Abstract
Data encoded with a video clock is transmitted over a communication link in accordance with a communication reference signal, which in one embodiment is a wireless link. In one embodiment, the video clock is independent from the communication reference signal. The communication reference clock, which may be known to both the transmitter and receiver, is used to determine a frame period. On the receiver-side, the number of video cycles of the video data which are actually received are counted. The video clock may then be regenerated using the determined frame period and counted video clock cycles.
