output a first group of keys corresponding to the remote control mode through the display unit, and
output a second group of keys corresponding to the keyboard mode in response to a keyboard mode activation signal received from the display device,
wherein when outputting the second group of keys corresponding to the keyboard mode, keys and dividing lines included in the second group of keys are disposed in orthogonal direction between the keys included in the first group of keys so as not to overlap with the keys included in the first group of keys,
a key included in the second group of keys is located in a diagonal direction with a key included in the first group of keys, and
the dividing line included in the second group of keys is aligned with the key included in the first group of keys.
