SPACE SHIFTING OVER RETURN SATELLITE COMMUNICATION CHANNELS
First Claim
1. A method for providing content from a first node to a second node using a satellite communications system, the method comprising:
- receiving side information at a gateway in the satellite communications system, the side information being transmitted from a subscriber terminal to the gateway via a first communication path that includes a satellite link;
determining at the gateway that the side information is associated with first content available at the first node;
determining at the gateway that second content is available from a source other than the first node;
generating output content using the second content and the side information, the output content being substantially the same as the first content; and
providing the output content to the second node via a second communication path that does not include the satellite link.

Abstract
A method for providing content from a first node to a second node using a satellite communications system includes receiving side information at a gateway in the satellite communications system. The side information may be transmitted from a subscriber terminal to the gateway via a first communication path that includes a satellite link. The method also includes determining at the gateway that the side information is associated with first content available at the first node, and determining at the gateway that second content is available from a source other than the first node. The method also includes generating output content using the second content and the side information. The output content may be substantially the same as the first content. The method also includes providing the output content to the second node via a second communication path that does not include the satellite link.

12. A gateway for providing content from a first node to a second node using a satellite communications system, comprising:
-
a receiving module configured to receive side information transmitted from a subscriber terminal via a first communication path that includes a satellite link; a first determining module configured to determine that the side information is associated with first content available at the first node; a second determining module configured to determine that second content is available from a source other than the first node; a generating module configured to generate output content using the second content and the side information, where the output content is substantially the same as the first content; and a providing module configured to provide the output content to the second node via a second communication path that does not include the satellite link. - View Dependent Claims (13, 14, 15, 16)

17. A satellite communications system for transmitting content from a first node to a second node, comprising:
-
a source encoder configured to receive first content from the first node and generate side information associated with the first content; a subscriber terminal configured to transmit the side information via a satellite link; and a gateway configured to receive the side information via the satellite link and configured to; determine that the side information is associated with the first content; determine that second content is available from a source other than the first node; generate output content using the second content and the side information, where the output content is substantially the same as the first content; and provide the output content to the second node via a communication path that does not include the satellite link. - View Dependent Claims (18, 19, 20)
