You need to recall that temporal compression of MPEG2/MPEG4 requires
time to buffer up and rebuild. You could even have at least two such
link, one from the OB-bus to the TV house, and another from the TV house
out to the transmitters. These days satellite is popular in the US for
transmitter feeds... not to speak of...
Looking at the TV and try to do timing is not very relevant. You should
get same minute, but not same second kind of offsets.
So, dropping the ball.. was someone there and compared to a sufficiently
accurate clock?
Cheers,
Magnus
