Abstract

L'invention concerne un procédé de codage et décodage vidéo extensible et à granularité fine et un appareil pouvant commander le déblocage. Dans le procédé de décodage vidéo de l'invention, les données vidéo originales sont reçues et une couche de base est générée selon les données originales. La différence entre les données originales et les données obtenues par reconstruction de la couche de base et déblocage de la couche de base sont obtenues, ce qui génère une couche d'extension. Une trame reconstruite est ensuite générée en fonction des données qui sont obtenues par la reconstruction de la couche d'extension, et des données qui sont obtenues par reconstruction et déblocage de la couche de base reconstruite. Finalement, la trame reconstruite est débloquée à une intensité inférieure à celle du déblocage assuré dans les deux première étapes.
