Abstract

본 발명은 영상신호의 수직블랭킹부에 중첩하는 파형데이터를 기록하기 위한 전용영역을 구비한 디지틀 VCR등의 영상신호기록재생장치에 관한 것이며, 그 구성에 있어서, 중첩하는 파형의 샘플을 4레벨로 표시하고 수직블랭킹부의 1수평기간중에 50개미만의 샘플점을 가지고, 또 수직블랭킹부의 임의의 수평기간에 파형을 중첩할 수 있다. 테이프상의 1트랙에는, 예를들면 1수평기간에 중첩하는 48샘플의 파형데이터 12바이트와, 이 파형중첩에 관한 부가정보용으로 1바이트의 합께 13바이 트를 기록한다 이 결과 중첩하는 파형데이타의 1트랙당 총 데이터량에 차지하는 비율을 0.1%정도로 하고 있다. 이 기능에 의해 테이프소비량을 증가시키지 않고, 컴포넌트입출력에 있어서의 휘도신호와 색신호의 지연시간조정등을 가능하게 하는 것을 특징으로한 것이다.The present invention relates to a video signal recording and reproducing apparatus such as a digital VCR having a dedicated area for recording waveform data superimposed on a vertical blanking portion of a video signal. It is possible to display and have a sample point of less than 50 in one horizontal period of the vertical blanking unit, and to superimpose the waveform in any horizontal period of the vertical blanking unit. In one track on the tape, for example, 48 samples of waveform data 12 bytes overlapping in one horizontal period and 13 bytes of a byte together for additional information on the waveform overlap are recorded. The percentage of total data per track is about 0.1%. This function makes it possible to adjust the delay time of the luminance signal and the color signal in component input / output without increasing the tape consumption.
