Title: Appareil recepteur de television a reconnaissance automatique de norme.
Inventor: BENDAHAN SAMUEL
IPC: H04N5/46
Filed: 1985-12-27
Abstract: L'appareil selon l'inv)ntion est muni d'un syntoniseur 3, 4 à microprocesseur 1, capable de choisir une émission repérée en fréquence. La reconnaissance de norme s'effectue au cours d'une exploration séquentielle de recherche d'émission. Lorsqu'un signal est détecté dans le circuit FI 5 au cours de cette exploration, il peut aussi bien s'agir d'une porteuse vision de télévision que d'une porteuse son. Alors on incrémente d'un seul coup la fréquence d'oscillateur de 5,5 MHZ ; si on retrouve alors une deuxième porteuse c'est que l'ensemble de ces deux porteuses constitue une émission selon la norme B ou G. Sinon on ajoute encore 0,5 MHZ pour se situer à 6 MHZ de la première porteuse trouvée ; si on trouve alors une porteuse, on a une émission en norme I. Sinon on rajoute encore 0,5 MHZ pour tester si on a une émission en norme L. L'information de norme trouvée est alors exploitée avec la fréquence d'oscillateur qui lui est associée, inscrite dans une mémoire 32. (CF DESSIN DANS BOPI)
