Abstract: ITS is conducting a series of studies to quantify the effects of the separate audio and video compression qualities, and the differential delay in their synchronization, to the perceived aesthetic quality of a multimedia signal. The experiment described in this report was specifically designed to study the effects of the differential delay.

Keywords: subjective testing; audio delay; audio offset; differential delay; multimedia quality; audio-video synchronization
