Abstract
In a communication system for carrying out satellite communication through a satellite among users, a satellite communication center is located in a terrestrial network, such as an internet, and has a program table accessible through the terrestrial network and representative of a time schedule of each program to be broadcast through the satellite. The program table can be reserved to broadcast contents by a sender through the internet when an empty time zone is left on the program table. When the reservation is accepted, the contents are sent from the sender through the internet to the satellite communication center and are broadcast at a reserved time through the satellite to other users in accordance with the program table. The contents may be stored in advance in an information storage of the satellite communication center once before they are broadcast or be directly broadcast to the satellite at the reserved time.
