Abstract

Provided are an apparatus for processing adaptive video and a method of scaling video, which generate a graphical user interface (GUI) so that a GUI suitable for the screen size of a display device can be displayed according to the screen size of the display device. The apparatus can realize a GUI most suitable for the screen size of an external display device connected to the apparatus by enlarging or reducing the size of the GUI according to the screen size of the external display device, or by changing the arrangement of items arranged on the GUI.

Claims

1. An apparatus for processing video, which provides video data by being connected to a display device, the apparatus comprising:

a display device information reader, which reads display device information that includes information about a screen size of the display device;

a graphical user interface (GUI) data storage unit, which stores data about a GUI displayed on the display device;

a GUI controller, which generates a control signal for changing at least one of a size and configuration of the GUI according to the screen size of the display device;

a GUI generator, which generates a GUI by changing the at least one of size and configuration of the GUI according to the control signal; and

a video processor, which combines and processes the generated GUI and an input video signal.

2. The apparatus of claim 1, wherein the display device information reader reads the information about a screen size of the display device by being connected to the display device using at least one of wired communication and wireless communication.

3. The apparatus of claim 1, wherein the display device information reader reads the information about a screen size of the display device from an external server connected through a network.

4. The apparatus of claim 1, wherein the GUI generator comprises:

a GUI generation information storage unit, which contains at least one of scaling ratio information of the GUI and configuration information of the GUI according to the screen size of the display device; and

a GUI changer, which changes the at least one of size and configuration of the GUI by using the at least one of scaling ratio information and configuration information.

5. The apparatus of claim 4, wherein the scaling ratio information is an enlargement ratio or reduction ratio of at least one of a horizontal and vertical component of the GUI based on the size of the GUI stored in the GUI data storage unit according to the screen size of the display device.

6. The apparatus of claim 4, wherein the configuration information includes arrangement information of items of the GUI displayed on one screen according to the screen size of the display device.

7. The apparatus of claim 1, wherein the GUI generator comprises:

a GUI scaling ratio calculator, which calculates a scaling ratio of the

GUI according to the screen size of the display device; and

a GUI changer, which changes the size of the GUI according to the calculated scaling ratio.

8. The apparatus of claim 1, wherein the display device information further comprises scaling ratio information of the GUI and configuration information of the GUI according to the screen size of the display device, and

the GUI generator changes the size and configuration of the GUI by respectively using the scaling ratio information and the configuration information included in the display device information.

9. The apparatus of claim 1, wherein the GUI controller controls the data about a GUI so as to be stored in the GUI data storage unit by receiving the data of a GUI suitable for a resolution of the display device from outside, according to the resolution of the display device.

10. The apparatus of claim 1, further comprising an input video scaler, which determines a video type of the input video signal and scales a predetermined portion of the input video signal according to a selection of a user or a requirement of a system.

11. A method of scaling video displayed on a predetermined display device, the method comprising:

reading display device information, which includes information about a screen size of the display device;

generating a GUI by changing at least one of a size and configuration of a GUI displayed on the display device according to the screen size of the display device; and

displaying the generated GUI on the display device after combining the generated GUI with an input video signal.

12. The method of claim 11, wherein the reading of the display device information comprises reading the information about the screen size of the display device by connecting to the display device using at least one of wired communication and wireless communication.

13. The method of claim 11, wherein the reading of the display device information comprises reading the information about the screen size of the display device from an external server connected through a network.

14. The method of claim 11, wherein the generating of the GUI comprises:

reading at least one of scaling ratio information of the GUI and configuration information of the GUI according to the pre-stored screen size of the display device; and

changing the at least one of size and configuration of the GUI by using the at least one of scaling ratio information and configuration information.

15. The method of claim 14, wherein the scaling ratio information is an enlargement ratio or reduction ratio of at least one of a horizontal and vertical component of the GUI based on the pre-stored size of the GUI according to the screen size of the display device.

16. The method of claim 14, wherein the configuration information contains arrangement information of items of the GUI displayed on one screen according to the screen size of the display device.

17. The method of claim 11, wherein the generating of the GUI comprises:

calculating a scaling ratio of the GUI according to the screen size of the display device; and

changing the size of the GUI according to the calculated scaling ratio.

18. The method of claim 11, wherein the display device information further comprises scaling ratio information of the GUI and configuration information of the GUI according to the screen size of the display device, and

the generating of the GUI changes the size and configuration of the GUI by respectively using the scaling ratio information and the configuration information contained in the display device information.

19. The method of claim 11, further comprising:

receiving and storing data of a GUI suitable for a resolution of the display device according to the resolution of the display device; and

generating the GUI by using the data stored according to the resolution of the display device.

20. The method of claim 11, further comprising:

determining a video type of the input video signal; and

scaling a predetermined portion of the input video signal according to a selection of a user or a requirement of a system.
