Abstract: When display switching is instructed in a state that a program schedule according to time is displayed, in which a time axis is set in a horizontal direction and a channel axis is set in a vertical direction, respectively, a program schedule according to channels is displayed in which the time axis is set in the horizontal direction and the channel axis is set in the vertical direction, respectively. In the program schedule, a wider area than other channels is assigned to the channel which has been focused in the program schedule according to time, and information of programs broadcasted by the channel are displayed at positions corresponding to broadcast time of the programs, respectively. The invention can be applied to equipment capable of displaying an EPG, such as a digital television receiver, a hard disk recorder, or a DVD recorder.
