Abstract

Des décodeurs autorisés (60) sont dotés de clés de réception (66) qui permettent de récupérer les données transmises, dont le code d'identification d'information (65) correspond à une clé de réception (66) du décodeur-récepteur, puis de les afficher sur l'écran vidéo. Des techniques de transmission d'information de pavé (72,1) et de transmission micrographique cellulaire permettent de réduire le volume des données transmises pour modifier les données de mise à jour, des cellules (72,1) de caractères étant transmises sous la forme d'un unique multiplet de données et les cellules (72,1) de données de pixel sous la forme d'un ensemble de multiplets de données. Chaque décodeur-récepteur (60) peut comprendre un certain nombre d'écrans vidéo identifiés séparément et de façon distinctive afin de permettre la transmission de données de mise à jour codées et d'autres messages destinés à des écrans vidéo particuliers. Le système comprend le multiplexage de signaux d'information relatif au marché financier et à des émissions de télévision, et la transmission des signaux multiplexés vers les décodeurs-récepteurs aux fins de l'affichage sélectif de différentes combinaisons d'informations.
