Abstract
L'invention concerne l'enregistrement de signaux audiofréquences à l'aide d'un magnétoscope classique. Dans l'appareil de l'invention, les signaux stéréophoniques appliqués aux bornes 3L, 3R sont convertis sous forme numérique, et enregistrés temporairement dans une mémoire 8 qui effectue une compression temporelle créant des espaces suffisants pour l'introduction de signaux de synchronisation, au niveau d'un mélangeur 9. Un processus inverse est accompli au moment de la reproduction des signaux enregistrés. Application aux magnétoscopes pour le grand public
