Abstract

본 발명은 녹화모드선택시 고속전진재생동작을 수행하면서 영상동기신호를 검출하여 영상동기신호가 검출되었을 경우에는 소정의 지연주행시간을 거친 후 바로 녹화동작을 개시하고, 또한 영상동기신호가 검출되지 않았을 경우에는 고속후진재생동작을 수행하면서 재차 영상동기신호를 검출하여 영상동기신호가 검출되었을 경우에는 소정의 지연주행시간을 거친 후 녹화동작을 개시하며, 영상동기신호가 검출되지 않았을 경우에는 되감기 동작후 녹화동작을 개시하도록 된 테이프의 무녹화부분 검출/녹화기능을 갓춘 비디오카세트레코더를 제공한다.According to the present invention, when the video synchronization signal is detected while performing the fast forward playback operation when the recording mode is selected, if the video synchronization signal is detected, the recording operation starts immediately after a predetermined delay driving time, and the video synchronization signal is not detected. If not, the video sync signal is detected again while the fast reverse play operation is performed. If the video sync signal is detected, the recording operation starts after a predetermined delay driving time. If the video sync signal is not detected, the video rewind operation is performed. There is provided a video cassette recorder equipped with a non-recorded portion detection / recording function of a tape which is to start a recording operation.

이를 위해 본 발명은 키입력부(90)로부터의 재생 및 녹화기능입력신호에 따른 마이콤(60)의 제어에 의해 비디오테이프에 저장된 데이터를 독출/증폭하고 영상처리부(70)에 의해 영상처리하여 도시되지 않은 모니터 및 스피커로 출력하거나 또는 튜너로부터의 텔레비전영상/음성신호나 외부기기집속단자(80)에서 입력되는 영상 신호를 소정의 처리과정을 거쳐 비디오테이프에 녹화하는 비디오카세트레코더(VCR)에 있어서, 상기 마이콤(60)에는 상기 녹화모드시에 테이프에 저장된 데이터의 동기신호의 유/무에 따라 상기 테이프의 무녹화부분을 자동검출한 후 상기 무녹화부분에서부터 녹화동작을 개시하는 무녹화부분검출/녹화기능이 더 구비되어 있다.To this end, the present invention is not illustrated by reading / amplifying data stored in the videotape by controlling the microcomputer 60 according to the playback and recording function input signal from the key input unit 90 and image processing by the image processing unit 70. In a video cassette recorder (VCR) for outputting to a monitor and a speaker, or for recording a video / audio signal from a tuner or a video signal input from an external device focusing terminal 80 through a predetermined process, on a video tape. The microcomputer 60 automatically detects the non-recorded portion of the tape in accordance with the presence / absence of the synchronization signal of the data stored in the tape in the recording mode, and then detects the non-recorded portion to start the recording operation from the non-recorded portion. It is equipped with a recording function.
