Abstract

본 발명은 비디오신호를 비디오테이프에 기록중 녹화중지모드로 절환하였을때 녹화시간에서 부터 녹화중지까지 구간동안 테이프에 비디오신호가 양호하게 기록되었는지를 판별하는 비디오신호 기록유무판별장치 및 방법에 관한 것이다. 종래 비디오장치의 경우 녹화상태를 확인하기 위해서 스톱모드로 절환후 되돌리기 또는 되감기 모드로 테이프를 후진시킨 후 모니터 수단을 통해 화면으로 확인해야 하므로 조작이 복잡하고 불편하다. 본 발명은 비디오신호의 기록유무를 판별하는 수단과 경보발생수단을 부가시켜 시스템적으로 제어하는 비디오신호가 테이프에 기록되어 있지 않으면 경보발생수단을 통하여 녹화불량을 알려줌으로써 녹화상태를 신속하고도 정확하게 알 수 있으므로 VCR이나 캠코더 등의 비디오장치에 효과적으로 사용될 수 있다.The present invention relates to a video signal recording discrimination apparatus and method for discriminating whether or not a video signal is well recorded on a tape during a period from a recording time to a recording stop when switching a video signal to a recording stop mode during recording on a video tape. . In the case of the conventional video device, the operation is complicated and inconvenient because it is necessary to check the screen through the monitor means after reversing the tape in the rewind or rewind mode after switching to the stop mode to check the recording state. According to the present invention, if a video signal controlled by adding a means for determining whether a video signal is recorded and an alarm generating means is not recorded on a tape, the recording state is notified quickly and accurately by notifying the recording failure through the alarm generating means. As it can be seen, it can be effectively used for video devices such as VCRs or camcorders.
