ABSTRACT:
A video circuit including a video amplifier adapted to generate an amplified output video signal from an input video signal; a short detection circuit adapted to generate a first signal indicative of whether there is a short present at an output of the video amplifier; and a load detection circuit adapted to generate a second signal indicative of whether there is a load coupled to the output of the video amplifier. The video circuit may further include an input signal detection circuit adapted to generate a third signal indicative of whether an input video signal is present. The third signal generated by the input signal detection circuit may be used to enable the outputting of the first and second signals in order to prevent the false indication of faults at the output of the video amplifier in the absence of an input video signal.
