Satellite IP multicasting system and method

The present invention relates to a satellite IP multicast system and method for constructing IP multicast network nodes via the Internet with a router or switch unit for connecting the user and for transmitting via a satellite transmission from a content provider of the multicast packet IP multicast to the local network. IP Multicast system includes satellite backbone, content providers, satellite networks and local networks. Local network backbone associated acting on the protocol being configured to multicast router or switch, and by the static multicast router routing on a user's setting, and by specifying a group connected to the satellite network via a router or Ethernet switch IP subnet specified port of the same multicast packet source address of the IP header of the IP packet to the satellite data receiver is connected to the output port and the receiver of the satellite data router performs reverse path forwarding, multicast packets and sent to the terminal Client computer.
