Description

Broadcasting transmission / reception system using communication channel {BROADCASTING SYSTEM ON COMMUNICATION CHANNEL}

The present invention relates to a broadcast transmission and reception system, and in particular, a communication channel through a communication medium such as a DC cable, a twisted pair for a telephone, a coaxial cable, a microwave cable for an satellite, an optical fiber cable, etc. The present invention relates to a broadcast transmission / reception system using a communication channel capable of receiving a broadcast of a local station.

In general, broadcasts can be classified according to radio waves used as transmissions of communications for the purpose of being directly received by the public.

In other words, radio broadcasting uses medium wave (AM broadcasting), short wave (short wave broadcasting, international communication), and microwave (FM broadcasting) as a broadcast by voice waves, and TV broadcasting uses microwave and microwave.

In other words, when a broadcast station carries a voice or voice and an image on a radio wave, it is reproduced by a radio receiver and a TV receiver, which are receivers, to provide voice and video to the general public.

However, these radio and TV broadcasts have regional characteristics due to the nature of radio waves, so they could not listen to such radio or watch TV abroad. As a result, domestic broadcasters produced and provided video broadcasts so that overseas citizens could listen to and watch their own broadcasts. However, this method is inadequate in many ways because the broadcasting can be accessed at a time difference, and accordingly, the simultaneous listening and watching of the broadcasting was required.

Accordingly, the present invention has been made in view of this, and an object of the present invention is to transmit / receive a broadcast using a communication channel that enables a foreign country to listen to a radio broadcast or watch a TV broadcast in a foreign country with almost no time difference by using a communication channel most connected anywhere in the world. To provide a system.

It provides a broadcast transmission and reception system using a communication channel, characterized in that consisting of.

Such a system comprises the steps of transmitting broadcast data compressed by receiving a broadcast wave from a domestic broadcasting station 11 at a domestic broadcasting relay station 12 to an overseas broadcasting relay station 13 of each country, and received by the overseas broadcasting relay station 13. Transmitting the stored broadcast data when the subscriber's terminal 14 accesses the communication channel, and decompresses the broadcast data received by the subscriber's terminal 14 so that the subscriber can listen to and watch radio and TV broadcasts. Through this step, the local broadcasting is provided to the subscribers having the terminal 14.

Hereinafter, with reference to the accompanying drawings, a radio broadcast as a preferred embodiment of the present invention will be described in detail as follows.

(Example)

1 is a block diagram briefly showing the configuration of the present invention. Referring to the configuration thereof, a domestic broadcasting relay station 12 capable of receiving broadcast signals from the domestic broadcasting station 11, compressing them, and transmitting compressed broadcast data is installed, and transmitted from the domestic broadcasting relay station 12. An overseas broadcasting relay station 13 is provided for receiving the compressed broadcast data and transmitting the compressed broadcast data to the terminal 14 of the subscriber. The foreign broadcasting relay station 13 selects and executes agents of each country.

In addition, the subscriber who resides in a foreign country is provided with a terminal 14 connected to the foreign broadcasting relay station 13. The overseas broadcasting relay 13 of the foreign agent and the terminal 14 of the subscriber are connected to a telephone network through a communication medium such as a DC cable, a twisted pair for a telephone, a coaxial cable, a microwave line for an satellite, an optical fiber cable, and a local area network (LAN). A communication channel such as a high speed communication network is used.

The subscriber's terminal 14 is a terminal having a function of releasing the compressed state of the broadcast data received through the communication channel so that the listener can listen with voice, etc., which has a unique ID and switches When it is activated (ON) by means of means that it is set to perform automatic dialing (Dialing) to the national broadcasting station 13 of the corresponding station.

As such, when the domestic broadcasting relay station 12, the overseas broadcasting relay station 13, and the subscriber terminal 14 are distributed, the terminal is operated as follows.

First, the local broadcasting relay station 12 receives the radio wave of the domestic broadcasting station 11, compresses the broadcasting data, and transmits the broadcasting data to the overseas broadcasting relay stations 13 around the world. This can be exemplified by using the Internet or an international telephone network.

The foreign broadcasting relay station 13 stores the broadcast data compressed and received from the domestic broadcasting relay station 12, and when the terminal 14 having each unique ID is connected through the communication channel, that is, the subscriber 14 is connected to the terminal 14. When operating the service, the ID of the connected customer is checked and the compressed broadcast data is transmitted to the subscriber's terminal 14.

The subscriber's terminal 14 decompresses the received broadcast data and reproduces the radio broadcast like a general radio receiver.

At this time, the broadcast listened to the terminal 14 is performed with an error within about 1 hour based on the real time of the corresponding station.

On the other hand, when the broadcast listening time reaches 1 hour, the terminal 14 automatically dials to receive broadcast data continuously, so that the continuous listening is performed like the actual radio broadcast listening.

After the terminal 14 is registered as a member of the designated agent as a member and receives a unique ID, it is possible to listen to the broadcast regardless of which region it moves to, at the expense of a telephone fee.

In addition to the fixed broadcast, subscribers can communicate with each other by using a separate channel, which can transmit a call, a message, etc. to another subscriber through a broadcasting center using a unique ID. When using such a separate channel, it is possible to deliver news and information by immediately sending an emergency accident, news, etc. regardless of time difference by country.

In addition, when the terminal 14 is connected to a wireless cellular phone, it is possible to listen to broadcasts transmitted from the domestic broadcasting relay station 12 while traveling or in a vehicle.

In the above embodiment, the radio broadcasting is described as an example, but the same applies to the TV including the image.

As described above, the present invention is realized by transmitting compressed broadcast data for a short time through audio and video compression technology and reproducing the broadcast data through decompression to a terminal of a consumer. Besides, it is possible to listen to radio broadcasting and watching TV broadcasting.

As described above, the present invention provides a terminal capable of listening to and watching radio and TV broadcasts in the home country by providing a corresponding terminal in a place where a communication channel reaches even in a foreign country where domestic broadcasting does not reach. Listen and watch. In addition, when a terminal is installed in a hotel, foreigners staying at the hotel can operate and listen to the broadcast of their home country by operating a broadcast selection button of the terminal, thereby providing a high level of service. In particular, the present invention provides local residents living abroad. Since it is possible to listen to and watch a broadcast simultaneously with the broadcasting of its own country, it is possible to promptly access the news or broadcasting of the home country, thereby obtaining an additional effect of inducing patriotism and unity of nations.
