Abstract: The quality perception of an audiovisual sequence is heavily influenced by the quality of the audio, the quality of the video, and the audiovisual time synchronization. The questions then arise: what is the relative importance of each factor, and can a model be devised that is generally applicable? Previous work either examined the relative influences of audio and video quality for synchronized video or investigated the quality impact of synchronization errors on unimpaired video sequences. This experiment is a first attempt to combine all three factors into a single experiment, to judge the complex interactions among individual measurements of audio and video quality and synchronization errors.
Keywords: video quality; synchronization; audio quality; subjective testing; audiovisual quality
