Abstract

L'INVENTION CONCERNE LA RECHERCHE AUTOMATIQUE DE SEQUENCES ENREGISTREES. UN CAPTEUR 20 LIE A LA BOBINE RECEPTRICE DE RUBAN 12 FOURNIT DES IMPULSIONS A UN COMPTEUR 23. UN ENREGISTREMENT PRELIMINAIRE DE MARQUES NUMERIQUES EST EFFECTUE PAR UN CIRCUIT DE CODAGE 24 EN FONCTION DE L'EVOLUTION DU CONTENU DU COMPTEUR 23. A LA LECTURE, UN DECODAGE EST EFFECTUE PAR LE CIRCUIT 25, POUR COMMANDER EN CONSEQUENCE LE COMPTEUR 23. LORS D'UNE RECHERCHE DE SEQUENCES, UNE LOGIQUE 28 COMMANDE EN FONCTION DE L'ADRESSE DESIREE UNE PRESELECTION GROSSIERE EFFECTUEE EN DEFILEMENT RAPIDE A L'AIDE D'UN COMPTEUR D'ESTIME 26 REMPLI INITIALEMENT PAR LE CONTENU DU COMPTEUR 23, ET EST MIS A JOUR ENSUITE A PARTIR DE LA SORTIE DU CAPTEUR 20. ENSUITE, UNE SELECTION FINE EST FAITE EN DEFILEMENT LENT D'APRES LA SORTIE DU CIRCUIT DE DECODAGE ENREGISTREMENT 15. APPLICATION NOTAMMENT AUX ENREGISTREURS-LECTEURS A CASSETTES.
