Abstract

본 발명은 감시용 디지탈 영상 시스템의 기록 및 재생 방법에 관한 것으로서, 더욱 상세하게는 짝수 필드로부터 기록이 시작되는 경우 재생에서의 프레임 구성 방법에 관한 것이다.The present invention relates to a method for recording and reproducing a digital video system for surveillance, and more particularly, to a method for configuring a frame in reproduction when recording starts from an even field.

본 발명의 목적을 위하여 시작 필드가 짝수 필드부터 기록되고 있는가를 판별하는 짝수 필드 판별 단계, 짝수 필드 판별 단계에서 짝수 필드로부터 기록되고 있으면 짝수 필드 시작 신호를 저장해서 데이타를 기록하는 짝수 필드 시작 신호 기억 단계, 독출된 데이타가 짝수 필드로부터 시작해서 기록되어 있는 가를 판단하는 짝수 필드 판별 단계, 짝수 필드 판별 단계에서 짝수 필드로 시작했으면 홀수 필드, 및 짝수 필드로 프레임을 재구성하여 재생하는 프레임 재구성 처리 단계를 포함하는 것을 특징으로 한다.Even field determination step for determining whether the start field is recorded from the even field for the purpose of the present invention, and even field start signal storage step for storing data by storing the even field start signal if the even field is recorded from the even field in the even field determination step. And an even field determination step of determining whether the read data is recorded starting from the even field, an odd field if the even field is started in the even field determination step, and a frame reconstruction processing step of reconstructing and playing the frame with the even field. Characterized in that.

상술한 바와 같이 본 발명에 의하면, 감시용 디지탈 영상 시스템의 기록 및 재생에 있어서, 짝수 필드와 홀수 필드를 구분하지 않고 프레임을 구성할 수 있는 잇점이 있다.As described above, according to the present invention, in recording and reproducing a surveillance digital video system, there is an advantage that a frame can be formed without distinguishing even and odd fields.
