Abstract

A mobile terminal and method for managing channel information in a DMB receiver, are discussed. According to an embodiment, the method for managing channel information in a DMB device, includes managing, in the DMB device, channel information of each of different channel types of DMB independently.

Claims

1. A method for managing channel information in a Digital Multimedia Broadcast (DMB) device, the method comprising:

managing, in the DMB device, channel information of each of different channel types of DMB independently.

2. The method according to claim 1, wherein the managing step includes:

storing, in the DMB device, the channel information of each of the different channel types of DMB separately.

3. The method according to claim 2, wherein the managing step further includes:

in response to a user'"'"'s selection of a particular DMB channel type to be provided, displaying channel information of the selected DMB channel type among the stored channel information of different channel types of DMB.

4. The method according to claim 2, further comprising:

generating an integrated channel information integrating the channel information of the different channel types of DMB; and

managing the integrated channel information in the DMB device.

5. The method according to claim 4, wherein changes to the channel information are applied to both the stored integrated channel information and the separately stored channel information.

6. The method according to claim 1, further comprising:

managing the channel information of each of the different channel types of DMB together as an integrated channel information.

7. The method according to claim 1, wherein each channel information includes at least one of the following:

a channel number, a channel name, and a channel provider name for each of corresponding channels.

8. The method according to claim 1, wherein the different channel types of DMB include at least one of an audio broadcast, a video broadcast including video and audio data, and a data broadcast.

9. The method according to claim 8, further comprising:

automatically selecting an audio broadcast type as a desired DMB channel type, if the DMB device is without a display unit.

10. The method according to claim 8, wherein the DMB device is without a display unit, and the method further comprises:

automatically selecting a video broadcast type as a desired DMB channel type, if the DMB device is connected to a display device; and

automatically selecting an audio broadcast type as a desired DMB channel type, if the DMB is not connected to the display device.

11. The method according to claim 8, further comprising:

automatically selecting an audio or data broadcast type as a desired DMB channel type, if the DMB device includes at least two display units and only one of the at least two display units is viewable.

12. The method according to claim 11, wherein the only one viewable display unit is an external display unit.

13. The method according to claim 1, wherein the DMB device includes at least two display units, and the method further comprises:

displaying an Electronic Program Guide (EPG) on one of the at least two display units if two of the at least two display units are viewable.

14. The method according to claim 1, wherein the DMB device is a slide type DMB device having a main display unit and a sub display unit, and the method further comprises:

detecting if the slide type DMB device in an opened state; and

displaying an Electronic Program Guide (EPG) on the sub display unit if the detecting step indicates that the slide type DMB device is in the opened state.

15. The method according to claim 1, wherein in the managing step, the DMB device is a mobile terminal.

16. A method for managing channel information in a Digital Multimedia Broadcast (DMB) device including at least two display units, the method comprising:

displaying a DMB of a certain channel on a first display unit of the at least two display units; and

displaying an Electronic Program Guide (EPG) on a second display unit of the at least two display units if the first and second display units are simultaneously viewable.

17. The method according to claim 16, wherein the displayed EPG pertains to the displayed DMB of the certain channel.

18. The method according to claim 17, wherein the DMB device is a slide type DMB device having a main display unit and a sub display unit, and the method further comprises:

detecting if the slide type DMB device in an opened state, so that the displaying step displays the EPG on the sub display if the detecting step indicates that the slide type DMB device is in the opened state.

19. A Digital Multimedia Broadcast (DMB) terminal for displaying an Electronic Program Guide (EPG), the terminal comprising:

a main display unit;

a sub display unit; and

a controller to display video of a program received through a specific DMB channel on the main display unit and to display EPG information on the sub display unit, when the sub display unit is viewable.

20. The DMB terminal according to claim 19, wherein the sub display unit is either viewable or not viewable depending on a movement of the main display unit.

21. The DMB terminal according to claim 20, wherein the main display unit moves vertically or horizontally.

22. The DMB terminal according to claim 20, further comprising:

a detector to detect the movement of the main display unit so as to determine when the sub display unit is viewable.

23. The DMB terminal according to claim 20, wherein the main display unit is exposed on an external panel of the DMB terminal, whereas the sub display unit is exposed on an inner panel of the DMB terminal.

24. The DMB terminal according to claim 20, wherein the DMB terminal is a cellular phone or a PDA.
