Abstract

본 발명의 목적은 디지탈 VCR의 아날로그 출력단자를 사용하여 더빙을 수행하는 때에, 자료의 저작권을 확실하게 보호함과 동시에. 자료의 카피세대 등의 정보도 알도록 하는 것이다.
구성에 있어서, 디지탈VCR(1)에서 재생된 시스템 자료는 시스템 자료처리회로(6)에 공급된다. 시스템 자료처리회로(6)는 공급된 자료에 기초하여 CP신호 발생기(10)나 VBID발생기(11)에 제어신호를 공급한다. CP신호나 VBID가 기록단축 디지탈 VCR(20) 및 아날로그 VCR(40)에 공급된다.디지탈 VCR(20)의 VBID검출기(22)에서는 VBID가 검출된다.또한 아날로그 VCR(40)에서는 아날로그 비디오 출력중에 CP신호가 있는 경우, AGC회로(41)가 교란된다.
