Abstract

Provided is an image display device. The image display device includes an interface, a memory, a controller, and a display unit. The interface supports communication with an external storage medium, and the memory stores data transmitted through the interface. The controller compares attribute information of data stored in the memory with that of data stored in the external storage medium when the external storage medium is connected through the interface and controls changing of a data name of data stored in the memory or a data name of data stored in the external storage medium depending on whether the attribute information is identical. The display unit displays whether a data name is changed in response to a control signal from the controller.

Claims

1. An image display device comprising:

an interface being configured to connected an external storage medium;

a memory storing data transmitted through the interface;

a controller comparing attribute information of data stored in the memory with that of data stored in the external storage medium when the external storage medium is connected through the interface, and controlling changing of a data name of data stored in the memory or a data name of data stored in the external storage medium depending on whether the attribute information is identical; and

a display unit displaying whether a data name is changed in response to a control signal from the controller.

2. The image display device according to claim 1, wherein the attribute information comprises unique identification generated by the controller.

3. The image display device according to claim 1, wherein the attribute information comprises meta data corresponding to each data.

4. The image display device according to claim 1, wherein the controller updates a data name of the data stored in the memory using a data name of recently modified data when the attribute information is the same as a result of the comparison.

5. The image display device according to claim 1, wherein the controller compares the attribute information and then changes data names of data stored in one of the memory and the external storage medium using recently modified data names.

6. The image display device according to claim 1, wherein the controller stores together the attribute information including at least one of a reproduction time of data, a program title, a capacity, a file format, and channel information when storing the data.

7. The image display device according to claim 1, wherein the controller displays a user selection menu for changing a data name of data when the attribute information of respective data is the same as a result of the comparison.

8. A method for updating data in an image display device, the method comprising:

connecting an external storage medium to the image display device;

comparing attribute information of data stored in a memory inside the image display device with attribute information of data stored in the external storage medium; and

changing a data name of data stored in the memory or a data name of data stored in the external storage medium depending on whether the attribute information is identical.

9. The method according to claim 8, wherein the attribute information comprises unique identification generated according to a generation point and a generation sequence of data.

10. The method according to claim 8, wherein the attribute information comprises meta data corresponding to each data.

11. The method according to claim 8, wherein the operation of changing the data name comprises updating the data name of the data stored in the internal memory using a data name of recently modified data when the attribute information of respective data is the same as a result of the comparison.

12. The method according to claim 8, wherein the operation of changing the data name comprises, after the comparing of the attribute information, changing data names of data stored in one of the internal memory and the external storage medium using recently modified data names.
