Abstract

Dispositif et procédé pour utiliser le spectre de transition d'un équipement émetteur-récepteur T.V. en découpant des signaux large bande porteurs de données en sous-canaux multiples. Ce système permet d'insérer les canaux de données dans un programme de transmission sans occuper les canaux vidéo. Le dispositif et le procédé servent en particulier à transmettre des sous-canaux de 2MHz à des fréquences de bande de transition vers au moins un client dans un système de communication à deux voies, à réseau asymétrique.
