Abstract

L'invention porte sur une méthode de traitement d'informations sur des canaux, et sur un récepteur. Le récepteur comporte un premier gestionnaire, un gestionnaire de canaux et un deuxième gestionnaire. Le premier gestionnaire peut recevoir: un paquet incluant des informations sur la découverte d'un prestataire de services y compris des informations sur son identification, et un paquet incluant des informations sur la découverte d'un service y compris des informations sur l'identification du fournisseur de contenu et sur l'identification du service de contenus, et extrait les informations contenues dans les paquets. Le deuxième gestionnaire peut effectuer une opération de contrôle pour former des informations de sources multiples sur les canaux en utilisant les informations d'identification, et recevoir un service de contenu d'un canal correspondant aux informations de sources multiples sur les canaux.
