Data Streaming Through Time-Varying Transport Media

摘要

A method of data streaming from an encoder to a decoder through a time-varying connection, is disclosed. The method includes associating an encoding coefficient with said time-varying connection, the encoding coefficient determining a flow rate at an output of said encoder; defining a performance metric of the time-varying connection; defining an acceptance interval of the performance metric having a lower bound and an upper bound; acquiring a set of performance measurements of the time-varying connection over a time window at a current encoding coefficient; determining a current value of the metric of the time-varying connection according to the set of measurements; determining a preferred encoding coefficient according to the current value of the metric; and modifying the current encoding coefficient based on the current value of the metric and the acceptance interval to attain the preferred encoding coefficient. A corresponding streaming server and system for data streaming are also provided.
