Abrégé
(EN)
A decentralized approach to delivering a media file to a requesting subscriber in a network of subscribers (22) comprises the steps of segmenting the media file into a plurality of segments and distributing the segments of the media file among the network of subscribers, and responding to a request from the requesting subscriber by directing to that requesting subscriber all of the plurality of segments of the media file (28). All of segments are assembled into the media file and displayed (30) or stored (46) by the requesting subscriber.

Cette invention concerne une technique décentralisée de diffusion d'un fichier multimédia à un abonné requérant dans un réseau d'abonnés. Cette technique consiste à partager le fichier multimédia en une pluralité de segments et à répartir les segments du fichier multimédia dans le réseau d'abonnés, puis à répondre à une demande provenant de l'abonné requérant en adressant audit abonné requérant l'ensemble des segments du fichier multimédia. L'ensemble des segments est assemblé dans le fichier multimédia et affiché ou stocké par l'abonné requérant.
