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.
