Abstract:
A method is provided for synchronizing a source device with a sink device. The source device transmits a stream of packets to the sink device. The source device receives feedback from the sink device indicating packet arrival times of the packets at the sink device. Based on the feedback, in some aspects, the source device determines an average time shift in the packet arrival times at the sink device, wherein the average time shift is relative to expected packet arrival times of the packets at the sink device. In some such aspects, the source device detects that the average time shift exceeds a threshold, and in response to the detecting, adjusts a streaming time of the stream of packets to synchronize, within a predefined tolerance, the source device with the sink device.
