Abstract
L'invention concerne l'enregistrement et la reproduction de signaux stéréophoniques. Un dispositif d'enregistrement de signaux stéréophoniques sur un magnétoscope 1 comprend en particulier un codeur 8 qui code sous forme numérique les signaux stéréophoniques de la voie gauche et de la voie droite, avec adjonction de bits de parité et de mots de code de correction d'erreur; et un décodeur 12 qui décode les signaux numériques, et les corrige en cas de détection d'erreur. Application à l'enregistrement de signaux stéréophoniques sur un magnétoscope.
