Abstract

An apparatus and method for providing a screen mirroring service. The apparatus includes a communication unit for connecting to an external device; and a control unit for generating a plurality of screen data, transmitting one of the plurality of screen data to the external device, and controlling the screen data being transmitted to the external device according to a control signal received from the external device.

First claim

What is claimed is:

1 . An electronic device for providing a screen mirroring service, the device comprising:
a communication unit configured to connect to an external device; and a control unit configured to generate a plurality of screen data, transmit one of the plurality of screen data to the external device, and control the screen data being transmitted to the external device according to a control signal received from the external device.

2 . The electronic device of claim 1 , further comprising a display unit displaying another one of the plurality of screen data.

3 . The electronic device of claim 2 , wherein the plurality of screen data are screen data each corresponding to different respective functions executed by the electronic device.

4 . The electronic device of claim 2 , wherein the plurality of screen data are different screen data each corresponding to execution of a same function in the electronic device.

5 . The electronic device of claim 1 , wherein the plurality of screen data comprises a first screen data and a second screen data.

6 . The electronic device of claim 5 , wherein the first screen data and the second screen data have different resolutions.

7 . The electronic device of claim 5 , wherein the first screen data has image pixel coordinates of a first range, and the second screen data has image pixel coordinates of a second range, and at least a part of the image pixel coordinates of the second range is the same as at least a part of the image pixel coordinates of the first range.

8 . The electronic device of claim 5 , wherein the first screen data is related to a first application program, and the second screen data is related to a second application program.

9 . The electronic device of claim 5 , wherein the first screen data is related to a first operation of a first application program, and the second screen data is related a second operation of the first application program.

10 . The electronic device of claim 5 , wherein the first screen data comprises media data provided through a first application program, and the second image frame data comprises a user interface of the first application program.

11 . A method for providing a screen mirroring service in an electronic device, the method comprising:
connecting to an external device; generating a plurality of screen data; transmitting one of the plurality of screen data to the external device; and controlling the screen data being transmitted to the external device according to a control signal received from the external device.

12 . The method of claim 11 , further comprising displaying another one of the plurality of screen data.

13 . The method of claim 12 , wherein the plurality of screen data are screen data each corresponding to different respective functions executed by the electronic device.

14 . The method of claim 12 , wherein the plurality of screen data are different screen data each corresponding to execution of a same function in the electronic device.

15 . The method of claim 11 , wherein the plurality of screen data are different screen data each corresponding to execution of a same function in the electronic device.

16 . The method of claim 15 , wherein the first screen data and the second screen data have different resolutions.

17 . The method of claim 15 , wherein the first screen data has image pixel coordinates of a first range, and the second screen data has image pixel coordinates of a second range, and at least a part of the image pixel coordinates of the second range is the same as at least a part of the image pixel coordinates of the first range.

18 . The method of claim 15 , wherein the first screen data is related to a first application program, and the second screen data is related to a second application program.

19 . The method of claim 15 , wherein the first screen data is related to a first operation of a first application program, and the second screen data is related a second operation of the first application program.

20 . The method of claim 15 , wherein the first screen data comprises media data provided through a first application program, and the second screen data comprises a user interface of the first application program.
