Abstract

L'invention concerne l'enregistrement et la reproduction de signaux vidéo. Le correcteur de base de temps 25 d'un magnétoscope pour télévision en couleur est associé à un déphaseur variable 40 qui est commandé par un comparateur de phase 41. Le comparateur de phase 41 compare la phase de la salve de chrominance du signal vidéo composite reproduit et la phase du signal de référence de porteuse qui est engendré à partir des signaux de synchronisation horizontale du signal vidéo reproduit. Application aux magnétoscopes pour télévision en couleur.
