AI summary

At one of a video source device and a video sink device, an indication of video processing capabilities of the other of the video source device and said video sink device is received. Based upon the indication and an indication of video processing capabilities of the one device, one of a plurality of video processing algorithms is selected for execution by the one device. The selecting may be based upon a set of precedence rules. Categories of video processing may for example include scan-rate conversion, interlacing, de-interlacing, de-noise, scaling, color correction, contrast correction and detail enhancement.
