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

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.
