Abstract

Sont divulgués, un procédé et un système de fourniture et de lecture de contenu à partir d'un fournisseur de services. Le procédé consiste à recevoir, sur un dispositif frontal, qui peut être configuré ou sélectionné sur la base de différents procédés de distribution de contenu, un contenu original en provenance du fournisseur de services; à démultiplexer, sur le dispositif frontal, le contenu original provenant du fournisseur de services; à ajouter, par le dispositif frontal, un horodatage au contenu d'origine pour convertir le contenu d'origine en paquets de flux de transport MPEG horodatés (MPEG-TTS); à convertir, par le dispositif frontal, les paquets de flux de transport MPEG horodatés (MPEG-TTS) en paquets de protocole Internet (IP); et à transférer, par le dispositif frontal, les paquets IP avec les paquets de flux de transport MPEG horodatés (MPEG-TTS) vers une passerelle pour une transmission à un décodeur. Le décodeur est configuré pour déchiffrer et décoder un contenu reçu en provenance de la passerelle sur le réseau sans fil et transfert le contenu décodé à un dispositif d'affichage.
