For example, when the partner terminal appears during the reproduction of the content, the content may be controlled to be displayed on an external display device having a wide screen.

There are various ways in which the mobile terminal 100 reproduces the content using the third display device. For example, DLNA (Digital Living Network Alliance) technology may be used. DLNA technology refers to mutual interoperability technology that enables various contents stored in PC, mobile phone, etc. to be displayed on a display device such as a TV using a network.

Generally, storage devices such as PCs and servers can store various media. The various media can be transmitted to other devices, but a media stream of the media can be provided to the display device so that the media stream can be displayed on the display device. In DLNA technology, a device that plays a role of storing media is called a DMS (Digital Media Server). A device acting as a DMS is a data storage device with a large storage capacity.

Also, in DLNA technology, a device that displays media stored in the DMS is a DMR (Digital Media Renderer), and a device having a control function for displaying media stored in the DMS on the DMR is a DMC (Digital Media Controller) All. A device serving as a DMR is a device having a display function such as a TV or a monitor because it can display the corresponding media.

In the present invention, the mobile terminal 100 serves as a DMC, and the external display device can serve as a DMR.

The content can be provided to the external display device through the wireless communication unit 110 of the mobile terminal 100 when the mobile terminal 100 plays the role of the DMS. Further, under the control of the mobile terminal 100, when the third content storage server acts as a DMS, it can control to provide content from the third content storage server to the external display device.

As described above, when the partner terminal appears in the vicinity of the mobile terminal 100, the mobile terminal 100 can control the external display device to reproduce the content.

In FIG. 9A, the mobile terminal 100 can notify the fact that the counterpart terminal has appeared within a predetermined distance during the content reproduction through the notification window 910. [0064] FIG.

9B shows an operation in which the mobile terminal 100 controls the external display device 900 to reproduce the content. As described above, the mobile terminal 100 can use the DLNA technology to control the external display device 900 to reproduce and provide the content. That is, when the partner terminal appears in the vicinity of the mobile terminal 100, the user of the partner terminal and the user of the mobile terminal 100 can control to watch the content together through the external display device 900. [

In the description of Figs. 5 to 9, the embodiments for changing the content reproduction mode may be individual, but the embodiments may be combined and executed. For example, the change to the view mode, which is the first embodiment, and the playback state adjustment mode, which is the fourth embodiment, may be performed in combination. That is, when the other party's terminal appears within a certain distance, it may be changed to the view mode and the voice state may be canceled.

Also, in the above description, the case where the position of the mobile terminal 100 is stopped and the other terminal approaches the mobile terminal 100 has been described. However, the present invention is not limited to this case. For example, when the mobile terminal 100 is in the moving state, the location information module 115 of the mobile terminal 100 continuously checks the changed current location information of the mobile terminal 100, The content reproduction control method may be changed and determined.

10 is a diagram illustrating a content control method when the mobile terminal moves according to the present invention.

The mobile terminal 100 of the present invention may change the content control method according to the location conversion of the mobile terminal 100. [

The mobile terminal 100 of the present invention may store location information of various places in the memory 160. [ For example, various location information such as location information of a user's home, location information of a company, location information of a shop, and the like can be stored in the memory 160. By using the location information of the various places, it is possible to confirm whether the mobile terminal 100 is currently moving and where the current location is located. The control unit 180 may change the content playback mode using the current location information of the mobile terminal 100 and location information of various locations acquired through the location information module 115. [

10 is a diagram showing an operation of the mobile terminal 100 to repeat the content displayed on another device in accordance with the change of the location information.

10 (a) is a diagram showing an operation of playing a specific content 1010 in an external display apparatus 1000 such as a TV at home. In this case, the location information of the mobile terminal 100 coincides with the location information of the house.

10 (b) shows a case where the mobile terminal 100 moves away from home and moves to another position. The location information of the mobile terminal 100 and the location information of the house are different from each other. In this case, the mobile terminal 100 can reproduce the content displayed on the external display device 1000 in association with the content reproduction. When the control unit 180 confirms the change of the location information, the display unit 151 can ask the user whether the location information is changed or not.

10C, the display unit 151 can reproduce the content reproduced in the external display device 1000 when the user selects the mode for the earliest viewing. Through this function, it is possible to continuously view the content that has been played back despite the position change of the mobile terminal 100. [

On the contrary, when there is a content that is being played back through the display unit 151 of the mobile terminal 100 during the movement, when one of the external display devices located at the home is selected So that the content reproduced by the mobile terminal 100 can be displayed on the external display device.

11 is a diagram illustrating a method of managing content information of a mobile terminal according to the present invention.

When the controller 180 determines that the counterpart terminal is located within a predetermined range in the vicinity of the mobile terminal 100, the controller 180 may stop the playback of the content played back on the display unit 151 have. Here, the control unit 180 may control the memory 160 to store information on the playback status in which the content was played back. In addition, the information on the playback status may be stored in the content management list. The content management list may include playback information for various contents. That is, in the case where the reproduction is stopped during the reproduction as described above, the content management list may be set to store the reproduction status information together with the content.

The content management list may be managed in association with the time and place for each content. This will be described below with reference to FIG.

11 (a), the mobile terminal 100 displays various contents 1111 to 1117 in a content management list. The content management list may be set by the user in various ways. Each content is represented by information associated with time or place. For example, the first content 1111 is content set to be reproduced when it is located at the A place, and the second, third, fourth, and fifth contents 1112, 1113, 1114, and 1115 are time- And the sixth content 1116 is content set to be reproduced at 22:00 to 24:00, located at the B place in association with the time and place. On the other hand, the content for which the time and place are not set can be set to be reproduced each time the mobile terminal 100 is turned on. For example, the seventh content 1117 may be set to be reproduced when the mobile terminal 100 is turned on.

Since the mobile terminal 100 can check the current location information of the mobile terminal 100 through the location information module 115 and check the current time, So that the content can be reproduced.

11B is a view showing an operation in which the first content 1111 set to be reproduced at the A place is reproduced from the content management list when the mobile terminal 100 is located at the A place. Since the first content 1111 is time-independent, it can be reproduced when it is located at the A place regardless of the time.

11 (c), the mobile terminal 100 is located at the place B and the current time is 22:22. From the content management list, the content in which the mobile terminal 100 is located at the location B and is reproduced from 22:00 to 24:00 is the sixth content 1116, so that the control unit 180 can reproduce the content.

On the other hand, in the content information management, when the specific content is stopped during reproduction, information on the reproduction status of the content may be stored as information on the specific content. Here, in the case where the device for reproducing the content is a third external display device (TV, PC monitor, etc.) other than the mobile terminal 100, even if the external display device stops during the content reproduction, May be stored in the mobile terminal 100. In the content information management, the order of the content to be reproduced may be changed by the user.

Further, according to an embodiment of the present invention, the above-described display control method can be implemented as a code that can be read by a processor on a medium on which a program is recorded. Examples of the medium that can be read by the processor include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, etc., and may be implemented in the form of a carrier wave (e.g., transmission over the Internet) .

The mobile terminal described above can be applied to not only the configuration and method of the embodiments described above but also all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments It is possible.
