RF and IR
The Aurora from Universal Remote Control (www.universalremote.com) can operate every piece of audio and video equipment in a home as well as a Media Center PC. Connected to the PC by cable and programmed on screen, this versatile unit transmits RF and IR signals simultaneously, and the user can even be in the next room.
An IR Emitter
An IR emitter (left) is pasted onto the IR sensor on this DVD/VHS player. The wire traces back to a Home Theater Master RF base station that picks up the RF and converts it to infrared. No matter whether a remote control is RF or IR, the signal generally winds up as IR at the equipment.
