Abstract

On propose un récepteur IPTV et une méthode dacquisition dune ressource pour service sur IP (IPTV). Une interface réseau transmet et reçoit un paquet IP par un réseau. Une pile de réseau IP vérifie la destination du paquet IP reçu et classe le paquet IP selon un protocole. Un décodeur de linformation sur les services (IS) décompose lanalyse dun dossier de service dune télévision sur IP (IPTV) qui contient un localisateur de ressources qui représente lemplacement dune ressource incluse dans le paquet IP et lit un élément enfant contenu dans le localisateur de ressource. Un contrôleur opérationnel de la fonction terminale IPTV (ITF) commande le retrait de la ressource selon les renseignements inclus dans lélément enfant.
