Mark A. McFarland et al.

Abstract: NTIA/ITS has conducted a series of studies to quantify the effects that individual audio and video qualities have on the overall Mean Opinion Score (MOS) for a given set of audiovisual clips. The experiment described in this report studies the effects that the synthesis of audio and video quality has on a subject's overall MOS. The overall MOS for this set of audiovisual clips can be predicted rather well from the video MOS alone. This appears to be a consequence of the wide quality range spanned by the video impairments, in combination with the narrow quality range spanned by the audio impairments. This result will not necessarily be valid for other choices of audiovisual material.
