Abstract

The present invention discloses a method for using digital content. According to this method, a user terminal acquires an authorization file at least including a predetermined processing right from the authorization terminal, the predetermined processing right allowing the user terminal to process the digital content in the predetermined manner, e.g. edit the digital content. When the processing right requested by the user is included in the authorization file that the user terminal acquires, the user can perform the predetermined processing on the digital content. This invention also discloses apparatus for using the digital content. The method and apparatus of the present invention can bring better convenience to the user and protect profits of the content provider as well.

Claims

1. A method for authorizing use of a digital content, comprising:

(a) receiving a request from a user side, wherein the request requests to authorize a processing right to the user side, and the processing right allows the user side to process the digital content in a predetermined manner; and

(b) generating an authorization file containing the processing right based on the request to be sent to the user side, so that the user side can process the digital content in the predetermined manner.

2. The method according to claim 1, further comprising:

transmitting said authorization file to said user side.

3. The method according to claim 1, further comprising:

transmitting said digital content to said user side.

4. The method according to claim 1, further comprising:

verifying whether said request derives from a valid user side.

5. The method according to claim 1, wherein said request further comprises an ID of a user side.

6. The method according to claim 5, wherein said ID of the user side includes one of the following ID:

user ID, device ID and AD ID.

7. The method according to claim 1, wherein said predetermined manner comprises at least one of the flowing processing manners:

transcoding the digital content, editing the digital content or extracting some content from the digital content.

8. A method for requesting to authorize a user side to use a digital content, comprising:

(a) transmitting a request, wherein the request requests to authorize a processing right to the user side, and the processing right allows the user side to process the digital content in a predetermined manner;

(b) receiving an authorization file containing the processing right from the authorization side so that the user side can process the digital content in the predetermined manner.

9. The method according to claim 8, wherein said request further includes an ID of a user side.

10. The method according to claim 9, wherein said ID of the user side includes one of the following ID:

user ID, device ID and AD ID.

11. The method according to claim 8, wherein said predetermined manner comprises at least one of the flowing processing manners:

transcoding the digital content, editing the digital content or extracting some content from the digital content.

12. A method for processing a digital content in a user side, the method comprising:

(a) receiving a request, wherein the request requests to process the digital content in a predetermined manner;

(b) verifying whether the user side is authorized to process the digital content in the predetermined manner; and

(c) processing the digital content in the predetermined manner to acquire a processed digital content when the user side is authorized to process the digital content in the predetermined manner.

13. The method according to claim 12, wherein said step (b) comprising:

(i) acquiring an authorization file corresponding to the digital content;

(ii) checking whether a processing right is included in the authorization file, the processing right authorizing the user side to process the digital content in the predetermined manner.

14. The method according to claim 13, wherein said predetermined manner comprises one of the flowing processing manners:

transcoding the digital content, editing the digital content or extracting some content from the digital content.

15. The method according to claim 13, further comprising:

associating related processing information with said processed digital content.

16. The method according to claim 15, wherein said processing information includes at least one of the following information:

said authorization file information, processing manner, processing time, condition of the digital content before processing, or ID of the user side.

17. A method for operating a processed digital content at a user side, the method comprising:

(a) receiving a request, wherein the request requests to operate the processed digital content;

(b) verifying whether the processed digital content is obtained according to a process in an authorized manner; and

(c) acquiring the processed digital content for the user side to operate when the processed digital content is obtained according the process in the authorized manner.

18. Apparatus for authorizing use of a digital content, comprising:

authorization request receiving means for receiving a request from a user side, wherein the request requests to authorize a processing right to the user side, and the processing right allows the user side to process the digital content in a predetermined manner; and

,

generating means for generating an authorization file containing the processing right basing on the request to be sent to the user side, so that the user side can process the digital content in a predetermined manner.

19. The apparatus according to claim 18, further comprising transmitting means for transmitting said authorization file to said user side.

20. The apparatus according to claim 19, wherein said transmitting means is also used for transmitting said digital content to said user side.
