HDTV at 4mbps?

What type of compression are they using? Mpeg 4? I know Comcast sends their HDTV at 19 mbps. It's hard to imagine the picture quality would be as good when it's that compressed. I'd be interested to see hear from users in San Antonio how it looks when it becomes available.

No way can it be 4Mbps.
From everything i've read about the technology they need at least 10Mbps and up to 20Mbps even.

That's right, there is a no MPEG-2 or MPEG-4 HDTV at 4 Mbps. Best one could hope for now is roughly 9 Mbps.

Can anyone report what brand STBs they are deploying?

I thought it seemed low , but that is what it says in Karl's article.

Karl, where'd you get that number from?

No you're right. I was repeating what one forum user claims he was told by an AT&T manager:

quote:
That's the pricing I heard from a manager in the new UVERSE (not EPC) department. He also stated that sd channels are streaming at 2 megs and hd channels at were streaming at 4 megs
I should have notated that was ridiculously optimistic.

In reality I've heard they're trying to squeeze two HD channels into 14Meg with overhead. I've also heard their HD solution is still far from where they'd like it to be.

Sure it can. They can use MPEG-4 and compress the feed. Encoders can do whatever they tell them to do.

While that is true, good looking HD (720p) is about 6Mbps. So, you are taking out a 1/3rd of the information to get it down to 4Mbps. It should be noted that 6Mbps is achievable only when compression on a computer. Real time would mean higher bit rates.
