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： A method and apparatus for automatic synchronization of monitoring points for a network management system (“NMS”) along a permanent virtual circuit (“PVC”) is disclosed. A NMS in an synchronous transfer mode (“ATM”) network coupled to a plurality of ATM switches is operative to monitor each of the plurality of ATM switches storied in a monitoring service object corresponding to a PVC. The NMS receives at least one notification from at least one ATM switch of the plurality of ATM switches indicating an ATM switch has been added or removed from the PVC. In response to the at least notification, the NMS adds at least one ATM switch to the monitoring service object or removes at least one ATM switch from the monitoring service object.

摘要： A system is disclosed for detecting paketization delay of packets in a network. The system includes a router to receive at least one packet containing data. A detection system, which is in communication with the router, extracts a codec information and a packet length information from the packet. A management system, which is in communication with the router, receives the codec information and the packet length information and determines packetization delay based on the codec information and the packet length information.

摘要： An adjustable bit rate (ABR) feedback control scheme is provided where the effects of multiloop delays and high priority traffic transmission are built into the control model. The data traffic is filtered by a low pass filter. Then, the low frequency bandwidth of the filtered traffic is measured and compared to a predetermined threshold. If the measured value exceeds the threshold, the ABR traffic flow is reduced. If the measured value is less than the threshold, the ABR traffic flow is increased. In addition, a General Prediction Control (GPC) method may be applied to the control model for optimal performance. An object of the invention is to minimize the unused link capacity subject to no congestion, where the ABR traffic is adapted to the low frequency variation of high priority traffic flow for high efficiency.

摘要： A system and method of delivering video content is disclosed. In a particular embodiment, the method includes receiving channel selection data from a set-top box device via an Internet Protocol Television (IPTV) access network. The channel selection data indicates a selection of an IPTV channel. The method also includes sending a rapid channel change (RCC) request to a distribution switch/router system via a subscriber virtual local area network (VLAN) associated with the set-top box device after receiving the channel selection data. The RCC request indicates the selected IPTV channel.

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.
