摘要： Methods of data streaming from an encoder to a decoder through a connection subjected to time-varying conditions are disclosed. The connection is assigned a nominal flow rate and an encoding coefficient associated with the connection modifies the nominal flow rate to determine a permissible flow rate compatible with a time-varying state of the connection. Multiple performance characteristics are associated with the connection and corresponding sets of performance measurements taken over adaptively selected time windows are acquired. Performance metrics having one-to-one correspondence to the performance characteristics are determined and compared with lower bounds and upper bounds of respective predefined acceptance intervals. A current encoding coefficient is computed as a function of the performance metrics and used to determine the permissible flow rate. The encoder's configuration is adapted to produce an encoded signal which maximizes signal fidelity under the constraint of the permissible flow rate.

摘要： A system and methods for adapting streaming data for transmission over a connection of time-varying capacity are disclosed. A streaming server individually adapts transmission rates of signals directed to subtending clients according to measurements characterizing connections from the streaming server to the clients. The measurements may relate to characteristics such as transfer delay, data-loss fraction, and occupancy level of a buffer at a client's receiver. A flow controller associated with the streaming server derives metrics from measurements taken over selected time windows to determine a permissible transmission rate from the server to each active client. Metrics related to a specific characteristic may include a mean value over a moving window as well as short and long term tendencies of respective measurements. An adaptable encoder at the streaming server encodes signals to meet permissible transmission rates.
