Abstract

L'invention porte sur un procédé (1000) de codage d'une séquence vidéo comprenant des ensembles d'images de référence (rps). Le procédé consiste à agencer (1001) les rps par ordre de transmission dans une structure de données, telle qu'un ensemble de paramètres de séquence (sps), à déterminer (1003) si une transmission de rps explicite est utilisée pour un rps d'une image courante de la séquence vidéo, et à coder (1004) des informations indiquant un rps compris dans la structure de données à utiliser pour prédire le rps de l'image courante, tel que delta_idx_minus1, seulement si une transmission de rps explicite est utilisée. Par transmission de delta_idx_minus1 seulement si une transmission de rps explicite est utilisée, et interprétation de delta_idx_minus1 comme étant égal à zéro autrement, un débit binaire réduit est obtenu. En outre, un procédé de décodage d'une séquence vidéo comprenant des rps, des programmes d'ordinateur et des produits programmes d'ordinateur correspondants, ainsi que des codeurs et des décodeurs correspondants sont décrits.
