Abstract

GENERATEUR DE CONTOUR POUR FORMER UNE BORDURE ENCADRANT UN CARACTERE SUR UN ECRAN DE TELEVISION. LE SIGNAL FOURNI PAR UN GENERATEUR DE CARACTERE EST CONVERTI SOUS FORME NUMERIQUE ET RETARDE D'UN NOMBRE ENTIER DE LIGNES PAR DES MOYENS DE MEMORISATION NUMERIQUE 10. LE SIGNAL RETARDE EST COMPARE26 AU SIGNAL NON RETARDE POUR FOURNIR UNE PREMIERE INFORMATION DE BORDURE. LE SIGNAL RETARDE I EST A NOUVEAU RETARDE 30 D'UNE FRACTION DE LIGNE ET CE NOUVEAU SIGNAL RETARDE EST COMPARE 36 A I POUR FOURNIR UNE SECONDE INFORMATION DE BORDURE QUI EST COMBINEE 50 A LA PREMIERE POUR ENGENDRER UN SIGNAL DE BORDURE. L'INVENTION EST UTILISABLE POUR METTRE EN RELIEF DES CARACTERES APPARAISSANT SUR UN ECRAN DE TELEVISION.
