Abstract

Dispositif pour l'enregistrement et la reproduction de signaux d'information sur un support d'enregistrement Ce dispositif comprend des organes pour séparer un signal vidéo couleur en un signal de luminance et un signal porteur de chrominance, pour transformer la fréquence de ce dernier en une bande de fréquence inférieure, pour moduler la fréquence d'ondes porteuses présentant des signaux audio et vidéo, et des organes pour reproduire le signal obtenu sous la forme d'un signal principal d'information sur une piste d'un support d'enregistrement. L'invention concerne également un dispositif pour assurer la reproduction des signaux ainsi enregistrés. Application à l'enregistrement et la reproduction de signaux vidéo et de signaux audio en réduisant notamment la distorsion de battement desdits signaux.
