Abstract

La présente invention concerne une technique de codage vidéo ayant une compensation de mouvement au sein d'une fine couche d'enrichissement codée modulaire et échelonnable. Dans un mode de réalisation, le codage vidéo comporte une couche d'enrichissement basée sur une prédiction à double boucle comprenant des trames de couches d'enrichissement I et P non basées sur la prédiction de mouvement et des trames de couches d'enrichissement B basées sur de la prédiction de mouvement. On calcule les trames de couches d'enrichissement B basées sur la prédiction de mouvement en utilisant: 1) la prédiction de mouvement à partir des deux résidus de trames différentiels de I et P ou de P et P adjacents dans le temps, et 2) les résidus différentiels de trames B obtenus par la soustraction des résidus de trames de couches de base B décodées des résidus de trames de couches de base B d'origine. Dans un deuxième mode de réalisation, la couche d'enrichissement comporte en outre des trames de couches d'enrichissement P basée sur la prédiction. On calcule les trames de couches d'enrichissement P en utilisant: 1) la prédiction de mouvement à partir d'un résidu différentiel des trames I ou P adjacent dans le temps, et 2) le résidu différentiel de trames P obtenu par la soustraction du résidu de la trame de couches de base P décodées du résidu de la trame de couches de base P d'origine.
