Abstract

L'invention porte sur un émetteur-récepteur bidirectionnel destiné à combiner de façon continue des informations Internet avec des informations vidéo afin de créer une interface d'affichage interactif que pourra visualiser un utilisateur. Cet émetteur-récepteur comprend un syntoniseur intrabande destiné à recevoir un signal de diffusion numérique et générer à partir de celui-ci un flux de données. Le syntoniseur intrabande est couplé à un décodeur audio vidéo qui décode le flux de données pour obtenir un signal vidéo. L'émetteur-récepteur comprend également un modem câble destiné à établir une communication bidirectionnelle à l'aide de protocoles Internet. Le fonctionnement du syntoniseur intrabande, du décodeur audio vidéo et du modem câble est géré et coordonné par une unité centrale. L'unité centrale est un composant possédant un processeur numérique couplé à une mémoire. La mémoire est destinée à stocker un code lisible par un ordinateur qui, lorsqu'il est exécuté par le processeur, fait effectuer par l'émetteur-récepteur les fonctions requises pour créer l'affichage interactif destiné à l'utilisateur. Lors de la création de l'affichage, l'interface d'affichage obtenue comprend des informations vidéo provenant du signal vidéo et une page web provenant du modem câble. Le signal d'interface d'affichage, que pourra visualiser l'utilisateur, est couplé à un moniteur. L'émetteur-récepteur reconnaît l'entrée utilisateur lorsqu'il y a interaction de l'utilisateur avec des éléments de l'interface d'affichage. L'entrée utilisateur est transmise en amont au moyen du modem câble.
