Abstract

L'invention concerne un procédé de décodage, un terminal et un support d'informations lisible par ordinateur, le procédé comprenant : l'acquisition d'informations de paramètre de contenu cible concernant un fichier multimédia à décoder, les informations de paramètre de contenu cible étant des informations de format vidéo concernant le fichier vidéo à décoder ; l'interrogation, dans au moins un mode de décodage prédéfini, d'un mode de décodage cible correspondant aux informations de paramètre de contenu cible ; la réalisation d'un traitement de décodage sur le fichier multimédia à décoder au moyen du mode de décodage cible ; et l'acquisition du fichier multimédia décodé après la réalisation du traitement de décodage. Au moyen de la présente invention, un mode de décodage cible correspondant peut être acquis en fonction des informations de paramètre de contenu cible concernant un fichier multimédia à décoder de façon à décoder le fichier multimédia à décoder, ce qui permet d'augmenter le taux de réussite du décodage.
