A cable television system (400) includes a transmitter (200) for generating
a digital optical signal (204) and a receiver (300) for receiving said
digital optical signal and converting it to an analog signal. The
transmitter (200) includes a processor (238) for processing inputs and
generating a gain/loss parameter which is applied via a gain/loss
amplifier (250) to an incoming analog signal (232). The modified digital
signal received by the digital optical receiver (300) decodes the applied
gain/loss parameter at a converter (325) and applies the information to
the output analog signal via a gain/loss amplifier (330).
