The control unit may respectively allocate a plurality of buttons included in the remote control device to the plurality of source devices, receive a signal corresponding to an input of a first button of the plurality of allocated buttons as the control activation request for the first source device from the remote control device, and activate control of the first source device in response to the received signal.
The control unit may control the display unit to display an icon of each of the plurality of allocated buttons on content of a corresponding source device from among the plurality of pieces of content displayed through the display unit.
Default control commands respectively corresponding to plurality of allocated buttons may be deactivated during display of the plurality of pieces of content received from the plurality of source devices.
The control unit may display a pointer corresponding to movement of the remote control device, move a display position of the pointer based on information on the movement received from the remote control device, and activate control of a source device which provides content displayed at the position of the pointer.
The control unit may control the display unit to display a control activation icon indicating that control of the first source device is activated on content received from the first source device and displayed.
The control unit may determine a control command for the signal received from the remote control device and transmit the determined control command to the first source device, and the control command for the signal may be changed depending on a type of the first source device.
The control unit may respectively allocate one or more numbers to one or more menus included in the content received from the first source device of which control is activated, and control the display unit to respectively display the one or more allocated numbers on the corresponding menus.
The control unit may receive a signal corresponding to input of a specific number button from the remote control device, and transmit a command for selecting a menu allocated a number corresponding to the input of the specific number button based on the received signal.
The control unit may display a screen for selecting a source device which is to display content, receive a selection request for selecting the plurality of source devices based on the displayed screen, and receive the plurality of pieces of content from the plurality of source devices in response to the received selection request.
In another embodiment, a method of operating a display device, the method includes displaying a plurality of pieces of content received from a plurality of source devices connected to the display device; receiving a control activation request for a first source device of the plurality of source devices from a remote control device; activating control of the first source device in response to the received control activation request; and controlling an operation of the first source device in response to the signal received from the remote control device.

Again,
If the user input unit 230 includes a touch screen, a user can touch a soft key of the touch screen to input a command relating to the display device 100 to the remote control device 200. Additionally, the user input unit 230 can include various kinds of input means manipulated by a user, for example, a scroll key and a jog key, and this embodiment does not limit the scope of the present invention.
The sensor unit 240 can include a gyro sensor 241 or an acceleration sensor 243 and the gyro sensor 241 can sense information on a movement of the remote control device 200.
For example, the gyro sensor 241 can sense information on an operation of the remote control device 200 on the basis of x, y, and z axes and the acceleration sensor 243 can sense information on a movement speed of the remote control device 200. Moreover, the remote control device 200 can further include a distance measurement sensor and sense a distance with respect to the display unit 180 of the display device 100.

Then,
A user can move or rotate the remote control device 200 vertically or horizontally. The pointer 205 displayed on the display unit 180 of the display device 100 corresponds to a movement of the remote control device 200. Since the corresponding pointer 205 is moved and displayed according to a movement on a 3D space as show in the drawing, the remote control device 200 can be referred to as a spatial remote controller.
Information on a movement of the remote control device 200 detected through a sensor of the remote control device 200 is transmitted to the display device 100. The display device 100 can calculate the coordinates of the pointer 205 from the information on the movement of the remote control device 200. The display device 100 can display the pointer 205 to match the calculated coordinates.
On the other hand, if a user moves the remote control device 200 close to the display unit 180, a selection area in the display unit 180 corresponding to the pointer 205 can be zoomed out and displayed reduced.
On the other hand, if the remote control device 200 is away from the display unit 180, a selection area can be zoomed out and if the remote control device 200 is close to the display unit 180, a selection area can be zoomed in.

That is, if the remote control device 200 is moved away from or close to the display unit 180, the up, down, left, or right movement cannot be recognized and only the back and forth movement can be recognized. While a specific button in the remote control device 200 is not pressed, only the pointer 205 is moved according to the up, down, left or right movement of the remote control device 200.
Moreover, the moving speed or moving direction of the pointer 205 can correspond to the moving speed or moving direction of the remote control device 200.
Furthermore, a pointer in this specification means an object displayed on the display unit 180 in correspondence to an operation of the remote control device 200. Accordingly, besides an arrow form displayed as the pointer 205 in the drawing, various forms of objects are possible. For example, the above concept includes a point, a cursor, a prompt, and a thick outline. Then, the pointer 205 can be displayed in correspondence to one point of a horizontal axis and a vertical axis on the display unit 180 and also can be displayed in correspondence to a plurality of points such as a line and a surface.
