Satellite receiver/router, system, and method of use
First Claim
1. A method for processing a signal in a satellite based IP communication system, said method including:
- receiving a signal from a satellite at a receiver, said signal including IP packets and said receiver including an Ethernet/router card;
routing a first portion of said signal to a first processor;
extracting at least a portion of said IP packets from said first portion of said signal using said first processor;
routing a second portion of said signal to a second processor; and
extracting additional digital data from said second portion of said signal using said second processor;
wherein said Ethernet/router card is removably inserted into a slot of the receiver and comprises a receiver backplane interface that provides the card with a clock and a packetized TCP/IP data stream, and a depacketizer that receives as input the packetized TCP/IP data stream and outputs TCP/IP packets and data.

Abstract
This specification discloses a satellite transmission system for transmission of TCP/IP compatible packets from a head end computer through a satellite uplink, an extraterrestrial satellite, a satellite downlink, and an integrated satellite receiver/router for outputting of the TCP/IP compatible packets through a port on the receiver/router onto a computer LAN or WAN. The system may include an Internet or telecommunications backchannel. The receiver becomes router enabled by means of a removable insertion Ethernet/Router insertion card inserted into a slot in the receiver, although the transmission system may be used to simultaneously transmit a variety of other services through the receiver by use of other service slots in the receiver. The Ethernet/Receiver supports the IGMPv2 Multicasting (querier and non querier modes), standard TCP/IP (including UDP and Telnet), and SNMP protocols.
