Abstract

A method and apparatus for moving contents are discussed. According to an embodiment, the method includes determining whether or not a content is to be moved from a first device to a second device based on copy and movement control information, the copy and movement control information indicating whether or not the content is to be moved; performing an authentication to authenticate the first and second devices with each other; and moving the content from the first device to the second device based on the determination result and the authentication result.

Claims

1. A method for moving contents, the method being performed by a device including a receiving unit, a user interface, an analyzing unit, an interface and a control unit, the method comprising:

receiving, via the receiving unit, a content;

storing the content in a storage;

receiving, via the user interface, a request for moving the content;

judging, via the analyzing unit, whether or not the content is permitted to be moved to an external storage based on a moving control information, the moving control information being different from a copy control information indicating whether the copy of the content is permitted;

determining, via the analyzing unit, whether a communication with the external storage through an interfacing port is possible; and

controlling, via the control unit, a moving operation of the content to the external storage such that the content is moved to the external storage through the interfacing port, when the judging step determined the content is permitted to be moved and the determining step determines the communication is possible.

2. The method of claim 1, wherein the moving control information is included in a header of a packet of the content.

3. The method of claim 1, wherein the determining step comprises:

determining whether or not an authentication operation with the external storage is required; and

authenticating the external storage if the authentication operation is determined to be required.

4. The method of claim 3, wherein the moving operation comprises:

moving the content to the external storage if the authentication operation is successfully performed.

5. The method of claim 3, wherein the moving operation comprises:

moving the content to the external storage without the authentication operation if the authentication operation is determined not to be required.

6. The method of claim 3, wherein the authenticating step performs the authentication using at least one key value.

7. A device for moving contents, the device comprising:

a receiving unit configured to receive data;

a storage configured to store data;

a user interface configured to receive a request from a user;

an interfacing port configured to communicate with an external storage; and

a microprocessor configured to;

receive, via the receiving unit, a content,

store the content in the storage,

receive, via the user interface, a request for moving the content,

judge whether or not the content is permitted to be moved to the external storage based on a moving control information, the moving control information being different from a copy control information indicating whether the copy of the content is permitted,

determine whether a communication with the external storage through the interfacing port is possible, and

control a moving operation of the content to the external storage such that the content is moved to the external storage through the interfacing port, when the judging step determined the content is permitted to be moved and the determining step determines the communication is possible.

8. The device of claim 7, wherein the moving control information is included in a header of a packet of the content.

9. The device of claim 8, wherein the microprocessor is further configured to determine whether or not an authentication operation with the external storage is required, and to authenticate the external storage if the authentication operation is determined to be required.

10. The device of claim 9, wherein the microprocessor is further configured to move the content to the external storage if the authenticating operation is successfully performed.

11. The device of claim 9, wherein the microprocessor is further configured to move the content to the external storage without the authentication operation if the authentication operation is determined not to be required.

12. The device of claim 9, wherein the microprocessor is further configured to perform the authentication operation using at least one key value.
