Abstract

A method of controlling an external terminal from a terminal including receiving screen information from the external terminal; displaying the screen information as is displayed in the external terminal; selecting content information from the screen information, wherein the content information exists at recognized location; transmitting the location information of the selected content information to the external terminal; and receiving the selected content information corresponding to the transmitted location information from the external terminal. The location information includes coordinates information, which is relative coordinates of the selected content information.

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 input signal is received via an input device adapted to move a cursor and select content from the first screen information.

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

establishing communication with 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;

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

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

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

wherein the first data is related to contents displayed in the first device before receiving the location information from the second device,

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,

wherein the location information includes coordinate information,

wherein the coordinate information is relative coordinates of the selected content information in the first screen information reproduced on the screen of the second device,

wherein the establishing coomunication with the first device further comprises the second device receiving a communication request from the first device, and

wherein the establishing communication with the first device further comprises the second device receiving an authentication access request from the first device and the second device granting the authentication access request for sending and receiving information with the first device.

5. The method of claim 4, wherein the input signal is received via an input device adapted to move a cursor and select content from the first screen information.

6. 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 first data;

a display unit configured to reproduce first screen information based on the first data on a screen of the second 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 for executing a function based on the location information in the first device, and receive second data from the first device, wherein the second data is based on the executed function;
