DATA STREAMING THROUGH TIME-VARYING TRANSPORT MEDIA |
摘要 |
<p>PROBLEM TO BE SOLVED: To provide methods of data streaming from an encoder to a decoder through a connection subjected to time-varying conditions.SOLUTION: 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.</p> |
