  • the public data network may further include wired networks and wireless networks such as cable, DSL, and satellite as well as dial-up.
  • Source 20 is a source of multimedia files 12 which, in an exemplary embodiment, are commercial multimedia files 12.
  • source 20 may further comprise an online resource such as a file server connected to data network 100 or physical media such as optical or magnetic media or the like.

  • Encoded multimedia file 12 is provided to network operation center 40 such as over data network 100 or via a physical storage medium such as electronic, magnetic, or optical media, or the like, or combinations thereof. Once provided, encoded multimedia file 12 is stored at network operation center 40 at step 220.
  • Source 20 also provides, at step 230, network operation center 40 with a predetermined set of scheduling parameters relevant to encoded multimedia file 12, such as delivery or scheduling parameters. Using these parameters, a predetermined set of transmission parameters for encoded multimedia file 12 may then determined at step 240, e.g. locations of receivers 30, a schedule timetable, or the like, or combinations thereof. [0017] Encoded multimedia file 12 may then be transmitted, at step 250, to one predetermined receiver 30 or to a plurality of receivers 30 over the data network 100 according to the predetermined set of scheduling and/or transmission parameters.

Abstract

La présente invention concerne un système et un procédé de fourniture d'un fichier multimédia (12) par un fournisseur à un récepteur (30). Le système comprend une source (20) contenant un fichier multimédia (12) à fournir, et un récepteur (30) destiné à recevoir le fichier multimédia (12), lesquels sont en communication fonctionnelle avec le réseau de données (100), ainsi qu'un centre d'exploitation de réseau (40) qui est communication fonctionnelle avec le réseau de données (100) et placé logiquement entre la source (20) et le récepteur (30). Le récepteur (30) comprend en outre un logiciel de manipulation de fichiers (32, 34) qui permet la manipulation de fichiers multimédia (12) codés. Un fichier multimédia (12) est codé puis fourni au centre d'exploitation de réseau (40) qui stocke le fichier multimédia (12) codé en même temps qu'un ensemble prédéterminé de paramètres de programmation concernant le fichier multimédia (12) codé. A l'aide de ces paramètres de programmation est déterminé un ensemble prédéterminé de paramètres de transmission pour le fichier multimédia (12) codé qui peut alors être transmis à un récepteur (30) prédéterminé par l'intermédiaire du réseau tiers, selon l'ensemble prédéterminé de paramètres de transmission. Au niveau du récepteur (30), le logiciel de manipulation de fichiers codés (32, 34) peut être mis en oeuvre selon l'ensemble prédéterminé de paramètres de programmation.
