Abstract

A method of controlling a first device and a second device, and which includes transmitting first data from the first device to the second device, receiving the first data by the second device, reproducing first screen information based on the first data on a screen of the second device, receiving, in the second device, an input signal for selecting content information in the first screen information reproduced on the screen of the second device, transmitting location information corresponding to the selected content information from the second device to the first device, receiving the location information and executing a function based on the location information in the first device, transmitting second data from the first device to the second device, in which the second data is based on the executed function; and reproducing second screen information based on the second data on the screen of the second device. Further, the location information includes coordinate information of the selected content information in the first screen information reproduced on the screen of the second device.

Claims

1. A method of controlling a first device and a second device, the method comprising:

establishing communication between the first device and the second device, wherein the first device searches for devices to be connected and when devices including the second device are found, the first device transmits an access authentication request to the second device and the second device accepts the access authentication request by the first device;

transmitting first data from the first device to the second device;

receiving the first data by the second device;

reproducing first screen information based on the first data on a screen of the second device, wherein the first screen information includes a virtual manipulation unit corresponding to a manipulation unit provided at a main body of the first device;

receiving, in the second device, an input signal for selecting content information in the first screen information reproduced on the screen of the second device;

transmitting location information corresponding to the selected content information from the second device to the first device;

receiving the location information and executing a function based on the location information in the first device;

transmitting second data from the first device to the second device, wherein the second data is based on the executed function; and

reproducing second screen information based on the second data on the screen of the second device,

wherein the location information includes coordinate information of the selected content information in the first screen information reproduced on the screen of the second device.

2. The method of claim 1, wherein the first device is a mobile device capable of wirelessly communicating with other display devices.

3. The method of claim 1, wherein the first data is related to contents displayed in the first device before receiving the location information from the second device.

4. The method of claim 3, wherein the second data is related to contents displayed in the first device after receiving the location information from the second device and executing the function based on the location information from the second device.

5. The method of claim 1, wherein while the first device displays contents, the second device reproduces screen information based on data received from the first device related to the contents displayed in the first device.

6. The method of claim 1, wherein the input signal is received via an input device adapted to move a cursor and select content from the first screen information.

7. A method of controlling a first device from a second device, the method comprising:

establishing communication with the first device, wherein the second device receives an access authentication request from the first device and the second device accepts the access authentication request by the first device;

receiving first data from the first device;

reproducing first screen information based on the first data on a screen of the second device, wherein the first screen information includes a virtual manipulation unit corresponding to a manipulation unit provided at a main body of the first device;

receiving an input signal for selecting content information in the first screen information reproduced on the screen of the second device;

transmitting location information corresponding to the selected content information to the first device; and

reproducing second screen information based on second data received from the first device on the screen of the second device,

wherein the location information includes coordinate information of the selected content information in the first screen information reproduced on the screen of the second device.

8. The method of claim 7, wherein the first data is related to contents displayed in the first device before receiving the location information from the second device.

9. The method of claim 8, wherein the second data is related to contents displayed in the first device after receiving the location information from the second device and executing the function based on the received location information from the second device.

10. The method of claim 7, wherein while the first device displays contents, the second device reproduces screen information based on data received from the first device related to the contents displayed in the first device.

11. The method of claim 7, wherein the input signal is received via an input device adapted to move a cursor and select content from the first screen information.

12. A second device comprising:

a wireless communication unit configured to establish communication with a first device, wherein the wireless communication unit is further configured to receive an access authentication request from the first device and first data from the wirelessly communicated first device;

a display unit configured to display first screen information based on the first data on a screen of the second device after accepting the access authentication request from the first device, wherein the first screen information includes a virtual manipulation unit corresponding to a manipulation unit provided at a main body of the first device; and

a control unit configured to receive an input signal for selecting content information and transmit location information corresponding to the selected content information to the first device,

wherein the display unit further displays second screen information based on second data on the screen of the second device, wherein the second data corresponds to screen information of an executed function in the first device based on the transmitted location information from the second device, and

wherein the location information includes coordinate information of the selected content information in the first screen information reproduced on the screen of the second device.

13. The second device of claim 12, wherein the wireless communication unit is further configured to establish communication with the first device and to transceive data with the first device.

14. The second device of claim 12, wherein the input signal is received via an input device configured to move a cursor and select content from first screen information.

15. The second device of claim 12, wherein while the first device displays contents, the second device reproduces screen information based on data received from the first device related to the contents displayed in the first device.

21. The second device of claim 12, wherein the display unit displays the first screen information overlapped with screen information already displayed in the display unit of the second device.

22. The second device of claim 12, wherein the virtual manipulation unit corresponds to a manipulation unit of the main body of the first device as configured in the first device.

23. The second device of claim 22, wherein the virtual manipulation unit includes at least one of a shape of a menu key, a call key, a direction key, or a keypad for manipulating the first device.

24. The second device of claim 22, wherein the virtual manipulation unit changes depending upon a model of the first device.

16. A first device comprising:

a wireless communication unit configured to establish communication with a second device, wherein the wireless communication unit is further configured to transmit first data to the wirelessly communicated second device, wherein the first device searches for devices to be connected and when devices including the second device are found, the first device transmits an access authentication request to the second device and receives acceptance of the access authentication request from the second device;

a display unit configured to display contents on a screen of the first device; and
