Abstract
A method for objectively and non-intrusively measuring the audio-visual quality of a destination audio-video signal that generates measurement parameters that are indicative of human image quality perceptions. Subjective human test panel results are generated for a variety of audio-video test samples and objective test results are also generated by the apparatus of the invention for the variety of audio-video test samples. Accordingly, when the apparatus extracts test frames from the actual source and destination audio-video signals and compares them, audio-visual quality parameters are output by the apparatus that are indicative of the audio-visual quality of the destination audio-visual signal based upon the source audio-visual signal.
