Abstract

L'INVENTION CONCERNE L'ENREGISTREMENT MAGNETIQUE DES SIGNAUX VIDEO. UN DISPOSITIF DE CORRECTION D'ERREUR DE BASE DE TEMPS COMPREND NOTAMMENT UNE MEMOIRE 59 DANS LAQUELLE LE SIGNAL VIDEO REPRODUIT PAR UN MAGNETOSCOPE, ET CONVERTI SOUS FORME NUMERIQUE, EST ENREGISTRE AVEC UNE CADENCE D'HORLOGE QUI SUIT LES ERREURS DE BASE DETEMPS INTRODUITES PAR LES OPERATIONS D'ENREGISTREMENT ET DE REPRODUCTION. CE SIGNAL EST ENSUITE LU DANS LA MEMOIRE 59 AVEC UNE CADENCE D'HORLOGE FIXE, ET EN CAS DE PERTE D'INFORMATION, L'ELEMENT D'IMAGE PERDU EST REMPLACE PAR L'ELEMENT D'IMAGE OCCUPANT LA MEME POSITION DANS LA LIGNE IMMEDIATEMENT PRECEDENTE. APPLICATION AUX MAGNETOSCOPES UTILISES EN TELE-DIFFUSION.
