Abstract

L'invention a pour objet un procédé pour coder un signal vidéo couleur, en particulier pour enregistrer un tel signal sur un support d'enregistrement magnétique, dans lequel l'information de chrominance (chromaticité) modulée à une première fréquence porteuse est transformée en une information de chrominance biséquentielle modulée en amplitude à une seconde fréquence porteuse après séparation de l'information de luminance dudit signal vidéo couleur. Selon l'invention, on sépare ladite information de chrominance modulée de ladite information de luminance, on démodule ledit signal de chrominance, on réalise une modulation double équilobrée du signal de chrominance non modulé, on module en fréquence ledit signal de luminance à une troisième fréquence porteuse et on combine additivement le signal de chrominance biséquentiel modulé en amplitude.
