I find this to ne interesting.

There is no doubt about it, these bitrates are low for HD. Here's a comparison of bitrates and quality on several HD video sources:

Cable: 1920x1080i/59.94 @ 12 Mbps MPEG-2 (bad)

U-Verse: 1920x1080i/59.94 @ 6 Mbps H.264 (not good )

OTA: 1920x1080i/59.94 @ 15 Mbps MPEG-2 (decent)

AVCHD: 1920x1080p/24 @ 10 Mbps H.264 (nice)

Blu-Ray: 1920x1080p/24 @ 25 Mbps H.264 (pristine)

U-Verse's 6 Mbps H.264 would seem to be equivalent to Cable's 12 Mbps MPEG-2 by the thumbrule above, but H.264's artifacts are less objectionable than MPEG-2. MPEG-2 starts to just break into the (very) noticeable macroblocks when starved for bitrate, but H.264 hides them much better. We get the shifting background, the color banding, and the inaccurate luminance and color in dark picture areas, but we don't get the macroblocks


the audio drop outs on u-verse wont be fixed untill at least aug 2010 was the last i heard but they are working with dolby labs on a possible fix. i too get the audio drops and miro blocking when there is a lot of fast movement if i were a sports fan i would cancle cause it is more noticalbe when watching sports...

I seem to be learning more about UVerse than I want to...

The number of possible HD streams is dependent on what region you are in- so it is very likely, in your area, only 1 is available.

The good news is they have over 250 adult movies on demand...or so I hear...
ParadigmDawg,

I was told after I asked several times, that in my area they could only support one HD per uVerse per household. But what you say makes more sense; I mean the fiber optics bandwidth itself wouldn't be the limiting factor. The uVerse salesperson was probably misinformed.

Thanks for your comment.

Peace, Good Sound and Good Video,

Forest Man

I get the rest, but what do mean by AVCHD? AVC is advanced video codec - basically different name of h.264.....

The bad news is, you get burned out on adul films after so many.

The good news, that number is in the tens of thousands. And it's temporary.

So you're saying my Comcast (which I'd like to replace, probably with Dish) is not 1080P? Time for a call. Where is Dish on the chart?

if there is one thing i know alot about on here it is digital compression, 12mbps is good for 480i at 30fps using mpeg-2 let alone 1080i at 60fps, terribly blocky and many fine details are compressed out. 6mbps on h264 is OK, h.264 is based on similar principles as divx, which has a transparency ratio that 1/10 of mpeg-2, ive seen DVD quality movies encoded at 700kbps using mpeg-4 type codecs (h.264, divx etc) compared to 7 mbps using mpeg-2. i would say 6mbps is decent for HD. when it comes to getting dish network if your worried about picture quality i would say dont do it, i was watching a large HD display on HD channels today at radioshack hooked up to a dish receiver and it was very blocky and compressed looking, comcast has very good compression ratios if you can stand their dumb-*** customer service reps, im watching an HD broadcast right now and i cannot notice any compression artifacts at all.

I'm not saying much of anything, just copying and pasting what someone else said in the UVerse forum...:p

i get full 1080p from them, even though my TV is 720p so i cant actually use it.
