Abstract

An apparatus for moving contents includes an input unit for inputting the contents and a control unit for controlling the movement of the contents between storage media by analyzing a copy control code of the contents. The method for moving contents includes the steps of analyzing a copy control code of the contents when a user desires to move the contents from a first storage medium to a second storage medium and storing the contents in the second storage medium by converting the copy control code of the contents according to the result of analysis, thereby providing improved convenience to the user as long as copyrights are not infringed by storing the stored contents in the second storage medium.

Claims

1. A method of managing content, comprising the steps of:

(a) judging whether a control information is a copy control information or moving control information, wherein the control information is associated with a protection of content, and the moving control information indicating whether a moving of content is permitted is distinguished from the copy control information indicating whether a copy of content is permitted or not; and

(b) controlling a protection of content in response to the step (a) such that the content can be copied if the control information is copy control information and the copy control information indicates that a copy of the content is permitted, while the content can be moved if the control information is moving control information and the moving control information indicates that the moving of content is permitted.

2. The method of claim 1, wherein the step (b) controls the protection of content such that the content can not be copied if the control information is copy control information and the copy control information indicates that a copy of the content is not permitted, and the content can not be moved if the control information is moving control information and the moving control information indicates that the moving of content is not permitted.

3. The method of claim 1, further comprising:

(c) deleting the content stored in a storage medium after the moving of content is performed, if the control information is moving control information and the moving control information indicates that the moving of content is permitted.

4. The method of claim 1, further comprising:

(c) performing an operation for not using the content stored in a storage medium after the moving of content is performed, if the control information is moving control information and the moving control information indicates that the moving of content is permitted.

5. The method of claim 1, wherein the moving control information is included in a header of data format, the content comprising at least one data format.

6. The method of claim 1, wherein the step (b) comprises

(b1) performing an authentication with other entity to move the content to other entity if the moving control information indicates that the moving of content is permitted;

and

(b2) determining whether to move the content as a result of step (b1), wherein the content can be moved only when the authentication is performed successfully.

7. The method of claim 6, wherein the authentication is performed using a particular key value.

8. The method of claim 1, wherein the step (b) comprises

(b1) judging whether the content can be stored in other entity if the moving of content is permitted;

and

(b2) determining whether to move the content to the other entity as a result of the step (b1).

9. The method of claim 1, wherein the step (b) comprises

(b1) identifying whether or not the other entity is connected;

and

(b2) determining whether to move the content to the other entity as a result of the step (b1).

10. The method of claim 9, wherein the step (b2) comprises

(b2-1) performing an authentication with other entity if other entity is connected as a result of step (b1);

and

(b2-2) moving the content when the authentication is performed successfully.

11. The method of claim 10, wherein the step (b2-2) comprises

(b2-2-1) judging whether the content can be stored in other entity if the authentication is performed successfully;

and

(b2-2-2) determining whether to move the content to the other entity as a result of the step (b2-2-1).

12. The method of claim 9, wherein the other entity is connected through IEEE1394 or Universal Serial Bus.

13. The method of claim 1, wherein the content is read from first storage medium to move the content to other entity if the moving control information indicates that the moving of content is permitted, wherein an entity including first storage medium is a digital TV receiver, Personal Recorder, Personal computer, Disc apparatus, or Digital Home System.

14. The method of claim 13, wherein other entity is a digital TV or a recording device.

15. The method of claim 1, further comprising:

(c) updating the copy control information to reflect that the copy of content is performed, if the control information is copy control information and the copy control information indicates that the copy of content is permitted.

16. A method of managing content, comprising the steps of:

(a) judging whether a control information is a copy control information or moving control information, wherein the control information is associated with a protection of content, and the moving control information indicating whether a moving of content is permitted is different from the copy control information indicating whether a copy of content is permitted or not; and

(b) controlling a protection of content in response to the step (a) such that the content can be copied if the control information is copy control information and the copy control information indicates that a copy of the content is permitted, while the content can be moved if the control information is moving control information and the moving control information indicates that the moving of content is permitted,

wherein the copy control information is updated to reflect the status if the copy of content is performed, while an operation for not using the content stored in the storage medium is performed after the moving of content is performed, if the control information is moving control information and the moving control information indicates that the moving of content is permitted.

17. An apparatus for managing content, comprising:

a storage unit to store content; and

a controller judging whether a control information is a copy control information or moving control information, wherein the control information is associated with a protection of content stored in the storage unit, and the moving control information indicating whether a moving of content is permitted is distinguished from the copy control information indicating whether a copy of content is permitted or not, and controlling a protection of content in response to the judgment such that the content can be copied to other entity if the control information is copy control information and the copy control information indicates that a copy of the content is permitted, while the content can be moved to other entity if the control information is moving control information and the moving control information indicates that the moving of content is permitted.

18. The apparatus of claim 17, further comprising:

an interface unit to interface with other entity.

19. The apparatus of claim 18, wherein the interface unit is interfaced through IEEE1394 or Universal Serial Bus.

20. The apparatus of claim 18, further comprising:

a receiving unit to receive the content from an external source.

21. The apparatus of claim 20, wherein the external source is broadcasting station, broadcasting satellite, or cable.

22. The apparatus of claim 17, wherein the apparatus is a digital TV receiver, Personal Recorder, Personal computer, Disc apparatus, or Digital Home System.

23. The apparatus of claim 17, wherein other entity is a digital TV or a recording device.
