  • the more capacity of a memory the more media content files may be stored in the terminal and as a consequence the number of transmissions between the server and the terminal may be kept at a lower level with decreased costs for transmission.
  • Another advantage of a higher capacity of memory is the possibility to compensate for possible insufficient radio coverage.
  • the terminal has a small memory or no memory at all, ordering from a central or intermediate server must be done more frequently, and as a consequence the enduser prices depends more on the cost of transmission, but on the other hand the cost for memory decreases. Given that media content is supposed to be provided to endusers at LUC conditions, e.g.
  • a virtual jukebox principle at constant enduser price for media content, the cost for transmission, and the cost for memory respectively, are thereby compared and may vary within the frame of what the enduser is prepared to pay for having access to his or her favourite content at any time where-ever it is.
  • the time parameter, max_tim in combination with the memory capacity parameter, max_cap constitutes a base for determination of the enduser price parameter.
  • Another requirement related to the memory capacity is that selected and stored media content may be erased and replaced by media content that has been ordered later, due to lack of memory space, according to the principle first in first out. As a consequence time parameter is measured and registrated for the "old" media content which is subject to deletion.
  • - Control function Compares activities registered in the server against activities registrated in the terminal. This function also serves as a correction function, e.g. if a download or rendering activity is not properly performed, the statistics function is not updated.

Abstract

La présente invention concerne un système de distribution et de restitution de contenus de média comprenant un serveur (C1, C2, ) pour la distribution de contenus, et au moins un terminal (A1, A2, ) pour la commande, la réception, le stockage et la restitution d'un contenu. Le serveur comprend un émetteur (1), un récepteur (3), un processeur (5), une mémoire (7), un programme d'ordinateur (9) et une unité mobile ou un adaptateur de support électro-mécanique (10). Ce système de distribution est conçu pour recevoir une commande de contenu sonore ou visuel d'un terminal, pour commander et recevoir ledit contenu au moyen d'un fichier de données tiré d'une base de données (D1, D2, ) qui comprend un contenu, et de transmettre ledit contenu au terminal via un fichier de données. Le terminal comprend un émetteur (21), un récepteur (23), un processeur (25), une mémoire (27), un programme d'ordinateur (29), un dispositif (31, 32, 33, 34) pour la restitution du contenu et un dispositif (34, 36) commandant à l'émetteur de soumettre une commande audit serveur. Ledit récepteur est conçu pour recevoir le contenu sélectionné dudit serveur au moyen du fichier de données, cependant que le dispositif de restitution est conçu pour restituer ledit contenu commandé et reçu. Le terminal comprend en particulier un dispositif (29) de suppression automatique dudit contenu commandé et reçu au moyen d'un fichier de données immédiatememt après expiration d'un laps de temps limité.
