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 by a subscriber terminal in the satellite communications system, the side information being transmitted from a gateway to the subscriber terminal via a first communication path that includes a satellite link, the gateway and the first node being on a first side of the satellite link and the subscriber terminal being on a second side of the satellite link, the gateway and the satellite link being associated with a provider of satellite communication services, and the subscriber terminal being associated with at least one of a plurality of subscribers to the satellite communication services;

    identifying by the subscriber terminal according to the side information that first content is being transmitted from the first node to the second node via the subscriber terminal over the satellite link;

    determining by the subscriber terminal, while the first content is being transmitted from the first node to the second node via the subscriber terminal over the satellite link, that second content is accessible by the second node from a source other than the first node via a second communication path that does not include the satellite link;

    generating, in response to determining the second content is available from a source other than the first node, output content using the second content and the side information so that the output content is substantially the same as the first content; and

    providing the output content to the second node via the second communication path.
