Description

Directional Television Broadcasting System

The conventional TV broadcasting system transmits a broadcast to an unspecified number, and the conventional TV broadcast receiver only has a function of receiving a TV broadcast from a TV station, and the broadcasting station has a technology for transmitting a TV program to an unspecified number. There was no. Not only is it impossible to broadcast to a certain number or a certain number of people, but when a disaster or war breaks out when the viewer turns off the TV and goes to bed, the broadcasting station is forced to turn on the viewer's TV and transfer the channel to a specific disaster broadcasting channel. Remote control such as waking up people who were sleeping by turning up the volume was impossible, making it impossible to operate emergency disaster broadcasting.

In order to receive a broadcast by scrambled broadcast program in cable broadcasting or satellite broadcasting and descramble in a set-top box (converter) for receiving a broadcast, a technology for controlling a receiver of the broadcast program has been developed, but in this case, expensive descramble Since a device is required and the scramble method is different for each local cable broadcasting station, several local cable broadcasting stations cannot be operated together in a wide area.

In addition, since the public address TV is not assigned an address, and a broadcasting station has not developed a technology for transmitting specific data for each address, it is impossible to construct an E-mail system using a TV network. In addition, even if a viewer with a minor asked a broadcasting station not to transmit a specific program, the broadcasting station had no means of accepting a request of each viewer to enable or disable the reception of a specific program in a specific household.

In order to solve the above problems, in the cable TV broadcasting or wireless TV broadcasting system, the broadcasting station that transmits the broadcast program specifies the receiver of the program in the broadcast program, and the group that is allowed to receive the broadcast and the broadcast reception are restricted. By inserting and broadcasting data signals that are controlled in groups, the broadcasting system can broadcast a specific program to a specific group if necessary by the broadcasting station, and the technology of remotely controlling the TV receiver of each viewer by address in the TV broadcasting station Off Provide emergency disaster broadcasting such as turning on the TV of the state and forcibly transferring the channel to a specific channel when watching other channels, and providing effective control of the e-mail service and restriction programs for youth viewing. And technology to enable class-specific educational broadcasting.

As shown in Figs. 1 and 2, the system of the present invention inserts a host computer 1 for transmitting control data signals inserted into a broadcast program from a broadcasting station and inserts data transmitted by the host computer into the broadcast program. A data processing means (2), a signal separating means (3) for separating the signal data inserted into the broadcast program in the receiver TV receiver, and a central processing unit for performing this according to the instructions of the control data separated from the signal separating means. (4), address specifying means (5) for designating an address of the central control unit, and communication modem means (7) in which a receiver can transmit a data signal to a host computer under the control of the central processing unit (4). And memory means 6 for storing and storing data addressed and received from the host computer of the broadcasting station.

Referring to the directional broadcasting function by the directional TV broadcasting system of the present invention configured as described above are as follows.

First, the TV station inserts and controls the TV group to be controlled by the host computer and the TV group not to be controlled by address, and inserts and restricts the viewing data into the broadcast program.

The data signal separating means 3 in the TV receiving the parental control data separates the data signal from the received program and transmits the data signal to the central processing unit 4, and the central processing unit if its address belongs to the parental control group. The specific channel indicated by the data does not operate even when the user calls it, and the channel transition control means 14-2 is controlled so that the channel is skipped.

If the user's address belongs to the viewing permission group, the channel is controlled to tune to the corresponding channel without executing Skip on the designated channel, thereby ensuring the viewing of the specific channel of the viewing permission group.

The operation of emergency disaster broadcasting is explained as follows.

First, when the host computer 1 of a broadcasting station inserts an instruction data signal into an emergency disaster program and sends out a program, the instruction data signal is separated from the data signal separating means 3 of the viewer's TV, and the central processing unit 4 Is sent to. When the emergency disaster instruction data signal reaches the central processing unit 4, the central processing unit controls the TV power supply control unit 14-1, and turns it on when the TV is in an off state. 14-2) to switch the channel to a specific channel, and control the TV volume control means 14-3 to adjust the volume to a pre-programmed level, so that the viewer can turn off the TV and go to bed. Or even if you are watching other broadcast programs, you will be watching emergency programs.

In addition, when implementing educational broadcasting, the broadcasting station inserts and transmits the applicant's address data into the educational broadcasting program for each class and subject, and receives the emergency disaster broadcasting by recognizing the address data in the data signal separating means (3) of the TV. In the same way as in the course registration is automatically transferred to the broadcast channel.

By allowing a host computer to watch a specific channel at a specific time by address, the host computer can configure different viewer groups by educational subject or time zone, thereby enabling class-specific training by class and time zone. The applied viewer can solve the test questions appearing on the TV screen and transmit the answers to the host computer through the remote control means 8 and the communication modem 7.

In addition, when a political party wants to educate or send a special broadcast to the members of the party, the program addressed to the above composition of the class will be transmitted, so that only special members can be given special broadcasts. It is possible to have a specific group broadcast that allows you to listen to the broadcast.

In addition, when the memory means 6 is added to the central processing unit 4, the host computer can transmit specific message data for each address as text, voice or video data, and the central processing unit 4 receives By storing the data in the memory means 6 and notifying the fact that the E-mail is received on the TV screen, the viewer receives the E-mail on the TV.

Each subscriber transmits and receives E-mail in both directions by sending E-mail data to be transmitted to the host computer 1 of the broadcasting station through the communication modem 7 together with the address data of the sender and the receiver.

Also, as the above-mentioned directional broadcasting becomes possible, when a broadcasting station broadcasts a program and requests that the subscriber block the reception of the program to the subscriber TV as a youth viewing restriction program, the broadcasting station inserts the viewing control data into the program. When broadcasting with the address data of the TV or terminal is limited, the central processing unit (4) of the addressed TV to limit the viewing of the youth by skipping the channel on which the program to be viewed in accordance with the indication data.

The system technology as described above is a signal separation means (3) for recognizing the data signal inserted into the broadcast program on each TV receiver and separating the data of its own address, and the central processing for controlling each function of the TV according to the instruction of the separated data The apparatus, the addressing means 5 of the central processing unit, the memory means 6 for storing and storing data, and the communication modem 7 for transmitting a data signal to the host computer 1 by the viewer. It can be configured to be attached as a separate set-top box, a technology applicable to both wired TV, wireless public TV or satellite TV broadcasting, and may include or remove the communication modem (7).

As described above, according to the directional TV broadcasting system of the present invention, in the TV broadcasting system which has been able to broadcast only to an unspecified majority so far, it is possible to send a specific broadcast to a specific majority or a small group if necessary, By being able to limit the viewing group of the program, it is possible to provide educational broadcasting for each class, which simultaneously lectures a plurality of classes by class and time zone in a wide area unit.

In case of an emergency, even if the TV is off or watching other channels, the emergency disaster broadcasting system can be controlled by forcibly turning on the TV, forcing the channel to be switched to a specific disaster broadcasting channel, and turning up the volume. It is to provide the technology to do it.

In addition, by inserting the data signal required for the broadcast program, the host computer of the broadcasting station transmits to the subscriber TV for each address, and the subscriber can transmit the necessary data to the broadcasting station, thereby enabling e-mail service through the TV. By broadcasting very much, it is possible to forcibly block juvenile harmful programs at the request of viewers.
