Abstract

본 발명은 동영상 부호화/복호화 장치 및 그를 위한 적응적 가중치를 사용하는 적응 중첩 블록 움직임 보상 방법 및 장치에 관한 것으로서, 본 발명에 따른 적응적 가중치를 사용하는 적응 중첩 블록 움직임 보상 장치는, 블록 움직임 추정 시의 잔여 신호 RBMC(x,y)를 산출하는 RBMC(x,y) 산출부; 인접한 블록의 움직임 벡터를 사용하여 움직임 보상된 블록과 현재 움직임 보상 블록 간의 화소 값의 차이 DN(x,y)를 구하는 DN(x,y) 산출부; RBMC(x,y) 및 DN(x,y)에 근거하여 적응적 중첩 블록 움직임 보상을 수행하기 위한 부가 정보를 갱신 및 설정하는 부가 정보 갱신/설정부; 및 상기 부가 정보에 근거하여 일정 단위의 각 화소에 대해 적응 중첩 블록 움직임 보상을 수행하되, RBMC(x,y)의 절대치가 상기 부가 정보보다 작거나 같을 경우 다음 화소로 진행하고, RBMC(x,y)의 절대치가 상기 부가 정보보다 클 경우 ROBMC(x,y)의 절대치 값이 RBMC(x,y)의 절대치 값보다 작아지도록 HN(x,y)의 부호를 정하여 ROBMC(x,y)를 산출하는 적응 중첩 블록 움직임 보상부를 포함하여 구성되어, 적은 부가 정보만으로 부호화해야 할 블록 경계 부의 잔여 신호 에너지를 크게 감소시킨다.
