control a display state of a pointer of the remote control device and a display state of a cursor of the external device based on a set pointer display mode among a plurality of pointer display modes,
wherein the pointer display mode for controlling the display state of the pointer of the remote control device and the display state for the cursor of the external device is set based on an indicator included in the control data received from the external device, wherein the indicator indicates whether the external device is able to be controlled by the remote control device.
2. The display device according to claim 1 , wherein the controller is configured to control the display to operate in the set pointer display mode in which the pointer of the remote control device is transparently displayed based on the control data indicating that the external device is able be controlled by the remote control device.
3. The display device according to claim 1 , wherein the controller is configured to control the display to operate in the set pointer display mode in which the pointer of the remote control device is transparently displayed based on the cursor of the external device being included in the displayed external device screen and the external device being able to be controlled by the remote control device.
4. The display device according to claim 1 , wherein a shape of the pointer of the remote control device is displayed differently based on whether the external device is able to be controlled by the remote control device.
5. The display device according to claim 1 , wherein a display transparency of the pointer of the remote control device is higher based on the external device being able to be controlled by the remote control device than when the external device is not able to be controlled by the remote control device.
6. The display device according to claim 1 , wherein the pointer display mode is changed according to a position of the pointer of the remote control device.
7. The display device according to claim 6 , wherein the controller is configured to control the display to operate in the set pointer display mode in which the pointer of the remote control device is transparently displayed based on the pointer being located on the displayed external device screen.
8. The display device according to claim 7 , wherein the pointer of the remote control device is displayed with higher transparency when the pointer is located on the displayed external device screen than when the pointer is located outside of the displayed external device screen.
9. The display device according to claim 6 , wherein the plurality of pointer display modes comprise:
a first mode when the pointer is located outside of the displayed external device screen;
a second mode when the pointer is located on the displayed external device screen and the external device is able to be controlled by the remote control device; and
a third mode when the pointer is located on the displayed external device screen and the external device is not able to be controlled by the remote control device.
10. A method of operating a display device, the method comprising:
receiving control data and image data from an external device;
displaying an external device screen based on the received image data, wherein the displayed external device screen is the same as a screen being displayed on the external device; and
controlling a display state of a pointer to of the remote control device and a display state of a cursor of the external device based on a set pointer display mode among a plurality of pointer display modes,
wherein the pointer display mode for controlling the display state of the pointer of the remote control device and the display state for the cursor of the external device is set based on an indicator included in the control data received from the externally device, wherein the indicator indicates whether the external device is able to be controlled by the remote control device.
11. The method of claim 10 , further comprising:
performing control to operate in the set pointer display mode in which the pointer of the remote control device is transparently displayed based on the control data indicating that the external device is able be controlled by the remote control device.
12. The method of claim 10 , further comprising:
performing control to operate in the set pointer display mode in which the pointer of the remote control device is transparently displayed based on the cursor of the external device being included in the displayed external device screen and the external device being able to be controlled by using the remote control device.
13. The method of claim 10 , wherein:
a shape of the pointer of the remote control device is displayed differently based on whether the external device is able to be controlled by the remote control device.
14. The method of claim 10 , wherein:
a display transparency of the pointer of the remote control device is higher based on the external device being able to be controlled by the remote control device than when the external device is not able to be controlled by the remote control device.
15. The method of claim 10 , wherein the pointer display mode is changed according to a position of the pointer of the remote control device.
16. The method of claim 15 , further comprising:
performing control to operate in the set pointer display mode in which the pointer of the remote control device is transparently displayed based on the pointer being located on the displayed external device screen.
17. The method of claim 16 , wherein the pointer of the remote control device is displayed with higher transparency when the pointer is located on the displayed external device screen than when the pointer is located outside of the displayed external device screen.
18. The method of claim 15 , wherein plurality of pointer display modes comprise:
a first mode when the pointer is located outside of the displayed external device screen;
a second mode when the pointer is located on the displayed external device screen and the external device is able to be controlled by the remote control device; and
a third mode when the pointer is located on the displayed external device screen and the external device is not able to be controlled by the remote control device.
