Description

비데오 테이프 레코오더의 픽처 서어치시 모우드 절환방법How to switch the mode of picture search in video tape recorder

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명의 회로도.1 is a circuit diagram of the present invention.

제2도는 비데오 테이프 영상 신호가 기록된 각 트랙의 상태도.2 is a state diagram of each track in which a video tape video signal is recorded.

제3도는 7배속시 본 발명의 카운터 출력상태도.3 is a counter output state of the present invention at 7 times speed.

제4도는 7배속시 장동간 모우드에서 정속 모우드로 전환될 경우 본 발명 회로도의 각부 파형도.4 is a waveform diagram of each part of the circuit diagram of the present invention when switching from a long drive mode to a constant speed mode at 7 times speed.

Claims (1)

노이즈 발생회로(10) 드롭아우트검파부(2)에서 노이즈 발생시 1H 지연된 화상을 출력시키기 위하여 드롭아우트펄스를 발생시키는 방법에 있어서, 헤드스위칭 펄스(HS)의 1주기동안 인가되는 드롭아우트 펄스를 평활회로(5)와 쉬미트리거(6)를 통하여 카운터(7)로 계수하게 한 후 랫치부(20)에 저장된 출력을 논리적으로 제어 연산시켜 반전용 플립플롭(FF4)을 구동시키는 비데오 테이프 레코오더의 픽처 서어치시 모우드 절환방법.In the noise generating circuit (10), the dropout detection unit (2) generates dropout pulses to output an image delayed by 1H when noise is generated, wherein the dropout pulses applied during one period of the head switching pulse (HS) are smoothed. A video tape recorder for driving the flip flip-flop (FF 4 ) by causing the counter 7 to count through the circuit 5 and the shimmer trigger 6, and then logically controlling the output stored in the latch unit 20. How to switch the mode during picture search. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
