CA 2592515

A deblocking filter used in a video encoder/decoder based on a multilayer is disclosed. The deblocking filtering method includes choosing a present block and its neighboring block on which a deblocking filtering will be performed, judging whether the present block and the neighboring block have been coded by the intra BL mode, choosing a deblocking filter strength according to the result of the judgment, and performing the deblocking filtering with respect to a boundary between the present block and the neighboring block and according to the deblocking filter strength.

La présente invention a trait à un filtre de déblocage utilisé dans un codeur/décodeur vidéo basé sur une multicouche. Le procédé de filtrage de déblocage comprend la sélection d'un bloc actuel et de son bloc voisin sur lesquels va être réalisé un filtrage de déblocage, la détermination de codage en mode intra-bloc de base ou non sur le bloc actuel et le bloc voisin, la sélection d'une puissance de filtre de déblocage selon le résultat de la détermination, et la réalisation du filtrage de déblocage par rapport à une limite entre le bloc actuel et le bloc voisin et selon la puissance du filtre de déblocage.
