摘要： The present disclosure relates to an image display device and a method of operating the same. The image display device according to an embodiment of the present disclosure includes: a display configured to display a pointer corresponding to a remote controller; an external device interface including at least one communication module and configured to perform short-range communication; and a controller, wherein the controller: receives, from the remote controller, an input signal including movement data of the remote controller through the external device interface; monitors a connection status with the remote controller based on the received input signal; if the connection status is good, calculates coordinates of the pointer based on the movement data included in the input signal; if the connection status is bad, processes the movement data included in the input signal, and then calculates coordinates of the pointer based on the processed data; and displays the pointer on the display based on the calculated coordinates of the pointer. Various other embodiments are also possible.

摘要： The present disclosure relates to a remote control device and an image display apparatus including the same. A remote control device according to an embodiment of the present disclosure includes: a plurality of keys; an IR module configured to perform IR communication in response to a part of the plurality of keys; and an RF module configured to perform RF communication in response to another part of the plurality of keys, and the RF module transmits wireless channel information to an image display apparatus at a first interval, and when pairing with the image display apparatus is not completed, transmits the wireless channel information at a second interval less than the first interval. As a result, wireless pairing can be stably performed in response to a surrounding communication environment.
