Abstract: front page image
(EN)An interlayer prediction method according to the present invention comprises: a step of determining the position of a reference criteria sample corresponding to an enhancement criteria sample in a reference layer on the basis of the position of an enhancement criteria sample that belongs to an enhancement layer; a step of determining at least one reference layer block in the reference layer on the basis of the position of the reference criteria sample; and a step of predicting the current block that belongs to the enhancement layer on the basis of the movement information of said at least one reference layer block.
(FR)La présente invention concerne un procédé de prédiction intercouche qui comprend : une étape consistant à déterminer la position d'un échantillon de critères de référence correspondant à un échantillon de critères d'amélioration dans une couche de référence sur la base de la position d'un échantillon de critères d'amélioration qui appartient à une couche d'amélioration; une étape consistant à déterminer au moins un bloc de couche de référence dans la couche de référence sur la base de la position de l'échantillon de critères de référence; et une étape consistant à prédire le bloc courant qui appartient à la couche d'amélioration sur la base des informations de déplacement dudit ou desdits blocs de couche de référence.
(KO)본 발명에 따른 인터 레이어 예측 방법은, 인핸스먼트 레이어에 속한 인핸스먼트 기준 샘플의 위치를 기반으로, 참조 레이어 내에서 인핸스먼트 기준 샘플에 대응되는 참조 기준 샘플의 위치를 결정하는 단계, 참조 기준 샘플의 위치를 기반으로, 참조 레이어에서 적어도 하나의 참조 레이어 블록을 결정하는 단계 및 적어도 하나의 참조 레이어 블록의 움직임 정보를 기반으로, 인핸스먼트 레이어에 속한 현재 블록에 대해 예측을 수행하는 단계를 포함한다.
