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.

21. A method for providing content to a first node in a satellite communications system, the method comprising:
-
receiving side information at a first terminal over a satellite link from a second terminal; determining, by the first terminal, from the side information that transmission of first content from a second node over the satellite link to a first node is pending, wherein the first node is on a same side of the satellite link as the first terminal and the second node is on a same side of the satellite link as the second terminal; determining, by the first terminal, that alternative content that is substantially the same as the first content is accessible to the first node via a communications path that does not include the satellite link; obtaining the alternative content; and providing the alternative content to the first node. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A terminal in a satellite communications system, the first terminal comprising:
-
a receiving module configured to receive side information over a satellite link from a second terminal; an identification module configured to determine from the side information that transmission of first content from a second node over the satellite link to a first node is pending, wherein the first node is on a same side of the satellite link as the first terminal and the second node is on a same side of the satellite link as the second terminal; an identification module configured to determine that alternative content that is substantially the same as the first content is accessible to the first node via a communications path that does not include the satellite link; and a providing module configured to obtain the alternative content and provide the alternative content to the first node. - View Dependent Claims (35)

36. A satellite communications system comprising:
-
a first terminal; a second terminal; and a satellite link connecting the first terminal to the second terminal, wherein the first terminal comprises; a receiving module configured to receive side information over the satellite link from the second terminal, an identification module configured to determine from the side information that transmission of first content from a second node over the satellite link to a first node is pending, wherein the first node is on a same side of the satellite link as the first terminal and the second node is on a same side of the satellite link as the second terminal, a determining module configured to determine that alternative content that is substantially the same as the first content is accessible to the first node via a communications path that does not include the satellite link, and a providing module configured to obtain the alternative content and provide the alternative content to the first node; and wherein the second terminal comprises a transmitting module configured to transmit the side information over the satellite link to the first terminal. - View Dependent Claims (37, 38, 39, 40)
