Abstract
Description
Claims (1)
- 프레임/필드 단위로 입력되는 영상 신호의 움직임 벡터를 검출하여 부호화하는 방법에 있어서, 상기 프레임/필드의 영상 신호의 움직임 벡터를 상기 프레임/필드내 블록별로 검출하는 단계와; 상기 검출된 움직임 벡터가 이산적인 프레임/필드별 블록간의 움직임 벡터가 이산(랜덤)적이면, 상기 프레임/필드별 영상 신호를 인트라 모드로 부호화하는 단계와, 상기 프레임/필드별 블록간의 움직임 벡터가 0이면 상기 프레임/필드별 영상 신호를 인터 모드로 부호화하는 단계와; 상기 프레임/필드별 블록간의 움직임 벡터가 일정한 방향으로 일정한 값을 가지는 경우에는 상기 움직임 벡터에 해당하는 이전 프레임/필드 위치의 화소들을 이용하여 인터 모드로 부호화하는 단계를 구비하는 예측 부호화 방법.
