Abstract
La présente invention concerne un appareil de décodage vidéo qui améliore les degrés de latitude pour calculer un vecteur de mouvement en sélectionnant un des blocs encloisonnés. Lappareil de décodage vidéo comprend un circuit de traitement configuré pour : acquérir un ou plusieurs blocs disponibles ayant un vecteur de mouvement de blocs décodés adjacents à un bloc à être décodé et un nombre des blocs disponibles; sélectionner un premier bloc à partir des blocs disponibles; sélectionner une pluralité de mots-codes daprès le nombre de blocs disponibles; et décoder les données de sélection spécifiant le premier bloc parmi les blocs disponibles en utilisant un tableau de codes correspondants au premier bloc des blocs disponibles, le tableau de codes comprenant un index et les mots-codes correspondants à lindex, et le bloc à être décodé au moyen dun vecteur de mouvement du premier bloc, dans lequel un nombre de lindex est déterminé en fonction du nombre de blocs disponibles.
