Abstract

The present invention provides a mobile terminal and method for display of detailed information regarding digital rights management (DRM) contents in an intuitive and direct manner for the user. The detailed information includes information items that are attributes of the DRM contents (such as types, sizes, and created dates) or usage rights in licenses of the DRM contents (rights to play, display, execute, print, and export the DRM contents). Those information items associated with selected DRM contents are displayed using text or icons.

Claims

1. A method for displaying digital rights management (DRM) contents of at least one DRM content stored in a mobile terminal having a display unit, comprising:

displaying on the display unit a content list comprising the at least one stored DRM content; and

displaying on the display unit detailed information and licenses of the at least one stored DRM content of the displayed content list in zones associated therewith.

2. The method of claim 1, wherein the detailed information comprises at least one type of information item selected from the group consisting of at least one attribute of the at least one DRM content and at least one usage right selected from the group consisting of play, display, execute, print, export, and transmit the at least one DRM content through short-range communication.

3. The method of claim 2, wherein the displaying detailed information further comprises one step selected from the group consisting of displaying at least one information item associated with the at least one DRM content in the displayed content list, and displaying at least one information item associated with a selected DRM content of the displayed content list.

4. The method of claim 3, wherein the displaying detailed information further comprises:

displaying a first item of the at least one information item; and

displaying, subsequent to a pre-set time duration after display of the first item, a second item of the information item different from the first information item instead of the first information item.

5. The method of claim 4, wherein the displaying detailed information further comprises displaying a rights value selected from the group consisting of a rights value of the first item using one of an image and text and a rights value of the second item using one of an image and text.

6. The method of claim 3, wherein the displaying detailed information further comprises:

displaying in a zone a first item of the at least one information item; and

displaying in the zone, subsequent to a pre-set time duration after display of the first item, a second item of the at least one information item that is different from the first item in the zone while shifting the first information item and the second information item in a single direction.

7. The method of claim 6, wherein the displaying detailed information further comprises the step of displaying a rights value of the first item using an image or text and, when the second item exists, a rights value of the second item using an image or text.

8. The method of claim 3, wherein the displaying detailed information further comprises:

displaying an icon corresponding to a selected one of the at least one information item; and

displaying a rights value of the selected at least one information item next to the icon using an image or text.

9. The method of claim 3, wherein the displaying detailed information further comprises:

selecting a DRM content in the displayed contents list; and

displaying a bubble text describing at least one information item associated with the selected DRM content.

10. The method of claim 3, wherein the displaying detailed information further comprises:

scanning a range of the mobile terminal;

determining an availability of external resources in the scanned range; and

when at least one available external resource is determined, performing the steps of

determining which available external resource is valid for which displayed DRM content of the content list, and

displaying at least one of a text and an image to represent the at least one determined valid available external resource in zones for corresponding DRM contents.

11. The method of claim 3, wherein the displaying detailed information further comprises:

mapping each of the detailed information items to at least one key value;

receiving a key value from a user;

finding each information item mapped to the received key value; and

displaying each found information item in a zone for a corresponding DRM content of the content list.

12. The method of claim 3, wherein the displaying detailed information further comprises:

displaying an image representing the information item;

finding a rights value corresponding to the information item; and

changing at least one of brightness and saturation of the image representing the information item in accordance with the found rights value.

13. The method of claim 1, further comprising issuing a vibration alert if a found rights value of a DRM content in the content list is less than or equal to a pre-set value, a vibration alert.

14. A mobile terminal for displaying digital rights management (DRM) contents, comprising:

a memory unit for storing at least one DRM content;

a display unit for displaying a content list of the at least one DRM content; and

a control unit for controlling a display operation to display detailed information regarding the displayed at least one DRM content in zones for the at least one DRM content, wherein the detailed information is related to at least one of attributes of the at least one DRM content and licenses of the at least one DRM content.

15. The mobile terminal of claim 14, wherein the detailed information comprises at least one information item selected from the group consisting of attributes of the at least one DRM content of the content list and rights to play, display, execute, print, and export the at least one DRM content.

16. The mobile terminal of claim 15, wherein the control unit controls the display operation to perform one of the steps selected from the list consisting of displaying at least one information item associated with each DRM content in the content list, or displaying at least one information item associated with a selected DRM content of the content list.

17. The mobile terminal of claim 16, wherein the control unit controls the display operation to display the at least one information item in a sliding manner in which the at least one information item being displayed is moved in corresponding zones in a single direction.

18. The mobile terminal of claim 16, wherein the control unit controls the display operation to display a first image representing a selected information item, and to display a second image representing a rights value of the selected information item next to the first image.

19. The mobile terminal of claim 16, wherein the control unit controls the display operation to display a text representing a selected information item, and to display an image representing a rights value of the selected information item.

20. The mobile terminal of claim 16, wherein the control unit controls the display operation to display a bubble text describing at least one information item associated with a selected DRM content of the content list in a zone for the selected DRM content.

21. The mobile terminal of claim 16, wherein the control unit scans a range of the mobile terminal to check an availability of external resources, and controls the display operation to display at least one information item corresponding to the availability of external resources that is valid in connection with the at least one DRM content using at least one of an image and text.

22. The mobile terminal of claim 16, wherein the control unit controls the display operation to display an image representing a selected information item, finds a rights value of the selected information item, and controls the display operation to change at least one of brightness and saturation of the image according to the found rights value.

23. The mobile terminal of claim 16, wherein the control unit checks a rights value of a selected information item, and issues a vibration alert if the rights value is less than or equal to a pre-set value.
