5. The mobile terminal of claim 4, wherein the controller is further configured to control the external display device to control an orientation direction of the monitor window displayed on the second display unit to automatically match with a display direction of the multimedia content displayed on the first display unit.

6. The mobile terminal of claim 5, wherein when the multimedia content is displayed in a portrait direction on the first display unit, the controller is further configured to control the external display device to control the monitor window to be oriented in a vertical direction, and

wherein when the multimedia content is displayed in a landscape direction on the first display unit, the controller is further configured to control the external display device to control the monitor window to be oriented in a horizontal direction on the second display unit.

7. The mobile terminal of claim 4, wherein the controller is further configured to control the external display device to display the monitor window according to whether or not the external display device is connected to an auxiliary display device.

8. The mobile terminal of claim 7, wherein when the external display device fails to be connected to the auxiliary display device is connected, the controller is further configured to control the external display device to display the monitor window on the second display unit.

9. The mobile terminal of claim 7, wherein when the external display device is connected to the auxiliary display device and an image of the auxiliary display device is identical to that of the external display device, the controller is further configured to control the external display device not to display the monitor window, and

wherein when the image of the auxiliary display device is not identical to that of the external display device, the controller is further configured to control the external display device to display the monitor window on the second display unit.

10. The mobile terminal of claim 1, wherein the controller is further configured to transmit an identifier of the multimedia content to the external display device and to control the external display device to retrieve additional information about the multimedia content using the identifier and display the additional information on the second display unit.

11. The mobile terminal of claim 1, wherein when the mobile terminal is playing the multimedia content on the first display unit and another function is executed on the mobile terminal, the controller is further configured to continuing playing the multimedia content and to display information corresponding to said another function on the first display unit, and to control the external display device to simultaneously display the multimedia content in a first window and the information corresponding to said another function in a second window on the second display unit.

12. A display device, comprising:

an interface unit configured to be connected to an external mobile terminal having a first display unit;

a second display unit; and

a controller configured to receive a connection signal indicating a connection of the display device to the external mobile terminal, to receive video information of multimedia content being displayed on the first display unit of the external mobile terminal, and to control the external mobile terminal then to pause the playing of the multimedia content on the first display unit for a predetermined amount of time.

13. The display device of claim 12, wherein the controller is further configured to check if the display device includes a play authority authorizing the display device to play the multimedia content, and to control the external mobile terminal to pause the playing of the multimedia content on the first display unit when the display device does not include the play authority of the multimedia content.

14. The display device of claim 12, wherein the controller is further configured to receive a disconnection signal indicating the connection between the display device and the external mobile terminal is disconnected, and to control the external mobile terminal to pause the play of the multimedia content on the first display unit.

15. The display device of claim 12, wherein the controller is further configured to display a monitor window for displaying the multimedia content on the second display unit, when the display device is connected to the external mobile terminal.

16. The display device of claim 15, wherein the controller is further configured to control an orientation direction of the monitor window displayed on the second display unit to automatically match with a display direction of the multimedia content displayed on the first display unit.

17. The display device of claim 16, wherein when the multimedia content is displayed in a portrait direction on the first display unit of the external mobile terminal, the controller is further configured to control the monitor window to be oriented in a vertical direction, and

wherein when the multimedia content is displayed in a landscape direction on the first display unit of the external mobile terminal, the controller is further configured to control the monitor window to be oriented in a horizontal direction on the second display unit.
