Abstract: Disclosed are a node distribution method and control center, the method comprising: receiving a scheduling request message sent by a UE; according to the scheduling request message, checking whether the UE is in a predetermined set; if yes, then checking whether the bandwidth of the node configured for the UE is occupied, and obtaining the check result, the node being a preferred node preconfigured for the UE; according to the check result, scheduling the UE to access the preferred node or other nodes. The node distributing method and control center provided in the present invention can balance the pressure between nodes, preferentially use resources, improve the quality of service of nodes, and increase website response speed.

Abstract: A system and method for transmitting and presenting streaming digital information signals that optimizes performance in the context of goodput, throughput, delay, receiver buffer requirements and tolerance to loss and jitter. The method provides ordering packets of information based on a priority associated with each of the packets; managing the flow of the packets into and out of a buffer; adjusting the rate at which the packets are provided to a communication medium; and transmitting and retransmitting the packets as needed.

Abstract: Methods for performing ad insertion prior to performing statistical multiplexing on one or more digital video streams including programs are disclosed. Select coded frames of a program and an advertisement are decoded and re-encoded at a predetermine bit rate to obtain a revised program representing the original program with the advertisement inserted at a select time.

Abstract: Methods and systems for integrated transcoding on a plurality of data channels to convert one or more data channels from an incoming encoding format to an outgoing encoding format are disclosed.

Abstract: A method for content delivery comprising transmitting content via a first network to a content aggregation point and transmitting the content from the content aggregation point via a second network to a receiver at the request of the receiver. A system for content delivery comprising a content provider, a content aggregation point operatively coupled to the content provider via a first network wherein the content aggregation point receives content from the content provider, and a receiver operatively coupled to the content aggregation point via a second network wherein the receiver is configured to request content from the content aggregation point. Also disclosed are methods for improving the network functionality through in-band measurement of network statistics, multi-constraint based QoS routing, and back up path determination.
