Abstract

본 발명은 시청자가 외부 AV(Audio Video)기기, 예컨대 VCR(Video Cassette Recoder)로부터 입력되는 AV 신호를 시청하면서 자동채널 검색기능을 실행할 수 있도록 된 TV용 자동 채널검색시스템에 관한 것으로서, 튜너의 국부발진회로의 발진주파수를 점차로 증가시킴과 더불어 자동 미조전압의 레벨을 근거로 전체 방송채널을 검색하는 자동채널 검색수단을 구비한 TV에 있어서, 외부 AV기기로부터의 음성 및 영상신호와 내부적으로 검파된 방송신호의 음성 및 영상신호를 선택적으로 입력하는 스위칭수단과, 상기 자동채널 검색수단을 작동시키기 위한 선택수단, 상기 스위칭수단에 의해 외부 AV기기로부터의 음성 및 영상신호가 선택입력되는 상태에서 상기 선택수단에 의한 선택에 따라 상기 자동채널 검색수단을 작동제어하는 제어수단 및, 상기 자동채널 검색수단에 의해 검색된 채널정보를 상기 AV기기로부터 입력되는 영상신호와 함께 CRT상에 출력시키는 채널정보 출력수단을 포함하여 구성된 것을 특징으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic channel search system for a TV, which enables a viewer to execute an automatic channel search function while watching an AV signal input from an external audio video (AV) device, such as a video cassette recorder (VCR). A TV having an automatic channel search means for gradually increasing the oscillation frequency of an oscillation circuit and searching an entire broadcasting channel based on the level of an automatic unbalanced voltage, the TV being detected internally with an audio and video signal from an external AV device. Switching means for selectively inputting audio and video signals of a broadcast signal, selection means for operating the automatic channel searching means, and selection in a state in which audio and video signals from an external AV device are input by the switching means. Control means for operating and controlling said automatic channel searching means in accordance with selection by said means, and said automatic channel searching number The channel information detected by the channel, including the information output means for outputting to the CRT with the image signal inputted from the AV device is characterized in that configured.
