Abstract
A remotely-controlled cable equalization system includes a control unit containing a non-volatile memory, a plurality of remote video display devices, each of which includes an adjustable cable equalization circuit, and an interface for connecting the control unit to each of the plurality of remote video display devices. Each of the plurality of remote video display devices includes a receiver for receiving a 12-bit digital code, from the control unit, through the interface. A 12-bit register is connected to the receiver and a 12-bit digital-to-analog converter is then connected to the 12-bit register, for receiving a 12-bit digital code from the 12-bit register and for converting the digital signal to an analog signal. The adjustable cable equalization circuit in each of the plurality of remote video display devices receives the analog signal from the 12-bit digital-to-analog converter and provides the necessary cable equalization for each of the plurality of remote video display devices based on the received analog signal.
