There are digital filters and delay's which 'could/should?' be added
to these devices to compensate for the lag-time of one signal.

It's similar to what they use in very large Audio PA systems when
having very long cable runs.


I even notice it when I go to my doctors, the surround speakers have a
few hundred ms delay over the TV speakers which is quite disturbing.


The mathematics involved however to 'auto-sense' something like that
however is quite complex so even on YouTube videos for Sports like
NASCAR et el.... I have to always adjust the speach delay manually in
mplayer as it fluctuates.


It is quite an interesting scientific phenomenon though, signal
delay/lag and propagation through different mediums.
