A system controller directs a storage device to output a scene description data corresponding to a user request signal. A parsing circuit extracts a URL (Uniform Resource Locator) included in the scene description data, and causes storage devices to output elementary stream and object stream corresponding to the URL. After extracting an object descriptor from the object stream, a generator generates an ID of this object descriptor and supplies it to an encoder. Further, the generator adds the ID to the object descriptor and outputs the ID-added object descriptor to a multiplexer. The multiplexer multiplexes the scene description data including the ID that has been converted into binary format, the object descriptor and the elementary streams into a multiplexed stream for output thereof.

Un système contrôleur commande un dispositif de stockage à produire des données de description de scène correspondant à un signal de demande utilisateur. Un circuit d'analyse extrait une adresse URL (Uniform Resource Locator) incluse dans les données de description de scène, et amène les dispositifs de stockage à produire un train élémentaire et un train d'objet correspondant à l'URL. Après l'extraction d'un descripteur d'objet du train d'objet, un générateur génère un ID de ce descripteur d'objet et le transmet à un codeur. En outre, le générateur ajoute l'ID au descripteur d'objet et transmet le descripteur d'objet à ID ajouté à un multiplexeur. Le multiplexeur multiplexe les données de description de scène, y compris l'ID qui a été converti en format binaire, le descripteur d'objet et les trains élémentaires en un train multiplexé aux fins de sortie.
