Abstract

L'invention concerne un système de distribution sécurisée et non sécurisée de contenu numérique, tel que des données audio ou vidéo numériques, sur Internet ou d'autres réseaux informatiques, partant d'un serveur vers un ordinateur personnel ou toute autre plate-forme informatique, en passant par la conversion de données audio et vidéo analogiques, pour arriver à l'écoute ou au visionnement du contenu sur un lecteur audio ou vidéo. Un aspect important de l'invention concerne la transmission sans fil de données audio ou vidéo numériques ou de données audio ou vidéo analogiques depuis une plate-forme informatique, par un périphérique de transmission audio ou vidéo, vers un dispositif de réception audio ou vidéo et finalement vers un lecteur audio ou vidéo.
