dlp - satellite - issues !!

[CheeeZ]

Hello ALL !!

I have recently upgraded my home theater, and I have a few questions. I have replaced my Mits 6083, with Mits 62 dlp. Replaced my Yamaha rx-v2090 with Pioneer Elite vsx-53tx. I have a Pioneer DV-F727 disc changer, using component video. I have Directv satellite, round dish, dual lnb, with an RCA dwd490re receiver, using s-video.

When veiwing a dvd the Mits picture is better than looking out the window !! absolutely stunning. Monsters Inc. is my favorite example. As for viewing tv, I am in a quandry. I realize s-video is not going to be as good as component, but how much of the picture reproduction is actually effected by that? Anything i watch from the sat. has pixelation i.e. (think of viewing a piture of Maui in 16 colors) I can see the transitions of say a light in the background going from white to gray to black. Pixelation in skin tone is also bad. I will say some channels are better than others. Which brings me to my next question, the signal strength. Most signals I get are betweeen 90 and 98%. I have read anything over 70% you can't see the difference. So is it just the s-video that degrades the video signal, or what? I want to upgrade to HD but I don't want to pay for a new receiver and the service if I am still going to see the same pixelation.

If anyone has this effect, any help or guidance would be greatly appreciated.

Thanx-
CheeeZ

Ditto!!!

sorry I can't answer this question for you...but I can tell you I have the EXACT same issues running through a Toshiba DLP, a Harmon Kardon receiver and dvd and a bell satellite system....anxious to see the responses you get.

I've seen the same, and I chalk it up to the television.

I'm not sure why technologically, but the signal provided by broadcast TV (unless in HD or unless you have an HD tuner) does not come in well on certain televisions.

I was watching some football at my friends house last week. DirecTV Sunday Ticket. He has an HD tuner, but alas, one of the games we watched was not in HD. It looked like GARBAGE compared to the HD game. Pixelation and lots of "noise" in the picture.

Not sure whether this is the mechanics of HD vs. non HD or the way the TV "interprets" the broadcast signal.

I know that some TVs have a better broadcast signal picture than others.

I don't have any of the components you have. Maybe this will apply, maybe not.

What I have is noticed is that the components doing the scaling impact this type of picture quality issue. Oddly, I do see a difference in s-video and component connections that isn't just related to quality of the video signal. Rather it seems the scaling must treat these connections a little different.

Short, story - try switching from svid to component and see if it makes a difference. Also, if the set top box (STB) lets you scale the resolution try setting this to fixed at 720p and 1080i to see if you can a better picture without artifacts with one or the other.

Here's the background on what I found:

I have a STB for HD that looks really bad when feeding an SD broadcast upscaled to 720P to an optima projector with 1080 lines. Lots of jaggie edges and sort of a diamond pixelation of everything moving that kind of resolves when motion stops. But, the same STB doing 1080i upscale to the projector of the SD broadcast looks much better.

On the flipside, when the STB scales down a 1080i HD broadcast to 480i over the s-video the picture is diamond pixelated again.

By experimentation, I found by feeding component for the SD TV that the pixelation for down scale of 1080i to 480i went away, and fixing the STB to always scale to 1080i not matter of the content resoultion on DVI took care of the projector PQ issue.

If you are having problems with standard broadcast TV stations via cable, your problem is the standard Tv signal, especially on larger sets. It just doesn't have the resolution and is less than on a DVD to boot.

Now, if you are having problems from hi def programs, perhaps the cable company or your service is insufficient to give you the high quality pictures?

Garbage in = Garbage out

Garbage in = Garbage out

That's helpful!

Well thats pretty much what it amounts to, SD signals are of poor quality, satelite providers compress the video signal on top of that and what you get is of even less quality, if you are watching via a DVR recording it's been compressed again. Cable is no better. You have to realize your trying to display an image using more pixels than what is provided and it has to come up with them from somewhere and this is what gives you that pixelated look. You can take a 640x480 image on a computer monitor and blow it up to 1600x1200 and it looks like garbage. Now, if you were to take a 1600x1200 image (native) it will look much better as it is not artifically creating pixels. Now take DVD for example it is also 480, but it has not been compressed and more than likely will be progressive which will reduce the pixelization you are seeing but will not look as good as high def. So to sum it up, garbage in = garbage out.
