Abstract
Décodeur, système et procédé pour décoder des données multimédia au niveau d'un terminal en gérant l'énergie disponible pour le décodage comportant un décodeur (300, 500) des données multimédia, caractérisé en ce que ledit décodeur (300, 500) comporte au moins une chaîne de décodage « basse consommation » comprenant un module d'activation (305, 520) adapté à activer une première chaîne de décodage ou filtre de boucle basse consommation (509, 510, 511) et une chaîne d'interpolation basse consommation (535, 536, 537) en fonction d'au moins un paramètre représentatif de contraintes d'énergie utilisateur et/ou du terminal mobile et d'une ou de plusieurs métadonnées Md associées à une complexité de décodage et/ou à une énergie de décodage. Application à un terminal utilisant des standards H.264/AVC ou H.265/HEVC.
