The display device includes a touch detection sensor, a wireless communication section, a display controller, and a touch panel controller. The touch detection sensor detects a touch on the screen. The wireless communication section receives signals from the plurality of electronic pens connected. The display controller determines a distance between at least two electronic pens out of the plurality of electronic pens connected, from the signals received via the wireless communication section. The touch panel controller enables or disables a function of the touch detection sensor based on the above determination.

A digital broadcast receiver includes an operation mode manager that switches an operation mode to a first mode in which a function is implemented by the downloaded application or a second mode in which a function is implemented by the pre-installed application, and a key delivery module that delivers the key code received from the remote control to the downloaded application or the pre-installed application. When the receiver is in the first mode, the key delivery module delivers the received key code to the downloaded application if the received key code is a key code for the first mode, and delivers the received key code to the pre-installed application if the received key code is a key code for the second mode. When the receiver is in the second mode, the key delivery module delivers the received key code to the pre-installed application.
