Abstract

본 발명은 TV수상기의 방송무신호 연속 입력시의 자동채널 탐색장치에 관한 것으로, 특히, 사용자의 TV시청시 타방송의 채널로 절환시에 이미 종료되어 있거나, 시작되지 않은 방송프로일 경우 , 방송무신호가 감지되는데, 이때, 마이크로프로세서에서 상기의 방송무신호 감지횟수를 카운트하여 일정횟수 이상일때는 모든 방송채널에 대하여 방송신호가 잡히는 채널을 자동기억하는 방송채널 탐색기능을 실행하여, 현재 시청할 수 있는 모든 채널을 재설정하여, 사용자로 하여금 바온채널 검색을 용이하게 하도록 된 것인바, 이는 사용자의 채널절환에 따른 편의를 최대한으로 제공하게 된 발명인 것이다.The present invention relates to an automatic channel search apparatus for continuous input of a broadcast free signal of a TV receiver. In particular, when the user switches to a channel of another broadcast when watching a TV, the broadcast program is already terminated or is not started. When no signal is detected, the microprocessor counts the number of times of detection of the no signal and executes a broadcast channel search function that automatically remembers a channel in which a broadcast signal is caught for all broadcast channels. By resetting all channels, the user is to facilitate the on-channel search, which is an invention that provides the maximum convenience for the user's channel switching.
