A cable television system ( ) includes a transmitter ( ) for generating a digital optical signal ( ) and a receiver ( ) for receiving said digital optical signal and converting it to an analog signal. The transmitter ( ) includes a processor ( ) for processing inputs and generating a gain/loss parameter which is applied via a gain/loss amplifier ( ) to an incoming analog signal ( ). The modified digital signal received by the digital optical receiver ( ) decodes the applied gain/loss parameter at a converter ( ) and applies the information to the output analog signal via a gain/loss amplifier ( ).
