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 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.
摘要翻译：通过将多个虚拟用户到网络接口（UNI）与每个VP相关联，通过ATM交换机端口建立SVC，其包括多个虚拟路径（VP）。每个VP包括多个虚拟电路（VC）范围，每个虚拟电路范围对应于不同的虚拟UNI。每个VC范围包括用于控制的至少一个VC和用于数据传输的至少一个VC。将虚拟UNI与每个VP相关联包括基于最初由ATM交换机端口接收的虚拟UNI的虚拟路径索引（VPI）/虚拟信道索引（VCI）将每个虚拟UNI映射到VP内的相应VC范围。
