Abstract

L'invention concerne un procédé et un système permettant à un terminal de décodeur d'être connecté à un système de télévision par câble et à localiser automatiquement le canal ou les canaux de contrôle utilisés par l'opérateur du système de câble pour transmettre des données, des instructions ou une programmation à la population des terminaux de décodeur. Le terminal de décodeur commence par une table de fréquences possibles ou une gamme de fréquences, sur laquelle un canal de contrôle peut être transmis par l'opérateur du système de câble. Le terminal de décodeur règle alors de manière successive ces fréquences, jusqu'à ce que au moins un canal de contrôle soit localisé. Ledit terminal peut aussi faire correspondre un identificateur de plate-forme dans le terminal avec un identificateur de plate-forme dans le flux de données du canal de contrôle, afin de confirmer que le canal de contrôle est approprié au terminal.
