SPACE SHIFTING OVER FORWARD SATELLITE COMMUNICATION CHANNELS

摘要

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.
