To demonstrate...multicast TV distribution on a home network?

> For small home networks, there is no bandwidth difference between this and streaming solutions like Jellyfin.

Jellyfin and multicast TV distribution are not the same things, though. They're very different.

Some other things that are very different include: The temperature of Lake Superior, my mother's collection of weird ceramic houses that light up, and red herring.

Multicast has ceased to be a cool technology? That's hot.

They do that.

They do that, as well.

All of it? Uniformly?

> Does anyone watch scheduled television anymore except local news and sportsball?

We should not use multicast TV distribution on home networks for local news and sportsball?
