Abstract
본 발명은 테이프에 기록된 콘트롤 펄스 및 캡스턴 모터의 구동 시간 펄스(I-LMT)를 이용하여 비데오 카세트 레코더의 슬로우 모드시 배속 재생 모드를 변경하기 위한 것으로서, 구동 시간 펄스(I-LMT)와 콘트를 펄스의 상승 에지 사이의 경과 시간에 따라 테이프의 배속 재생 모드를 판단하고, 이에 따라 비데오 카세트 레코더의 배속 재생 모드를 설정한다.The present invention is for changing the double speed reproduction mode in a slow mode of a video cassette recorder by using a control pulse recorded on a tape and a driving time pulse (I-LMT) of a capstan motor. The driving time pulse (I-LMT) Determines the double speed playback mode of the tape according to the elapsed time between the rising edge of the pulse and sets the double speed playback mode of the video cassette recorder accordingly.
