Abstract

A method and apparatus for synchronizing metadata of different assets referencing the same contents, using a backward-link information file of an asset when metadata of the asset is edited, the method including: editing a metadata of a first asset; detecting a second asset referencing the same content as the first asset using a backward-link information file of content which the first asset refers to; and synchronizing metadata of the second asset with the edited metadata of the first asset. Therefore, it is possible to easily synchronize metadata of assets in a plurality of MPV files referencing the same content.

Claims

1. A method for synchronizing metadata, the method comprising:

editing a metadata of a first asset;

detecting a second asset referencing a same content as the first asset using a backward-link information file of content which the first asset refers to; and

synchronizing metadata of the second asset with the edited metadata of the first asset.

2. The method of claim 1, further comprising:

if the second asset is detected, informing a user that the second asset is detected; and

if a synchronization request for the second asset is received from the user, performing the synchronizing the metadata of the second asset with the edited metadata of the first asset.

3. The method of claim 2, wherein if a plurality of non-parsed items exist in the backward-link information file, the detecting, the informing, and the synchronizing are performed for each item.

4. The method of claim 1, wherein, if a plurality of non-parsed items exist in the backward-link information file, the detecting and the synchronizing are performed for each item.

5. A method for synchronizing metadata of assets in a system including an MPV file unit and a backward-link information file unit, the method comprising:

editing metadata of a first asset;

searching for a backward-link information file of a content which the first asset refers to, in the backward-link information file unit;

determining whether a second asset detected from the MPV file unit based on the backward-link information file references a same content as the first asset; and

if the second asset references the same content as the first asset, synchronizing metadata of the second asset with the edited metadata of the first asset.

6. The method of claim 5, further comprising:

if the second asset references the same content as the first asset, reporting detection of the second asset to a user; and

if a synchronization request is received from the user, performing the synchronizing the metadata of the second asset with the edited metadata of the first asset.

7. An apparatus for synchronizing metadata, the apparatus comprising:

an MPV file unit having information for at least one asset;

a metadata editing unit editing metadata of a first asset;

a backward-link information file unit having a backward-link information file of at least one content;

a search unit searching for a backward-link information file of a content which the first asset refers to, in the backward-link information file unit based on information of the first asset provided from the metadata editing unit;

an asset detector detecting a second asset referencing the same content as the first asset using the searched backward-link information file and the information included in the MPV file unit; and

a synchronization processor synchronizing metadata of the second asset with the edited metadata of the first asset.

8. The apparatus of claim 7, wherein the synchronization processor informs a user that the second asset is detected, and synchronizes the edited metadata of the second asset with the edited metadata of the first asset if a synchronization request is received from the user.

9. The apparatus of claim 7, wherein, if the backward-link information file has a plurality of non-parsed items, the asset detector detects an asset referencing the same content as the first asset for each item.

10. A computer-readable medium having embodied thereon a computer program for executing a method for synchronizing metadata,

the method comprising:

editing metadata of a first asset;

detecting a second asset referencing a same content as the first asset using a backward-link information file of a content which the first asset refers to; and

synchronizing metadata of the second asset with the edited metadata of the first asset.
