The small TV set in the kitchen might be CRT while the big one in the
living room is LCD (or any similar flat screen), and for the later
double-buffering (or more) is employed as standard. These new screens
are "slow" and create tons of artefact with standard definition TV or
just the wrong rate.
Doing low-delay uncompressed transmission across countries, continents
or between them is all at vain, when the flat-screen comes into the
loop. It is often impossible to disable it.
