ITU-T H.222.0 v8 (2021) Amd. 1 (12/2022)

Acheminement du codage LCEVC et autres améliorations

La Recommandation UIT-T H.222.0 | ISO/CEI 13818-1 a été élaborée en 1994, principalement pour assurer la combinaison et la synchronisation des méthodes de codage vidéo et audio définies dans la Partie 2 (UIT-T H.262) et la Partie 3 de l'ISO/CEI 13818. Depuis lors, cette norme a été enrichie afin de prendre en charge d'autres spécifications de codage vidéo et audio ainsi que de multiples types de mégadonnées.
L'Amendement 1 à la Recommandation UIT-T H.222.0 (2021) | ISO/CEI 13818-1:2022, enrichit la spécification en définissant comment le codage LCEVC (ISO/CEI 23094-2) est acheminé dans des systèmes MPEG-2. Il définit en outre un descripteur additionnel qui signale le type de service média et son utilisation. Par ailleurs, il contient des précisions sur la spécification de l'acheminement des données JPEG XS.
Toutes ces opérations sont faites d'une manière qui est compatible avec la prise en charge existante des autres codecs.
