Abstract:
A method minimizes audio and video streaming delays between a video source and a video sink. A receiver receives a netsync message from a transmitter that communicates with the video source to receive input video. The netsync message is generated by the transmitter in accordance with the input video and indicates a display pointer of the transmitter. In accordance with the netsync message, the receiver adaptively outputs a set of timing control signals that is transmitted to the video sink, thereby minimizing the latency between the vertical synchronization (VSYNC) of the transmitter and the VSYNC of the receiver.
