Definitions

  • a computer program product for use in formatting data, as described in the opening paragraph, is provided, the computer program comprising program code means for causing a processor to perform the method as described in relation to the third aspect of the invention.
  • the measures according to the invention have the effect that the reading device can retrieve data without knowledge about their exact positions in the user area, as defined for example by the used file system.
  • the device is arranged as a stand alone unit, for example a video playback/recording device for consumer use.
  • the control unit 20, or an additional host control unit included in the device is arranged to be controlled directly by the user.
  • the device includes application data processing, for example audio and/or video processing circuits.
  • the information presented to the write unit 29 may comprise analog audio and/or video, or digital uncompressed audio/video signals; in this case the write unit 29 may comprise compression means for these signals.
  • the read processing unit 30 may comprise suitable audio and/or video decoding units.
  • the file retrieval unit 31 For each data file packet found in data blocks, the file retrieval unit 31 stores corresponding part of the data file in the memory unit 32. The retrieval of the data file is completed upon storing in the memory unit 32 all parts of the data file indicated by the total data file packet sequence number. Thus, instead of checking for a particular file system, the file retrieval unit 31 simply reads sequentially data blocks from the record carrier, starting at the beginning of the user area, for example right after the lead-in area on an optical disc.
  • control unit 20 includes a firmware update unit 33 for upgrading a software for controlling operations of the device with upgrade data comprised in the data file stored in the memory unit 32.
  • the file retrieval unit 31 can be adapted for retrieving plurality of data files, wherein each data file is identified by file identification data, which file identification data is comprised in each data file packet.
  • the file retrieval unit 31 allocates separate memory parts of the memory unit 32 for different data files and retrieves parts of those data files in dependence of file identification data; each data file is identified by a unique file name.
  • a computer pseudo-code in Figure 7 describes another example of a method performed by the file retrieval unit 31 to read and re-assemble the data file.
  • a checksum of 4 bytes is assumed, therefore the payload is reduced to 464 bytes as compared with 468 bytes in Figure 6.

Abstract

La présente invention concerne un dispositif de lecture pour lire des données à partir d'une porteuse d'enregistrement amovible (11). Le dispositif comprend un moyen de lecture (21, 22, 25) pour lire les données enregistrées sur le vecteur d'enregistrement et un moyen de commande (20) pour commander la lecture. De plus, le dispositif comprend un moyen de récupération de fichiers (31). La récupération des données est indépendante du système de fichiers sous lequel les données ont été enregistrées ; elle est indépendante des données du système de fichiers sur le vecteur d'enregistrement. De plus, pour la récupération, le vecteur d'enregistrement n'a pas besoin d'être monté sous la commande de tout système de fichier.
