Abstract
A device may include a communication interface configured to receive programming information and index data associated with the programming information from a service provider multicast over a plurality of channels. The device may also include logic configured to request address information from the service provider, receive the address information, wherein the address information includes a first multicast address, and join a first multicast group corresponding to the first multicast address, wherein the first multicast group is associated with the index data. The logic may also be configured to receive, via the communication interface, the index data, identify a second multicast address associated with at least some of the programming information, join a second multicast group corresponding to the second multicast address, and receive, via the communication interface, at least some of the programming information.
