Abstract

본 발명은 고선명 텔레비젼의 영상신호를 비디오카세트 레코더에 기록하고 재생하는 장치에 관한 것으로, 디지탈 데이타로 상호 인터페이스 하는 인터페이스 제어부와 데이타를 동기블럭단위로 묶고, 해제하는 포맷/디포맷부와 데이타의 오류를 검출하고 정정하는 데이타 정정부의 데이타를 기록하고 재생할때 변조 및 복조를 행하는 변/복조부와 데이타의 형태를 직렬 또는 병렬로 변환시키는 직/병렬 변환부를 포함한다. 따라서, 본 발명은 영상신호를 기록/재생할때 디지탈 데이타로 신호처리를 하므로써 회로를 간단히 하는 효과가 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for recording and reproducing a video signal of a high definition television to a video cassette recorder, wherein an interface control unit for interfacing with digital data, a format / deformatter unit for bundling and releasing data in units of synchronous blocks, and errors in data And a modulation / demodulation section for performing modulation and demodulation when recording and reproducing data, and a serial / parallel conversion section for converting data types in series or in parallel. Therefore, the present invention has the effect of simplifying the circuit by performing signal processing with digital data when recording / reproducing video signals.
