Hey there!

Perhaps I am using the wrong terminology? I'm talking about the signals that most every remote sends out? That is IR, right?

The IR eye thing that they have seems very simple, it's just a small box that is hooked to a little unit that has four IR wires coming off of it. When the box detects an IR signal, it sends the IR signal to all four of the IR wires attached to it. That way, only the box has to be exposed to the remote control, and all of the components can see the IR signal because of the four IR wires to it.
