Zusammenfassung:PURPOSE: A device for recording and reproducing video of a D-VCR(Digital-Video Cassette Recorder) is provided to decide a bit rate of inputted digital data and discriminate a tape kind according to a recordable wavelength of a videotape, so as to vary a recording or reproducing speed and automatically control a recording mode or a reproducing mode to an SP or LP mode. CONSTITUTION: An IRD(Integrated Receiver Decoder(11) receives a broadcasting signal from a digital signal source for processing. In a VCR(Video Cassette Recorder)(19), an input/output unit(12) inputs a received digital signal, and outputs a reproduced digital signal. A signal processor(13) processes the inputted digital signal appropriately for a recording format or the reproduced digital signal appropriately for a reproducing format for outputting, and detects a bit rate of the digital signal, to output a recording or reproducing control signal. A tape kind detector(14) detects a tape kind according to a recordable wavelength of a videotape. A controller(15) receives the tape kind detection signal to discriminate a tape kind, and receives the control signal from the signal processor(13) to control a recording or reproducing speed. A drum(16) drives a rotative head drum. A head(17) records the recording signal outputted in the signal processor(13) in the videotape, or reproduces a recorded video signal to be inputted to the signal processor(13). And a tape transferring unit(18) transfers the videotape. 본 발명은 디지탈 영상 신호원으로부터 제공되는 디지탈 영상신호를 자기 기록매체, 특히 비디오 테이프에 기록하고 또 재생하는 장치에 관한 것이다. 특히, 본 발명은 테이프의 기록 가능한 파장에 따르는 종류를 판단하는 수단과, 디지탈 방송신호원으로부터 제공되는 데이타 전송율을 판단하는 수단과, 상기의 테이프 종류와 전송율에 따라 회전 헤드드럼과 테이프 속도를 결정하여 제어하는 수단을 구비함으로써, 입력된 디지탈 데이타 전송율(bit rate)을 판정하고 또 비디오 테이프의 기록 가능한 파장에 따르는 테이프 종류를 판별하여 기록 또는 재생속도를 가변속함과 함께 기록모드나 재생모드를 프로그램의 데이타 분량에 대응하여 노말 테이프-SP 또는 노말 테이프-LP로 자동 제어할 수 있도록 한 디지탈 브이씨알(D-VCR)의 영상 기록 재생 장치이다.
