A control device for receivers of information based on the propagation of
the electromagnetic field, particularly for television sets, comprises an
input interface (20) for receiving analogue and digital television
signals (100, 110); tuning means (30) for selecting an analogue channel
(100a) or a digital channel (110a); a decoding circuit (40); an output
interface (50) for connecting the device (1) to a television set (10) and
sending a main signal (120) incorporating content to be displayed; a
selection block (60) for selectively connecting to the output interface
(50) an analogue output (31b, 32b) of the tuning means (30) or an output
(40b) of the decoding circuit (40); a processing unit (70) connected to
the tuning means (30) and for sending a first signal (130) representing a
channel to be selected; the processing unit (70) being connected to the
selection block (60) to send a second signal (140) and identify which
signal must be sent to the output interface (50); the processing unit
(70) is controlled by a controller device (80), so that it receives a
control signal (150) and generates the first signal (130) and/or the
second signal (140).
