Abstract

La présente invention concerne l'adjonction de signaux sonores pendant les paliers de suppression horizontale d'un signal de télévision couleur. De façon à rendre le signal composite son-vidéo compatible avec les récepteurs de télévision domestiques actuels, les signaux sonores sont transmis en partie avant le signal de synchronisation couleur, et en partie après. Application à la télévision.
