Abstract

A method and an apparatus for sharing a screen with a counterpart electronic device in an electronic device are provided. In the method, connection with at least one counterpart electronic device is performed. Data to display on the electronic device or data to transmit to the counterpart electronic device are determined. Data is transmitted to the counterpart electronic device. Data transmission to the counterpart electronic device is stopped based on state information of the electronic device or the counterpart electronic device.

First claim

What is claimed is:

1. A method in a first electronic device, the method comprising:
connecting with at least one second electronic device;
determining data to transmit to the at least one second electronic device;
transmitting the data to the at least one second electronic device; and
stopping transmission of the data based on state information of the at least one second electronic device while maintaining the connection with the at least one second electronic device,
wherein the state information includes a display state of the data displayed in the at least one second electronic device.

2. The method of claim 1 , wherein connecting with the at least one second electronic device comprises:
connecting with the second electronic device using a wireless communication scheme or a wired communication scheme,
wherein the wired communication scheme comprises one of a Universal Serial Bus (USB), a High Definition Multimedia Interface (HDMI), an Mobile High-Definition Link (MHL), and a display port, and the wireless communication scheme comprises cellular communication or a short distance wireless communication scheme.

3. The method of claim 2 , wherein the short distance wireless communication scheme comprises one of Bluetooth, Zigbee, Wireless Fidelity (WiFi), WiFi direct, and Near Field Communication (NFC).

4. The method of claim 1 , wherein determining the data to transmit to the second electronic device comprises:
determining a storage space for storing the data; and
determining the data to store in the storage space.

5. The method of claim 1 , wherein stopping the transmission of the data comprises maintaining the connection with the at least one second electronic device.

6. The method of claim 1 , wherein stopping the transmission of the data comprises, when a request for stopping data transmission occurs in the at least one second electronic device, stopping the transmission of the data.

7. The method of claim 1 , further comprising, when an event occurs in the first electronic device, stopping the transmission of the data.

8. The method of claim 7 , wherein the event comprises at least one of a touch input, a button input, an electronic pen input, call reception, message reception, and a notification.

9. The method of claim 7 , further comprising, when the transmission of the data is stopped, resuming the stopped transmission of the data based on the state information or whether the event occurs.

10. The method of claim 1 , wherein stopping the transmission of the data comprises stopping encoding of the data.

11. A method in a second electronic device, the method comprising:
connecting with at least one first electronic device;
receiving data from the at least one first electronic device;
displaying the received data;
determining whether an event for stopping displaying the data occurs based on state information of the second electronic device; and
in response to the occurrence of the event for stopping displaying the data, transmitting a request signal for stopping data transmission to the at least one first electronic device, while maintaining the connection with the at least one first electronic device,
wherein the state information includes a display state of the data displayed in the at least one second electronic device.

12. The method of claim 11 , further comprising, when at least one state change of an idle mode, power off, rebooting, and screen turn-off occurs, transmitting the request signal for stopping the data transmission.

13. The method of claim 11 , wherein the request signal for stopping the data transmission comprises:
when a region of a screen of the second electronic device displaying the data is hidden, transmitting the request signal for stopping the data transmission, and
wherein a case where the region displaying the data is hidden by the specific portion or more comprises a case where the displaying of the data is minimized or a display layer of an upper level than the region displaying the data is generated depending on driving of an application in the electronic device.

14. A first electronic device comprising:
at least one display;
at least one memory configured to store shared data with at least one second electronic device; and
at least one processor configured to:
perform a connection with the at least one second electronic device,
determine data to transmit to the second electronic device,
transmit the data to the second electronic device, and
stop transmission of the based on state information of the at least one second electronic device while maintaining the connection with the counterpart at least one second electronic device,
wherein the state information includes a display state of the data displayed in the at least one second electronic device.

15. The electronic device of claim 14 , wherein the at least one processor is configured to perform the connection with the at least one second electronic device using a wireless communication scheme or a wired communication scheme, and
wherein the wired communication scheme comprises one of a USB, an HDMI, an MHL, and a display port, and the wireless communication scheme comprises cellular communication or a short distance wireless communication scheme.

16. The electronic device of claim 14 , wherein the at least one processor is configured to:
determine a storage space for storing the data, and
determine the data to store in the storage space.

17. The electronic device of claim 14 , wherein the at least one processor is configured to maintain the connection with the at least one second electronic device when transmission of the data is stopped.

18. The electronic device of claim 14 , wherein the at least one processor is configured to stop transmission of the data, when a request for stopping data transmission is received from the at least one second electronic device.

19. The electronic device of claim 14 , wherein the at least one processor is configured to stop the transmission of the data when an event occurs in the electronic device.

20. The electronic device of claim 19 , wherein the event comprises at least one of a touch input, a button input, an electronic pen input, call reception, message reception, and a notification.

21. The electronic device of claim 14 , wherein the at least one processor is configured to resume the stopped transmission of the data based on state information of the electronic device or the at least one second electronic device when the transmission of the data is stopped.

22. The electronic device of claim 14 , wherein the at least one processor is configured to stops encoding of the data to transmit to the at least one second electronic device when the transmission of the data is stopped.

23. A second electronic device comprising:
at least one display;
at least one memory configured to store shared data with at least one first electronic device; and
at least one processor configured to:
perform a connection with the at least one first electronic device,
receive data from the at least one first electronic device,
display the received data on the display,
determine whether an event for stopping displaying the data occurs based on state information of the second electronic device, and
in response to the occurrence of the event for stopping the displaying of data, transmitting a request signal for stopping data transmission to the at least one first electronic device while maintaining the connect
