A database communication network system has an entertainment system (12) comprising an entertainment apparatus (102) to which a portable information communication terminal (32) is detachably connected. An individual identification code (individual PDA ID) of the portable information communication terminal (32) and a service request are transmitted from the entertainment system (12) via a bidirectional communication network (16) to a computer system (20) having a server function. The computer system (20) transmits a command representing the individual PDA ID and the service request via a link (22) in the form of a LAN to a computer system (24) having a database. The computer system (24) searches a database to extract information corresponding to a service request, and transmits (broadcasts) the extracted information together with the individual PDA ID via a wireless unidirectional communication network (28) and a link (30) to the portable information communication terminal (32). Only the portable information communication terminal (32) with the individual PDA ID is capable of reproducing the received data.

L'invention concerne un système réseau de communication à base de données équipé d'un système de divertissement (12) comprenant un appareil de divertissement (102) auquel est fixé de manière amovible un terminal de communication d'informations portable (32). Un code d'identification individuel (PDA ID individuel) du terminal de communication d'informations portable (32) et une demande de service sont envoyés via un réseau de communication bidirectionnel (16) du système de divertissement (12) à un système informatique (20) faisant office de serveur. Le système informatique (20) transmet une commande représentant le PDA ID individuel et la demande de service à un système informatique (24) doté d'une base de données via une liaison (22) sous forme de réseau local. Le système informatique (24) recherche une base de données pour extraire les informations correspondant à la demande de service et transmet (diffuse) les informations extraites ainsi que le PDA ID individuel au terminal de communication d'informations portable (32) via un réseau de communication unidirectionnel sans fil (28) et une liaison (30). Seul ce terminal (32) avec le PDA ID individuel est en mesure de lire les données reçues.
