Abstract

본 발명은 비디오 카세트 레코더의 제어신호 기록장치 및 재생장치에 관한 것으로, 성인용 비디오 테이프를 복사시에 CTL신호를 변조하여 기록하고, 재생시에 비밀 번호를 입력한 사람만이 복조된 CTL 신호를 이용하여 비디오 테이프를 시청할 수 있도록 하여 미성년자가 성인용 비디오 테이프를 시청할 수 없도록 할 수 있다.The present invention relates to a control signal recording device and a playback device of a video cassette recorder, wherein only a person who modulates and records a CTL signal when copying an adult video tape, and inputs a password at the time of reproduction uses a demodulated CTL signal. Video tapes can be viewed so minors cannot watch adult video tapes.
