Abstract
Est divulgué un dispositif de décodage de signal vidéo. Le dispositif de décodage comprend un processeur. Le processeur divise un bloc courant en de multiples zones selon une ligne de référence, et effectue une prédiction pour chaque zone divisée. Au moins l'une des multiples zones est prédite par l'intermédiaire d'une prédiction intra.
