Title (EN) METHOD AND APPARATUS FOR ENCODING/DECODING SCALABLE VIDEO SIGNAL
(FR) PROCÉDÉ ET APPAREIL DE CODAGE/DÉCODAGE D'UN SIGNAL VIDÉO ÉVOLUTIF
(KO) 스케일러블 비디오 신호 인코딩/디코딩 방법 및 장치
Abstract: front page image
(EN)A method for decoding a scalable video signal, according to the present invention, comprises: determining whether a corresponding picture in a lower layer is used as an inter-layer reference picture for a current picture in an upper layer, based on a time level identifier of the lower layer; and performing inter-layer prediction of the current picture using the corresponding picture, when the corresponding picture in the lower layer is used as the inter-layer reference picture for the current picture in the upper layer, wherein the inter-layer prediction is limitedly performed depending on tile alignment between the upper layer and the lower layer.
(FR)Selon l'invention, un procédé de décodage d'un signal vidéo évolutif consiste: à déterminer si une image correspondante dans une couche inférieure est utilisée comme image de référence intercouche pour une image courante présente dans une couche supérieure, sur la base d'un identifiant de niveau de temps de la couche inférieure; et à effectuer une prévision intercouche de l'image courante en utilisant l'image correspondante, lorsque l'image correspondante présente dans la couche inférieure est utilisée comme image de référence intercouche pour l'image courante présente dans la couche supérieure. La prédiction intercouche est réalisée de manière limitée en fonction de l'alignement en pavés entre la couche supérieure et la couche inférieure.
(KO)본 발명에 따른 스케일러블 비디오 신호 디코딩 방법은 하위 레이어의 시간레벨 식별자에 기초하여, 하위 레이어의 대응 픽쳐가 상위 레이어의 현재 픽쳐에 대한 인터레이어 참조 픽쳐로 이용되는지 여부를 결정하고, 하위 레이어의 대응 픽쳐가 상위 레이어의 현재 픽쳐의 인터레이어 참조 픽쳐로 이용되는 경우, 대응 픽쳐를 이용하여 현재 픽쳐의 레이어 간 예측을 수행하며, 레이어 간 예측은 상위 레이어와 하위 레이어 간의 타일 정렬 여부에 따라 제한적으로 수행되는 것을 특징으로 한다.
