. 226 to 226, a method of multiplexing a plurality of sounds on an audio channel of a television channel has been put to practical use, whereby a stereo broadcast or a bilingual broadcast is performed, and The degree of freedom in programming has been expanded.

For example, a main carrier with a Japanese broadcast main signal and a frequency modulation (FM: Fre
quency Modulation), and a subcarrier of AM (Amplitude Modulation) with a control signal for allowing the television receiver to determine whether it is broadcasting in two languages. The signal is broadcast as a television audio multiplex from a broadcast station on an audio carrier next to the television video carrier. Then, the television receiver that has received the television audio multiplex broadcast separates the composite signal via a filter or the like by a demodulation unit (adapter). Further, the main signal of the Japanese broadcast and the sub-signal of the foreign language broadcast are demodulated by the FM detector and output as sound via a power amplifier, a speaker, and the like. The control signal is demodulated by the AM detector, and is used for driving a changeover switch (for example, switching from a foreign language to Japanese) and for driving a display circuit for a broadcast type (bilingual broadcast or stereo broadcast). .

As described above, in the current television receiver, the viewer can change the desired program by switching the television channel, and change the audio in the same program on the same television channel.

On the other hand, CAPTAIN (Chara), which changes programs by bidirectional communication, provides information that more flexibly responds to the wishes of viewers using this television receiver.
cter And Pattern Telephone Access Information
Network: character graphic information network) and CATV (Cable TV: cable television broadcasting).

In CAPTAIN, for example, as described in JP-A-1-316869, a broadcasting station displays a program guide on a television receiver of each family through a telephone line, and a viewer watches a telephone while watching the program guide. Input the identification number of the desired program as a terminal. Then, based on the identification number input by the viewer, the broadcast station changes the program to a program desired by the viewer and broadcasts the program.

The advantage of such CAPTAIN broadcasting is that, for example, by using a television receiver, the viewer can receive a service of providing information appealing to sight and hearing, and the viewer can use his or her own That is, it is possible to select a service to be received as desired.

On the other hand, CATV communicates high-frequency (several hundred MHz) video data and attached audio by wire,
A bandwidth capable of accommodating several tens of channels can be used, and television programs can be multiplexed.

Further, as an example in which a viewer uses a computer to program a plurality of pieces of related moving image information, see, for example, "Nikkei Electronics 1989 4-17" (1989).
Year, published by Nikkei BP).
That is, a screen having an icon associated with a moving image stored on a video disc is displayed on a display unit of a computer, and a desired moving image is displayed on a television receiver based on a click of a viewer's icon. is there.
In this way, the viewer not only unilaterally receives the given program sequence, but also allows the viewer to actively participate in watching the video.

[Problems to be solved by the invention]

The change of the video program information using the two-way communication of the prior art is suitable for an advertisement search by a viewer or a database search.

However, viewer programs (services) in two-way communication
In the selection of (1), it took time to change the program, and the information intended by the broadcast station was not efficiently transmitted.

Further, in the conventional television broadcasting which is one-way broadcast communication, the content and organization of one program cannot be freely changed according to the viewer's preference. For this reason, a program composed on the broadcast station side, that is, information is broadcast to all viewers with the same content.

For example, in a professional baseball night game, if the game does not end within a predetermined time,
The user wants to continue the night game broadcast more than the scheduled next program, and the other viewers want the next program as scheduled. In this case, in order to cope with the desires of both parties, the broadcasting station must transmit each broadcast using different television channels, which imposes a heavy burden on the broadcasting station in terms of facilities and program operation management. In general, it was not possible for a single broadcasting station to respond.

Also, news programs such as politics and science are boring programs for viewers who have sufficient background knowledge about the information to be broadcast, depending on the content structure of the programs.
For a viewer who does not have sufficient background knowledge about the information to be broadcast, the program cannot be understood, and the program is unattractive to both viewers.

In addition, a method of selecting and displaying a moving image using a computer requires a work of associating a moving image stored in a video disk with an icon on a display screen of the computer in advance. Cannot be selected in real time.

Thus, in the conventional television broadcasting system,
It has not been possible to efficiently provide programs that flexibly respond to the wishes of viewers with different tastes.

An object of the present invention is to solve these problems of the prior art, and to edit the content of a program broadcast by television in one-way communication to a configuration desired by a viewer on the television receiver side, thereby improving the efficiency. An object of the present invention is to provide a television receiver capable of transmitting information.

[Means for solving the problem]

In order to achieve the above object, the television receiving apparatus of the present invention has the following features: (a) that each television broadcasting station apparatus performs broadcasting by multiplexing a plurality of pieces of television program information on a selected channel; A program multiplex detection unit for detecting and detecting a control signal for identifying each television program information multiplexed together with the program information, and based on the detection result, the television program information is being multiplex broadcast on a selected channel. An identification information sending unit that outputs information to the video / audio output unit that informs the viewer that the TV program information is to be selected and detects an instruction to select TV program information from the viewer based on the information. And an output program selection control unit for selecting television program information corresponding to the detection result and outputting the selected television program information to the video / audio output unit.

Also, (b) a program editing control unit for transmitting television program information, which is not selected and output by the output program selection control unit, to a video device and causes the video device to record the program information.

(C) storing a preset TV program selection procedure, and controlling the output of the TV program and the recording of the TV program by the video device in accordance with the stored procedure, that is, the preset TV program selection procedure; It is characterized by doing.

[Action]

In the present invention, a television broadcast station uses not only sound but also one television channel (broadcast band).
Multiple broadcasts of a plurality of video program information. In other words, video program information that is constantly broadcast is broadcast as a main program, and video program information that is multiplexed on the main program is broadcast as a subprogram.

During program multiplex broadcasting, the screen of the main program or slave program
An identification indicating that the program is being multiplexed is displayed. The viewer can understand, for example, the existence of the subsidiary program by this identification display, and can change the display to the subsidiary program. In this way, the viewer can know, for example, the information related to the main program in more detail in the subsidiary program. Conversely, if you do not select a slave program,
There is no waste of watching unnecessary information.

After the end of the viewing of the sub-program, the reception screen is automatically switched to the main program, and the viewer can continuously watch the main program.

Further, at the same time when the display is changed from the main program to the subordinate 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 the subsidiary program also
It can be provided to the viewer later.

Also, a plurality of storage devices such as video devices are connected, and drive control is performed for each of the plurality of multiplexed video program information. As a result, it becomes possible to store the main program and the sub-program broadcasted during the reproduction and display of the stored program. In addition, the viewer can arbitrarily set and register the drive control procedure of each storage device in advance, so that the master program and the slave program can be freely selected, and the viewer can select a desired program. Can be edited.

〔Example〕

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

FIG. 1 is a block diagram showing a first embodiment of a configuration according to the present invention of a television program multiplex broadcasting system provided with a television receiving apparatus of the present invention.

The television program multiplex broadcasting system according to the present embodiment includes broadcast stations 2 and 3 that broadcast a program multiplex broadcast obtained by multiplexing a main program, a subsidiary program, and program identification information (control signal) for identifying each program; A television receiver 1 for selecting and displaying either a main program or a sub-program from multiplexed programs based on a viewer's operation is connected to a television receiver 1 via a transmission line 4 made of a wired cable.

The broadcasting station 2 includes a main program transmitting device 21 for transmitting a main program, subordinate program transmitting devices 22 to 23 for transmitting a subordinate program, and a main program transmitting device.
A multiplex transmission device 24 multiplexes transmission programs from the transmission program 21 and the slave program transmission devices 22 to 23 in the same broadcast band and transmits the multiplexed program information. The broadcasting station 3 has the same configuration. In addition, when multiplexing the main program and the slave program, the multiplex transmission device 24 multiplexes the program identification information for determining the content of the multiplexed program as the control signal and transmits the multiplexed program multiplex information.

The television receiver 1 tunes a television broadcast from the broadcast stations 2 and 3 and receives it. The television broadcast (including a multiplexed program) received by the tuner 5 is converted into a video or audio signal. A signal extraction unit 6 that separates and reproduces each frequency band in which the video signal exists, and extracts the extracted video and sound, an output control unit 7 that outputs the video and sound reproduced by the signal extraction unit 6 to a video and audio output unit 8, According to the present invention, a program selection control unit 10 for selecting a program to be reproduced by the signal extraction unit 6 and displayed on the video / audio output unit 8 is provided. It should be noted that the operation of the receiving operation by the viewer is performed via the remote controller 9.

The program selection control unit 10 detects, based on the control signal extracted by the signal extraction unit 6, a program that detects that the program information selected and received by the tuner unit 5 is a multiplex of the main program and the subprogram. A multiplex detection unit 11, an identification information transmission unit 12 for transmitting identification information indicating that the received program information is program multiplex information to the output control unit 7, and switching of a viewer's display program transmitted via the remote control 9 A program switching instruction detecting unit 13 for detecting an instruction, based on a detection result of the program switching instruction detecting unit 13 and a detection result of the program multiplex detecting unit 11, selecting and outputting a main program or a slave program reproduced by the signal extracting unit 6. It comprises an output program selection control unit 14 to be sent to the control unit 7.

In the present embodiment, a wired cable is used for the transmission path 4. However, wireless broadcasting may be used.

Further, a frequency division method is adopted as a multiplexing method for transmitting a plurality of programs at the same time.

With such a configuration, the television program multiplex broadcasting system of the present embodiment provides a program corresponding to various needs of the viewer.

Hereinafter, the operation of the television program multiplex broadcasting system of the present embodiment according to the present invention will be described.

For example, if a broadcast program of a professional baseball game is broadcast from the broadcast station 2 and the game does not end within a predetermined time, the broadcast station 2 multiplexes and broadcasts the program. That is, the progress of the program scheduled in advance (program program, program table)
For example, a weather forecast, a music program following the weather forecast, and the like are set as the main programs from the main program transmission device 21 based on the main program. In addition, it is assumed that a professional baseball night game relay is a subordinate program from the subordinate program transmission device 22. Then, the multiplexed signal is multiplexed with the control signal by the multiplex transmission device 24 and broadcast as a multiplex broadcast of the program.

The television receiver 1 outputs a weather forecast program to the video / audio output unit 8 when the professional baseball night game relay is completed. Simultaneously, the program multiplex broadcast is detected by the program multiplex detector 11 based on the control signal extracted by the signal extractor 6. Then, the identification information sending unit 12 sends the identification information indicating that the program is being multiplexed to the output control unit 7, and displays it on the screen of the video / audio output unit 8 displaying the weather forecast.

Here, if the viewer wants to continue watching the professional baseball night game instead of the weather forecast, he or she inputs a program switching instruction via the remote controller 9. The switching instruction is detected by the program switching instruction detecting unit 13, and based on the detection, the output program selection control unit 14 selects the subordinate program information, that is, the professional baseball night game relay, from the signal reproduced by the signal extracting unit 6. And sends it to the output control unit 7. Then, the video / audio output unit 8 outputs a professional baseball night game relay via the output control unit 7.

In this way, the viewer can watch the professional baseball night game broadcast.

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

FIG. 2 is a flowchart showing an embodiment of the operation of the television receiver 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 broadcasting station (step 202), based on the signal reproduction result of the signal extraction section (step 203), the program multiplex detection section determines whether or not the program is a multiplex broadcast. Determine whether or not (step
204).

If it is a program multiplex broadcast, the identification information sending section sends information indicating that the program multiplex broadcast is being received, and outputs the information to the video / audio output section (step 205). Then, the program switching instruction detecting unit determines an instruction from the viewer (step 206), and detects whether the selection of the viewer is the main program or the subordinate program (step 207).

If the instruction from the viewer is to select the main program, the output program selection control unit selects the output of the main program reproduced by the signal extraction unit (step 208). Then, it outputs to the video / audio output unit via the output control unit (step 209).

If the end of the slave program, that is, the end of the multiplex program broadcast is detected by the program multiplex detection unit during the output of the main program (step
210), the transmission of information during reception of the program multiplex broadcast from the identification information transmitting unit is stopped (step 211).

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

In step 207, if the viewer selects a slave program, the output program selection control unit selects the slave program reproduced by the signal extraction unit (step 213), and outputs it to the video / audio output unit via the output control unit. (Step 214).

When the end of the slave program is detected by the program multiplex detection unit (step 215), the output to the video / audio output unit is switched to the main program reproduced by the signal extraction unit by the output program selection control unit (step 216). Then, the process proceeds to step 211, in which the transmission of information during reception of the program multiplex broadcast from the identification information transmitting unit is stopped.

If it is determined in step 204 that the broadcast being received is not a program multiplex broadcast, the program reproduced by the signal extraction unit is output to the video / audio output unit (step 217).

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

Next, recording the program on the television receiver shown in FIG.
Storage device for recording, for example, VTR (Video Tape Re
A system for connecting a corder, a video tape recorder, etc., and editing a multiplex broadcast from a broadcasting station into a program more suited to the viewer's wishes will be described.
