    Abstract: The present disclosure relates to an image display apparatus and a method thereof. The image display apparatus according to an embodiment of the present disclosure comprises: a display; an external device interface including at least one communication module, the external device being configured to communicate with a remote control device using short-range communication; a memory; and a controller configured to: check a voltage value of a battery included in the remote control device based on data included in a control signal received from the remote control device; when the voltage value of the battery is less than a predetermined reference voltage value, store the voltage value of the battery in the memory, and output a first message for requesting battery replacement through the display; when the control signal includes data indicating that the battery is replaced, calculate a voltage difference between a voltage value stored in the memory and the voltage value included in the control signal; and when the voltage difference is less than a predetermined reference difference, determine that the replaced battery needs to be replaced.

    Abstract: 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.
