Abstract

Enregistrement et reproduction de signaux vidéo couleurs du procède SECAM. Le dispositif comprend des organes pour séparer un signal vidéo couleur du procédé SECAM en un signal de luminance et un signal porteur de chrominance dont la fréquence est modulée, des organes pour moduler la fréquence d'une onde porteuse avec le signal de luminance, des organes pour diviser la fréquence du signal porteur de chrominance et des organes pour mélanger et multiplexer le signal de luminance modulé en fréquence et le signal porteur de chrominance dont la fréquence a été divisée d'une façon telle que les bandes de fréquence de ces deux signaux ne se recouvrent pas et pour enregistrer le signal obtenu sur un support d'enregistrement ainsi que pour reproduire ce signal enregistré. Suppression du phénomène dit d'inversion de couleurs.
