Done. Specific examples thereof will be described later.

Alternatively, when the controller 180 of the mobile communication terminal 100 inputs a play command to the multimedia file, the controller 180 displays a reference menu for selecting the optimal external device on the display unit 151 and the reference menu. When a predetermined criterion is selected by using, the optimum external device is determined based on the selected criterion, the multimedia file is transmitted, and a reproduction control command is transmitted.

The reference included in the reference menu may include at least one of a type of the multimedia file, a playback time of the multimedia file, a reception sensitivity of an external device, a priority of a user setting, and a distance to the external device.

In addition, if it is impossible to play the multimedia on the external device, the controller 180 transmits the multimedia file data and a playback control command thereto to the other external device so that another external device is selected to play the multimedia file. Done. This will be described later.

According to the exemplary embodiment of the present invention having the above-described configuration, the user can automatically play the multimedia file of the external device and the internal memory connected by DRLA through the mobile communication terminal in the optimal playback device (external device). .

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. 5, which is an image diagram of a mobile communication terminal to which the above-described multimedia file reproduction method using the mobile communication terminal is applied.

FIG. 5 is an image diagram of a first application example of a mobile communication terminal to which a display control method of multimedia data through a mobile communication terminal, which is an embodiment of the present invention, is applied.

5A shows the main menu screen 210. The submenu 211 of the main menu is displayed on the menu screen 210. When the user enters the connection menu 211-1, which is one of the sub-menus, the connection menu screen 220 is displayed on the display unit 151 as shown in FIG. 5B. When the user selects the home network connection 221 which is a submenu of the connection menu, the controller 180 displays the home network connection menu screen 230 on the display unit 151 (see FIG. 5C). The home network connection menu screen 230 may include a kitchen appliance control menu 231, a door control menu 232, and a multimedia file playback menu 233.

When the user selects the multimedia file play menu 233 through the user input unit 130, the multimedia file list 250 stored in the external device and the internal memory 160 is displayed on the display unit 151. Is displayed (see FIG. 5D). Each item of the file list is a multimedia file, and may indicate the type of file and a file storage location. Here, when the user selects a multimedia file (here, an audio file) 251 which is one of the multimedia file lists 250, the controller 180 displays the connection reference screen 260 on the display unit (FIG. 5E). Reference). The connection reference screen 260 may include a reception sensitivity icon 261, a genre icon 262, a modest connection icon 263, a user icon 264, and an automatic icon 265.

When the reception sensitivity icon 261 is selected, an optimum external device is selected based on the reception sensitivity, and the multimedia file and playback control command are transmitted to the selected external device.

When the genre icon 262 is selected, an optimal external device is selected based on the content genre of the multimedia file, and the multimedia file and playback control command are transmitted to the selected external device. For example, when the multimedia file is a movie, it can be played on a TV having a large display unit, and when the multimedia file is an audio file, it can be played on an audio device (MP3 player). When the genre icon 262 is selected, as shown in FIG. 5F, the external device confirmation message screen 270 is displayed on the display unit 151, and when the user selects the OK icon 271, the audio device is selected. When the multimedia file is played and the rejection icon 272 is selected, the multimedia file is returned to the connection reference screen 260.

When the least frequently connected icon 263 is selected, an external device selected by the user is automatically selected as an optimal external device for a predetermined period of time, and the multimedia file and playback control command are transmitted to the least frequently external device.

When the user icon 264 is selected, the multimedia file and playback control command are transmitted to an external device preset by the user.

When the automatic icon 265 is selected, the controller 180 is selected in consideration of the reception sensitivity, the type and resolution of the multimedia file, the status information of the external device (memory status, battery status, CPU status, etc.), the frequency of use of the user, and the like. Determine the optimal external device for the multimedia file.

As shown in Figs. 5D and 5E, in this embodiment, a music file (audio file) is selected, and a genre is selected as a selection criterion. Therefore, in the home network environment of FIG. 3, the audio player 500 is selected as an external device. Accordingly, the controller 180 of the mobile communication terminal 100 transmits the audio file stored in the PC 600 to the audio player 500 and transmits a reproduction control command of the audio file. Then, the music file is played in the audio player 500.

Meanwhile, when the multimedia file is no longer reproduced by the external device due to a predetermined event while the multimedia file is being played, as shown in FIG. 5G, the controller 180 of the mobile communication terminal 100 is external. The device change message 280 is displayed on the display unit 151. In this case, the external device may transmit device state information for displaying the change message 280, and the controller 180 may periodically check the state of the external device.

On the other hand, when the OK icon 281 included in the external device change message 280 is selected, the multimedia file is played on a next-order optimal external device, and when the reject icon 282 is selected, the optimal external device is selected. The multimedia file will continue to play.

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

The above-described method and method for reproducing a multimedia file using the mobile communication terminal and the mobile communication terminal using the same are not limited to the configuration and method of the above-described embodiments, but the embodiments may be modified in various ways.
