The system includes an image display device 1 and a management server 5 that can communicate with each other. In the management server 5, it is determined whether the installation of the data into the image display device 1 is permitted. When permission is granted, the installation permission data is transmitted from the management server 5 to the image display device 1. If not permitted, the management server 5 transmits the installation disapproval data to the image display device 1. The image display device 1 stores identification data “DI-ID1” unique to the image display device 1.

In this embodiment, a user purchases a CD (compact disk) 3 and an FD (floppy disk) 4 corresponding to the CD 3 from a store in exchange for the price.

The CD 3 includes image data to be installed in the image display device 1 and CD-specific identification data “CD
−ID1 ”is stored. Also, FD4 has FD
The unique identification data “FD-ID1” is stored.
Further, the FD 4 stores identification data unique to the image display device and a CD in a database of the management server 5 as described later.
When the identification data of No. 3 and the identification data of FD 4 are stored, a registration flag of “registered” is set.
When the FD 4 is purchased, it is needless to say that “unregistered” is set.

The purchased FD 4 is loaded in the image display device 1. The flag stored in FD4 is confirmed. Further, “FD-ID1” stored in FD4 is read. Further, the identification data “DI-ID1” stored in the image display device 1 is read. The purchased CD3 is also loaded into the image display device 1, and the identification data “CD-ID1” stored in the CD3 is read.

The identification data “DI-ID1” of the image display device 1 read from the image display device 1, the identification data “FD-ID1” of the FD read from the FD4, and the CD
CD identification data "CD-ID1" read out from CD3
Is transmitted from the image display device 1 to the management server 5.
