Title (EN) SYSTEMS AND METHODS FOR TRANSFORM COEFFICIENT CODING
(FR) SYSTÈMES ET PROCÉDÉS DE CODAGE DE COEFFICIENT DE TRANSFORMÉE
Abstract:
(EN) A video coding device may be configured to receive a level value, estimate a characteristic of a reconstructed video block associated with the level value, adjust a quantization scale factor based on the estimated characteristic, and perform a quantization process on the level value based on the adjusted quantization scale factor.
(FR) L'invention concerne un dispositif de codage vidéo qui peut être configuré pour recevoir une valeur de niveau, estimer une caractéristique d'un bloc vidéo reconstruit associé à la valeur de niveau, ajuster un facteur d'échelle de quantification sur la base de la caractéristique estimée, et réaliser un processus de quantification sur la valeur de niveau sur la base du facteur d'échelle de quantification ajusté.
