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, a device selection menu 240 for selecting a device in which the multimedia file is stored is displayed on the display unit 151. do. The device displayed here is an external device having a memory capable of storing multimedia files in FIG. 3 and may be a PC, a DVD, a camera, or the like.

In the first application example, the memory menu 241 is selected, but this is only one example. Then, as shown in FIG. 5E, the multimedia file table 250 stored in the memory 160 is shown on the display unit 151. As shown, the multimedia file table 250 includes a multimedia file item 251 and a playable external device item 252. In the example shown, I love you. The MP3 251-1 is an audio file that can be played back on a PC or an audio player. Mucin.avi 251-2 is a video file that can be played on a TV, a PC, or a camera. That is, the TV or the like has a program capable of playing avi files, and a codec. The son of the general.mpg (251-3) can only be run on a PC. When the icon shown in the external device item 252 is selected, the selected file is played on the selected external device. That is, the file stored in the memory 160 is transmitted to the external device, and the external device executes the transferred file to play the multimedia file selected on the display unit of the external device.

On the other hand, if the status information acon 253 is selected, as shown in FIG. 5F, status information for each device is displayed. As shown, battery remaining amount information, CPU status information, memory capacity information, and overall status information are displayed. These data are data automatically received while the external device is connected through the router 200. At least some of the information may be pre-stored information (eg memory). In this case, the status information is an item for evaluating an external device suitable for playing the selected multimedia file.

By displaying such state information on the display unit 151, the user can select an optimal external device in multimedia data reproduction. Alternatively, the controller 180 may automatically select an optimal external device for the selected multimedia data and display it on the display unit (see FIG. 6).

Second Application Example

FIG. 6 is an image diagram of a second 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.

6A is a diagram for describing a case in which the controller 180 of the mobile communication terminal 100 automatically sets an optimal external device. As described with reference to FIG. 5, when the controller 180 determines an optimum external device of the multimedia data selected by the user, as illustrated in FIG. 6A, the screen 310 including the optimum icon notification message 311 of the controller 180 is shown. ) Is displayed on the display unit 151. The optimal icon notification message 311 includes a yes icon 311-1 and a no icon 311-2. When the user selects the yes icon 311-1, the controller 180 transmits control command information to the TV through the router 200 such that the multimedia data selected by the user is played on the TV (external device determined by the controller). Done.

FIG. 6B is a diagram for describing an example in which the controller 180 of the mobile communication terminal 100 automatically notifies when an external device selected by a user is not suitable. As described with reference to FIG. 5, when the user selects the multimedia data and the external playback device, the controller 180 checks whether the selected external device is suitable for playing the multimedia data. In this case, previously received device information may be used. When the controller 180 determines that the selected external device is not suitable, the controller 180 displays a warning message 320 indicating this on the display unit 151. At this time, it is possible to add an unsuitable reason (for example, impossible to reproduce due to resolution, total playback impossible by comparing battery time with multimedia playback time). If the yes icon 320-1 is selected, multimedia data is played on the external device. On the other hand, if the no icon 320-2 is selected, the table of FIG. 5E is displayed on the display unit 151, so that the user can select a playable external device.

6C is a view for explaining another example in which the controller 180 of the mobile communication terminal 100 automatically notifies the user when an external device selected by the user is not suitable. As described with reference to FIG. 5, when the user selects the multimedia data and the external playback device, the controller 180 checks whether the selected external device is suitable for playing the multimedia data. In this case, previously received device information may be used. When the controller 180 determines that the current state of the selected external device is not appropriate, the controller 180 displays a warning message 330 informing the user of the warning on the display unit 151. That is, since the current CPU state is busy, a time delay is expected when playing multimedia data. At this time, an external device to be replaced can be proposed. If the yes icon 330-1 is selected, multimedia data is played on the substitute external device. On the other hand, if the no icon 330-2 is selected, the table of FIG. 5E is displayed on the display unit 151, so that the user can select a playable external device.
