Abstract

본 발명은 DVCR에 관한 것으로, 특히 테이프상의 트랙 스캐닝을 반복하여 선택적으로 복호화하는 방법으로 별도의 하드웨어의 추가없이 저속재생(slow play)을 실형할 수 있는 DVCR의 변속재생방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to DVCR, and more particularly, to a variable speed reproduction method of a DVCR capable of performing slow play without the addition of additional hardware by repeating and selectively decoding track scanning on a tape.

상기와 같은 본 발명의 DVCR의 변속 재생방법은 입력되는 1/n배속 재생신호에 의해 일정 단위의 정보기록 영역(1트랙)을 n번(n=2,3,4…)스캐닝하여 스캐닝해낸 정보의 처음 1/n구간의 정보만을 유효데이타로 출력하고, 배속정보에 따라 상기 유효데이타를 n-1배의 단위처리시간(1프레임 처리시간) 지연하여 복호화하여 출력하고 지연구간에서는 이전 화면의 데이터를 정지화상으로 출력하는 것을 반복하여 이루어진다.According to the variable speed reproduction method of the DVCR of the present invention as described above, information scanned by scanning the information recording area (1 track) of a predetermined unit n times (n = 2, 3, 4, ...) by an input 1 / n double speed reproduction signal is scanned. Only the first 1 / n section of the data is output as valid data, and the valid data is decoded and outputted by n-1 times the unit processing time (1 frame processing time) according to the double speed information, and the data of the previous screen is output in the delay section. Is repeated by outputting a still image.
