Abstract:
The methods described herein are configured to correlate frames of a video stream to a system clock. A correlator application receives a frame of a video stream from a capture device via a bus interface, the frame including start frame and end frame timestamps based on a device clock of the capture device. A second start frame timestamp and second end frame timestamp are predicted based on previously received frames and a system clock. A skew value of the frame is calculated based on differences between the start frame timestamps and the end frame timestamps. Upon the calculated skew value exceeding a skew threshold, the frame is corrected to correlate to the predicted start frame and end frame timestamps. The corrected frame is then provided for display. Correcting timestamps of video stream frames in the described manner reduces jitter and enables accurate synchronization of multiple video streams.

Claim (Index 19):
The one or more computer storage media of  claim 18 , wherein the computer-executable instructions, upon execution by a processor, further cause the processor to at least:\n receive frames of a second video stream from a second capture device; timestamp the received frames of the second video stream; combine the video stream with the second video stream; and wherein the corrected frame is synchronized with a matching frame of the second video stream.
