Abstract
L'INVENTION CONCERNE L'ENREGISTREMENT DE SIGNAUX DE TELEVISION. LE DISPOSITIF DE L'INVENTION RECOIT SUR UNE BORNE D'ENTREE 1 UN CODE DE TEMPS QUI EST ENREGISTRE EN ASSOCIATION AVEC UN SIGNAL VIDEO, ET IL FOURNIT SUR UNE BORNE DE SORTIE 18 UN SIGNAL QUI INDIQUE SI LA FREQUENCE D'IMAGE DU SIGNAL VIDEO ENREGISTRE EST DE 25 OU DE 30 IMAGES PAR SECONDE. CETTE DETECTION DE FREQUENCE EST BASEE SUR LE FAIT QUE LES NUMEROS D'IMAGE 25 A 29 EXISTENT DANS UN CAS, MAIS N'EXISTENT PAS DANS L'AUTRE. APPLICATION AUX MAGNETOSCOPES BI-STANDARD.
