| Codes indépendants du codage pour l'identification du type de signal vidéo |
La Recommandation UIT-T H.273 définit différents points de code et champs qui établissent les propriétés d'une représentation vidéo (ou d'une image fixe) et sont indépendants du codage avec compression et du débit. Ces propriétés peuvent décrire l'interprétation appropriée des données décodées ou, de la même manière, décrire les caractéristiques de ce signal avant que ces signaux soient compressés par un codeur adapté pour la compression de ces signaux d'entrée. Cette Recommandation est un texte jumelé correspondant aux points de code vidéo définis dans la norme ISO/CEI 23 001-8:2016 et son Amendement 1, élaboré en collaboration avec l'ISO/CEI JTC 1 SC 29/WG 11 (MPEG). Elle sera publiée sous la forme de textes jumeaux alignés sur le plan technique par les deux organisations (UIT-T et ISO/CEI). |

| Observation: | ITU-T H.273 (2016) was published as a twin text technically aligned with ISO/IEC 23001-8:2016 and its Amendment 1. After ISO/IEC 23001-8:2016 was split into three parts in 2019 and renumbered as ISO/IEC 23091 parts 1, 2 and 3, ITU-T H.273 remained technically aligned to ISO/IEC 23091-2:2019. |
