Abstract

부호화 단위에 기반한 디블록킹 필터링을 수행하는 비디오 부호화 방식이 개시된다. 본 발명에 따르면 최대 부호화 단위의 공간적 분할 횟수를 나타내는 심도에 따라 계층적으로 구성되는 부호화 단위들과 부호화 단위의 예측 및 변환을 위한 예측 단위들 및 변환 단위들 중 적어도 하나의 데이터 단위에 기초하여 디블록킹 필터링을 수행할 필터링 경계를 결정하고, 결정된 필터링 경계를 기준으로 인접한 픽셀들이 속하는 부호화 단위의 예측 모드 및 필터링 경계에 인접한 픽셀들의 변환 계수값들에 기초하여 필터링 경계에서의 필터링 강도를 결정하며, 결정된 필터링 강도에 기초하여 디블록킹 필터링을 수행한다.
