Abstract: There is disclosed a method and apparatus for controlling the size of a jitter buffer in an audio receiver. The method an apparatus are such that network jitter can be distinguished from burst periods, where a large number of data packets (or packets) are transmitted rapidly. This method comprises the steps of monitoring the network for at least one burst period and then determining a likelihood for at least one subsequent burst period from this at least one burst period. The jitter buffer size is then adjusted based on the likelihood of this subsequent burst period. Apparatus for performing these method steps is also disclosed.

Abstract: Methods and apparatus for measuring network bandwidth are disclosed. These methods involve estimating present network bandwidth, transmitting test packets for measuring the available bandwidth, and adjusting the bandwidth, based on said measurement, by changing packet transmission bitrate.
