PURPOSE: To improve user's convenience and to eliminate the necessity of stock management by allowing a host station to transmit stored game data by satellite communication and allowing each terminal equipment to select the stored gate data and write the selected data in an optical disk.

CONSTITUTION: The host station stores much gate data and cyclically transmits these stored data to all terminal equipments by satellite communication. On the other hand, each terminal equipment receives these game data through an antenna 2 and a tuner 3 and manages/stores the received data in a large scale storage device 4 in each file. When a user selects required game data out of data stored in the device 4 at the time of writing the game data in an optical disk 8, a controlling CPU 1 reads out a necessary file from the device 4 by using a RAM 6 as a working area and writes the read file in the disk 8 in accordance with a prescribed format. Consequently the user can quickly obtain the required game and the stock management in each game is made unnecessary.
