Abstract
The present invention relates to a preamplifier including inputs for receiving input video signals representative of an image to be displayed on a screen, inputs for receiving logic signals representative of information to be displayed in superimposition on the screen, and outputs for supplying output video signals generated based on the input signals or the logic signals. An input receives a control signal to select which signals are used to generate the output video signals. In a first display mode, the signals used are the input signals, and in a second display mode, the signals used are the logic signals. Decoders and controllers allow monitoring of the state of the logic signals which select, in the second display mode, the input video signals to generate the output video signals.
