Abstract
(EN)
An image decoding method according to the present invention may include: a step for dividing a picture into a plurality of tiles; and a step for determining at least one slice on the basis of the plurality of tiles. Here, the step for dividing a picture into a plurality of tiles may include: a step for determining the width of a first tile column in the picture; and a step for determining the width of a second tile column neighboring the first tile column.

La présente invention concerne un procédé de décodage d'image pouvant comprendre : une étape consistant à diviser une image en une pluralité de pavés ; et une étape consistant à déterminer au moins une tranche sur la base de la pluralité de pavés. Selon l'invention, l'étape de division d'une image en une pluralité de pavés peut comprendre : une étape consistant à déterminer la largeur d'une première colonne de pavés dans l'image ; et une étape consistant à déterminer la largeur d'une seconde colonne de pavés voisine de la première colonne de pavés.
