Patent

CA 2326728

A method and system is provided to avoid the duplicate storage and transfer of multimedia data in a playback device, thereby increasing system bandwidth and available playback memory. A multimedia composition describes an edited piece of audio and video multimedia data. The composition is created and transferred to a playback device. The composition is examined to determine whether the multimedia data referred to in the composition is already stored in the playback device. If the data is stored in the playback device, or in transit to the playback device, it is not transferred to the playback device.

L'invention concerne un procédé et un système permettant d'éviter un stockage et transfert doubles de données multimédia, dans un dispositif de reproduction, et d'augmenter ainsi la largeur de bande du système et la mémoire de reproduction disponible. Une composition multimédia décrit un ensemble édité de données multimédia audio et vidéo. Cette composition est créée et transférée dans un dispositif de reproduction, puis elle est examinée afin qu'il soit déterminé si les données multimédia contenues dans la composition sont déjà stockées dans le dispositif de reproduction, et si tel est le cas, ou si ces données sont en transit vers le dispositif de reproduction, elles ne sont pas transférées dans celui-ci.
