Claims (1)

마이컴(1)에 연결된 자동 프로그램 채널 조사용 뷰스위치(SW1)가 온되었는가를 계속 검출하여 뷰스위치(SW1)가 온이되면 현재의 채널 데이타를 소정의 메모리에 기억시킨 다음 채널을 업시켜 동기신호(Sync)가 입력되는가를 계속 검출하는 제1과정과 ; 상기 제1과정에서 동기신호가 입력되면 소정시간 동안 화면에 영상신호를 출력시킨 다음 채널을 다시 업시켜 현재의 채널이 최초에 기억시킨 채널 데이타와 같은가를 검출하여 같지 않으면 다시 동기신호가 입력되는가를 판별하여 동기신호가 입력되었으면 상기 과정중 소정시간 동안 화면에 영상신호를 출력시키는 과정으로 되돌아가되 동기신호가 없거나 업된 채널 데이타가 최초에 기억된 채널 데이타와 같으면 1회의 채널 조사를 마치고 종료하는 제2과정으로 이루어 짐을 특징으로 하는 영상기기에서의 채널 자동 선택 방법.It is continuously detected whether the view switch SW 1 for automatic program channel irradiation connected to the microcomputer 1 is turned on. When the view switch SW 1 is turned on, the current channel data is stored in a predetermined memory, and then the channel is turned up. A first step of continuously detecting whether a synchronization signal (Sync) is input; If the synchronization signal is input in the first step, the video signal is output on the screen for a predetermined time, and then the channel is turned up again to detect whether the current channel is the same as the channel data stored in the first place. If it is determined that the synchronization signal is input, the process returns to the process of outputting the video signal to the screen for a predetermined time during the above process. Automatic channel selection method in a video device characterized by consisting of two processes. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
