Hard to really say what it does. I know that the software was created in-house specifically. An article said it can show you "Any player, in any game, at any time". Also read that it's mostly used for post-match briefing, telling the players in one-one meetings where they went wrong and how they can improve.
Honestly, it seems like a cinema and that's about it, but there must be more to it than that. You don't work in a million pound industry and get a hard on over a big tv.
Edit: I guess it depends what's on tv...
