Abstract

Cette invention concerne un procédé de définition d'une profondeur d'arbre quaternaire résiduel (RQT) maximale en codage vidéo. Spécifiquement, une profondeur de RQT maximale pour des composantes de chrominance (chroma) est autorisée à être différente de celles pour des composantes de luminance (luma). Dans ce but, de nouveaux éléments de syntaxe pour la profondeur de RQT maximale pour des composantes de chrominance sont proposés pour être ajoutés dans SPS, PPS, APS, un en-tête de tranche ou n'importe quel autre ensemble de paramètres.
