Abstract
A display system is disclosed. The display system comprises a remote control device and a display device. The remote control device receives identification information about an external device from the external device, recognizes the angle of communication with the external device, and transmits the identification information and information about the angle to the display device. The display device identifies the external device on the basis of the information about the angle, and registers the identified external device as an operable external device when the remote control device is determined to have received the identification information while oriented toward the external device.
