Abstract

휘도 성분의 예측 단위에 대한 인트라 예측 모드를 이용하여 효율적으로 색차 성분의 예측 단위에 대한 인트라 예측 모드를 부호화, 복호화하는 방법 및 장치가 개시된다. 본 발명의 일 실시예에 따른 인트라 예측 모드 부호화 방법은, 휘도 성분의 예측 단위에 대한 인트라 예측 모드가 색차 성분의 예측 단위에 이용가능한 인트라 예측 모드 후보 그룹 중 소정 인트라 예측 모드들과 동일한 지 여부에 따라서, 휘도 성분의 예측 단위의 인트라 예측 모드와 중복되는 색차 성분의 예측 단위의 인트라 예측 모드를 인트라 예측 모드 후보 그룹으로부터 제외하거나 다른 인트라 예측 모드로 대체함으로써 색차 성분의 예측 단위의 인트라 예측 모드 후보 그룹을 재구성하고, 재구성된 인트라 예측 모드 후보 그룹을 이용하여 색차 성분의 예측 단위의 인트라 예측 모드를 부호화한다.
