Abstract: In a streaming media system, a client device includes an adjustable-size jitter buffer to buffer audio packets of a stream. A buffer controller of the client device operates to determine a representation of a current condition of the network, such as through statistical analysis to generate a histogram or probability density function representative of measured differences between arrival times of successive audio packets at the client device, either since a start of a streaming session or over a sliding time window. The buffer controller then selects an updated size for the jitter buffer based on the representation of the current condition of the network and implements the updated size, either in one adjustment or over time at a size adaptation rate based on a programmable adjustment duration, so as to balance buffer latency and dropped packet rate in view of the current network conditions.
