ABSTRACT:
A video system that determines an indication of interpolation errors for each of a set of available subsampling modes for encoding a target video frame that contains a set of pixel data values corresponding to an image scene is described. Each available subsampling mode provides a differing degree of subsampling on the target video frame. The video system determines a selected subsampling mode from the available subsampling modes such that the selected subsampling mode provides an attainable degree of subsampling with minimal loss in image quality.
