Title
(EN) A CONTROLLER FOR PROVIDING TIMING SIGNALS FOR VIDEO DATA
(FR) CONTROLEUR FOURNISSANT DES SIGNAUX DE SYNCHRONISATION POUR DES DONNEES VIDEO
Abstract
(EN)
A controller for synchronising video signals for display on a TV screen comprising: a horizontal input storage means for receiving a horizontal synchronising signal of a first sequence for computer generated image data; a vertical input storage means for receiving a vertical synchronising signal of a second sequence for computer generated image data; a first processor means for generating horizontal synchronising signals of a third sequence and a vertical synchronising signal of a fourth sequence; and a second processing means for combining the horizontal synchronising signal of the first sequence and the horizontal synchronising of the third sequence to generate a horizontal synchronising signal of a fifth sequence and for combining the vertical synchronising signal of the second sequence with the vertical synchronising signal of the fourth sequence to generate a vertical synchronising signal of a sixth sequence; wherein the horizontal synchronising signal of the fifth sequence and the vertical synchronising signal of the sixth sequence generated by the second processor means are arranged to provide timing sequences for images data generated by a computer whereby the image data can be displayed on a TV screen.

Contrôleur de synchronisation de signaux vidéo pilotant l'affichage sur un écran TV, comprenant: un moyen de stockage d'entrée horizontale recevant un signal de synchronisation horizontale d'une première séquence de données d'image générées par ordinateur; un moyen de stockage d'entrée verticale recevant un signal de synchronisation verticale d'une deuxième séquence de données d'image générées par ordinateur; un premier processeur générant des signaux de synchronisation horizontale d'une troisième séquence et des signaux de synchronisation verticale d'une quatrième séquence; un deuxième processeur combinant les signaux de synchronisation horizontale de la première séquence et les signaux de synchronisation horizontale de la troisième séquence pour produire des signaux de synchronisation horizontale d'une cinquième séquence et combinant les signaux de synchronisation verticale de la deuxième séquence et les signaux de synchronisation verticale de la quatrième séquence pour produire des signaux de synchronisation horizontale d'une sixième séquence. Les signaux de synchronisation horizontale de la cinquième séquence et les signaux de synchronisation verticale de la sixième séquence générés par le deuxième processeur fournissent des séquences de synchronisation pour les données d'images générées par ordinateur, en vue de leur affichage sur un écran TV.
