Abstract

a. Synthétiseur vidéo pour un système d'affichage numérique vidéo. b. Synthétiseur caractérisé en ce qu'il comprend un réseau d'addition donnant une séquence d'un ensemble de niveaux de tension différents, niveaux qui sont choisis à partir de trois ou plusieurs niveaux pour désigner des valeurs de luminance différentes destinées à être affichées, le réseau d'addition ayant un ensemble de conducteurs d'entrée différents, un dispositif de stockage avec un ensemble de conducteurs de sortie couplés à des conducteurs d'entrée du réseau d'addition, le dispositif de stockage enregistrant les divers codes unitaires pour activer les différentes combinaisons des conducteurs d'entrée ainsi qu'un moyen couplé au dispositif de stockage pour transmettre un code binaire à ce dispositif, code qui désigne un code unitaire pour choisir la luminance particulière que l'on veut afficher.at. Video synthesizer for a digital video display system. b. Synthesizer characterized in that it comprises an addition network giving a sequence of a set of different voltage levels, levels which are chosen from three or more levels to designate different luminance values intended to be displayed, the addition network having a set of different input conductors, a storage device with a set of output conductors coupled to input conductors of the addition network, the storage device storing the various unit codes to activate them different combinations of the input conductors as well as a means coupled to the storage device for transmitting a binary code to this device, which code designates a unit code for choosing the particular luminance that is to be displayed.
