Abstract
The dynamic streaming of multimedia data between a data server and one or more clients is disclosed. Dynamic streaming enables the rapid and accurate characterization of the end-to-end path conditions in a server-client streaming session, as well as the rapid and intelligent response to those conditions in terms of source compression prior to data packetization. The most significant bits of an original bit stream can be adaptively and immediately selected in response to network conditions. The adaptive selection process is informed by feedback from the client receiver indicative of a time-to-transit the network from server to client. A control protocol and server architecture, including file format, data structure, data processing procedures, cache control mechanisms, and adaptation algorithms useful in implementing dynamic streaming are also disclosed.
