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 the content can be moved to an external entity based on a moving control information, the moving control information being different from a copy control information indicating whether the copy of content is permitted;

(b) determining whether an authentication with the external entity is needed in order to move the content to the external entity, if the content can be moved as a result of step (a); and

(c) controlling the moving operation to the external entity such that the content can be moved to the external entity without the authentication if the authentication is not needed as a result of step (b), while the content can be moved to the external entity only when the authentication is successful if the authentication is needed as a result of step (b).

2. The method of claim 1, wherein the step (b) determines whether the authentication is needed, if the external entity is connected.

3. The method of claim 2, wherein the external entity is connected through IEEE1394 or Universal Serial Bus.

4. The method of claim 1, wherein the step (c) comprises

(c1) checking whether the external entity can store the content when moving the content;

and

(c2) controlling the moving operation based on the step (c1).

5. The method of claim 4, wherein the step (c2) controls the moving operation such that the content can not be moved to the external entity if the external entity can not store the content, while the content can be moved to the external entity if the external entity can not store the content.

6. The method of claim 1, wherein the step (c) controls the moving operation such that the content can be moved to the external entity when the content can be stored in a storage medium of the external entity.

7. The method of claim 1, wherein the authentication is performed using a particular key value.

8. The method of claim 1, further comprising:

deleting the content stored in a storage medium if the content is moved to the external entity.

9. The method of claim 1, further comprising:

performing an operation for not using the content stored in a storage medium after the moving of content is performed.

10. The method of claim 1, wherein the content comprises at least one packet, wherein the moving control information is included in a header of packet.

11. A method for managing content, comprising the steps of:

determining whether digital content can be moved to another entity based on a moving control information if a command for moving the digital content to another entity is received, the moving control information being distinguished from a copy control information indicating whether the copy of content is permitted;

performing an authentication with the other entity using a key value if the content can be moved; and

controlling whether to move the content to the other entity based on a result of performing step.

12. The method of claim 11, wherein the controlling step controls the moving operation such that the content can be moved to the other entity if the authentication is performed successfully as a result of performing step, while the moving operation such that the content can not be moved to the other entity if the authentication is not performed successfully as a result of performing step.

13. The method of claim 12, wherein the key value is each particular key value.

14. The method of claim 12, wherein the controlling step controls the moving operation such that the content can be moved to the other entity if the authentication is performed successfully as a result of performing step and the other entity can store the content.

15. The method of claim 12, further comprising:

performing an operation for not using the content stored in a storage medium after the moving of content is performed.

16. The method of claim 12, wherein the authentication is performed when the other entity can be communicated through an interface.

17. The method of claim 16, wherein the interface is IEEE1394 or Universal Serial Bus.

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

(a) judging whether the content can be moved to an external entity based on a moving control information, the moving control information being different from a copy control information indicating whether the copy of content is permitted;

(b) determining whether a communication is possible with the external entity through an interface, if the content can be moved as a result of step (a); and

(c) controlling the moving operation to the external entity such that the content can be moved to the external entity if the communication is possible as a result of step (b), while the content can not be moved to the external entity if the communication is not possible.

19. The method of claim 18, wherein the interface is IEEE1394 or Universal Serial Bus.

20. The method of claim 18, wherein the step (c) comprises

(c1) performing an authentication with the external entity if the communication is possible;

and

(c2) controlling the moving operation to the external entity such that the content can be moved to the external entity when the authentication is performed successful.

21. The method of claim 20, wherein the authentication is performed using a particular key value.

22. The method of claim 18, further comprising:

(d) performing an operation for not using the content stored in a storage medium after the moving of content is performed.

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

(a) judging whether the content can be moved to an external entity based on a moving control information, the moving control information being different from a copy control information indicating whether the copy of content is permitted;

(b) determining whether to perform an authentication with the external entity in order to move the content to the external entity, if the content can be moved as a result of step (a); and

(c) controlling the moving operation to the external entity such that the content can be moved to the external entity without the authentication if the authentication is not performed as a result of step (b), while the content can be moved to the external entity only when the authentication is successful if the authentication is performed as a result of step (b).

24. The method of claim 23, wherein the step (b) determines whether to perform the authentication depending upon whether the external entity is connected.

25. The method of claim 24, wherein the external entity is connected through IEEE1394 or Universal Serial Bus.

26. An apparatus for managing content, comprising:

a storage unit storing the content; and

a controller judging whether the stored content can be moved to an external entity based on a moving control information, the moving control information being different from a copy control information indicating whether the copy of content is permitted, determining whether an authentication with the external entity is needed in order to move the content to the external entity, if the content can be moved as a result of the judgment, and controlling the moving operation to the external entity such that the content can be moved to the external entity without the authentication if the authentication is not needed as a result of determination, while the content can be moved to the external entity only when the authentication is successful if the authentication is needed as a result of determination.

27. The apparatus of claim 26, further comprising:
