Abstract
Dans le système de télétexte, les données transmises comprennent, outre les octets de service classiques (étiquette, drapeau de page, numéro de page, drapeau de rangée, numéro de rangée) des octets de fonction permettant de faire varier le modèle des caractères affichés. Les octets de fonction déterminant les composantes de l'identité d'un modèle de caractères sont précédés d'un octet de signal d'échappement Deux mémoires vives sont associées aux mémoires mortes du générateur de caractères. L'une des mémoires vives sert normalement à emmagasiner les codes de caractères, l'autre à emmagasiner les octets de caractères, l'autre à emmagasiner les octets d'identité des modèles. Les deux mémoires vives sont lues simultanément, l'une sert à extraire la forme du caractère dans une mémoire morte, l'autre à définir la couleur, les dimensions d'affichage, etc. Utilisable dans les dispositifs ou systèmes d'affichage de textes.
