Abstract: front page image
(EN) A method for decoding a multi-layer video comprises: acquiring, from a predetermined data unit header which corresponds to a first random access point picture included in a first layer video stream and has information on a second random access point picture included in a second layer video stream, first POC information for determining a first partial value of a POC of the second random access point picture which is set equal to a POC of the first random access point picture, and second POC information for a second partial value of the POC of the second random access point picture; and acquiring the POC of the second random access point picture by using the first POC information and the second POC information.
(FR) La présente invention a trait à un procédé permettant de décoder une vidéo multicouche, qui consiste : à acquérir, à partir d'un en-tête d'unité de données prédéfini qui correspond à une première image de point d'accès aléatoire incluse dans le flux vidéo de la première couche et qui contient des informations sur une deuxième image de point d'accès aléatoire incluse dans le flux vidéo de la deuxième couche, des premières informations de POC permettant de déterminer une première valeur partielle du POC de la deuxième image de point d'accès aléatoire, qui est fixé de manière à être égal au POC de la première image de point d'accès aléatoire, ainsi que des secondes informations de POC pour une seconde valeur partielle du POC de la deuxième image de point d'accès aléatoire ; et à acquérir le POC de la deuxième image de point d'accès aléatoire au moyen des premières et des secondes informations de POC.
(KO) 다계층 비디오 복호화 방법은 제 1 계층 영상 스트림에 포함된 제 1 랜덤 액세스 포인트 픽처와 대응되며, 제 2 계층 영상 스트림에 포함된 제 2 랜덤 액세스 포인트 픽처의 정보를 구비한 소정 데이터 단위 헤더로부터, 제 1 랜덤 액세스 포인트 픽처의 POC와 동일하게 설정된 상기 제 2 랜덤 액세스 포인트 픽처의 POC의 제 1 부분값을 결정하기 위한 제 1 POC 정보와 제 2 랜덤 액세스 포인트 픽처의 POC의 제 2 부분값에 대한 제 2 POC 정보를 획득하고, 제 1 POC 정보와 제 2 POC 정보를 이용하여 제 2 랜덤 액세스 포인트 픽처의 POC를 획득한다.
