Abstract

Device for the simultaneous generation of a plurality of television information signals, characterized in that it comprises means capable of generating, during the scanning of at least one image of an object on which the television signals must contain information and in that this image is produced by an optical system of limited definition on a photo-sensitive screen of a pickup tube, a carrier wave in the output circuit of the pickup tube on which a signal referring to the image is modulated, being such the frequencies of the carrier wave and the limitation of definition that, with the use of electric filters, a sufficiently interference-free separation is possible between the frequency band of the modulated carrier wave and at least the frequency band of a sideband of the same and the frequency bands occupied by modulated carrier waves that are generated occupied by on modulated carriers that are generated in a similar way, or by unmodulated signals on a carrier wave.
