Abstract

A source device includes an event processing unit processing an event which occurs in a remote sink device that communicates through a WLAN, a control unit setting an event management area of the sink device, and a determination unit determining whether the event transferred from the sink device has occurred in the event management area and outputting the event to the event processing unit when the event has occurred in the event management area.

Claims

1. A source device to transmit media data, the source device comprising:

an event processing unit configured to process an event that occurs in a remote sink device communicating through a network;

a control unit configured to set an event management area of the sink device, wherein the event management area is an area on a screen of the sink device pre-selected by a user to be effective for transmitting event requests, wherein the pre-selected area can be moved, expanded and contracted according to the user; and

a determination unit configured to determine whether the event transferred from the sink device has occurred in the event management area and configured to output the event to the event processing unit when the event has occurred in the event management area.

2. The source device of claim 1, wherein the network comprises a Wireless Local Area Network (WLAN).

3. The source device of claim 1, further comprising a storage unit configured to store sink device information, event management area information and event information.

4. The source device of claim 1, further comprising a selection providing unit configured to select the event management area.

5. The source device of claim 4, wherein the selection providing unit is further configured to overlap a current screen of the source device with a selection screen in which a selection is receivable.

6. The source device of claim 4, wherein the selection providing unit further comprises an object selection unit configured to select an object including an event listener.

7. The source device of claim 4, wherein the selection providing unit further comprises an object determination unit configured to search for an object including an event listener.

8. The source device of claim 4, wherein the selection providing unit further comprises an arbitrary area selection unit configured to display a selection screen to select the event management area.

9. The source device of claim 1, wherein the event management area comprises menus for one or more of event permission area setting, event permission object setting and event permission area storage.

10. A method utilizing a processor, the method comprising:

processing an event that occurs in a remote sink device communicating through a network;

setting an event management area of the sink device, wherein the event management area is an area on a screen of the sink device pre-selected to be effective for transmitting event requests, wherein the pre-selected area can be moved, expanded and contracted according to the user;

determining, utilizing the processor, whether the event that is transferred from the sink device has occurred in the event management area; and

outputting the event to the event processing unit when the event has occurred in the event management area.

11. The method of claim 10, wherein the network comprises a Wireless Local Area Network (WLAN).

12. The method of claim 10, further comprising storing sink device information, event management area information and event information.

13. The method of claim 10, further comprising selecting the event management area.

14. The method of claim 13, wherein the selecting further comprises overlapping a current screen of the source device with a selection screen in which a selection is receivable.

15. The method of claim 13, wherein the selecting further comprises selecting an object including an event listener.

16. The method of claim 13, wherein the selecting further comprises searching for an object including an event listener.

17. The method of claim 13, wherein the selecting further comprises a selection screen to select the event management area.

18. The method of claim 10, wherein the event management area comprises menus for one or more of event permission area setting, event permission object setting and event permission area storage.

19. A wireless local area network (WLAN), the WLAN comprising:

a sink device; and

a source device comprising;

an event processing unit configured to process an event that occurs in a remote sink device communicating through a network,

a control unit configured to set an event management area of the sink device, wherein the event management area is an area on a screen of the sink device pre-selected to be effective for transmitting event requests, wherein the pre-selected area can be moved, expanded and contracted according to the user, and

a determination unit configured to determine whether the event transferred from the sink device has occurred in the event management area and configured to output the event to the event processing unit when the event has occurred in the event management area.

20. The WLAN of claim 19, wherein the determination unit is further configured to output the event to the event processing unit only when the event has occurred in the event management area.
