Abstract

L'INVENTION SE RAPPORTE AUX DISPOSITIFS DE DECODAGE DES COULEURS, DANS LE SYSTEME DE TELEVISION EN COULEURS SECAM. LES TEINTES EXACTES S'OBTIENNENT PAR REGLAGE DES DEUX DEMODULATEURS SUR LES FREQUENCES DE REPOS F ET F, TRANSMISES EN DEBUT DE CHAQUE LIGNE, FREQUENCES QUI PEUVENT ETRE PERTURBEES SOIT A L'EMISSION, SOIT A LA RECEPTION. L'INVENTION PREVOIT D'UTILISER L'INTERVALLE DE TEMPS CORRESPONDANT A L'IMPULSION DE SYNCHRONISATION LIGNE POUR ENVOYER AU DEMODULATEUR UNE OU PLUSIEURS FREQUENCES, STABLES ET PRECISES, GENEREES DANS LE TELEVISEUR, QUI SERVIRONT DE REFERENCE POUR L'ASSERVISSEMENT AUTOMATIQUE DU NIVEAU DE SORTIE DU DEMODULATEUR. APPLICATION DANS LES RECEPTEURS DE TELEVISION EN COULEURS SELON LE SYSTEME SECAM.
