Abstract
A relay server for realizing broadcasting from a network apparatus of one side to a plurality of network apparatus of the other side via the Internet. A first terminal which carries out the communication, makes login to a relay server, and reserves a connection in advance. When carrying out the broadcasting from the first terminal to second and third terminals, the first terminal transmits connection demand information for the second and third terminals to the relay server. When the second and third terminals approve the connection, the relay server associates a first connection with the first terminal and a second connection with the second terminal, and associates a third connection with the first terminal and a fourth connection with the third terminal. Then, the relay server forwards information transmitted from the first terminal to the second and third terminals, and thereby realizes the broadcasting.
