摘要： 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.

摘要： 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.

摘要： A method of providing video content includes receiving a channel change data packet from a set-top box device at a subscriber premise via a packet-based video distribution network. The channel change data packet includes data indicating a requested channel and a channel change index value. The method also includes reading the channel change data packet to identify the channel change index value. The channel change index value indicates an available bandwidth at the subscriber premise to receive video content of the requested channel via the packet-based video distribution network. The method also includes allocating an overhead bandwidth to the set-top box device based on the channel change index value.

摘要： An SVC is established via an ATM switch port, which includes multiple virtual paths (VPs), by associating multiple virtual user-to-network interfaces (UNIs) to each of the VPs. Each of the VPs includes multiple virtual circuit (VC) ranges, each of which corresponds to a different virtual UNI. Each VC range includes at least one VC for control and at least one VC for data transfer. Associating the virtual UNIs to each of the VPs includes mapping each virtual UNI to a corresponding VC range within a VP based on a virtual path index (VPI)/virtual channel index (VCI) of the virtual UNI initially received by the ATM switch port.

摘要： A circuit for eliminating illegal data sequences from a data stream is disclosed. The circuit examines a portion of an input data stream. The previously received data sequence is then examined. If the previously received data matches an illegal sequence, the stored data is altered. The stored data is then outputted to form an output data sequence.
