Abstract
(EN)
This disclosure relates to video coding and more particularly to techniques for signaling of tile structures for pictures of coded video. According to an aspect of an invention, a first flag syntax and a second flag syntax are coded in a picture parameter set, wherein the first flag syntax specifies whether tiles within each slice are in raster scan order or the tiles within each slice cover a rectangular region of a picture and the second flag syntax specifies each slice includes only one rectangular region or each slice includes one or more rectangular regions.

La présente invention concerne le codage vidéo et, plus particulièrement, des techniques de signalisation de structures de pavé pour des images de vidéo codée. Selon un aspect de l'invention, une première syntaxe de drapeau et une seconde syntaxe de drapeau sont codées dans un ensemble de paramètres d'image, la première syntaxe de drapeau spécifiant si des pavés à l'intérieur de chaque tranche se situent dans un ordre de balayage de trame ou si les pavés à l'intérieur de chaque tranche couvrent une région rectangulaire d'une image, et la seconde syntaxe de drapeau spécifiant si chaque tranche comprend seulement une région rectangulaire ou si chaque tranche comprend une ou plusieurs régions rectangulaires.
