ABSTRACT:
The present invention provides an information processing system enabled to transmit and receive video mails at a higher transfer rate and at reduced cost. In this system, a file server sends a low capacity notification mail, which notifies the presence of a video mail sent from a portable terminal, to another portable terminal. This portable terminal accesses the file server in response to the notification mail, and downloads the video mail therefrom via a WLAN network that is a broadband communication line.
