To me the ball drop/fireworks was different from the on-screen time on FOX
by a few secnds.
I was watching the media pool HD satellite feed on AMC-1 and
through a broadcast grade IRD (ex PBS Bitlink ) it appeared to be about
2 seconds slow relative to my house NTP timing. This would about
exactly match what I would expect for uplink encoder, satellite path,
and decoder delays.
I would expect a TV station using that feed might add anywhere
from 1-6 seconds to the delay in their internal processing to OTA... and
a digital cable system might add further delay to that (couple of more
seconds at least).
Real time TV these days is only RELATIVELY real time.
When doing interviews on live TV across the atlantic, using uncompressed
video and audio have been used to avoid the anoying delays.
But the highly technical world now has more delay than we used to.
Progress... :P
Cheers,
Magnus
