Abstract

Méthode et appareil pour permettre à un système de télévision par câble d'émettre des informations à partir d'un module de gestion de système (102), de déterminer si les informations sont destinées à un appareil monté sur téléviseur conçu pour recevoir des informations hors bande ou des informations dans la bande passante, et d'envoyer les informations au circuit approprié. Une partie des informations doivent être reformatées; c'est le rôle d'un traducteur de format (701). Les informations dans la bande passante peuvent être transmises sur un ou plusieurs flux de données. Certains types d'informations sont transmises sur un ou plusieurs flux de données, selon leur type et selon les caractéristiques des flux de données. De plus, par souci d'efficacité, des informations semblables destinées à plusieurs adresses sont regroupées dans un système de gestion de bases de données (702) de sorte que l'on peut envoyer les informations à plusieurs adresses en même temps. Des brouilleurs (104, 209) sont prévus, qui sont capables d'insérer des données dans des canaux non brouillés.
