ITU-T H.721 (03/2009)

Dispositifs terminaux de TVIP: Modèle de base

La Recommandation UIT-T H.721 décrit et spécifie les fonctionnalités des dispositifs terminaux de TVIP pour les services de base de TVIP définis dans la Recommandation UIT-T H.720. Cette Recommandation s'applique aux dispositifs terminaux de TVIP capables de recevoir des services de télévision linéaire ou de vidéo à la demande, ainsi qu'un contenu de données supplémentaire (par exemple du texte) au moyen d'un réseau géré de fourniture de contenu. Dans la définition des services, il est tenu compte de conditions relatives à la fourniture de contenu telles que la qualité de service. Les types attendus de dispositifs terminaux de TVIP sont les boîtiers-décodeurs et les téléviseurs numériques avec capacités intégrées de TVIP.
