Abstract

본 발명은 송신측 부호기과 동일하지 않은 압축기법이 수신축복호기에서 채용되어 있을 경우에도, 이를 수용하여 영상데이타를 부호화하는 부호화기에 관한 것으로, 이를 해결하기 위하여 현재 프레임(n)과 이전 프레임(n-1)간에 의거하여 예측된 프레임(A)을 구현하고, 상기 현재 프레임(n)과 앞선 프레임(n+1)에 의거하여 예측된 프레임(B)을 구현하며, 이로부터 각각의 프레임(A)(B)을 선택적으로 제공하는 움직임 예측부와, 이 예측된 프레임(A)을 저장 및 복원하는 제1 프레임 메모리 이로부터 복원된 현재 및 이전 프레임간의 예측된 프레임(A)과 예측된 프레임(B)에 의거하여 간축된 프레임을 출력하는 제1움직임 예측부, 제1 움직임 예측부에 의해 예측된 움직임 변위정보를 가변길이 부호화는 제1 VLC로 구성함으로써 수신축 복호기와 송신측 부호기간의 다른 압측기법이 사용될 경우에도 효율적인 부호화가 가능한 효과가 있다.The present invention relates to an encoder which encodes image data by receiving a compression method which is not identical to the transmitting encoder, even if the receiving encoder is adopted. In order to solve this problem, the present frame (n) and the previous frame (n−) are solved. Implement the predicted frame (A) based on 1), and implement the predicted frame (B) based on the current frame (n) and the preceding frame (n + 1), from which each frame (A) A motion predictor for selectively providing (B) and a first frame memory for storing and restoring the predicted frame A, and the predicted frame A and the predicted frame B between the current and previous frames recovered from the first frame memory. The first motion predictor outputs the reduced frame based on the < RTI ID = 0.0 >), and the variable length coding comprises the first VLC for the motion displacement information predicted by the first motion predictor. ≪ / RTI > Even when other compression techniques are used, efficient coding can be achieved.
