Title (EN) METHOD TO BIND THE USE OF A TELEVISION RECEIVER TO A PARTICULAR NETWORK
(FR) PROCÉDÉ POUR LIER L'UTILISATION D'UN RÉCEPTEUR DE TÉLÉVISION À UN RÉSEAU PARTICULIER
Abstract:
(EN) A method to bind the use of a digital audio / video service data receiver to a network on which at least one services provider broadcasts access controlled and free digital audio / video services streams,, the method is characterized by steps of: receiving by the receiver a periodic signal transmitted by a conditional access system server via the network, said periodic signal being processed by a run time software embedded in the receiver to check legitimacy of the network, displaying services available on the network only if said run time software recognizes the periodic signal as indicating network legitimacy, checking operability of the run time software and if necessary taking actions to enforce limitation of using the receiver on the network checked as legitimate. The invention further discloses a receiver bound to a specific network configured to perform the method.
(FR) L'invention concerne un procédé pour lier l'utilisation d'un récepteur de données de service audio/vidéo numérique à un réseau sur lequel au moins un fournisseur de services diffuse des flux de services vidéo/audio numérique gratuits et à accès contrôlé. Le procédé se caractérise par les étapes consistant à : recevoir par le récepteur un signal périodique transmis par un serveur de système d'accès conditionnel par l'intermédiaire du réseau, ledit signal périodique étant traité par un logiciel exécutable intégré dans le récepteur pour vérifier la légitimité du réseau ; afficher les services disponibles sur le réseau uniquement si le logiciel exécutable reconnaît le signal périodique comme indiquant la légitimité du réseau ; vérifier l'opérabilité du logiciel exécutable et, si nécessaire, entreprendre les actions pour appliquer une limitation d'utilisation du récepteur sur le réseau vérifié comme étant légitime. L'invention concerne en outre un récepteur lié à un réseau spécifique configuré pour mettre en œuvre le procédé.
