Abstract
A method of measuring the video quality on display devices of differing types and/or sizes based on a known display type and size, said method includes the steps of: (a) obtaining a subjective quality score of video sequences viewed on a first display device; (b) obtaining an objective quality score of the video sequences in step (a); (c) obtaining a subjective quality score on a second display device, wherein the second display device having at least one difference in size and type than the first display device; (d) estimating an objective quality score for the second display device based on a correlation between the subjective and objective scores of the first display device, and the subjective score of the second display device. An apparatus and system provide hardware and modules to permit the measurement of video quality and optional fine tuning of the video quality of the second display based on the objective video quality scores.
