Abstract: A video and/or audio decoder provided with a first terminal for supplying an analog audio and/or video signal, including: a first circuit capable of supplying a digital signal which is an image of said analog signal; a digital-to-analog converter capable of receiving as an input said digital signal; an amplifier coupling a second output terminal of the digital-to-analog converter to the first terminal; and a second circuit capable of comparing a signal representative of the voltage or current level on the first terminal with a reference signal, and of deducing therefrom whether the first terminal is connected or not to an analog input terminal of a video signal display and/or audio signal playing device.

Abstract: An analog video signal supply circuit includes a processing circuit that supplies first and second digital video signals. First and second digital-to-analog converters convert digital signals to analog signals. A control circuit controls operation in a first configuration where the first digital video signal is applied to an input of the first digital-to-analog converter and the second digital video signal to an input of the second digital-to-analog converter. The control circuit further controls operation in a second configuration where the first digital video signal is simultaneously applied to the inputs of the first and second digital-to-analog converters.
