Abstract

Comme dans le système de diffusion de données de la demande de brevet principal, la station émettrice diffuse, sous forme de paquets, des données provenant de plusieurs voies, les paquets étant multiplexés dans le temps. La présente invention permet d'utiliser le même système de diffusion quel que soit le standard de télévision utilisé avec un minimum de modifications sur les récepteurs de télévision. On fait varier la fréquence des éléments binaires en fonction de la largeur de bande de signal de télévision correspondant au standard utilisé. Le système est compatible avec les systèmes de télévision.
