Abstract
L'invention concerne un procédé et un dispositif de transmission, en continu, d'un contenu en direction d'un réseau d'accès, dans un système interactif de distribution d'informations (100), ce procédé consistant d'abord à encapsuler le contenu selon un protocole Internet (IP). Dans un mode de réalisation, le contenu est configuré sous forme de plusieurs paquets MPEG-2 contenus dans une charge utile d'un paquet de protocole de transport en temps réel (352-356), inclus dans un paquet IP (300). Le contenu est alors transcodé en un format supporté par le réseau d'accès et transmis en continu sur un réseau de distribution, à destination d'un serveur à distance (201), ou à un terminal d'abonné couplé au réseau d'accès (104). Le dispositif de l'invention est constitué comme au moins un serveur de mise en antémémoire de flux (102), aux fins de transmission de ce flux, en continu, à au moins un réseau d'accès, en tant que paquet de Protocole Internet (IP), par l'intermédiaire d'un réseau de distribution de flux, en réponse à une demande de contenu, ce contenu étant encapsulé dans le paquet IP. Un processeur de paquets (144) est couplé au moins au serveur de flux, aux fins de traitement du contenu encapsulé dans les paquets IP et de mise sous forme d'un paquet dont le format est spécifique d'au moins le réseau d'accès.
