Abstract

L'invention concerne un procédé permettant d'exécuter initialement un fichier multimédia intégré dans lequel sont présentées des pièces d'un contenu multimédia unique, par exemple vidéo, audio, images, et texte, en format de fichier unique, et un système de services multimédia intégrés permettant de mettre en oeuvre ledit procédé. Le système de services multimédia comporte un serveur de présentation d'un contenu multimédia intégré (100) pour déterminer un procédé d'exécution initial relatif à un contenu multimédia intégré selon un procédé de création de contenu multimédia, créer et fournir un contenu par inclusion du procédé d'exécution initial dans une structure d'un format de fichier multimédia intégré du contenu; et un terminal utilisateur (200) pour demander et recevoir un contenu multimédia intégré spécifique provenant du serveur prestataire de contenu multimédia intégré, déchiffrer un procédé d'exécution initial relatif au contenu multimédia intégré spécifique, et, ensuite, exécuter le contenu.
