摘要: This invention describes a system for video and audio distribution over the Internet. The Internet Convolution Audio/video Server (ICAVS) acts as a proxy Internet server for clients performing world wide web searches for video and audio. It delivers video and audio information in a format customized according to the client's system and communication constraints, and performs web crawling, video caching, and format conversion (when necessary). The proxy serving function reduces the requirements on the client's system for accessing video or audio in a variety of formats, in addition to reducing server storage requirements and Internet bandwidth.

摘要: A method and apparatus for scheduling the transmission of a number of data streams over a common communications link, where each of the data streams conforms to a corresponding set of flow control parameters. Each of the data streams to be transmitted on the communications link is stored in a corresponding queue. The status of each queue is maintained, and a target transmission time is calculated for each queue. Signals are then generated for each queue at a time at least after the target transmission time, and these signals are used to indicate to a corresponding queue that it can transmit a cell on the link. Upon reception of a corresponding signal, a queue then transmits at least one cell onto the communications link.
