Abstract

The present invention discloses a system and a method used for outputting a plurality of operating system screens to a single monitor in a virtual terminal at the same time and used for controlling a virtual screen. According to an embodiment of the present invention, the system used for controlling the virtual screen comprises: an operating system unit comprising at least one operating system, wherein, the operating system is configured to generate data to be output to a display device in a frame buffer; and a virtual machine monitor configured to divide the screen into preset windows assigned to the operating systems, converting the data in the frame buffer into the windows, and outputting the virtual screen to the operating systems at the same time. Therefore, by displaying the plurality of operating systems on the display device at the same time, it is possible to allow that contents of application programs executed in the plurality of operating systems can be checked at the same time through the display device.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2010-0134083 filed in the Korean Intellectual Property Office on December 23, 2010, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a system for controlling a virtualized screen, and more particularly, to a system for controlling the simultaneous output of multiple operating system screens to a single display device in a virtualized terminal. Systems and methods for screens. Background technique [0004] In the related art, when a virtualization technology is applied to a terminal device having a display device, one operating system exclusively uses the display device at a certain timing. While the one operating system is using the display device exclusively, if the user wishes to see a screen for the other operating system, the screen for the other operating s...
