무신호시 티브이 채널의 자동절환 방식Automatic Switching Method of No Signal TV Channel

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제2도는 본 발명에 따른 티브이 회로도.2 is a TV circuit diagram according to the present invention.

제3도는 본 발명, 무신호시 티브이 채널의 자동절환 방식에 따른 제어 흐름도.3 is a control flowchart according to the present invention, an automatic switching method of a no-signal TV channel.

Claims (1)

채널의 선택 및 동기신호의 유무를 판단하는 기능을 갖춘 마이콤을 내장한 티브이를 구동하는데 있어서, 선택된 채널에 대하여 동기신호의 유무를 판단하여 동기신호가 존재하면 티브이를 현상태로 고정하고 소정시간동안 동기신호가 존재하지 않으면 채널을 자동으로 증가 또는 감소시킴과 아울러 화면에 온스크린으로 방송상태를 표시하며, 전환된 채널에 대하여 동기신호가 검출되면 채널을 고정하여 방송을 수신하고 동기신호가 검출되지 않으면 다시 채널을 절환하여 상기의 과정을 반복하다가 전 채널에서 동기신호가 검출되지 않으면 모든 채널의 방송이 종료된 것으로 인식하고 티브이를 자동오프시키는 것을 특징으로 하는 무신호시 티브이 채널의 자동 절환방식.In driving a TV with a built-in microcomputer with a function of selecting a channel and determining the presence of a synchronization signal, the presence or absence of a synchronization signal for a selected channel is determined. If there is no signal, the channel is automatically increased or decreased, and the broadcasting status is displayed on the screen.If a synchronization signal is detected for the switched channel, the channel is fixed to receive the broadcast. Switching channels again and repeating the above process, and if no synchronization signal is detected in all channels, all channels are automatically terminated and the TV is automatically switched. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
