Apparatus for adjusting a local sampling rate based on the rate of reception of packets

摘要

A packet network interface for delivering streaming data to an analog output is described which can compensate for a sampling rate mismatch between the far-end transmitter and the local receiver by monitoring the rate of reception of packets and adjusting the local (receive) sampling rate responsive to said rate of reception. Typically, the rate of reception of packets is monitored by monitoring the level of a jitter buffer used to compensate for variable delays in the rate of reception. If the average level is too high or two low, this is a likely indication that there is a rate mismatch between the far end and local sampling rate. Adjustments are then made to the local sampling rate to adjust for such a mismatch.
