Abstract
A satellite value added communication system includes an information distribution center which connects to a satellite ground station and controls transmission/receiving of information to/from a satellite communication terminal. The information distribution center connects to the Internet based on a request from the terminal, and distributes predetermined contents to the terminal. The information distribution center connects to a variety of networks, and based on requests of users through the networks, distributes a large amount of information (contents) directly to user's terminals through a communication satellite. In this system, the information distribution center can control a conference or a seminar among the terminals.
Claims24
