Abstract

A piece of content and an associated original metadata are received by a device. The original metadata may have been corrupted during delivery to the device or may be outdated. The device enables modifying the original metadata. The device comprises an identifier to determine identification data for a piece of content. The identification data may be a fingerprint generated from content. The identification data is used to access a record in a database associated with the piece of content. A processing unit of the device determines a new metadata from the accessed record. The device modifies the original metadata from the new metadata.

Claims

1. A device for altering an original set of metadata associated with a received piece of content, the device comprising:

identifying means for determining identification data identifying the piece of content;

processing means for determining, based on the identification data, a new set of metadata from a database of records associated with respective pieces of content; and

,

means for altering the original set of metadata from the new set of metadata.

2. The device of claim 1, wherein the altering means replaces the original set of metadata with the new set of metadata

3. The device of claim 1, wherein the new set of metadata is further determined based on a profile of a user of the device.

4. The device of claim 1, wherein the original and new sets of metadata are in a structured format.

5. The device of claim 1, wherein the original set of metadata comprises at least one blank field and the altering means fills up the blank field from the new set of metadata.

6. The device of claim 1, wherein the original and new sets of metadata are encoded using a markup language format.

7. The device of claim 1, wherein the original and new sets of metadata are encoded using the MPEG-7 standard.

8. The device of claim 1, wherein the identification data is one of a characteristic pattern, a hash pattern or a fingerprint.

9. The device of claim 1, wherein the original set of metadata is corrupted.

10. The device of claim 1, wherein the original set of metadata is timely outdated.

11. The device of claim 1, wherein the new set of metadata is determined based on an application, for which the piece of content is intended.

12. The device of claim 1, wherein the processing means accesses a record associated with the piece of content using the identification data and wherein the processing means generates the new set of metadata based on information stored in the record.

13. The device of claim 1, wherein the processing means accesses a record associated with the piece of content using the identification data and wherein the processing means retrieves the new set of metadata from a record associated with the piece of content.

14. A circuit arrangement for altering an original set of metadata associated with a received piece of content, the circuit comprising:

an identifying arrangement for determining identification data identifying the piece of content;

a processing arrangement for determining, based on the identification data, a new set of metadata from a database of records associated with respective pieces of content;

an arrangement for altering the original set of metadata from the new set of metadata.

15. A software application including instructions for enabling altering a set of metadata associated with a piece of content, the method comprising:

determining an identification data identifying the piece of content;

determining, on the basis of the identification data, a new set of metadata from database of records associated with respective pieces of content;

altering the original set of metadata from the new set of metadata.
