Abstract

L'invention concerne un dispositif partagé, un programme de commande de fonctionnement et un procédé de commande de fonctionnement qui sont prévus de telle sorte que le partage d'informations entre des dispositifs dans un système de partage d'informations peut être obtenu par une opération de connexion simple. Dans le système de partage d'informations comprenant des terminaux clients, un dispositif partagé et un serveur de signalisation, le dispositif partagé acquiert des informations d'identification pour lui-même en se connectant au serveur de signalisation et transmet des informations de connexion aux terminaux clients lorsqu'il est accédé par les terminaux clients, lesdites informations de connexion comprenant des informations d'adresse pour le serveur de signalisation sur le réseau de communication et les informations d'identification du dispositif partagé. Lors de la réception des informations de connexion, les terminaux clients se connectent au serveur de signalisation en utilisant les informations d'adresse du serveur de signalisation, avertissant le serveur de signalisation des informations d'identification du dispositif partagé, effectuer une interrogation concernant une condition de connexion au dispositif partagé, et partager des informations avec le dispositif partagé conformément à la condition de connexion obtenue.
