1. An apparatus for processing video, which provides video data by being connected to an external display device, the apparatus comprising:
- a screen, which displays the video data and has a horizontal length X and a vertical length Y;
a display device information reader, which reads display device information about a screen size of the external display device including a horizontal length X′ and
a vertical length Y′
;
a graphical user interface (GUI) data storage unit, which stores data about a GUI displayed on the external 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 external 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 scales the video data according to ratio of X;

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.
