Abstract
A clock rate used in rendering broadcast streaming audio/video data is adjusted to converge on a clock rate associated with broadcasting the streaming data. The clock rate is adjusted by monitoring the buffer depth associated with a receive buffer that stores the incoming streaming data. The buffer depth provides an estimate of clock drift between the two clock rates. From the estimate of clock drift, the clock rate used in rendering broadcast streaming data is adjusted to avoid the clock drift causing skips or pauses in the rendered audio/video data.
