Abstract

A method for providing a multi-screen service is provided. The method includes transmitting, by a remote control device, a control signal to a cradling stand, receiving, by a mobile phone, the control signal from the remote control device via the cradling stand, and in response to the control signal, transmitting screen information to an external display device via the cradling stand, wherein the mobile phone is to transmit call information to the external display device via the cradling stand if a call is received.

Claims

1. A method for providing a multi-screen service, the method comprising:

transmitting, by a remote control device, a control signal to a cradling stand; and

receiving, by a mobile phone, the control signal from the remote control device via the cradling stand, and in response to the control signal, transmitting screen information to an external display device via the cradling stand,

wherein the mobile phone transmits call information to the external display device via the cradling stand if a call is received by the mobile phone.

2. The method of claim 1, further comprising automatically returning, by the mobile phone, to a state of the mobile phone at the time the mobile phone is not communicably connected with the cradling stand, if the mobile phone is separated from the cradling stand.

3. The method of claim 1, wherein the mobile phone controls to input content desired by a user by using a pointing device including at least one of a keyboard and a mouse,

wherein the keyboard is at least one of a wired and a wireless keyboard.

4. The method of claim 1, wherein, when the mobile phone is communicably connected to the external display device via the cradling stand, a display unit of the mobile phone is turned off for saving power and the external display device is used to display the screen information.

5. The method of claim 1, wherein the cradling stand connects the mobile phone to the external display device, and

wherein the cradling stand charges a battery of the mobile phone.

6. The method of claim 1, wherein the call received by the mobile phone is a video call.

7. A system for providing a multi-screen function, the system comprising:

a cradling stand;

a remote control device to transmit a control signal to the cradling stand; and

a mobile phone to receive the control signal from the remote control device via the cradling stand, and in response to the control signal, to transmit screen information to an external display device via the cradling stand,

wherein the mobile phone transmits call information to the external display device via the cradling stand if a call is received by the mobile phone.

8. The system of claim 7, wherein the mobile phone automatically returns to a state of the mobile phone at the time the mobile phone is not communicably connected with the cradling stand, if the mobile phone is separated from the cradling stand.

9. The system of claim 7, wherein the mobile phone comprises an input unit receiving input content, desired by a user, from a pointing device including at least one of a keyboard and a mouse,

wherein the keyboard is at least one of a wired and a wireless keyboard.

10. The system of claim 7, wherein, when the mobile phone is communicably connected to the external display device via the cradling stand, a display unit of the mobile phone is turned off for saving power and the external display device is used to display the screen information.

11. The system of claim 7, wherein the mobile phone is connected to the external display device via the cradling stand, and

wherein a battery of the mobile phone is charged by the cradling stand.

12. The system of claim 7, wherein the call received by the mobile phone is a video call.
