That seems like a good solution to people wanting to play on multiple tvs and having the consol based in the one place.
Everything lives downstairs in my house
Sky box is under the tv, PC, ps3 & ps4, nas & router are behind it.
The PC ps3/4 and sky box all go to a 4 in 2 out 2 Chanel hdmi splitter. 1 goes to my tv and the other runs 30m to my projector upstairs, followed by a 30m toslink fiber optic cable for the surround sound (which the splitter strips from hdmi and sends independantly)
Also got a magic eye set up to switch between everything from upstairs, so it can be done just now, and for the same ball park figure of £100 that the Sony box costs, except you can add to it.
