In this paper, we describe three psychophysical experiments with the goal of understanding the influence of audio and video components on the overall perceived audio- visual quality. In Experiment I, subjects evaluated the quality of videos (without any audio) compressed at different video bitrates. In Experiment II, subjects evaluated the quality of audio (without any video) compressed at different audio bitrates. In Experiment III, subjects evaluated the quality of videos (audio- visual signals), which had their audio and video components compressed at different bitrates. The results of these experiments show that compressing only the video have a higher impact on the overall perceived quality than compressing only the audio. Another important goal of this paper is to propose an objective model for the audio-visual quality. Using the gathered data from Experiments I, II, and III, we are able to obtain two models with reasonably good correlations with the overall perceived quality.
