Abstract
(EN)
A gateway device implemented as a foreign gateway (305) acquires an address (external gateway specification information) of a home gateway (304) via mobile terminal (307). According to the acquired address, a communication channel with the home gateway (304) is established. Via the communication channel, it is possible to reproduce a content under control of the home gateway (304) in a renderer (306) under control of the local device. Thus, it is possible to realize a gateway device enabling a user to view a content accumulated in a server at home by a reproduction terminal in another home.

La présente invention concerne un dispositif de passerelle mis en œuvre comme une passerelle étrangère (305) qui acquiert une adresse (information de spécification de passerelle externe) d'une passerelle domestique (304) via un terminal mobile (307). Selon l'adresse acquise, un canal de communication est établi avec la passerelle domestique (304). Par l'entremise du canal de communication, il est possible de reproduire un contenu sous contrôle de la passerelle domestique (304) dans un moteur de rendu (306) sous le contrôle du dispositif local. Il devient alors possible de réaliser un dispositif de passerelle permettant à un utilisateur de visionner un contenu accumulé dans un serveur à la maison par un terminal de reproduction dans une autre maison.

 フォーリンゲートウェイ(305)として実現された本発明のゲートウェイ装置は、携帯端末(307)を介してホームゲートウェイ(304)のアドレス(外部ゲートウェイ指定情報)を取得するので、取得したアドレスに基づいてホームゲートウェイ(304)との間に通信経路を確立し、この通信経路を介してホームゲートウェイ(304)の管理下にあるコンテンツを、自機の管理下にあるレンダラ(306)にて再生させることができる。これにより、自宅内のサーバに蓄積されたコンテンツを、別宅内の再生端末で視聴することを可能にするゲートウェイ装置を実現する。
