Abstract

Control arrangement for audio or video apparatus for controlling, for example, colour saturation, brightness, contrast, volume or tone and comprising, provided on an IC, a control circuit 4 which is connected to a connection pin 5 via a control input 4. Outside the IC a control signal source 6 is also connected to this pin. Depending on the choice, such a control signal source produces either an analogue control signal or a digital control signal. To make the applicability of the IC independent of the control signal source opted for, a detection circuit 20 which produces an indication signal which is representative of the form (analogue or digital) of the control signal is connected to the pin. This indication signal controls a switching arrangement 21 the input of which is connected to the said pin and which has first and second outputs. The first output 23 is connected directly and the second output 24 via an interface circuit 25 to the control input of the control circuit. The interface circuit may be a D to A converter.
