Huntsville AL. Knology 1080i looks like a mosaic

Hi all.

Was wondering if anyone could tell me why when watching 1080i programs if there is fast moving stuff on the screen it looks kinda blocky like a mosaic? I used to think that it was just the i vs. p issue, but after the patriots game the other day, all the confetti blowing across the screen after they won made the whole screen do the mosaic thing. This never happens with 720p signals.

I'm fairly confident it's not the TV - it's a brand new Panasonic 42PZ77U and has 1080p capability. I'm leaning towards signal problems here. Anyone else have similar experience with Knology in Huntsville AL?

Actually, it is the problem from switching the interlaced signal to progressive that is making the mosaic look. Any noticeable movement from an interlaced source on a progressive player will five you that look. Thus, from all the confetti blowing around, your image looks completely fuzzing/blocky.

I suggest looking at your TV manual to see if there is anything to help with it, as an option that helps smooth the image out. Otherwise you may have to get a external de-interlacer.

I really hope your wrong. For what i spent on the TV I would expect it to have a good de-interlacer built in.

I'm not positive, but I'm pretty sure I don't get the same problem w/ my upconverting DVD player set to 1080i. I'll do some more testing though to check it out. If everything looks great w/ the 1080i DVD player, than it can't be the TV, right?

It is not your TV it is the signal being supplied which is compressed a little too much. Complain to your cable or sat provider. Please disregard what the previous poster said as it is incorrect.

Thanks, loves2watch.

It occurs to me that SD would look bad too if it was the TV. Guess I'll have to wait for Knology to improve their signal. In the mean time I'll see if any of those fancy image enhancing features built into the TV can help.

I have to agree with loves2watch. I watched the game on my 1080p display and it was perfect. It was a signal not an i to p problem.

Agreed. It also is a side effect from broadcasts that cram additional subfeeds into their local HD signal. That takes bandwidth away from the HD stream. I rarely see it here except on my 2 locals that have 2 & 3 subfeeds. On those, fast motion or movement causes blocking. On the rest that have no subs, then motion is clear.

Subfeeds should die (but they see them as another ad revenue stream)
