Abstract:
(EN) The present invention relates to 3D video coding device and method. A decoding method, according to the present invention, provides a 3D video decoding method. A decoding method comprises the steps of: obtaining a disparity value on the basis of a reference view and a predetermined value; deriving movement information of a current block in a depth picture on the basis of the disparity value; and generating a prediction sample of the current block on the basis of the movement information, wherein the reference view is a view of a reference picture in a reference picture list. According to the present invention, even when a base view cannot be accessed, a disparity vector can be derived on the basis of an available reference view index in a decoded picture buffer (DPB), and coding efficiency can be enhanced.
(FR) La présente invention porte sur un dispositif et un procédé de codage vidéo en 3D. Un procédé de décodage, selon la présente invention, consiste en un procédé de décodage vidéo en 3D. Les étapes d’un tel procédé de décodage consistent : à obtenir une valeur de disparité sur la base d’une vue de référence et d’une valeur préétablie ; à déduire des informations de mouvement d’un bloc actuel dans une image de profondeur sur la base de la valeur de disparité ; et à générer un échantillon de prédiction du bloc actuel sur la base des informations de mouvement, la vue de référence étant une vue d’une image de référence dans une liste d’images de référence. Selon la présente invention, même s’il n’est pas possible d’accéder à une vue de base, un vecteur de disparité peut être déduit sur la base d’un indice de vue de référence disponible dans un tampon d’images décodées (DPB), et l’efficacité de codage peut être renforcée.
(KO) 본 발명은 3D 비디오를 코딩하는 장치 및 방법에 관한 것으로, 본 발명에 따른 디코딩 방법은 D 비디오 디코딩 방법을 제공한다. 상기 디코딩 방법은 참조 뷰(view) 및 소정의 값을 기반으로 디스패리티 값을 획득하는 단계, 상기 디스패리티 값을 기반으로 뎁스 픽처 내 현재 블록의 움직임 정보를 도출하는 단계, 및 상기 움직임 정보를 기반으로 상기 현재 블록의 예측 샘플을 생성하는 단계를 포함하되, 상기 참조 뷰는 참조 픽처 리스트 내의 참조 픽처의 뷰임을 특징으로 한다. 본 발명에 따르면, 베이스 뷰(base view)를 엑세스하지 못하는 경우에도, DPB(decoded picture buffer) 내의 가용한 참조 뷰 인덱스에 기반하여 디스패리티 벡터를 유도할 수 있고, 코딩 효율을 향상시킬 수 있다.
