Title (EN) DATA DISTRIBUTION SYSTEM
(FR) SYSTEME DE DISTRIBUTION DE DONNEES
Abstract: front page image
(EN)Through the internet (40), download servers (31. 1 to 30. n) transmit content data encrypted by LCM encoders (31.1 to 31.n) according to encryption methods corresponding to the download servers (30.1 to 30.n). In response to a content distribution request of a mobile telephone (100), a distribution server (30) receives the data through the Internet (40), decodes the received data by LCM decoders (11.1 to 11.n), encrypts the content data requested by the mobile telephone (100) by a predetermined encryption method, and distributes it by radio.
(FR)L'invention concerne un procédé dans lequel des serveurs de téléchargement (31.1 à 30.n) transmettent, par le biais de l'Internet (40), des données de contenu, codées par des codeurs LCM (31.1 à 31.n) selon des procédés de codage correspondant aux serveurs de téléchargement (30.1 à 30.n). En réponse à une demande de distribution de contenu émanant d'un téléphone mobile (100), un serveur de distribution (30) reçoit les données par le biais de l'Internet (40), décode les données reçues au moyen de décodeurs LCM (11.1 à 11.n), code les données de contenu demandées par le téléphone mobile (100) selon un processus de codage déterminé, et distribue ces données par radio.
