Abstract

An information processing method according to the present invention for editing multimedia content including metadata includes a receiving step and a determining step. In the receiving step, operation information about an editing operation is received. In the determining step, it is determined whether or not the metadata is usable for the edited multimedia content in accordance with the operation information and a property of the metadata in which a change in the reliability of the metadata due to the editing operation is written.

Claims

1. A method for editing multimedia content including metadata, the method comprising:

receiving operation information about an editing operation;

adding the operation information to the metadata;

writing the reliability information to the metadata;

reading the operation information and reliability information from the metadata; and

determining, in accordance with the operation information and the reliability information, whether the metadata is usable for edited multimedia content edited by the editing operation,

wherein, if the metadata is determined to be usable, the metadata is added to the edited multimedia content.

2. A method according to claim 1, wherein the reliability information indicates the reliability of the metadata.

3. A method according to claim 1, wherein the reliability information is based on the operation information.

4. A method according to claim 1, wherein determining whether the metadata is usable includes comparing the reliability information with predetermined reliability information.

5. Computer-executable process steps stored on a computer-readable storage medium, the computer-executable process steps causing a computer to execute the method of claim 1.

6. An electronic device for editing multimedia content including metadata, the electronic device comprising:

a memory, comfigured to store computer-executable instructions; and

a processor for executing the computer-excutable instructions stored in the memory, the computer-executable instructions comprising instructions for;

receiving operation information about an editing operation;

adding the operation information to the metadata;

writing reliability information to the metadata;

reading the operation information and reliability information from the metadata; and

determining, in accordance with the operation information and the reliability information, whether the metadata is usable for edited multimedia content edited by the editing operation,

wherein, if the metadata is determined to be usable, the metadata is added to the edited multimedia content.

7. An electronic device according to claim 6, wherein the reliability information indicates the reliability of the metadata.

8. An electronic device according to claim 6, wherein the reliability information is based on the operation information.

9. An electronic device according to claim 6, wherein determining whether the metadata is usable includes comparing the reliability information with predetermined reliability information.
