Patent ID: 8432804

Claim:
A method of transmitting video streams, comprising: coordinating transmission of intra-frames in a first video stream with transmission of intra-frames in a second video stream over a shared transmission line; transmitting intra-frames in the first and second video streams such that the intra-frames do not overlap between the first and second video streams during substantially simultaneous transmission of the first and second video streams over the shared transmission line; staggering initiation sequentially of the substantially simultaneous transmission over the shared transmission line of the first and second video streams by a number of frames proportional to a group of pictures size divided by a number of video streams in the first and second video streams; and maintaining synchronization of the transmission against potential clock drift in each of the first and second video streams such that the intra-frames within the first and second video streams do not overlap during the substantially simultaneous transmission of the first and second video streams over the same transmission line.
