[opendtv] Re: Execs see challenges bringing Net video to TV

Then I guess I'd need somewhat better than a 40 mbps line. These won't be unusual. The point is that if everybody in my neighborhood had that speed we could ALL do all of them at the same time and it wouldn't take petabits/picosecond, just broadband.
Of course I'm expecting if that sort of multicasting is available at all it will only be available thru ISP's (cable&phone cos) as some sort of premium service where either the broadcaster or user has somehow prearranged it. Only very popular sources like the network may have the economy of scale to cost justify it. The folks that do will still be some sort of 'broadcasters'. I'd even imagine something will be arranged for national multicast with provisions for local content and ad insertion.
Of course that makes it sort of like cable is already doing or moving toward with IPTV. And if you made those stations available on free wifi nodes for ad supported TV (at the broadcasters request) you could call it the new lifeline basic mobile tier.

OTOH, if it was real time and everybody watched it the same time in 8 mbps AVC then they would only have to make multicasting work. Five major networks could be pushed for a total of only 40 mbps to the whole neighborhood. 

Other stations would still have to be pull and limited distribution.

Of course nobody really seems to want to make multicasting work.

Hmm, let's see. An HD program gobbles up, let's say 16 Mbps. 100 viewers want to watch the same program, but the start times are staggered by just a few minutes, so that each viewer gets his/her own unicast stream. That's roughly 1.6 Gigabits of traffic to serve 100 viewers. I don't think that even the Verizon FIOS backbone would survive that.
Nope. TiVo, or this article's NetFlix cache box is still safe. The only way that Verizon FIOS works is with multicasting, which is the IP equivalent of OTA broadcasting.

If the networks make all of their shows available online, say 30 minutes
after the show was aired, and if the ISPs' core nets can handle the
demand without too many glitches, pretty soon it makes one wonder why
the networks need to depend on broadcasters and MVPDs. All they need is
ISPs.
