Very simple. The set consists of a transmitter and a receiver. You just need to connect the transmitter to your A/V device (e.g., satellite or DVD player) and then connect the receiver to your second television. Additionally, with the infrared extension, you can continue to operate an A/V device located elsewhere (or in a closed cabinet) with your own remote control as usual. Video and stereo sound are transmitted wirelessly through walls and ceilings. Suitable for all brands of DVD players, satellite receivers, decoders, etc. Enjoy your entire digital TV offering on a second television.
