| Gestion des rôles et canaux de média additionnels pour les terminaux de la série H.300 |
 |
La présente Recommandation définit les procédures permettant l'utilisation de plusieurs canaux vidéos dans des systèmes de type H.320 et l'étiquetage des canaux par des "rôles", indiquant les besoins du canal en matière de traitement et le rôle du contenu du canal dans la communication. Ces étiquettes de rôle sont applicables aux systèmes de signalisation H.320 et H.245. Ces procédures incluent des mécanismes de commande, d'indication et d'échange de capacités.La présente version révisée 2005 intègre les corrections apportées dans le Guide d'implémentation H.239 (2003). |
