Definitely not bluetooth, but SONY (and others now I think) do a wireless TV where the only thing you connect to the TV is the power cable. The rest of the unit can be hidden away somewhere in the room and it's that box that you connect your HDMI sources to.
Of course if you hide the box away somewhere, it makes it difficult to use the remote on your SKY+ box etc. (as it would be hidden also). The TV remote uses bluetooth I think (definitely not infra red), so maybe that's what he was thinking of?
