Abstract
(EN)
Disclosed in one provided embodiment is a video decoding method comprising: acquiring, from a bitstream, identification information about a first tile and identification information about a last tile included in a first slice; determining an index difference between the first tile and the last tile on the basis of a result obtained by comparing the identification information about the first tile with the identification information about the last tile; and determining the number of tiles included in the first slice by using the index difference between the first tile and the last tile, thereby decoding, according to an encoding order, a plurality of tiles included in the first slice by using the number of tiles, the identification information about the first tile, and the identification information about the last tile.

Un mode de réalisation de l'invention concerne un procédé de décodage vidéo comprenant les étapes consistant à : acquérir, à partir d'un train de bits, des informations d'identification concernant une première tuile et des informations d'identification concernant une dernière tuile incluses dans une première tranche ; déterminer une différence d'indice entre la première tuile et la dernière tuile sur la base d'un résultat obtenu par comparaison des informations d'identification concernant la première tuile avec les informations d'identification concernant la dernière tuile ; et déterminer le nombre de tuiles incluses dans la première tranche à l'aide de la différence d'indice entre la première tuile et la dernière tuile, ce qui permet de décoder, selon un ordre de codage, une pluralité de tuiles incluses dans la première tranche en utilisant le nombre de tuiles, les informations d'identification concernant la première tuile, et les informations d'identification concernant la dernière tuile.
