CONTROL DEVICE FOR RECEIVERS OF INFORMATION BASED ON THE PROPAGATION OF THE ELECTROMAGNETIC FIELD, PARTICULARLY FOR TELEVISION SETS, AND AN EXERCISE MACHINE COMPRISING SAID DEVICE

摘要

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).
