Abstract
Methods, systems, and devices are described for media synchronization. Multi-stream media processes may include media streams captured with respect to different clock rates. Multi-processor implementations may involve separate clocks associated with different media streams, such as audio and video, respectively. The separate clocks may tend to drift from one another, becoming further out of sync as time passes. Selecting a reference time of one of the processors to function as a 'wall clock,' recording frame capture times with respect to the reference time, accounting for propagation delays, and transmitting frame capture times in terms of the reference time may aid in AV synchronization at a device where audio and video streams are received.
