Abstract

본 발명은 종래의 영상기록 장치에서 두 헤드로 영상신호를 기록/재생하던 방식에서 한 헤드만으로도 영상신호의 기록/재생이 가능하도록 한 복합영상신호 처리에 관한 것으로, 입력영상신호를 압축 처리하여 2라인을 1라인으로 줄임으로서 기존의 신호기록 방식에서 기록매체의 1트랙에 1필드의 신호만을 기록하던 방식에서 1트랙에 2필드(1프레임)의 신호를 기록하게 하여 기록매체에 2배의 시간동안 신호의 기록이 가능하게 된다.The present invention relates to a composite video signal processing that enables recording / playback of a video signal with only one head in a method of recording / reproducing video signals with two heads in a conventional video recording apparatus. By reducing the line to one line, in the conventional signal recording method, only one field signal is recorded on one track of the recording medium, and two fields (one frame) are recorded on one track, thereby doubling the time on the recording medium. Recording of the signal is enabled.
