| Systèmes et équipements terminaux visiophoniques à bande étroite |
 |
La présente Recommandation spécifie les caractéristiques techniques des systèmes et équipements terminaux visiophoniques à bande étroite. Elle décrit une configuration de système générique composé d'un certain nombre d'éléments définis dans d'autres Recommandations de l'UIT-T et traite des modes de communication et des types de terminaux, des procédures d'appel, des aspects relatifs aux terminaux et des spécifications d'interfonctionnement. Dans cette version révisée de la Rec. UIT-T H.320, un certain nombre d'améliorations et de précisions ont été apportées essentiellement à la description de l'application des Recommandations UIT-T G.722.1, H.239, H.241 et H.264 et de l'ISO/CEI 14496-3 aux systèmes H.320. |
