plasma shimmer

I have an Hitachi 42HDS69 plasma tv. I watched the playoff games in HD
through Comcast Cable. I live in Wheeling, WV which is in the Pittsburgh
region. The teams in white uniforms with light numbers and stripes on them
produce a shimmer from the stripes and numbers when the whole field of play
is displayed. This was the New England and Colts game. This was a network
game. I watched the Bears game and didn't have any picture quality problems.
It was on Fox. I tried some adjustments in contrast and tint and
brightness. None of these made a difference. Is this a network broadcast
problem or a problem with the tv? Any help would be appreciated. Thanks

Aliasing is shimmer in the video image, and is fundamentally an artefact of
interlaced video. Sharp lines and fine details in images are affected, and
shimmer whenever there is movement. The typical image components that show
aliasing are; venetian blinds, automobiles with lots of chrome, automobile
grilles and finely detailed images of greenery. Aliasing does not show up
until these elements are in motion, so it is typical to see a finely
detailed image periodically shimmer whenever the camera pans, particularly
in a diagonal direction.

Not your TV.

Video compression from your cable company. I've seen it on both SD and
HD digital broadcasts. (Get used to it)
