Abstract

A method and apparatus for moving contents using copy and movement control information are discussed. According to an embodiment, the method includes transmitting, by a first device, a copy of a content using a copying operation to a second device based on copy and movement control information; updating, in the first device, the copy and movement control information based on the copying operation; determining, by the first device, whether or not the content is to be moved based on the copy and movement control information, the copy and movement control information indicating whether or not the content is to be moved; and moving, by the first device, the content to a third device based on the determination result.

Claims

1. A method for controlling contents, comprising:

transmitting, by a first device, a copy of a content using a copying operation to a second device based on copy and movement control information;

updating, in the first device, the copy and movement control information based on the copying operation;

determining, by the first device, whether or not the content is to be moved based on the copy and movement control information, the copy and movement control information indicating whether or not the content is to be moved; and

moving, by the first device, the content to a third device based on the determination result.

2. The method of claim 1, wherein the moving step moves the content from the first device to the third device, if the determining step determines that the content is to be moved.

3. The method of claim 2, wherein the moving step includes deleting the content from the first device.

4. The method of claim 1, wherein the moving step does not move the content from the first device to the third device, if the determining step determines that the content is not to be moved.

5. The method of claim 1, wherein the copy and movement control information is represented by three bits.

6. The method of claim 1, further comprising:

receiving, by the first device, the content along with the copy and movement control information, wherein the copy and movement control information is located at a head field associated with the content.

7. A first device for controlling contents, comprising:

a transmitting unit configured to transmit a copy of a content using a copying operation to a second device based on copy and movement control information;

a control unit configured to update the copy and movement control information based on the copying operation; and

a determination unit configured to determine whether or not the content is to be moved based on the copy and movement control information, the copy and movement control information indicating whether or not the content is to be moved,

wherein the control unit is further configured to move the content to a third device based on the determination result.

8. The first device of claim 7, wherein the control unit moves the content from the first device to the third device, if the determination unit determines that the content is to be moved.

9. The first device of claim 8, wherein the moving of the content from the first device to the third device includes deleting the content from the first device.

10. The first device of claim 7, wherein the control unit does not move the content from the first device to the third device, if the determination unit determines that the content is not to be moved.

11. The first device of claim 7, wherein the copy and movement control information is represented by three bits.

12. The first device of claim 7, further comprising:

a receiving unit configured to receive the content along with the copy and movement control information, wherein the copy and movement control information is located at a head field associated with the content.
