5 to 13, when a call reception event occurs in the mobile terminal 100 while sharing the video and sound of the media being played in the mobile terminal 100 through an external device according to the present invention, The process of switching the notification method of occurrence of the event and controlling the operation of the external device will be described in detail so as not to disturb the viewing of the media through the external device.

5 is a flowchart illustrating a process of controlling notification output switching of a call reception event generated and media output operation of an external device while sharing media being played with an external device according to the present invention.

Referring to FIG. 5, first, in response to a user's command input or event generation, the controller 180 activates a sharing mode for outputting an image and sound of a media currently being played to an external device, and connects an external device and media. A data path for sharing video and sound can be set [S110].

The user's command input includes selection of a menu or icon through the user input unit 130, touch input of a predetermined pattern, manipulation of a specific key button, and the like. In addition, according to the present invention, the user's command input may be a command for playing the media provided in the memory 160 or uploaded to an external website.

In addition, when an event is detected, when a connectable external device is detected, when a connection request is received from a connectable external device, and when a connection according to a predetermined protocol is detected by the interface unit 170 (eg, wired communication). Cable plug detection, etc.);

The process of setting a data path for sharing the image and sound of the media being played with the external device may include searching for an external device that can be connected to the controller 180 through the wireless communication unit 110 and / or the interface unit 170, and searching. The result may be displayed on the display unit 151, and if the user inputs a selection command through the user input unit 130, the result may include connecting to an external device corresponding to the selection command. Of course, the controller 180 may select a device to be automatically connected according to a preset criterion without a user selection command.

The controller 180 plays a media corresponding to the input command when a media sharing mode is activated with the external device and a play command of a specific media is input from the user through the touch screen 151 or the user input unit 130. [S120], the image and sound of the media are transmitted to the external device through the wireless communication unit 110 so that the image and sound of the media being played are output from the external device [S130].

In this case, the media may be previously stored in the memory 160 or uploaded to an external website connected through the wireless communication unit 110.

In addition, the media may be played in advance before the media sharing mode with the external device is activated, or may be played after the media sharing mode with the external device is activated in step S120.

The controller 180 detects whether a call reception event occurs in the portable terminal 100 while sharing the image and sound of the media being played with the external device [S140].

If the call reception event occurs as a result of the detection [S150], the controller 180 displays a screen image related to the call reception event on the touch screen 151 and controls the alarm unit 153 to control the call. As a notification method of the reception event, the ring mode previously set by the user is automatically switched to the vibration mode [S160].

In addition, the controller 180 maintains the media image and sound sharing operation with the external device during the call reception event notification period during which the vibration sound according to the vibration mode is output through the alarm unit 153 [S170]. .

That is, if a call reception event occurs in which a call is received from a specific counterpart while the mobile terminal 100 shares the video and sound of the media being played with the external device, the call is missed or the call is made with the counterpart. The media sharing mode with the external device is stopped until the connection is terminated, or the call-related screen image is transmitted to the external device for display instead of the image of the media while maintaining sound sharing of the media. .

Therefore, the user cannot watch the media through the external device until the call reception event generated in the mobile terminal 100 is completely terminated.

In addition, conventionally, when the ring mode is set as a notification method of the call reception event in the mobile terminal 100, a notification period (a period during which the user receives a call or an incoming call is missed) has elapsed. Since the ringtone is output from the mobile terminal 100 until it is, there is a problem that even the sound of the media currently being output from the external device is disturbed.

In order to solve this problem, the mobile terminal 100 according to the present invention, if a call reception event occurs while sharing the image and sound of the media with the external device, the external terminal during the notification period of the generated call reception event By maintaining the video and sound sharing operation of the media with the device as it is, and automatically switching the preset ringtone mode to the vibration mode as a notification method of the event, it does not interfere with the user's viewing of the media through the external device.
