Abstract

A mobile terminal including a display unit outputting an image, a communication unit transceiving data with an external mobile terminal, and a controller controlling the communication unit to receive a screen information of the mobile terminal and a 1^st control information of the screen information from the mobile terminal and to transmit a 2^nd control information of the screen information to the mobile terminal, the controller controlling the display unit to transform the 1^st control information of the screen information and to output the transformed screen information to a user. The 1^st control information includes an image size transformation information of the screen information and an image compression format information of the screen information. The 2^nd control information includes a supportable compression format information.

Claims

1. An image display device mounted on a vehicle, comprising:

a display unit configured to output an image;

a communication unit configured to transceive data with an external mobile terminal; and

a controller configured to control the communication unit to receive a screen information of the mobile terminal and a 1^st control information of the screen information from the mobile terminal, the controller configured to control the communication unit to transmit a 2^nd control information of the screen information to the mobile terminal, the controller configured to control the display unit to transform the 1^st control information of the screen information, the controller configured to control the display unit to output the transformed screen information to a user,

wherein the 1^st control information comprises an image size transformation information of the screen information and an image compression format information of the screen information and

wherein the 2^nd control information comprises a supportable compression format information.

2. The image display device of claim 1, wherein the 2^nd control information further comprises an information indicating whether the screen information is a transformed screen.

3. The image display device of claim 1, wherein the 2^nd control information further comprises a supportable encoding type information and.

4. The image display device of claim 1, wherein the 2^nd control information further comprises an information of a 1^st frame buffer included in the image display device mounted on the vehicle.

5. The image display device of claim 1, wherein the image size transformation information comprises a multiple information of an image size of the screen information.

6. The image display device of claim 1, wherein the controller receives the screen information generated from a 2^nd frame buffer included in the mobile terminal.

7. The image display device of claim 6, wherein the 2^nd control information comprises an information for requesting the 2^nd frame buffer to update the screen information.

8. The image display device of claim 6, wherein the 1^st control information comprises an information for notifying the 2^nd frame buffer that the screen information has been updated and an information of the updated 2^nd frame buffer.

9. A mobile terminal comprising:

a communication unit configured to transceive data with an external image display device; and

a controller configured to control the communication unit to transmit a screen information of the mobile terminal and a 1^st control information of the screen information to the image display device, the controller configured to control the communication unit to receive a 2^nd control information of the screen information from the image display device, the controller configured to generate the screen information in accordance with the 1^st control information,

wherein the 1^st control information comprises an image size transformation information of the screen information and an image compression format information of the screen information and

wherein the 2^nd control information comprises a supportable compression format information supportable by the image display device.

10. The mobile terminal of claim 9, wherein the 2^nd control information further comprises an information indicating whether the screen information is a transformed screen.

11. The mobile terminal of claim 9, wherein the 2^nd control information further comprises an encoding type information supportable by the image display device and an information of a 1^st frame buffer included in the image display device mounted on the vehicle.

12. The mobile terminal of claim 9, wherein the image size transformation information comprises a multiple information of an image size of the screen information.

13. The mobile terminal of claim 9, wherein the controller generates the screen information from a 2^nd frame buffer included in the mobile terminal.

14. The mobile terminal of claim 13, wherein the 2^nd control information comprises an information for requesting the 2^nd frame buffer to update the screen information.

15. The mobile terminal of claim 13, wherein the 1^st control information comprises an information for notifying the 2^nd frame buffer that the screen information has been updated and an information of the updated 2^nd frame buffer.
