ABSTRACT:
An electronic system providing a video signal to an output terminal intended to be connected to a receiver having one input impedance out of two input impedances, the electronic system including an adaptable amplifier providing the video signal and capable of operating according to one operation configuration out of two operation configurations, each operation configuration being adapted to one of the two input impedances of the receiver; circuitry for detecting characteristic portions of the video signal; and control and measurement circuitry capable of measuring a signal representative of the current provided to the output terminal by the electronic system during each detected characteristic portion, and of having the adaptable amplifier adopt one of the two operation configurations based on the comparison of the representative measured signal with thresholds.
