要約
(EN) In order to protect a content holder, a server device (20) holds distribution control information defining a content of the number of terminals to which the same part of the content can be simultaneously distributed. When a reproduction request of the content is received from a plurality of terminals, content distribution to the respective terminals is controlled without exceeding the number of terminals defined in the distribution control information.
(FR) Afin de protéger un détenteur de contenus, un dispositif serveur (20) conserve l'information de commande de distribution définissant un contenu du nombre de terminaux auxquels la même partie du contenu peut être simultanément distribuée. Quand une requête de reproduction de contenus est reçue de la part de plusieurs terminaux, la distribution de contenus aux terminaux respectifs est commandée sans excéder le nombre de terminaux définis dans l'information de commande de distribution.
(JA)  コンテンツホルダの保護を図るために、本発明のサーバ装置20は、コンテンツと、当該コンテンツの同一部分を同時に配信することが可能な端末装置の台数を規定した配信制御情報とを保持しており、複数の端末装置から前記コンテンツの再生要求を受け付けた場合には、前記配信制御情報に規定された台数を超えることなく、各端末装置へのコンテンツ配信を制御する。
