Abstract

L'invention concerne un système et un procédé mis en oeuvre dans un dispositif télévisuel interactif pour gérer l'émission de données sur des canaux de télédiffusion et de point à point. Dans un mode de réalisation, le système comprend une station (10) de télédiffusion, plusieurs stations (20) de réception, un canal de télédiffusion par lequel on peut émettre des données de la station de diffusion vers les stations de réception, et plusieurs canaux (13) point à point, chacun situé entre la station de réception correspondante et la station de télédiffusion. Cette dernière surveille la demande d'éléments d'information particuliers et détermine s'il y a lieu de les livrer par le canal de télédiffusion ou par les canaux point à point. Les éléments d'information très demandés sont télédiffusés de façon cyclique sur le canal de télédiffusion, et ceux qui sont moins demandés sont émis sur les canaux point à point.
