Claims (1)
- 입력영상신호의 수직동기신호로부터 일정 구형과 신호를 발생시키고, 그 구형파신호를 지연부(6, 6)를 통해 블랭킹 기간에 속하도록 일정시간(t1,t2) 지연시키며, 텔레비젼 방식과 테이프 스피드모드에 따라 각기 다른 주파수를 출력하는 주파수발생기(8, 8′)의 출력신호를 상기 지연부(6, 6′)의 출력신호에 의해 가산기 (10)에 서 영상신호의 블랭킹 기간중에 가산하여 녹화되게하고, 재생시 재생영상신호로부터 수직동기신호를 분리하고 그 신호에 의해 일정시간 (t1,t2) 지연된 구형파신호를 발생시켜 스위칭회로(17, 17′)에서 상기 텔레비젼방식 및 테이프 스피드모드신호를 검출하며, 그 검출신호에 따라 주파수판별부(18, 18′)에서 추출된 일정전압이 색도채생계(2) 및 테이프속도서보부(25)에 인가되게 구성함을 특징으로 하는 브이씨알의 자동모드 절환회로.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
