Abstract

Cette invention se rapporte à un procédé qui permet d'envoyer des données à une station client via un serveur de commande central (102) pour fournir des services de données à la demande et qui consiste à cet effet: à recevoir un fichier de données, à spécifier un intervalle de temps, à effectuer le parçage de ce fichier de données en plusieurs blocs de données sur la base de l'intervalle de temps, pour que chaque bloc de données soit affichable pendant un intervalle de temps, à déterminer un nombre requis d'intervalles de temps pour envoyer le fichier de données, à attribuer à chaque intervalle de temps au moins un premier bloc de données et éventuellement un ou plusieurs blocs de données additionnelles, pour que, en partant de n'importe lequel des intervalles de temps, (i) le fichier de données puisse être affiché par accès au premier bloc de données; (ii) lors d'un intervalle de temps suivant, un bloc de données suivant, consécutif à un bloc de données préalablement affiché, soit disponible pour affichage; et (iii) à répéter les étapes (ii) jusqu'à ce que tous les blocs de données pour le fichier de données ont été affichés, et à envoyer les blocs de données sur la base de l'étape d'attribution.
