Abstract

A method of sharing a screen of a first device with a second device and a device using the same are provided. The method includes transmitting information on a first screen displayed on the first device to the second device, in a first connection state so that a same screen is displayed by the first device and the second device; switching the first connection state between the first device and the second device into a second connection state; and performing a control so that the first screen displayed on the first device is switched into a second screen so that the first screen displayed is continuously displayed on the second device, when a user input is received in a state in which the first connection state is switched into the second connection state in which an independent screen is displayed by the first device and the second device.

Claims

1. A method of sharing a screen of a first device with a second device by the first device, the method comprising:

transmitting video content displayed on the first device to the second device while the first device and the second device are connected in a first connection state, in which content displayed on the first device is displayed on the second device;

based on a user input selecting a user interface (UI) element displayed on the first device, switching from the first connection state to a second connection state, in which content independent of the content displayed on the first device is displayed on the second device; and

while the first device and the second device are connected in the second connection state, displaying content different than the video content on the first device and continuously transmitting the video content to the second device so that the video content is continuously displayed on the second device.

2. The method as claimed in claim 1, wherein switching the first connection state between the first device and the second device into the second connection state includes switching the first connection state between the first device and the second device into the second connection state in response to the user input selecting the UI element included in a pop-up screen which is independent of the video content displayed on the first device.

3. The method as claimed in claim 2, wherein the pop-up screen includes notification information indicating synchronization or desynchronization between screens of the first device and the second device.

4. The method as claimed in claim 2, wherein when the first device shares the video content with a group of second devices, the pop-up screen includes at least one of a number of second devices in the group of second devices, identification information of the group of second devices, and identification information of the second devices in the group of second devices.

5. The method as claimed in claim 1, wherein switching the first connection state between the first device and the second device into the second connection state includes stopping a synchronization mode in which the same screen is displayed by the first device and the second device and executing a desynchronization mode in which independent screens are displayed by the first device and the second device.

6. The method as claimed in claim 1, wherein transmitting the video content displayed on the first device to the second device includes compressing the video content and transmitting the compressed video content to the second device.

7. The method as claimed in claim 1, wherein transmitting the video content displayed on the first device to the second device includes compressing image contents included in the video content displayed on the first device and transmitting the compressed image contents to the second device.

8. The method as claimed in claim 1, further comprising:

receiving information on the user input through the second device from the second device; and

transmitting information related to the user input to the second device, in response to the information on the user input.

9. The method as claimed in claim 1, further comprising, before transmitting the video content displayed on the first device to the second device,

displaying icons representative of each of a plurality of second devices which communicate with the first device;

and

when one of the displayed icons is selected, connecting the first device to one of the plurality of second devices corresponding to the selected icon in the first connection state.

10. The method as claimed in claim 1, wherein the user input is a floating input which is not in contact with a display of the first device.

11. A first device for sharing video content with a second device, the first device comprising:

a touch screen configured to sense a user input, and display the video content on the first device;

a communicator configured to transmit the displayed video content on the first device to the second device while the first device and the second device are connected in a first connection state, in which content displayed on the first device is displayed on the second device; and

a processor configured to;

based on a user input selecting a user interface (UI) element displayed on the first device, switch from the first connection state to a second connection state, in which content independent of content displayed on the first device is displayed on the second device, and

while the first device and the second device are connected in the second connection state, displaying content different than the video content on the first device, and continuously transmit the video content to the second device so that the video content is continuously displayed on the second device.

12. The first device as claimed in claim 11, wherein the touch screen is further configured to sense the user input selecting a UI element included in a pop-up screen which is independent of the video content displayed on the first device, in order to switch from the first connection state to the second connection state.

13. The first device as claimed in claim 12, wherein the pop-up screen includes notification information indicating synchronization or desynchronization between screens of the first device and the second device.

14. The first device as claimed in claim 12, wherein when the first device shares the video content with a group of second devices, the pop-up screen includes at least one of a number of second devices in the group of second devices, identification information of the group of second devices, and identification information of the second devices in the group of second devices.

15. The first device as claimed in claim 11, wherein when the first connection state is switched to the second connection state,

the processor is further configured to stop a synchronization mode in which the same screen is displayed by the first device and the second device, and execute a desynchronization mode in which independent screens are displayed by the first device and the second device.

16. The first device as claimed in claim 11, wherein when the communicator transmits the video content displayed on the first device to the second device, the communicator is further configured to compress the video content and transmit the compressed video content to the second device.

17. The first device as claimed in claim 11, wherein when the communicator transmits the video content displayed on the first device to the second device, the communicator is further configured to compress image contents included in the video content and transmit the compressed image contents to the second device.

18. The first device as claimed in claim 11, wherein the communicator is further configured to receive information on the user input from the second device, and transmit information related to the user input to the second device.

19. The first device as claimed in claim 11, wherein the touch screen is further configured to display icons representative of each of a plurality of second devices which communicate with the first device, and

wherein the processor is further configured to connect the first device to one of the plurality of second devices corresponding to a selected icon in the first connection state, when a user input selecting one of the displayed icons is received through the touch screen.

20. The first device as claimed in claim 11, wherein the user input is a floating input which is not in contact with a display of the first device.
