[Nanog] ATT VP: Internet to hit capacity by 2010

Tue Apr 22 01:35:45 UTC 2008

I've found it interesting that those who do Internet TV (re)define HD in a
way that no one would consider HD anymore except the provider. =)

In the news recently has been some complaints about Comcast's HD TV.
Comcast has been (selectively) fitting 3 MPEG-2 HD streams in a 6 MHz
carrier (38 Mbps = 12.6 Mbps) and customers aren't happy with that.  I'm not
sure how the average consumer will see 1.5 Mbps for HD video as sufficient
unless it's QVGA.

I'm going to have to say that that's much higher than we're actually
going to see.  You have to remember that there's not a ton of
compression going on in that.  We're looking to start pushing HD video
online, and our intial tests show that 1.5Mbps is plenty to push HD
resolutions of video online.  We won't necessarily be doing 60 fps or
full quality audio, but "HD" doesn't actually define exactly what it's
going to be.

Look at the HD offerings online today and I think you'll find that
they're mostly 1-1.5 Mbps.  TV will stay much higher quality than that,
but if people are watching from their PCs, I think you'll see much more
compression going on, given that the hardware processing it has a lot
more horsepower.
