Abstract

영상 부호화/복호화 장치 및 방법이 개시된다. 본 발명의 실시예에 따른 영상 부호화/복호화 장치는, 매크로블록을 이용하여 분할된 서브블록을 예측하여 예측 서브블록을 생성하며, 서브블록과 예측 서브블록을 감산하여 잔여 서브블록을 생성하고, 잔여 서브블록을 상기 서브블록의 크기에 따라 선택되는 변환을 이용하여 변환하고 양자화하여 양자화된 변환 계수를 생성하며, 양자화된 변환 계수를 CABAC(Context-Adaptive Binary Arithmetic Coding)를 이용하여 부호화하는 경우, 사용된 매크로블록 및 분할된 서브블록에 따라 다른 컨텍스트 테이블을 사용하여 부호화된 영상 데이터를 생성하는 영상 부호화기; 및 CABAC를 이용하여 매크로블록 및 분할된 서브블록에 따라 다른 컨텍스트 테이블을 사용하여 부호화된 데이터를 복호화하여 분할 타입 정보, 움직임 정보, 변환 타입 정보 및 양자화된 변환 계수를 복원하며, 복원되는 변환 타입 정보에 의해 식별되는 변환을 이용하여 양자화된 변환 계수를 역 양자화 및 역 변환하여 잔여 서브블록을 복원하고, 복원되는 분할 타입 정보에 따라 식별되는 서브블록을 복원되는 움직임 정보를 이용하여 예측하여 예측 서브블록을 생성하며, 예측 서브블록과 잔여 서브블록을 가산하여 서브블록을 복원하고, 복원된 서브블록에 기초하여 매크로블록을 복원하는 영상 복호화기를 포함하는 것을 특징으로 한다.
