Abstract

영상의 복호화 방법은 수신된 비트 스트림을 엔트로피 복호화하여 잔여값을 역양자화 및 역변환하여 잔여값을 복원하는 단계와, 비대칭 파티션 분할 및 기하학적 파티션 분할 방법 중 적어도 하나를 적용하여 분할된 예측 유닛에 대하여 복수의 예측 모드 중 하나를 선택적으로 사용하여 화면내 예측 부호화를 수행하여 예측 유닛을 생성하는 단계와, 상기 예측 유닛에 상기 잔여값을 더하여 영상을 복원하는 단계를 포함한다. 비대칭 파티션닝 및/또는 기하학적 파티션닝에 대하여 화면내 예측을 적용하여 HD급 이상의 고해상도 영상의 부호화 효율을 향상시킬 수 있다.
