For example, when the counterpart terminal appears while playing the content, it may be controlled to display the corresponding content on an external display device having a wide screen.

There may be various ways for the mobile terminal 100 to play content using the third display device. For example, Digital Living Network Alliance (DLNA) technology may be used. DLNA technology refers to a technology that is compatible with devices that allow various contents stored in a PC or a mobile phone to be displayed on a display device such as a TV using a network.

In general, a storage device such as a PC or a server can store various media. Although these various media may be transmitted to other devices, the media streams of the media may be provided to the display apparatus to be displayed on the display apparatus. In DLNA technology, a device that stores media is called a DMS (Digital Media Server). A device acting as a DMS is a data storage device with a large storage capacity.

In addition, in DLNA technology, a device that displays media stored in a DMS is a digital media renderer (DMR), and a device having a control function for displaying media stored in the DMS is a digital media controller (DMC). All. The device acting as a DMR is a device having a display function such as a TV or a monitor because the device can display the media.

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

In the present invention, the DMS serving to store the content may be the mobile terminal 100 or may be a third content storage server. When the mobile terminal 100 serves as a DMS, content may be provided to an external display device through the wireless communication unit 110 of the mobile terminal 100. In addition, when the third content storage server serves as a DMS, the third content storage server may be controlled to provide content to the external display device from the third content storage server under the control of the mobile terminal 100.

As described above, the mobile terminal 100 can control the external display apparatus 900 to provide and reproduce the content by using DLNA technology. That is, when the counterpart terminal appears in the vicinity of the mobile terminal 100, the user of the counterpart terminal and the user of the mobile terminal 100 may view the content together through the external display device 900.

5 to 9, embodiments for changing the content playback mode may be individual, but the embodiments may be combined and executed. For example, the change to the viewing mode together as the first embodiment and the playback state adjustment mode as the fourth embodiment may be performed in combination. That is, when the counterpart terminal appears within a certain distance, it may be adjusted to change to the viewing mode at the same time and to cancel the voice state.

In addition, in the above description, it has been described that the position of the mobile terminal 100 is in a stationary state and the counterpart terminal approaches the mobile terminal 100. However, the present invention is not limited to this case. For example, when the mobile terminal 100 is in the mobile state, the location information module 115 of the mobile terminal 100 continuously checks the changed current location information of the mobile terminal 100, and the counterpart terminal is determined based on the changed information. In the case of getting closer, the content reproduction control method can be changed and determined.

Here, the controller 180 may control to store the information on the playback state in which the content was played in the memory 160. In addition, the information on the reproduction state may be included in the content management list and stored. The content management list may include reproduction information about various contents. That is, in the case where the playback is interrupted as described above, the content management list may be set to store the reproduction state information for the corresponding content.

In addition, the content management list may be managed in association with time and place for each content. This will be described below with reference to FIG. 11.

In FIG. 11A, the mobile terminal 100 displays various contents 1111 to 1117 in a content management list. The content management list may be set in various ways by the user. Each content is represented by information associated with a time or place. For example, the first content 1111 is content set to be played when the location A is located in the A place, and the second, third, fourth, and fifth contents 1112, 1113, 1114, and 1115 are related to time and are independent of the place. The sixth content 1116 is content set to be played at 22:00 to 24:00 and is located at place B in association with time and place. On the other hand, content that does not set the time and place may be set to be played whenever the mobile terminal 100 is turned on. For example, the seventh content 1117 may be set to be played 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, the mobile terminal 100 corresponds to the corresponding place or time with respect to the content management list information. It can be set to play the content.

In FIG. 11B, when the mobile terminal 100 is located at location A, the first content 1111 set to be reproduced at the location A is reproduced from the content management list. Since the first content 1111 is time-independent, it can be played when it is located at the A location regardless of time.

In FIG. 11 (c), the mobile terminal 100 is located at a location B and the current time is 22:22. From the content management list, since the mobile terminal 100 is located at place B and is played at 22:00 to 24:00, the content is the sixth content 1116, so that the controller 180 can play the corresponding content.

On the other hand, in the content information management, when stopped during the playback of a specific content, information about the reproduction state of the corresponding content may be stored as information about the specific content. In this case, when the device that plays the content is a third external display device (TV, PC monitor, etc.) other than the mobile terminal 100, information on the content playback state even when the external display device is stopped during content playback. May be stored in the mobile terminal 100. In addition, in the content information management, the order of the content to be played back may be changed by the user.

In addition, according to an embodiment of the present invention, the above-described display control method may be implemented as code that can be read by a processor in a medium in 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.
