Abstract
A client terminal CT transmits an acquisition request for musical composition information. An associated information provision server KS continuously receives the acquisition request at a given time interval. The associated information provision server KS transmits timing specification information along with the musical composition information corresponding to the acquisition request to the client terminal CT. The timing specification information specifies timing for the client terminal CT to transmit the acquisition request next. The associated information provision server KS controls a polling interval for acquisition requests. In this manner, acquisition requests can be distributed to those transmitted at a given time interval and those received in accordance with the timing specification information. A simple method can be used to prevent acquisition requests from being concentrated on the associated information provision server KS.
