Patent ID: 8104055

Claim:
A method of identifying a target synchronization point pair including a source synchronization point corresponding to a source end and a destination synchronization point corresponding to a destination end, the method comprising: utilizing the destination end for receiving a source scan-line image corresponding to a first video source from the source end, wherein the source scan-line image is created by extracting one scan-line from each frame of the first video source, the first video source having a plurality of frames and the created source scan-line image comprising a plurality of scan-lines; utilizing the destination end for selecting at least a comparing frame out of the source scan-line image; utilizing the destination end for providing a destination scan-line image corresponding to a second video source at the destination end, wherein the destination scan-line image is created by extracting one scan-line from each frame of the second video source, the second video source having a plurality of frames and the created destination scan-line image comprising a plurality of scan-lines; and utilizing the destination end for determining the target synchronization point pair by comparing the comparing frame and the destination scan-line image and finding matching image correlation values.
