Title
(KO) 시간적 블록 벡터 예측을 갖는 인트라 블록 카피 코딩
Abstract
(KO)
본원에서 개시되는 실시형태는, 병합 모드의 예측 유닛 레벨에서 IntraBC 플래그를 명시적으로 통합하는 것에 의해 종래의 비디오 코딩 기술을 향상시키도록 동작한다. 이 플래그는 블록 벡터(block vector; BV) 후보 및 모션 벡터(motion vector; MV) 후보의 별개의 선택을 허용한다. 구체적으로는, IntraBC 플래그의 명시적 시그널링은, 특정한 예측 유닛이 BV를 사용할 것인지 또는 MV를 사용할 것인지의 여부에 대한 정보를 제공한다. IntraBC 플래그가 설정되면, 후보 리스트는 공간적 및 시간적 이웃 BV만을 사용하여 구성된다. IntraBC 플래그가 설정되지 않으면, 후보 리스트는 공간적 및 시간적 이웃 MV만을 사용하여 구성된다. 그 다음, 후보 BV 또는 MV의 리스트를 가리키는 인덱스가 코딩된다. 본원에서 개시되는 추가 실시형태는, 통합된 IntraBC 및 인터 프레임워크에서 BV-MV 양예측을 사용한다.
