상술한 바와 같이 화면상에 움직이는 영상이 없으면 기록매체에 영상데이터를 기록하지 않고 움직이는 영상이 넓게 분포되어 있으면 테이프에 기록하고, 화면의 한 부분에 집중적으로 발생하면 필요한 부분만을 디스크에 기록함으로써, 기록매체의 사용 효율을 높일 수 있다.As described above, if there is no moving image on the screen, the moving image is recorded on the tape if the moving image is widely distributed without recording the image data on the recording medium. If a moving image is concentrated on one part of the screen, The use efficiency of the medium can be increased.
