The VL58 enables you to transmit Audio/Video signals from your VCR, Satellite receiver, Cable box, DVD-player, DVD-recorder, Satellite receiver, set top box, PC etc. to a (second) TV without running wires. The transmitter sends an Audio/Video signal from 2 different sources to the receiver via 5.8GHz radio frequency signals. The receiver converts the radio signal back into an A/V signal. The receiver also converts the infrared signals sent by the remote control of the A/V source into radio frequency signals. The transmitter will then reconvert these signals into infrared signals in order to control the connected A/V devices
