Abstract

A wireless device according to an embodiment of the present disclosure may receive a mirroring request for a screen sharing service from an external device, may determine whether a transmission condition of a content image is satisfied according to the received mirroring request, and, when the transmission condition is satisfied, to transmit content image data corresponding to the content image and OSD image data corresponding to an OSD image to the external device through a wireless communication interface.

First claim

What is claimed is:

1. A wireless device comprising:
a display configured to display a content image and an On Screen Display (OSD) image including a plurality of items corresponding to a plurality of applications installed in the wireless device;
a wireless communication interface configured to communicate with an external device wirelessly; and
a processor configured to:
receive a mirroring request for a screen sharing service from the external device,
determine whether a transmission condition of the content image is satisfied according to the received mirroring request,
based on determining that the transmission condition is satisfied, transmit content image data corresponding to the content image and OSD image data corresponding to the OSD image to the external device through the wireless communication interface, and
based on determining that the transmission condition is not satisfied, transmit the OSD image data corresponding to the OSD image to the external device through the wireless communication interface,
wherein the processor is further configured to:
receive coordinate information from the external device;
select an item existing at a point corresponding to the coordinate information from the plurality of items; and
execute an application of the plurality of applications that corresponds to the selected item.

2. The wireless device of claim 1 , wherein the processor is further configured to determine that the transmission condition is satisfied when the external device supports a mirroring sink mode in which the external device receives and displays a displayed image.

3. The wireless device of claim 1 , wherein the processor is further configured to determine that the transmission condition is satisfied when authentication for content protection of the content image succeeds.

4. The wireless device of claim 3 , wherein the processor is further configured to determine that the authentication for the content protection succeeds when a first message received from the external device is same as a second message generated by the wireless device,
wherein the first message is a message that is generated based on a public key of the external device, a public key of the wireless device, and a private key of the external device, and
wherein the second message is a message that is generated based on the public key of the external device, the public key of the wireless device, and a private key of the wireless device.

5. The wireless device of claim 1 , wherein the processor is further configured to determine that the transmission condition is satisfied when the external device supports a mirroring sink mode in which the external device receives and displays a displayed image, and authentication for content protection of the content image succeeds.

6. The wireless device of claim 1 , wherein the processor is further configured to receive the coordinate information through a User Input Back Channel (UIBC).

7. The wireless device of claim 1 , wherein the processor is further configured to provide the screen sharing service in any one connection mode of a first connection mode where the wireless device is connected with the external device through a router, or a second connection mode where the wireless device is directly connected with the external device without the router.

8. A wireless device comprising:
a display;
a wireless communication interface configured to wirelessly communicate with an external device which displays a content image and an On Screen Display (OSD) image including a plurality of items corresponding to a plurality of applications installed in the external device; and
a processor configured to:
transmit a mirroring request for a screen sharing service to the external device,
determine whether a transmission condition of the content image is satisfied,
based on determining that the transmission condition is satisfied:
receive content image data corresponding to the content image and OSD image data corresponding to the OSD image from the external device through the wireless communication interface, and
display a content mirroring image based on the content image data and display an OSD mirroring image based on the OSD image data on the display, and
based on determining that the transmission condition is not satisfied:
receive the OSD image data corresponding to the OSD image from the external device through the wireless communication interface, and
display the OSD mirroring image based on the OSD image data,
wherein the processor is further configured to:
receive a user input of selecting one of the plurality of items, and
transmit coordinate information of a point where the user input is received to the external device.

9. The wireless device of claim 8 , wherein the processor is further configured to determine that the transmission condition is satisfied when the external device supports a mirroring sink mode in which the external device receives and displays an image displayed by the external device.

10. The wireless device of claim 8 , wherein the processor is further configured to determine that the transmission condition is satisfied when authentication for content protection of the content image succeeds.

11. The wireless device of claim 10 , wherein the processor is further configured to determine that the authentication for the content protection succeeds when a first message received from the external device is same as a second message generated by the wireless device,
wherein the first message is a message that is generated based on a public key of the external device, a public key of the wireless device, and a private key of the external device, and
wherein the second message is a message that is generated based on the public key of the external device, the public key of the wireless device, and a private key of the wireless device.

12. The wireless device of claim 8 , wherein the processor is further configured to determine that the transmission condition is satisfied when the external device supports a mirroring sink mode in which the external device receives and displays an image displayed by the external device, and authentication for content protection of the content image succeeds.

13. The wireless device of claim 8 , wherein the processor is configured to transmit the coordinate information to the external device through a User Input Back Channel (UIBC).

14. The wireless device of claim 8 , wherein the processor is further configured to provide the screen sharing service in any one connection mode of a first connection mode where the wireless device is connected with the external device through a router, or a second connection mode where the wireless device is directly connected with the external device without the router.
