        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.
