Abstract

La présente invention concerne un encodeur vidéo, un décodeur vidéo et un procédé correspondant pour coder et décoder des données de signal vidéo utilisant un schéma de codage vidéo à passage multiple. L'encodeur vidéo inclut un estimateur de mouvement (116) et un module de décomposition (174). L'estimateur de mouvement effectue une estimation de mouvement sur les données de signal vidéo afin d'obtenir un résidu de mouvement correspondant aux données de signal vidéo dans un premier passage de codage. Le module de décomposition, en communication par signal avec l'estimateur de mouvement, décompose le résidu de mouvement dans un passage de codage successif.
