Abstract

본 발명은 브이씨알의 영상 데이타 기록 회로에 관한 것으로, 종래 아날로그 방식은 장시간 기록모드의 경우 기록 트랙의 폭을 줄임으로써 화면의 열화를 동반하게 되고 디지탈 방식의 경우 트랙폭을 줄이면 데이터 자체의 복원이 어렵게 되는 문제점이 있었다.The present invention relates to an image data recording circuit of V-Cal. In the conventional analog method, the recording track is accompanied by deterioration of the screen by reducing the width of the recording track in the long time recording mode. There was a problem that became difficult.

이러한 점을 감안하여 본 발명에서는 영상압축 기술이 적용되지 않은 경우 임의의 프레임마다 영상을 선택기록하고 영상압축기술이 적용된 경우 I-frame 영상만을 선택하여 기록함으로써 기록데이타량을 줄여 장시간 기록을 가능하게 한다. 따라서, 동일 영상을 장시간 재생하는 경우와 같은 세미나 등에서 특수기능으로 사용할 수 있다.In view of this, in the present invention, when the image compression technique is not applied, the image is selectively recorded every arbitrary frame, and when the image compression technique is applied, only the I-frame image is selected and recorded to reduce the amount of recording data, thereby enabling long time recording. do. Therefore, it can be used as a special function in seminars, such as when playing the same video for a long time.
