1. A method of apportioning desired video processing between a video source device and a video sink device, the method comprising, at one of said devices: based upon an indication of video processing algorithms of which the other of said video source device and said video sink device is capable and an indication of video processing algorithms of which said one device is capable: identifying a set of video processing algorithms for achieving desired video processing; and classifying the video processing algorithms of said set into a first subset of video processing algorithms for performance by said other device and a second subset of video processing algorithms for performance by said one device; and sending at least one command for causing said other device to effect the first subset of video processing algorithms.
