ABSTRACT:
The subjective quality of an audio-visual stimulus is measured by measuring the actual synchronisation errors between the audio and visual elements of the stimulus, identifying characteristics of audio and visual cues in the stimulus, and generating a measure of subjective quality from said errors and characteristics. The nature of the cue has an effect on the perceptual significance of a given value of synchronisation error, and this can be used to relax tolerances to such errors when appropriate, or to provide an accurate measure of the quality of the signal as it would be perceived by a human subject.
