摘要

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.
