Abrégé
(EN)
In a multi-medium information sharing system, multi-medium information is shared between a plurality of devices by using a network connected to a server. The server includes: a management table for managing identifiers for identifying a plurality of terminal devices and addresses of the plurality of terminal devices on the network; a server reception section for receiving an identifier from a first terminal device; a processing section for acquiring the address of the first terminal device according to reception of the identifier and acquiring the address of the second terminal device corresponding to the identifier according to the identifier and the management table received; and a server transmission section for notifying the address of the second terminal device to the first terminal device when the first terminal device holds multi-medium information and notifying the address of the first terminal address to the second terminal device when the second terminal device holds the multi-medium information. The first terminal device and the second terminal device transmit/receive the multi-medium information according to the notified address, thereby sharing the information.

L'invention concerne un système de partage d'information multimédia entre plusieurs dispositifs via un réseau relié à un serveur, lequel comprend : table de gestion d'identificateurs de plusieurs dispositifs terminaux et adresses correspondantes sur le réseau, étage de réception d'identificateur depuis un dispositif terminal, étage de traitement pour acquisition d'adresse de premier dispositif terminal selon l'identificateur et de second dispositif terminal selon l'identificateur suivant la réception de l'identificateur et la table de gestion, et étage de transmission pour notification d'adresse de second dispositif terminal au premier dispositif terminal lorsque celui-ci détient une information multimédia et d'adresse du premier au second lorsque celui-ci détient une information multimédia. Les deux dispositifs en question transmettent/reçoivent l'information multimédia selon l'adresse notifiée, aux fins de partage d'information.

 マルチメディア情報共有システムでは、サーバが接続されたネットワークを利用して、複数の装置間でマルチメディア情報が共有される。サーバは、複数の端末装置を特定する識別子および複数の端末装置のネットワーク上のアドレスを管理する管理テーブルと、第1端末装置から識別子を受信するサーバ受信部と、識別子の受信に基づいて第1端末装置のアドレスを取得するとともに、受信した識別子および管理テーブルに基づいて識別子に対応する第2端末装置のアドレスを取得する処理部と、第1端末装置がマルチメディア情報を保持する場合には第2端末装置のアドレスを第1端末装置に通知し、第2端末装置がマルチメディア情報を保持する場合には第1端末装置のアドレスを第2端末装置に通知するサーバ送信部とを備えている。第1端末装置および第2端末装置間は、通知されたアドレスに基づいてマルチメディア情報を送受信して共有する。
