Abstract

Un appareil de codage vidéo sert à soumettre une image vidéo à un décodage compensé en mouvement, lappareil comprenant un module dacquisition servant à acquérir le bloc disponible ayant un vecteur de mouvement et un numéro du bloc disponible à partir du bloc décodé adjacent à un bloc à décoder; un module de décodage dinformation servant à décoder linformation de sélection spécifiant le bloc disponible à laide dune table de codes correspondant au numéro du bloc disponible et ne décodant pas linformation de sélection si le numéro du bloc disponible est 1; un module de sélection servant à sélectionner un bloc sélectionné du bloc disponible selon linformation de sélection; et un module de décodage dimage servant à décoder le bloc à décoder à laide dun vecteur de mouvement du bloc sélectionné.
