is "pixelation" & why do I see it on my TV?
the form of small blocks moving rapidly within the picture. Some call
it the" jigsaw puzzle"
effect. It occurs when the incoming signal to your TV is weak
or incomplete and can be caused by
occurring in the TV studio, the satellite up-link/down-link chain, our
system, or even receiving components such as your antenna, coax
cable or splitters.
the pixelation occurs nearly
time, on one or more digital channels, the signal is
weak . Please see our other FAQ items on antennas, splitters
etc., for ways to improve it.
pixelation happens infrequently then
the problem is probably in the studio/satellite distribution
system and beyond our control.
the pixelation occurs simultaneously, on all
the channels on a single transmitter (ie. 32.1, 32.2,
then the problem is ours. More channels
means more data. If there is more data to be sent
than the transmitter can carry, some data will get lost and the result
try to mix and match programs to
minimize pixelation but the amount of data needed changes by
scene and by
program. The problem is a bit like herding cats. Experience has shown
three channels on a transmitter is a reasonable data load; with
minimal pixelation. So most of our
transmitters carry 3 channels. A
few transmitters carry four; where two or more of them are
have small data streams. We do everything we can to minimize the
problem, but cannot totally prevent it.
And no, pixelation is not caused by
