Abstract
Disclosed is a method, circuit and system for transmission of video data between a video source and a video sink. A video source transceiver may include: (1) a video source interface for receiving video data, optionally including one or more video synchronization signals functionally associated video source device; (2) a video source clock sampler for sampling a video clock parameter of received video data; (3) a video data buffer for buffering received video data prior to transmission; and (4) a video transmission circuit including packet size timing logic adapted to generate and transmit to a functionally associated video sink transceiver a value correlated to an expected data packet size based on video data stored in the video buffer. A video sink transceiver may include: (1) a video reception circuit adapted to receive a transmitted data packet, including one or more values generated by the packet size timing logic, and to regenerate a video frame; (2) video sync signal generation logic adapted to regenerate one or more video frame synchronization signals based on the one or more values generated by the video transmission circuit, and (3) a video sink interface for forwarding r…
