Abstract: A method includes receiving data from a set-top box device at an access system via an access network, the data indicating a selection of a channel at the set-top box device, the data including a multicast group address. The method also includes sending copies of video data packets of the channel from the access system for storage in a first-in first-out cache associated with the channel. The method further includes automatically connecting the set-top box device to a multicast stream of the selected channel after a particular number of video data packets are sent to the set-top box device from the cache. The particular number of video data packets corresponds to a time period between communicating successive random access point packets of the channel and is less than a capacity of the cache.

Abstract: A method is disclosed that includes receiving a data packet at a first video distribution hub via a first link. The method also includes determining whether a second link has failed, wherein the first video distribution hub communicates with a second video distribution hub via a primary network path that includes the second link. When the second link has failed, a backup network path to send the data packet, or a copy thereof, to the second video distribution hub, is determined based on data stored at the first video distribution hub. The method also includes sending the data packet, or the copy thereof, to the second video distribution hub via the backup network path, wherein the backup network path does not include the second link.
