Abstract

Disclosed is a display control apparatus and method in a mobile terminal capable of outputting video data to an external display device, which implements a function of using other services in the mobile terminal, separately from the service provided to the external display device connected with the mobile terminal. To accomplish the above function, the controller determines whether an event occurs or not during displaying video data sent by the mobile terminal on the external display device and upon occurrence of an event, displays a screen for processing the event on the mobile terminal. Thus, a user can enjoy concurrent service by using other services through the mobile terminal while continuing to watch video data currently being displayed on the external display device. In addition, irrespective of the screen of the external display device, information relative to the event is only displayed on the mobile terminal so that a user'"'"'s privacy can be fully protected.

Claims

1. A display control method in a mobile terminal capable of outputting video data to an external display device, the method comprising the steps of:

wirelessly transmitting, by the mobile terminal, video data to be displayed on the external display device;

determining whether an event occurs while displaying the video data on the external display device;

upon occurrence of the event, displaying a sender/caller identifying event indicator at a screen of the mobile terminal device; and

displaying a sender/caller non-identifying event indicator at an edge of a screen of the external display device while the video data is being displayed on the external display device, wherein the event comprises one of a receipt of a text message and a receipt of a phone call, and wherein, the sender/caller identifying event indicator comprises a sender identification and contents of the text message if the event is the receipt of the text message, and the sender/caller identifying event indicator comprises a caller identification or a caller number if the event is the receipt of the phone call.

2. The method as set forth in claim 1, wherein the event indicator is displayed at the bottom of the screen of the external display device.

3. The method as set forth in claim 1, wherein the video data includes at least one of broadcasting data received in real time and moving pictures stored in advance.

4. The method as set forth in claim 1, wherein the video data is transmitted to the external display device through an interface.

5. The method as set forth in claim 4, wherein the interface uses at least one of cable, infrared data communication, Bluetooth, USB, IEEE 1394, Zigbee, and wireless Local Area Network (LAN).

6. The method as set forth in claim 2, wherein the event indicator is displayed to overlap only a slight portion of the screen.

12. The method as set forth in claim 1, wherein the external display device is not a mobile terminal

7. A display control apparatus in a mobile terminal capable of outputting video data to an external display device, the apparatus comprising:

a controller for wirelessly transmitting the video data through an interface to display the video data on the external display device, for determining whether an event occurs while displaying the video data on the external display device, for determining whether an event occurs while displaying the video data on the external display device, for, upon determination of occurrence of the event, controlling display of a sender/caller identifying event indicator at a screen of the mobile terminal device, and for controlling display of sender/caller non-identifying event indicator at an edge of a screen of the external display device while the video data is being displayed on the external display device; and

a display units for displaying the sender/caller identifying and sender/caller non-identifying event indicators, wherein the event comprises one of a receipt of a text message and a receipt of a phone call, and wherein, the sender/caller identifying event indicator comprises a sender identification and contents of the text message if the event is the receipt of the text message, and the sender/caller identifying event indicator comprises a caller identification or a caller number if the event is the receipt of the phone call.

8. The apparatus as set forth in claim 7, wherein the controller controls to display the event indicator at the bottom of the screen of the external display device.

9. The apparatus as set forth in claim 7, wherein the video data includes at least one of broadcasting data received in real time and moving pictures stored in advance.

10. The apparatus as set forth in claim 9, further comprising a Digital Multimedia Broadcasting (DMB) receiver for receiving broadcasting data received from a digital broadcasting station in real time.

11. A display control apparatus in a mobile terminal capable of outputting video data to an external display device, the apparatus comprising:

a Digital Multimedia Broadcasting (DMB) receiver for receiving broadcasting data from a digital broadcasting station in real time;

a controller for wirelessly transmitting the broadcasting data to be displayed on the external display device through an interface, for determining whether an event occurs while displaying the video data on the external display device, for, upon determination of occurrence of the event, controlling display of a sender/caller identifying event indicator at a screen of the mobile terminal device, and for controlling display of sender/caller non-identifying event indicator at an edge of a screen of the external display device while the video data is being displayed on the external display device; and

a display units for displaying the sender/caller identifying and sender/caller non-identifying event indicators, wherein the event comprises one of a receipt of a text message and a receipt of a phone call, and wherein, the sender/caller identifying event indicator comprises a sender identification and contents of the text message if the event is the receipt of the text message, and the sender/caller identifying event indicator comprises a caller identification or a caller number if the event is the receipt of the phone call.
