Title
(EN) METHOD AND APPARATUS FOR CABAC CODING
(FR) PROCÉDÉ ET APPAREIL DE CODAGE CABAC
Abstract
(EN)
An apparatus and method for CABAC decoding are provided. The method includes receiving a bitstream from an encoder, wherein the bitstream includes at least one coding block; and decoding a current coding block by using Context-Adaptive Binary Arithmetic Coding (CABAC) independent from an intra mode of the coding block. The method decouples CABAC parsing and intra mode derivation, and thus a higher throughput of decoding can be achieved.
(FR)
L'invention concerne un appareil et un procédé de décodage CABAC. Le procédé consiste : à recevoir d'un codeur un train de bits comprenant au moins un bloc de codage; et à décoder un bloc de codage courant au moyen d'un codage arithmétique binaire adapté au contexte (CABAC) indépendant d'un mode intra du bloc de codage. Le procédé dissocie l'analyse CABAC et la dérivation en mode intra, ce qui permet d'obtenir un débit de décodage supérieur.
