The display controller 110 controls the entire system and can control each of the plurality of display devices 100 under the control of the soft joystick 200 in conjunction with the soft joystick 200.

The soft joystick 200 can control various kinds of functions supported by the display device by interlocking with the display control device 110. In particular, the soft joystick 200 may include a plurality of preset function blocks on the screen, and may control various types of functions supported by the display system based on the plurality of function blocks.

For example, in the case of a camera image, such a function block may move the camera to a desired angle or adjust the magnification through PTZ (= Pan / Tilt / Zoom. Pan / tilt / zoom) control, In order to show it, the screen is divided into several virtual images to display multiple camera images at the same time. This virtual division is called a layout and can be expressed in various forms such as 1, 4, 9, 16 characters according to the number of divided images. In this case, playback, pause, fast forward (FF), rewind (Rew), arbitrary movement (Seek) with VOD in a specific time zone, .

At this time, the function block is a block for controlling the function of the display system, and may be set in advance by the user, and may be changed, i.e., added or deleted, as needed.
