Abstract

Video data is transmitted from a video source to a video sink via a fixed rate serial link with a substantially constant unit interval for transmission of each symbol of the encoded data. The unit interval of the serial link is maintained substantially constant, and does not vary regardless of the display parameters of the video data. The video data is encoded into a plurality of video data streams, with each data stream including a plurality of fields. The fields include at least a clock offset field and video payload data fields. The clock offset field includes phase information indicative of the phase of the display clock offset with respect to a time reference, indicated in terms of the number of unit intervals offset from the time reference. The video sink recovers the display clock based on the display clock offset information, and thus no display clock itself is transmitted from the video source to the video sink.
