Greetings -- I am trying to determine the requirements on lip synchronization
for applications such as video conferencing.  Specifically, I am looking for
some references on human perception of the synchronization of audio and video.
Ideally I'm looking for published studies in either the human perception or
perception and psychophysics literature that deal with this topic?  For
example, can people tell if audio is say 50ms. ahead or behind the video (and
does it bother them)?

Thanks...
