Who Me Too'd this topic

I've seen an announcement from Fox Sports that they are producing some sports content in 4k (including the superbowl!).

My question is, does that come through the same HD channel or is there a new channel for fox sports 4k?

Is there anyway to tell if I am getting 4k?

And if I wanted to use my fancy high-end TV to do 4k upscaling (which I think involved setting the resolution to 1080p?) would that result in 4k->1k->4k ?
