摘要： A Video Server (VS 100) encodes a video stream according to the values of parameters and transmits the video stream over a Network (200) to a Video Client (VC 200) that decodes the received video stream for presentation to a user. As the video stream is being received, (VC 200) continually gathers data regarding at least the condition of Network (200) sends this data to (VS 100). (VS 100) modifies the values of the parameters based on the data received from (VC 200), which in turn modifies the encoding of the video stream.
摘要翻译：视频服务器（VS 100）根据参数的值对视频流进行编码，并通过网络（200）将视频流发送到视频客户端（VC 200），视频客户端（VC200）解码所接收的视频流以呈现给用户。随着视频流被接收，（VC200）至少连续收集网络（200）的条件的数据将该数据发送到（VS 100）。（VS100）基于从（VC200）接收的数据来修改参数的值，其又改变视频流的编码。

摘要： An apparatus and a method for managing service traffic in a communications network capable of providing voice, data, and A/V services to a plurality of customers. In particular, the present invention is a digital subscriber line system (DSL), preferably based on ADSL, having a plurality of customer premise equipment (CPEs) coupled to voice, data and A/V services via network system equipment comprising a DSLAM, an ATM switch and a DSL terminator for connecting the system to the internet. The invention provides a network control system that includes a plurality of databases including a provisioning database and a real time database indicative of the actual bandwidth being utilized. A service control processor coupled to the plurality of databases and the network system equipment periodically polls the databases to determine the amount of bandwidth being used, and if the usage exceeds a predetermined level, throttles the internet data entering the system through the DSL terminator and/or the user data entering the system through the CPEs. Preferrably, throttling is performed using a leaky-bucket algorithm. By dynamically managing the traffic flow in the network, the present invention reduces the potential for dropped calls and similar service restrictions.

摘要： An asynchronous transfer mode (ATM) digital document delivery system is provided. A customer premise unit (2) is configured to permit a customer to order and receive a data stream. A buffer (34) is coupled to the customer premise unit (2) to store the data stream before transmitting the data stream to a customer. A server (22) includes digital documents stored thereon for delivery to customers through a switched ATM network (100). A control mechanism (11) is employed to control a data rate of the data stream between the server (22) and the buffer (34) to ensure maintenance of a steady data stream from the customer premise unit (2) to a customer during a loss of a physical layer between the server (22) and the customer premise unit (2).
