Patent

CA 2390435

A duplication/delivery center DDS records contents C11 and C12 on a recording medium M in accordance with requests from content providing apparatuses CP11 and CP12, duplicates the recording medium M, and delivers the recording medium M to users. When doing so, parts of the contents are encrypted. The content providing apparatuses CP11 and CP12 request a content control apparatus CC1 to control the contents on the recording media M. At the side of contents users, when a user sets a recording medium M in a video game console GM and tries to use a content that has been encrypted, the video game console GM requests, via a mobile packet communication network MPN, the content control apparatus CC1 to transmit a decryption key. The content control apparatus CC1 decides whether or not to transmit the decryption key based on the content of the request received from the content providing apparatus.

Dans un centre de duplication/distribution (DDS), en réponse à des demandes de dispositifs de fourniture de contenus (CP11 et CP12), des contenus (C11 et C12) sont enregistrés et dupliqués sur un support d'enregistrement (M) et sont distribués à un utilisateur. Les contenus sont cryptés partiellement. Les dispositifs fournisseurs de contenus (CP11 et CP12) demandent à un dispositif (CC1) de gestion de contenu de gérer les contenus sur le support d'enregistrement (M). Lorsque l'utilisateur des contenus utilise les contenus lesquels sont chiffrés par chargement du support d'enregistrement (M) dans une machine de jeu (GM) de TV, la machine de jeu (GM) de TV demande au dispositif (CC1) de gestion de contenu de transmettre une clé de décodage par un réseau de communication (MPN) de paquets mobile. Le dispositif (CC1) de gestion de contenu détermine si oui ou non la clé de décodage est à transmettre, sur la base du contenu de la demande provenant du dispositif fournisseur de contenu.
