Pixelation Woes

Do you use an HDMI cable? when we were having ours installed the guy said that on some of the cable boxes that the HDMI cables don't work well and you have to use Component cables(red, blue, green) instead, it happened on the one in my room where it got pixelated, but we just got a new HDTV in our family room and it is going just fine with the HDMI cable. So some work and some don't

one HDTV on HDMI and the other is on Component and I saw it on both TV's

OCNBLUE - I also have the same issue as you...I have 2HD/2SD but am on the 19.2mbs profile. I've tried to explain to Tech Support that I should be on the 25mbs profile but they don't seem to get it.

On my low profile I can get by watching 2HD and 1SD but when I try to do 2HD and 2SD I get extreme pixilation on one of the HD streams.

I've heard from others that your max sync rate needs to be >30mbs to get the 25mbs profile. My max is right at the cutoff 29.9mbs.

Have you gotten Att to up you to the 25mbs profile??

reply to OCNBLUE
You guys definitely need to be on the 25mbps profile if you are on 2HD/2SD. The 19mbps profile is very new and it seems like they don't know how to deal with it yet. The proper profile for the 19mbps profile is 1HD/3SD. I'd try for the 25mbps profile first of course.

If you aren't having good luck with phone support, I suggest trying David over in AT&T Direct.

Your funeral. Delivered.

AT&T direct says I am on the right profile at 19/2 as does customer support. I have a tech visit today so we will see. Also one SD TV has a habit of getting stuck on an image and the audio just continues to play. AT&T has plenty of bugs to work out.

It seems like their FTTN is very limited. I have to give the nod to Verizon on this one. In 5 years they will dominate.

reply to OCNBLUE
The only advantage Verizon has is the pipe.

Anyway, if you give me the account numnber, ill look at it.

Mine works fine, 2hd/2sd never have a problem.

reply to OCNBLUE
I'd like to take a closer look at it anyway. I have a little more I can do from this end. If you dont mind that is.

I believe apeface works in the U-Verse NOC and may have access to more tools and abilities to make changes than David would. Give it a shot. Worst case he gives you the same info while the best case is you get your problem resolved. For all the good he does to help others, David doesn't have access to all systems. We like to make him call people sometimes too

Out of curiousity, are there specific HD channels which are giving you problems? I have 2 HDTVs in the house and since the upgrades earlier this year to fix the codecs for the HD streams, my problems have gone away. FWIW, I have 1 on HDMI and the other on component.

Ape I pm'd the acct number.

wolverine - we are pretty much on a few channels only. Discovery, SciFi and anything kid oriented. I have recorded Deadliest Catch and have to fast forward past the pixelation areas. My two plasmas are on HDMI and my Rear Projection is component.

technically if you are giving up 4/1 for the 2/2 you would lose the bandwidth of the 2 sd's and get 1 hd.

There are only 2 profiles, not matter what you order.

Just an FYI -

The tech came out and replaced 2 coax cables that were bad from the dish install.

Apefaced changed my profile to the other one and I have not seen any issues as of yet! woohoo!

We will see how this goes and I will let everyone know. Thanks for the feedback and the help everyone.

Apeface can you hook me up as well on the 25mbs profile? I posted above that I have 2HD/2SD but am on the 19mbs profile. My max rate is usually around 29.9mbs which should have enough headroom for the 25mbs profile. Let me know and I can pm my account #...Thx

I've got the 25mb 2hd/2sd tier, and I don't watch any HD channels (no HD service activated) since I don't have any decent displays. On a few of the movie channels (showtime, starz) I'm constantly seeing pixelation. Seems kinda ridiculous to see it on SD channels. This is, of course, before the entire U-Verse network died on me this morning

reply to djrobx
There are 2 profiles, 25/2 and 19/2. 25/2 is default on every line. 19/2 is for the ones with issues. Everything else is handled by QoS filters. If you have a crap line, they most likey arent going to let you order elite or max, but you can still get 2/2.

reply to OCNBLUE
I cancelled my U-verse TV due to compression artifacts and pixelation on both SD and HD. My Comcast HD signal was clearly better in sports and action scenes, not perfect just better.

I contacted AT&T about the issue and they didn't seem to care and happily let me go. I'm on the 25mbit profile as well and have 10mbit MAX Internet.

AT&T is doing a lot of compression and using low bitrates on video to achieve 2SD and 2HD over the 19/25mbit channel. To get higher bitrates and better quality they'll need to go a higher profiles with VDSL. I'm across from the VRAD so my line can achieve much more, so if AT&T ups their quality I'll probably go back.
