Abstract
A television set carries out communications with a remote control. When the television set displays a picture based on a picture signal subjected to quality adjustment, a signal level of a quality adjustment parameter is obtained, and the data indicating the obtained signal level is transmitted to the remote control. The remote control displays the received data. The user checks the displayed data, and enters data for changing the signal level so that the remote control transmits the entered data to the television set. The television set receives the changed level data, and adjusts the quality relating to the picture signal based on the received level data. The television set displays the picture of the quality adjusted according to the signal level changed by the user.
