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.

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. -- Alex Thurlow Technical Director Blastro Networks _______________________________________________ NANOG mailing list [email protected] http://mailman.nanog.org/mailman/listinfo/nanog _______________________________________________ NANOG mailing list [email protected] http://mailman.nanog.org/mailman/listinfo/nanog
