Abstract

La présente invention a trait à la technique de communication et peut trouver des applications dans des systèmes de radiodiffusion télévisuelle et de télévision par câble pour la diffusion d'informations sous forme de code numérique. L'objectif recherché est une conception simplifiée et l'abaissement du côut des systèmes de transmission. Pour cela, on transmet dans la partie supérieure de la bande du canal télévisuel, exempte des spectres de porteuses de signaux vidéo et audio de télévision, une quantité paire de porteuses supplémentaires formant une série séquentielle de paires, réparties en fréquence de manière à éviter un mélange de leurs spectres. Chaque paire de porteuses supplémentaires voisiness est modulée par son propre signal numérique par déplacement en fréquence sans rupture de phase, la fréquence de modulation étant supra-acoustique. On choisit comme indice de modulation moins d'une unité et/ou on limite préalablement la bande de spectre des porteuses modulées par déplacement en fréquence dans les parties se trouvant en dehors des paires de ces porteuses.
