Abstract

TV방송 밴드별 서치를 통하여 채널 서치 시간을 단축시킬수 있도록 마이콤(10), 튜너/IF단(12), AFT검출기(14), 동기검출기(16)를 포함하는 채널서칭 시스템에 밴드선택 모드스위치(18)를 부가하여, 상기 밴드 선택모드스위치(18)의 키입력에 따라 마이콤(10)의 PLL데이터, 클럭, 인에이블 신호가 각 밴드별로 구분되어 해당 선택밴드의 방송 채널만 메모리한후 종료시키고, 상기 밴드 선택모드 스위치(18)의 키입력이 없으면 전 밴드를 서치하여 전 방송 채널을 메모리 한 후 종료시킨다.Band selection mode switch in a channel search system including a microcomputer 10, a tuner / IF stage 12, an AFT detector 14, and a synchronous detector 16 so as to shorten a channel search time through a TV broadcast band search. 18), the PLL data, the clock, and the enable signal of the microcomputer 10 are divided into bands according to the key input of the band selection mode switch 18, and only the broadcasting channel of the corresponding selection band is memorized and then terminated. If there is no key input of the band selection mode switch 18, all bands are searched and memory is terminated after all broadcasting channels are memoryd.

Claims (1)

마이콤(10), 튜너/IF단(12), AFT검출기(4), 동기 검출기(16)를 포함하는 채널 서칭 시스템에 밴드선택 모드스위치(18)를 부가하여, 상기 밴드선택 모드스위치(18)의 키입력에 따라 마이콤(10)의 PLL데이터, 클럭, 인에이블 신호가 각 밴드별로 구분되어 해당 선택밴드의 방송채널만 메모리한후 종료시키고, 상기 밴드선택 모드스위치(18)의 키입력이 없으면 전 밴드를 서치하여 전방송 채널을 메모리 한후 종료시키는 TV밴드별 자동 서칭 방법.A band selection mode switch 18 is added to a channel search system including a microcomputer 10, a tuner / IF stage 12, an AFT detector 4, and a synchronization detector 16. The PLL data, clock, and enable signals of the microcomputer 10 are divided into bands according to the key input of the memory, and only after the broadcasting channel of the corresponding band is memorized, the signal is terminated. If there is no key input of the band selection mode switch 18, Automatic search method for each TV band that searches all bands and then ends all memory channels. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
