Building the set, and lighting it up, are the easy bits considering the technology that's being deployed there!
Yes, quite. Although I imagine the technology in the studio itself isn't that much different to the norm compared with new IP infrastructure they're working with everywhere else.
I can't remember the deails, I don't think even the studios are 100% SDI, it would be silly not to use format agnostic IP than hardwire yourself into 1.5 or 3 G SDI.
That said there'll be an awful lot of SDI<>IP glue
