Abstract
L'invention concerne un appareil d'affichage visuel de données. Des caractères sont affichés par modulation d'une trame du type télévision sur un tube à rayons cathodiques. L'espace normalement uniforme entre les lignes de balayage de la trame est modifié pour augmenter ou diminuer l'intervalle entre des rangées de caractères. Des signaux de modulation, de synchronisation et de commande sont extraits d'un signal composite d'entrée et les signaux de commande sont utilisés pour commander un circuit de modifiation de balayage. Application à l'affichage des données.
