It's a digital signal, you source the power from TV's scattered around.
I tested the game for a week in November last year.
I've tested this game, as recent as last week. I know the storyline and what happens and I can tell you, the graphics are nothing I haven't seen on a PC game 2-3 years ago. Obviously its a prototype, so they could get better. But The graphics are very crisp and no horrible jaggies, which has put me off console gaming ever since I've had the option to get rid of htem on my PC.
It's a digital signal you get from TV's. Trust me.
