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.

Claims

1. A receiver in a satellite based IP communication system, said receiver including:

a first processor receiving a signal from a satellite, said signal including IP packets, said first processor extracting at least a portion of said IP packets from said signal; and

a second processor receiving said signal from said satellite, said second processor extracting additional digital data from said signal.

2. The receiver of claim 1 wherein said additional digital data includes IP packets.

3. The receiver of claim 1 wherein said additional digital data includes audio data.

4. The receiver of claim 1 wherein said additional digital data includes video data.

5. The receiver of claim 1 wherein said additional digital data includes at least one of IP packets, audio data, and video data.

6. The receiver of claim 1 wherein said receiver includes a first output port for outputting Ethernet frames.

7. The receiver of claim 6 wherein said receiver includes a second output port for outputting said additional digital data.

8. 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;

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.

9. The method of claim 8 wherein said additional digital data includes IP packets.

10. The method of claim 8 wherein said additional digital data includes audio data.

11. The method of claim 8 wherein said additional digital data includes video data.

12. The method of claim 8 wherein said additional digital data includes at least one of IP packets, audio data, and video data.

13. The method of claim 8 including outputting Ethernet frames through a first output port.

14. The method of claim 13 including outputting said additional digital data through a second output port.

15. A receiver in a satellite based IP communication system, said receiver including:

a first processor receiving a signal from a satellite, said signal including IP packets, said first processor extracting at least a portion of said IP packets from said signal to form a first data stream;

a first output outputting said first data stream from said receiver;

a second processor receiving said signal from said satellite, said second processor extracting additional digital data from said signal to form a second data stream; and

a second output outputting said second data stream from said receiver.

16. The receiver of claim 15 wherein said additional digital data includes IP packets.

17. The receiver of claim 15 wherein said additional digital data includes audio data.

18. The receiver of claim 15 wherein said additional digital data includes video data.
