You're confusing terms that are independent of what's actually being discussed. If it is Internet based, it's Internet service and prioritized with all other Internet traffic. If it's traffic that does not go over the internet, but instead through another infrastructure (such as a public switched telephone network, or a local multi-cast network for TV service) it gets prioritized however is deemed appropriate. Just because you watch it on your TV doesn't make it separate from Internet service.

No, sorry. The point made was that a lot of communication is being moved using TCP/IP. So they use the same infrastructure.

Right. What if Youtube and Hulu start bundling their services as part of Verizon's TV service and thus enjoy higher QoS than other video startups?

Thats a loophole now.
