Abstract

PURPOSE: An apparatus for automatically selecting a broadcasting station using a code during movement is provided to automatically select a corresponding broadcasting station of a next area when a broadcasting area of the broadcasting station goes off and a receiving level is decreased by recognizing a designated code of the broadcasting station heard through a car audio during movement when an intrinsic code designated by the broadcasting station is transmitted. CONSTITUTION: A code transmitter and a synthesizing device are installed in a transmitting unit of each broadcasting station for synthesizing a broadcasting signal and a broadcasting station intrinsic code and transmitting the synthesizing signal. A code detecting and recognizing unit is installed in a receiving-side radio for memorizing codes of broadcasting stations, re-searching a memorized code, and maintaining the memorized code when a hearing signal is degraded at a uniform level or less.

Description

Device for automatic selection of broadcasting stations using codes {Code type broadcasting (a key [local] station) auto selection system}

The present invention is almost impossible to find the broadcast while listening to the broadcast while listening to long distance or driving while changing the region of the station that you are listening to in the region, even if you can find it difficult to give up the broadcast and listen to other broadcasts or cassettes Give up or listen. Nowadays, there is a way to find the frequency somewhat conveniently by specifying the adjacent frequency received by frequency SCAN, but this method is also difficult. Especially at high speeds, it may affect safe driving. Therefore, I came up with a way to alleviate this inconvenience, so I filed my application first.

The technology used in the product of the present invention transmits a separate unique code designated for each broadcasting station along with the broadcasting station, and then receives it out of the broadcasting area of the broadcasting station by recognizing the designated code of the broadcasting station that is listening on the moving radio (car audio, etc.). The station code selection method automatically selects the corresponding station in the next region when the level drops.

Is a block diagram summarizing the basic schematic diagram.

The configuration will be described with reference to the accompanying drawings.

On the transmitting station side, a code transmitter and a synthesizing apparatus are provided in the transmitting unit of each broadcasting station scattered throughout the country to synthesize and transmit the same broadcasting station unique code together with the broadcasting signal. That is, if the KBS1 radio code is 001 and the MBC radio code is 002, all KBS1 radios in each region of the country transmit 001 with the broadcast signal even though the transmission frequency is different. Of course, each local MBC radio also transmits its own code 002.

On the receiving radio, a code detection and recognition device is installed to memorize the code of the station being listened to, and when the signal is weakened below a certain level, the stored code is searched and selected again to select and store the code even if the frequency changes. Have it.

So, if the listener who listened to KBS1 radio was moving from Seoul to Busan, and kept the code as the station that he was listening to, he would automatically select the station of the same station in the neighboring area and select Seoul 1 radio, Cheongju 1 radio, Daejeon 1 radio, Daegu 1 radio ... Busan KBS1 radio can be heard without any special operation.

The present invention (design) can be installed in the radio receiving portion in the portable radio or TV, and car audio for people who travel frequently, freely select the station, and in the case of car audio by reducing unnecessary operation during driving It is expected to work.
