Abstract

비디오테이프 레코더의 화면 서치시 무신호부분에서 텔레비젼 방송 또는 블루화면을 제공하기 위한 장치가 기술되는바, 이는 비디오테이프의 서치모드시에 비디오 신호의 포락선을 검출하여 포락선이 검출되지 않을 경우 모니터에 텔레비젼 방송이나 블루화면을 약 5초간 표시토록 구성된 것이다.An apparatus for providing a television broadcast or a blue screen in a no-signal portion during screen search of a videotape recorder is described, which detects an envelope of a video signal in the search mode of a videotape and monitors the television on a monitor when no envelope is detected. It is configured to display broadcast or blue screen for about 5 seconds.
