Abstract

스킵 모드를 이용한 영상 복호화 방법 및 이러한 방법을 사용하는 장치가 개시되어 있다. 영상 복호화 방법은 잔차 블록 정보의 부호화 여부를 나타내는 소정의 정보를 기초로 예측 대상 블록의 잔차 블록 정보가 존재하는지 여부를 판단하는 단계와 잔차 블록 정보가 존재하는 경우 상기 예측 대상 블록의 화면 내 예측값 및 잔차 블록 정보를 기초로 상기 예측 대상 블록을 복원하는 단계를 포함할 수 있다. 따라서, 화면의 유사도에 따라 잔차 정보 블록이 필요한 예측 대상 블록에 대해서만 화면의 잔차 정보를 부호화 및 복호화를 수행하여 부호화 및 복호화 효율을 증가시킬 수 있다.
