| [iO] Pixelated
Ok whenever i switch to one of the digital discovery channels it's really pixelated than it clears up but when you look at stuff like rain or water on whatever show they have you can see it is still pixelated.
I was watching the sopranoe's on HBOW and when i looked at the wall it was all, weird lookin, like if i was watching a vcd or something of the show. Or like if you are watching something in DivX and you look at a wall.
And it's like this on every channel, it's especially apperant on Mtv Hits. What you guys think i should do?

| The Discovery channels all "draw" their picture when you first go to it. Takes like 2 secs to draw. Don't know why it's just those channels, but it always has been.
I don't see any issues like you describe on any other channels though.

It was like watching a VCD because youre essentially doing the same thing --- the digital channels are delivered in MPEG-2 digital video, which will at times deliver a certain amount of pixelation, depending on how much compression was applied to the signal... On a large TV, you can frequently see compression artifacts on dark areas that may see very subtle lighting changes, etc... Cablevision, for the most part, doesnt do too badly as far as compressing their digital video... I have read from previous Dish owners that CV seems to compress their channels less than DirectTV, but being that I never had DTV, I cant say for sure if thats true.
Oh, and all the channels that belong to Discovery, draw out with pixelation when you 1st tune them in... Dont know why that is, it just happens... Theyre fine to watch though.

Alright I'll guess i'll stick with it like this, but you sure you guys dont think i should call for some type of signal boost or somethin?

Your pixelation is due to low signal.
Get the wiring replaced/fixed. |

That's the pixelation I'm referring to. If you experience freezing and/or pixelation on digital channels, it's due to low or noisy signal. |

I have Dish Network and from time to time I have noticed the "pixelation" on dark backgrounds only. Not sure if pixelation is the proper term. In fact just today I was up on my roof and checked all of the coax connections on the switch. They were pretty loose so I tightened them all with a wrench. Not sure yet if it has helped. The picture quality all in all imo is still much better than anything CV ever brought into my home. Check all of your connections it might help or it just might be the way it is. Nothing is perfect.:)

The pixelation on the Discovery channels has nothing to do with signals. It has pixelation when you switch to it while it initially draws the entire screen. There's no pixelation or freezing once it draws the initial screen.

Are you talking about the effect where a background, such as a dark wall, which should have a smooth transition from dark to light (or from one color to another), instead has sharp transitions, as though it were a paint-by-numbers picture?
Kind of like the dark to light transitions on Ingrid Bergman near her hairline and on her right cheek here: »www.michaeldvd.com.au/Articles/V···ion.html
If so, those artifacts are called banding and posterization. They are caused by overcompressing the video stream, not by loose connections. |

Bichon, that's exactly what I'm talking about. Posterization. I've noticed it since I've had the dish. It realy is my only complaint. No else in my family sees it. Just perfectionist me.
By the way, I never knew until this week when my wife and I were visiting Greenport that Bichon is a breed of dog. One of the shops had these coffee mugs with various breeds of dogs on them and one of the mugs had a Bichon on it. It looked exactly like your avatar. The things I learn on bbr.
Cute dog. What do I know, I have two cats.;)

The mug you saw was probably one of these. Cat people are always mistaking him for a poodle. 
As for the banding/posterization artifacts, you'll notice them more on the "low rent" channels, and less on the premium channels like HBO and PPV movies. And like you say, most people don't notice them at all. |

Actually, I got the mug a few years ago while vacationing in Myrtle Beach, SC, in one of those stores that specializes in those "Sandicast" animal sculptures.
Oddly enough, although my mug isn't from Long Island, my dog is. Bought him from a breeder in Melville. |

Most of the digital channels do that, and obviously you know why, but to say it has nothing to do with signals is totally incorrect.
Go behind your digital box, and loosen up the cable in connector some. Then, wiggle it around, and tell me what happens. |

| Ray... do you have ioTV? Every other channel comes up instantly (digital or analog). The ONLY channels that draw for me and as far as I know, everyone else with ioTV are the Discovery channels. It does it on every set, for, as I said, everyone with io.
So unless everyone with io has issues with their signal and ONLY for the multiple Discovery channels, I respectfully tell you, that you have no idea of what you speak!

If "most" of your digital channels do that -- youve got some problems, and should probably get your own problems worked out.
Discovery-owned channels do it on first tune when drawing... IIRC, BET on Jazz does it as well. But like others have said, its only on the initial draw of the channels. I have never experienced any pixelated video after a channel has become viewable (maybe a 'glitch' -- but VERY rarely).
By the way, my signals always have been "pristine" -- very high S/N ratio on all my boxes, all receive levels centered around 0, upstream levels around 40. If you go into a Cablevision store and tune in one of the Discovery channels -- it will do the same exact thing - guaranteed.. Its something with the way the channels are fed into the system -- not due to signals.

Geek: I was one of the contractors rolling out iO in LI for Cablevision. I am a digital/hsi service tech in FL.
Darkmanx2da had a question about pixelation, but someone else (Bichon) pointed out that he was not really talking about pixelation, but banding and posterization.
We're basically having two different conversations here. I'm saying that if there's bad pixelation going on, it's due to bad or noisy signal. I'm not referring to first few seconds of tuning though, the reason we see a bit of pixelation there is because you're tuning into an MPEG stream in the middle of a frame update where the receiver hasn't yet received the full frame. This happens on the discovery channels in every system I've been in, including the Cablevision and the North Central Florida area, and even some DirecTV receivers.
Basically, we're having two seperate conversations due to a wrong term being used at the beginning. Bichon cleared it up. Noone is wrong, just a misunderstanding. Sorry.
Have fun.
