Abstract
A remote control unit radiates signals of operated program selection keys (3) via an infrared transmitter circuit (10, 11, 12). In order to simplify the selection of one of several TV programs for the user, the remote control device has a receiver circuit (18 to 23). The latter detects picture signals of the TV programs to be selected via program selection keys (3). A storage unit stores these picture signals. To each of the program selection keys (3) on the remote control set a picture display (6) is assigned. A control circuit (24, 29, 30) distributes the picture signals from the storage (25) cyclically to the picture displays (6).
