Abstract

Un décodeur à base de blocs, permettant de décoder une image à partir d'un flux de données en unités de codage, est configuré pour diviser un bloc d'image de l'image en blocs de codage par un bi-partitionnement récursif. La commande du bi-partitionnement récursif en fonction d'informations de partition dans le flux de données définit une première direction de ligne de division d'une première ligne de division le long de laquelle un sous-bloc prédéfini d'un niveau de division prédéfini de l'image est divisé par le bi-partitionnement récursif en ladite paire de sous-blocs enfants d'un niveau de division suivant dépendant d'une seconde direction de ligne de division d'une seconde ligne de division le long de laquelle un sous-bloc grand-père d'un niveau de division précédent du bloc d'image est divisé en ledit sous-bloc prédéfini et en un autre sous-bloc.
