Network synchronization video for composite video streams

A method comprising:

• receiving at a video capture device a control signal configured to indicate an adjustment to a video capture frame rate of an image sensor during capture of a video stream;
• and
• adjusting the video capture frame rate in response to the control signal to advance or retard a first vertical synchronization point associated with a first video stream by controlling the image sensor of the video capture device,
• wherein the control signal provides control information based in part on a difference in time between the first synchronization point and a second vertical synchronization point associated with a second video stream.

An apparatus comprising:

• a network interface unit configured to receive a plurality of video streams comprising at least first and second video streams;
• a processor configured to be coupled to the network interface unit and configured to:
• determine first and second vertical synchronization points associated with the first and second video streams, respectively;
• compute a difference in time between the first and second vertical synchronization points;
• generate at least one control signal configured to change a video capture frame rate of an image sensor used to generate one of the first and second video streams to reduce the difference in time;
• and
• send the control signal via the network interface unit to a video capture device comprising the image sensor used to generate one of the first and second video streams, wherein the control message is configured to control the image sensor of the video capture device.

A non-transitory computer readable medium storing instructions that, when executed by a processor, cause the processor to:

• receive a plurality of video streams comprising at least first and second video streams;
• determine first and second vertical synchronization points associated with the first and second video streams, respectively;
• compute a difference in time between the first and second vertical synchronization points;
• generate least one control signal configured to change a video capture frame rate of an image sensor used to generate one of the first and second video streams to reduce the difference in time;
• and
• send the control signal to a video capture device comprising the image sensor used to generate one of the first and second video streams, wherein the control message is configured to control the image sensor of the video capture device.
