Are you serious?
In case you are serious, IR=infrared.
When you point your TVs remote control toward the TV and press a button, it is the IR receiver on the TV which receives the IR signal which is transmitted from the IR LED (Light Emitting Diode), which is the small bulb like part, on the front end of your remote control.
Any device using a IR remote control, must have an IR receiver to gather the siganl being transmitted. The IR siganl is a coded message of instructions for the device.
