Pixilization on ota WRGB

[econ]

Since the start of the NCAAs I have been getting pixilization on the right side of my TV(Hitachi 50v500) screen during WRGB's(6-1) HD broadcast but none for non HD broadcasts.I have no such problems with any other OTA stations. I e-mailed Fred Lass at WRGB and he almost immediately replied that they did change the configuration in their encoding equipment to add subchannel 6-3. He then said that it seems to effect only Zenith equipment. I have a Zenith HD receiver. Does anyone else have a Zenith receiver or HD tv
who is having this problem. And if you do , please don't adjust you tv sets(antennas) yet. The problem is not on your end.

I have a Zenith(LG) DirecTV/OTA STB... the SAT520 model. I didn't use it to tune the tourney however. It's my backup STB, since VOOM is my current provider.

Did they correct the problem? Does it happen when 6-3 is dead?

Here is what Fred replied... I suspect when 6-3 is removed things will go back to normal.
"I'm going to out on a limb and guess that you have a Zenith HDTV. I also
have one and mine did the same thing. I have the 34" direct view CRT
receiver model C34W23. We also have an identical one here at the station
that also pixilated in the same way. I have not seen or heard of the same
problem on other HD sets. I do not believe that it is caused by a reception
problem.

I don't know what is causing it, but it's likely a design problem with the
decoder module inside the TV set. The module itself is made for Zenith by
its parent corporation, LG Electronics in Korea.

This was the first time that I've seen this pixelization on my TV. We'll be
investigating to see if there is anything that we can do differently in
order to avoid this problem with our receivers. I'll be talking with Zenith
and LG to see what else I can learn. Did you notice that it happened more
often when the camera panned right than when the action was moving left?

The next question is why did it start during Basketball? I'm assuming that
it was triggered by a change in the configuration of our encoding equipment
coupled with the high motion scenes of the camera panning. In order to
carry three games, one in analog, one in HD and a third on our 6-3
subchannel, we reconfigured the bit structure to favor the high motion in
Basketball. The video quality of UPN on 6-2 suffered whenever there was
high motion in 6-1. (Sorry, WWE) We have been running this variable bit
rate equipment since December with no bandwidth assigned to 6-3. I'll be
watching CSI this week and other shows with action to see if the problem
recurs. The variable bit rate scheme makes room for the third subchannel
without impairing the picture quality of the HD signal. If that is the
source of our Zenith problem, it'll take a factory expert to know for sure.

We're on the bleeding edge together, please have patience."
