Abstract
본 발명은 녹화전이나 녹화중에 영상신호가 없거나 약할 시 예약녹화 및 일반녹화 동작을 자동으로 중지시킴으로써, 방송국 사정이나 기상 상태 또는 다른 어떤 원인에 의해 신호가 없는 화면이 불필요하게 고스란히 테이프에 녹화되는 것을 방지할 수 있게 하여 VCR의 헤드와 테이프의 마모를 줄일 수 있는 VCR의 녹화제어방법에 관한 것인 바, 그 특징은 녹화모드가 설정되는 경우 영상신호를 검색하여 동기신호의 유/무를 판별하는 제1단계와, 상기 제1단계의 동기신호 유/무에 따라 동기시호가 있는 경우 이미 설정된 녹화 시간을 체크하면서 정상적으로 녹화동작을 수행하거나 동기신호가 없는 경우 다시 동기신호가 검출될때까지 녹화동작을 일시 정지시키는 제2단게로 이루어짐에 있다.The present invention automatically stops the scheduled recording and general recording operations when there is no or weak video signal before or during recording, so that a signal-free screen is unnecessarily recorded on the tape unnecessarily due to broadcasting station conditions, weather conditions or any other cause. The present invention relates to a recording control method of a VCR, which can reduce the wear of a head and a tape of the VCR. The feature of the present invention is to determine whether a synchronization signal is present or not by searching an image signal when the recording mode is set. If there is a synchronization signal according to the first and second synchronization signals in step 1 and the synchronization signal, the recording operation is normally performed while checking the preset recording time, or if there is no synchronization signal, the recording operation is paused until the synchronization signal is detected again. It consists of a second stage to stop.
