Abstract

Disclosed is a method for providing multi-screen service of a mobile terminal, the method including requesting and obtaining information on a second display device if the mobile terminal is connected with a cradling stand; activating a predetermined wireless communication interface and searching for a peripheral device using a network manager so as to connect the mobile terminal with the peripheral device; if the multifunctional remote control device is found and is connected with the mobile terminal, managing linkage between the mobile terminal and the multifunctional remote control device using an interaction manager; and if a service request signal is received from the multifunctional remote control device for the mobile terminal, changing screen information of the mobile terminal in accordance with characteristics of the second display device using a display manager and displaying the changed screen information on a display unit of the second display device.

Claims

1. A system for providing a multi-screen service of a mobile terminal, the system comprising:

a mobile terminal;

a cradling stand for accepting the mobile terminal and for transmitting screen information from the mobile terminal to an external display device while the mobile terminal is accepted by the cradling stand and is communicably connected with the cradling stand, such that the screen information is displayed on the external display device; and

a remote control device for controlling the mobile terminal to transmit the screen information to the external display device through the cradling stand,

wherein the mobile terminal, the cradling stand, and the remote control device are separated from one another, and the mobile terminal can be used as a portable phone to make a phone call, and

wherein the screen information is directly transmitted from the mobile terminal to the external display device through the cradling stand, not through the remote control device.

2. The system as claimed in claim 1, wherein the screen information can be converted in accordance with a feature of a display screen of the external display device.

3. The system as claimed in claim 2, wherein the mobile terminal is equipped with a module supporting at least two types of wireless interfaces to perform communication.

4. The system as claimed in claim 1, wherein the mobile terminal changes a screen displayed on a display unit of the mobile terminal in accordance with characteristics of the external display device and transmits a signal corresponding to the changed screen to the external display device.

5. The system as claimed in claim 1, wherein the cradling stand charges the mobile terminal when the cradling stand is connected with the mobile terminal.

6. The system as claimed in claim 1, wherein the remote control device controls functions of the mobile terminal only when the mobile terminal is connected with the cradling stand.

7. The system as claimed in claim 1, further comprising an external device that is connected with the mobile terminal or the remote control device to provide various functions.

8. The system as claimed in claim 1, wherein the mobile terminal controls the cradling stand to transmit the screen information to the external display device.

9. A method for providing a multi-screen service of a mobile terminal, the method comprising:

communicably connecting a mobile terminal with a cradling stand, the mobile terminal being accepted by the cradling stand;

receiving an instruction from a remote control device to transmit screen information to an external display device; and

transmitting, based on the instruction, the screen information to the external display device through the cradling stand in order for the screen information to be displayed on the external display device,

wherein the mobile terminal, the cradling stand, and the remote control device are separated from one another, and

wherein the screen information is directly transmitted from the mobile terminal to the external display device through the cradling stand, not through the remote control device.

10. The method as claimed in claim 9, wherein the mobile terminal is equipped with a module using at least two types of wireless interfaces to perform communication.

11. The method as claimed in claim 9, further comprising:

changing a screen displayed on a display unit of the mobile terminal in accordance with characteristics of the external display device; and

transmitting a signal corresponding to the changed screen to the external display device.

12. The method as claimed in claim 9, wherein the cradling stand charges the mobile terminal when the cradling stand is connected with the mobile terminal.

13. The method as claimed in claim 9, wherein the remote control device controls functions of the mobile terminal only when the mobile terminal is connected with the cradling stand.

14. The method as claimed in claim 9, wherein the mobile terminal or the remote control device is connected with an external device to provide various functions of the external device.

15. The method as claimed in claim 9, wherein transmitting the screen information to the external display device through the cradling stand comprises:

transmitting, by the mobile terminal, the screen information to the cradling stand; and

transmitting, by the cradling stand, the screen information to the external display device.
