Abstract

LA PRESENTE INVENTION CONCERNE EN PARTICULIER UN PROCEDE PERMETTANT DE TRANSMETTRE UNE INFORMATION SON DANS UNE IMAGE DE TELEVISION SANS GENER LA SYNCHRONISATION VIDEO. UN INTERVALLE DE DIX SECONDES D'UNE INFORMATION DE FREQUENCE SON EST ECHANTILLONNE, MIS SOUS FORME NUMERIQUE ET EMMAGASINE DANS UNE MEMOIRE. IL EST ALORS EXTRAIT DE LA MEMOIRE BEAUCOUP PLUS VITE, PAR EXEMPLE QUATRE CENTS FOIS PLUS VITE, CONVERTI EN FORME ANALOGIQUE, COMBINE AVEC DES SIGNAUX DE SYNCHRONISATION DE TELEVISION ET TRANSMIS COMME UNE IMAGE UNIQUE DE TELEVISION. LE SIGNAL EST RECU, CONVERTI DE LA FORME ANALOGIQUE A LA FORME NUMERIQUE, MEMORISE A GRANDE VITESSE ET ENSUITE EXTRAIT A UNE VITESSE DE FREQUENCE SON POUR RECUPERER L'INFORMATION ORIGINELLE DE SON DE DIX SECONDES. APPLICATION A LA TRANSMISSION D'INFORMATIONS ANNEXES SUR UN CANAL DE TELEVISION.
