In an information distribution system (100), a control channel modem (114) provides independent communications channels for bi-directional message traffic between a service provider (102) and a set-top terminal (118) located within a subscriber's home. The modem (114) transmits messages, control information and status information between the service provider (102) and the subscriber's set-top terminal (118) using an independent channel (downstream path) that is different from the channel (upstream path) used for sending requested information such as movies from the service provider (102) to the subscriber's home (108).

Ce modem (114) permet de transmettre des messages, des informations de commande et d'état entre le fournisseur (102) de services et le terminal (118) de décodeur de l'abonné, au moyen d'un canal indépendant (chemin aval) qui est distinct du canal (chemin amont) utilisé pour l'envoi d'informations requises, tels des films, du fournisseur (102) de services au domicile (108) de l'abonné.
