  • the mtd file is a backward-link information file in which backward-link information of a content which each asset is referring to is defined. That is, the mtd file is a file in which information of an MPV file linked to an asset referencing (or linking) corresponding content is defined, and can be described by the XML as shown in FIG. 5.
  • An mtd file shown in FIG. 5 defines information of a plurality of MPV files linked to an asset referencing the content DCIM/101ABCDE/SAMS0001 in the MPV Link shown in FIG. 1. As seen in FIG. 5, it is impossible to recognize the extension of the asset linked to the MPV file on the basis of the MPV file information defined in the mtd file. Since the MPV file information defined in the mtd file represents LastURL of each MPV file, the MPV file information includes a file name and mpv:id information of each MPV file. FIG. 5 shows an mtd file in which four LastURL items are defined as MPV file information.
  • the metadata synchronization apparatus 410 receives information for an edited asset from the metadata editing unit 402, the metadata synchronization apparatus 410 searches for an mtd file of the edited asset in the mtd file unit 403, detects an asset referencing the same content as the edited asset on the basis of items defined in the mtd file, and synchronizes metadata of the detected asset with metadata of the edited asset.
  • the asset detected based on the items defined in the mtd file references the same content as the edited asset, however, it is referenced (or linked) by a different file.
  • the metadata synchronization apparatus 410 includes an mtd file search unit 411, an asset detector 412, and a synchronization processor 413.
  • the mtd file search unit 411 receives information for an edited asset from the metadata edit unit 402, the mtd file search unit 411 searches for an mtd file of the edited asset in the mtd file unit 403 using the information for the edited asset.
  • the mtd file is an mtd file with the same file name as the edited asset and the extension of 'mtd'. That is, the mtd file search unit 411 searches for a corresponding mtd file using LastURL of the edited asset.
  • LastURL of the received edited asset is / DCIM/101ABCDE/SAMS0001
  • the mtd file search unit 411 searches for a file / DCIM/lOlABCDE/SAMSOOOl.mtd as a corresponding mtd file.
  • the searched mtd file is transmitted to the asset detector 412.
  • the asset detector 412 detects an asset referencing the same content as the edited asset in the received mtd file. That is, the asset detector 412 determines whether a different item exists other than items corresponding to the edited asset among items (e.g. LastURL in FIG. 5) defined in the received mtd file.
  • items e.g. LastURL in FIG. 5
  • the asset detector 412 determines whether or not the different item is an item parsed for synchronizing metadata. The determination can be carried out with reference to separate management information for items parsed for synchronizing metadata or can be carried out using various methods to distinguish parsed items from non-parsed items. If the different item is a non-parsed item, the asset detector 412 obtains LastURL of an asset linked to the different item from the MPV file unit 401. Then, the asset detector 410 determines whether the asset linked to the different item is an asset referencing the same content as the edited asset with reference to the LastURL obtained from the MPV file unit 401. If the asset linked to the different item does not reference the same content as the edited asset, the asset detector 412 completes detecting an asset referencing the same content as the edited asset.
  • the asset detector 412 provides the asset to the synchronization processor 413. If a plurality of assets are detected, the asset detector 412 can transmit the respective detected assets one by one to the synchronization processor 413.
  • the synchronization processor 413 provides information for the detected asset transmitted from the asset detector 412 to the user interface 420. If the synchronization processor 413 receives a synchronization request from the user interface 420, the synchronization processor 413 synchronizes metadata of the detected asset with the metadata of the edited asset provided from the metadata editing unit 402. Accordingly, in the MPV file unit 401, the detected asset has the same metadata as the edited asset.
  • the synchronization processor 413 After the synchronization processor 413 receives the detected assets from the asset detector 412 and synchronizes the assets, the synchronization processor 413 can request for the asset detector 413 to transmit following detected assets. If no following detected asset is provided from the asset detector 412 to the synchronization processor 413, the synchronization processor 413 completes synchronizing the metadata of the edited asset with that of the detected asset.
  • the asset detector 412 and the synchronization processor 413 operate for each item defined in the mtd file.
  • the user interface 420 transmits the editing request to the metadata editing unit 402. Also, if information indicating whether the user wants synchronization for the detected asset is received from the metadata synchronization apparatus 410, the user interface 420 informs the user of the information. If a synchronization request is received from the user, the user interface 420 provides the synchronization request to the synchronization processor 413 of the metadata synchronization unit 410.
  • FIG. 6 is a flowchart illustrating a metadata synchronization method according to an embodiment of the present invention.
  • step 601 if metadata is edited as described above with reference to the metadata editing unit 402 of FIG. 4 (step 601), it is determined whether an mtd file of an asset with the edited metadata exists in the mtd file unit 403 (step 602).
  • step 603 it is determined whether an item not subjected to parsing for synchronizing metadata exists among the remaining items except for items corresponding to the edited asset in items defined in the mtd file (step 603). That is, it is determined whether there is an item not subjected to parsing for determining whether or not an asset linked to the remaining items is an asset referencing the same content as the edited asset.
  • an asset linked to the non-parsed item is parsed (step 604). That is, referring to FIG. 5, LastURL of the linked asset is detected from the MPV file unit 401 on the basis of LastURL of the non-parsed item. If a plurality of non-parsed items exist, assets linked to the non-parsed items can be parsed in an order of items defined in the mtd file.
  • step 605 it is determined whether the parsed asset references the same content as the edited asset (step 605). If LastURL of a parsed asset is equal to LastURL of the edited asset, it is determined that the parsed asset references the same content as the edited asset. However, if the LastURL of the parsed asset is different from the LastURL of the edited asset, it is determined that the parsed asset references different content from the edited asset.
  • step 603 If the parsed asset does not reference the same content as the edited asset, the process is returned to step 603. On the contrary, if the parsed asset references the same content as the edited asset, a fact that a different asset referencing the same content is detected, is reported to the user (step 606).
  • step 602 If in step 602, no mtd file corresponding to the edited asset exists in the mtd file unit 403, or if in step 603, no non-parsed item exists in the mtd file, synchronizing metadata of assets referencing the same content is complete.

Abstract

L'invention concerne une méthode et un appareil pour synchroniser des métadonnées d'ensembles différents référençant les mêmes contenus, au moyen d'un fichier d'informations à corrélation en amont d'un ensemble, lorsque les métadonnées de cet ensemble sont éditées. La méthode de l'invention consiste à: éditer une métadonnées d'un premier ensemble; détecter un second ensemble référençant le même contenu que le premier ensemble, au moyen d'un fichier d'informations à corrélation en amont présentant un contenu se référant au premier ensemble; et synchroniser les métadonnées du second ensemble avec les métadonnées éditées du premier ensemble. Par conséquent, il est possible de synchroniser facilement les métadonnées d'ensembles dans une pluralité de fichiers MPV référençant le même contenu.
