Abstract

본 발명은 다중재생 모드를 갖는 DVCR의 재생방법에 관한 것으로 재생시 임의의 구간내에서 발생하는 에러의 갯수를 이용하여 기록모드에 해당하는 클럭신호를 발생시켜 여러가지 기록모드에 있어서 상기 기록모드에 해당하는 재생모드를 선택하는데 적당한 다중재생 모드를 갖는 DVCR의 재생방법을 제공하기 위함이다.The present invention relates to a reproducing method of a DVCR having a multiple reproducing mode, wherein a clock signal corresponding to a recording mode is generated by using the number of errors occurring in an arbitrary section during reproducing, and corresponds to the recording mode in various recording modes. To provide a reproduction method of a DVCR having a multiple reproduction mode suitable for selecting a reproduction mode.

이를 위한 본 발명의 다중재생 모드를 갖는 DVCR의 재생방법은 기록테이프의 종류를 판단하는 제1단계, 임의의 동작모드로서 재생동작을 시작하고, 시스콘의 제어신호에 의해 현재의 에러 카운트 값과 스레스홀드값을 비교하는 제2단계, 상기 비교결과에 따라 현재의 동작모드를 유지하거나 전압제어 발진기를 제어하여 기록모드에 해당하는 클럭신호를 발생시켜 기록모드와 동일한 재생모드를 변환, 선택하는 제3단계를 포함하여 이루어짐을 특징으로 한다.The DVCR playback method having a multiple playback mode according to the present invention has a first step of determining the type of recording tape, and starts the playback operation as an arbitrary operation mode, and the current error count value is controlled by the control signal of the scissor. In the second step of comparing the threshold value, according to the comparison result, the current operation mode is maintained or a voltage controlled oscillator is controlled to generate a clock signal corresponding to the recording mode, thereby converting and selecting the same playback mode as the recording mode. Characterized in that it comprises a third step.
