Abstract

본 발명은 움직임벡터 부호화/복호화 방법 및 그 장치에 관한 것으로서, 현재 움직임벡터에 대한 후보 움직임벡터 집합을 선정하고; 후보 움직임벡터 집합에서 예측 움직임벡터를 선택하고; 예측 움직임벡터가 복호화 장치에서 예측가능한지를 판단하고; 예측가능으로 판단된 경우, 예측 움직임벡터 및 예측가능을 지시하는 움직임벡터 예측모드를 이용하여 현재 움직임벡터를 부호화하고; 및 예측 불가능으로 판단된 경우, 디폴트 예측 움직임벡터 및 예측 불가능을 지시하는 움직임벡터 예측모드를 이용하여 현재 움직임벡터를 부호화하는 것을 특징으로 한다. 본 발명에 의하면, 현재 움직임벡터에 대한 예측 움직임벡터를 직접 복호화 장치로 알리지 않고, 예측 움직임벡터를 찾을 수 있도록 정보를 주거나 찾기 위한 소정의 함수를 공유함으로써, 움직임벡터 예측모드에 따라 예측 움직임벡터를 선택하여 현재 움직임벡터를 부호화 및/또는 복호화하고, 움직임벡터 예측모드를 복호화 장치에 전송함으로써 부호화 비트량 감소, 움직임 예측 성능 및 움직임 보상 성능을 향상시키는 효과가 있다.
