Abstract

L'invention concerne un procédé de demande de ressource comprenant les étapes consistant à : recevoir une demande d'invocation envoyée par un premier système multimédia dans un système multimédia hétérogène, et utilisée pour invoquer une ressource multimédia d'un second système multimédia, le système multimédia hétérogène contenant le premier système multimédia et le second système multimédia ; en réponse à la demande d'invocation, transcoder la ressource multimédia selon un format de transcodage requis par le premier système multimédia ; et envoyer la ressource multimédia transcodée au premier système multimédia. La solution technique de l'invention résout le problème lié, dans l'état de la technique, au fait que toute intercommunication entre des systèmes multimédias hétérogènes est impossible. Grâce à l'invention, une interconversion de ressources multimédias et une signalisation de commande entre une pluralité de systèmes multimédias (hétérogènes) devient possible, ce qui permet d'exécuter une intercommunication entre les systèmes multimédias hétérogènes.
