Abstract
A method, circuit and system for transmission, receiving and processing of video data between a video source transceiver and a video sink transceiver. Video data or information to be transmitted, which instructs an image processor associated with a video sink to modify a previously video frame into a current frame. A Delta Frame may include one or more Grid Based Predicted Error (“GBPE”) Values. The GBPE may be generated by source-side image processing logic using processes or techniques similar to those described in the MPEG and/or H.264 Standards, with the exception that the prediction error values may be calculated relative to a noisy predicted frame (e.g. based on an analog reception of a base frame) which has been grid quantized based on video sink transceiver SNR (e.g. substantially each pixel value in the predicted frame is rounded off up or down to a value on some grid).
