ABSTRACT:
A fuel station communication system used to transmit audio and video information to customers at fuel pumps. The fuel station communication system includes a transmitter located in a station store and a receiver having a communication unit located at a fuel pump. A wire pair connects the transmitter and receiver together for transmitting audio and video signals from the transmitter to the receiver. To provide for simultaneous transmission of the audio and video signals over the wire pair, the transmitter includes a modulator and signal summer. The modulator modulates the audio signal above the video signal, and the signal summer adds the modulated audio signal and the video signal together to form a combined, audio-video signal. A differential line driver and differential line receiver are connected to provide transmission of the audio-video signal from the transmitter to the receiver. The receiver includes a demodulator for converting the audio-video signal to separate audio and video signals for input into a communication unit located at the fuel pump. To electrically isolate the transmitter and receiver, optical couplers are disposed in the transmitter and receiver and separate power supplies are provided for portions of the transmitter and receiver.
