ABSTRACT:
An apparatus for detecting the properly terminated connection between video components transmitting a video signal from one video component to the other. The video and/or data signal is input to a resistance element. A first comparison input device is connected to the input side of the resistance element and a second comparison input device is connected to the output side of the resistance element. A comparison unit is provided for comparing the voltages from the first comparison input device and the second comparison input device to determine whether there is a voltage drop across the resistance element thereby determining whether the video component is properly terminated. A data processing element connected to the output of the comparison unit receives data from the comparison unit which is detected across the resistance element.
