ABSTRACT:
The present invention relates to an information processing terminal that makes it possible to readily upgrade software of information processing terminals connected by a network. When a control program stored in a display apparatus5B is upgraded by a control program stored on a memory card10, an upgrade program for a base station1and the control program for display apparatus5A and5C read by the display apparatus5B are transmitted to the base station1. The base station1upgrades a control program stored therein by the upgrade program received by the base station1, and also transmits the control program for the display apparatus5A and5C to the display apparatus5A and5C. The display apparatus5A and5C each upgrade a control program stored therein by the upgrade program received by the display apparatus5A and5C, respectively.
