Abstract

L'invention concerne un procédé permettant à un dispositif client de télévision par câble de charger, pendant une séquence de mise en marche, des applications sélectionnées dans une mémoire en provenance d'un dispositif serveur de télévisions par câble couplé au dispositif client. Le dispositif serveur transmet une table de services à tous les dispositifs clients dans le réseau. Les dispositifs clients reçoivent la table de services et stockent la table en mémoire. La table de services contient une liste d'une pluralité d'applications de services individuels disponibles à un abonné utilisant le dispositif client. Le dispositif client détermine alors celle des applications de services individuels dans la table de services qui est dénotée comme étant l'application à charger lors de l'initialisation et tente de télécharger ces fichiers à partir du dispositif serveur. Les applications dénotées comme étant des applications devant être chargées sont demandées par le serveur comme devant être téléchargées entièrement avant qu'un dispositif client ne puisse commencer des opérations normales, mais les applications dénotées comme étant des applications à chargement préféré peuvent être interrompues par une commande effectuée par l'abonné sur le dispositif client demandant au dispositif client de commencer immédiatement les opérations normales.
