Abstract
(DE)
Es wird eine Signalverarbeitungseinheit für ein digitales TV-System beschrieben, die sich insbesondere auszeichnet durch eine erste Einrichtung (3) zur Beaufschlagung eines Videosignals mit graphischen Bildelementen und Textzeichen, sowie eine zweite Einrichtung (4) zur Bildratenwandlung, wobei der Ausgang der ersten Einrichtung (3) mit dem Eingang der zweiten Einrichtung (4) verbunden ist und der Ausgang der zweiten Einrichtung (4) eine Treiberstufe (6) zum Ansteuern eines Displays beaufschlagt.
(EN)
The invention relates to a signal processing unit for a digital TV system. The inventive unit is especially characterized by a first device (3) provided for admitting a video signal containing graphic picture elements and text characters, and by a second device (4) for converting the image rate. The output of the first device (3) is connected to the input of the second device (4), and the output of the second device (4) actuates a driver stage (6) for driving a display.
(FR)
L'invention concerne une unité de traitement de signaux pour un système de télévision numérique, caractérisée en particulier par une première unité (3) servant à recevoir un signal vidéo comportant des éléments d'image graphiques et des caractères de texte, et par une deuxième unité (4) servant à convertir le taux d'images. La sortie de la première unité (3) est reliée à l'entrée de la deuxième unité (4), et la sortie de la deuxième unité (4) actionne un étage de commande (6) servant à commander un dispositif d'affichage.
