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 apparatus (5B) is upgraded by a control program stored on a memory card (10), an upgrade program for a base station (1) and the control program for display apparatus (5A) and (5C) read by the display apparatus (5B) are transmitted to the base station (1). The base station (1) upgrades a control program stored therein by the upgrade program received by the base station (1), and also transmits the control program for the display apparatus (5A) and (5C) to the display apparatus (5A) and (5C). The display apparatus (5A) and (5C) each upgrade a control program stored therein by the upgrade program received by the display apparatus (5A) and (5C), respectively.

L'invention concerne un terminal de traitement de l'information connecté par un réseau et pouvant mettre facilement à niveau son logiciel. Lorsque la mise à niveau d'un programme de commande mémorisé dans un dispositif d'affichage (5B) est effectuée par un programme de commande mémorisé dans une carte mémoire (10), le programme de mise à niveau explore le dispositif d'affichage (5B) d'une station de base (1) et les programmes de commande des dispositifs d'affichage (5A et 5B) sont transmis à la station de base (1). Lorsque le programme de mise à niveau est reçu, la station de base exécute la mise à niveau du programme mémorisé et transmet les programmes de commande des dispositifs d'affichage (5A et 5C) aux dispositifs d'affichage (5A et 5C). Les dispositifs d'affichage (5A et 5C) exécutent les mises à niveau des programmes de commande mémorisés, à l'aide des programmes de mise à niveau reçus.
