Abstract: front page image
(EN)The method for deriving a temporal motion vector predictor according to the present invention comprises the steps of: selecting a reference picture for a current block; deciding a predictor block corresponding to a predetermined storage unit block, as a reference prediction unit for the current block, in the reference picture; and deriving the temporal motion vector predictor from motion information of the decided reference prediction unit. The present invention enhances image compression efficiency.
(FR)Le procédé destiné à dériver un prédicteur de vecteur de mouvement temporel selon la présente invention comprend les étapes consistant: à sélectionner une image de référence pour un bloc courant; à choisir un bloc prédicteur correspondant à un bloc d'unité de stockage prédéfini, comme unité de prédiction de référence pour le bloc courant, dans l'image de référence; et à dériver le prédicteur de vecteur de mouvement temporel des informations de mouvement de l'unité de prédiction de référence choisie. Cette invention permet d'améliorer l'efficacité de compression des images.
(KO)본 발명에 따른 시간적 움직임 벡터 예측자 도출 방법은, 현재 블록에 대한 참조 픽쳐를 선택하는 단계, 참조 픽쳐 내에서, 소정의 저장 단위 블록에 대응하는 예측 블록을, 현재 블록에 대한 참조 예측 유닛으로 결정하는 단계 및 결정된 참조 예측 유닛의 움직임 정보로부터 시간적 움직임 벡터 예측자를 도출하는 단계를 포함한다. 본 발명에 의하면 영상 압축 효율이 향상될 수 있다.
