Abstract

A terminal apparatus accepts information for specifying desired reception time from a user via a key operation section. By using the information specifying the desired reception time and the current time provided by a clock circuit, a control section in the terminal apparatus detects the arrival of the desired reception time. Upon detecting the arrival of the desired reception time, the control section generates a distribution request for demo data and transmits the request to a distribution server apparatus via a communication section. The control section then receives demo data distributed from the distribution server apparatus and stores the demo data in its storage device section, so that the demo data is made available for subsequent use.
