The security modules used in pay television and in other applications are intended to develop and thus to be replaced. In order to promote the replacement of a previous generation by a new one, the method according to the invention consists in sending by a control centre in the data stream a replacement prompt command including the minimal characteristics of the security module of the new generation, establishing the characteristics of the security module being used, and comparing with the minimal characteristics defined by the received command, and according to the results of this comparison, starting a prompt cycle by sending a warning indication on the screen.

Les modules de sécurité utilisés aussi bien dans la télévision ô péage que dans d'autres applications utilisant un moyen quelconque de visualisation, sont appelés ô évoluer et donc être remplacés. Afin de favoriser ce remplacement d'une génération antérieure par celui d'une nouvelle génération, la méthode selon l'invention consiste à envoyer par un centre de contrôle dans le flux de données, une commande d'incitation de remplacement incluant les caractéristiques minimales du module de sécurité de nouvelle génération, établir les caractéristiques du module de sécurité en cours d'utilisation et comparer avec les caractéristiques minimales définies dans la commande reçue, et selon le résultat de la comparaison, initier un cycle incitatif par l'envoi d'un avertissement sur l'organe de visualisation.
