Abstract
(EN)
An apparatus (100) for recording a file (102) having a related media data container (104) and a metadata container (106), the apparatus a receiver (108) for receiving first data packets (110) comprising packetized first media data samples based on a first clock, and for receiving second data packets (112) comprising second media data samples based on a second clock different from the first clock, wherein the second media data samples are associated to the first media data samples, and for receiving first control packets (114) including information for indicating a relationship of the first clock to a reference clock and for receiving second control packets (115) including information for indicating a relationship of the second clock to the reference clock, and a recorder (116) for storing the received first and second data packets (110; 112) and at least a portion of the received first and second control packets (114; 115) in the media data container (104), and for storing associated metadata (124; 128) in the metadata container (106), the associated metadata comprising timing information of the received first and second data packets and the received first and second control packets and location information indicating a location of the stored first and second data packets and the stored first and second control packets in the media data container.

L'invention concerne un appareil (100) pour enregistrer un fichier (102) muni d'un conteneur de données multimédias apparentées (104) et d'un conteneur de métadonnées (106). L'appareil comporte un récepteur (108) permettant de recevoir des premiers paquets de données (110) comprenant des premiers échantillons de données multimédias mis en paquets sur la base d'une première horloge; des seconds paquets de données (112) comprenant des seconds échantillons de données multimédias sur la base d'une seconde horloge différente de la première horloge, les seconds échantillons de données multimédias étant associés aux premiers échantillons de données multimédias; et des premiers paquets de commande (114) comprenant des informations pour indiquer une relation de la première horloge par rapport à une horloge de référence; des seconds paquets de commande (115) comprenant des informations pour indiquer une relation de la seconde horloge par rapport à l'horloge de référence. L'appareil comporte également un enregistreur (116) pour stocker les premiers et seconds paquets de données reçus (110; 112) et au moins une partie des premiers et seconds paquets de commande reçus (114; 115) dans le conteneur de données multimédia (104) et pour stocker des métadonnées associées (124; 128) dans le conteneur de métadonnées (106), les métadonnées associées comprenant des informations de temps des premiers et seconds paquets de données reçus et des premiers et seconds paquets de commande reçus et des informations de position indiquant une position des premiers et seconds paquets de données stockés et des premiers et seconds paquets de commande stockés dans le conteneur de données multimédias.
