Abstract
(EN)
An example method of decoding video data includes receiving a plurality of pictures, receiving, in a message associated with a first picture of the plurality of pictures, information indicating a picture order count (POC) value of a recovery point picture of a gradual decoder refresh (GDR) set, when a picture that follows the first picture in decoding order has the POC value that is equal to a POC value of the recovery point picture, identifying the picture having the POC value equal to the POC value of the recovery point picture, as a recovery point picture, and when none of the pictures that follow the first picture has the POC value that is equal to the POC value of the recovery point picture, identifying one of the pictures that has a POC value greater than the POC value of the recovery point picture as the recovery point picture.

L'invention concerne un exemple de procédé de décodage de données vidéo comprenant la réception d'une pluralité d'images, la réception dans un message associé avec une première image de la pluralité d'images d'une information indiquant une valeur de comptage de l'ordre des images (POC) d'une image de point de restauration d'un ensemble de rafraîchissement de décodeur graduel (GDR), lorsqu'une image qui suit la première image dans l'ordre du décodage présente la valeur de POC qui est égale à une valeur de POC de l'image du point de restauration, l'identification de l'image qui présente la valeur de POC égale à la valeur de POC de l'image du point de restauration en tant qu'image de point de restauration, et quand aucune des images qui suivent la première image ne présente la valeur de POC qui est égale à la valeur de POC de l'image du point de restauration, l'identification de l'une des images qui présente une valeur de POC supérieure à la valeur de POC de l'image du point de restauration en tant qu'image du point de restauration.
