<p>An information processing terminal which is connected through a network and can easily effect a version-up of its software. When the version-up of a control program stored in a display device (5B) is effected by a control program stored in a memory card (10), the version-up program of a base station (1) read out of the display device (5B) and the control programs of the display devices (5A and 5B) are transmitted to the base station (1). With the version-up program received, the base station (1) executes the version-up of the control program stored, and transmits the control programs of the display devices (5A and 5C) to the display devices (5A and 5C). The display devices (5A and 5C) execute the version-ups of the control programs stored, with the received version-up programs.</p> |
