A semiconductor device for a tuner generates a local oscillation signal inside or selects a local oscillation signal introduced from the outside, and controls the power consumption of the circuit used for generating the local oscillation signal. Through the web access the user is provided with the information necessary to establish a connection with an application by way of the virtual desktop. At least two axially parallel fingers of an expander are temporarily inserted into the coil interior for reshaping the wound circular cylindrical coil and are displaced in a diverging relative movement after the insertion and while doing so expand the initially circular cylindrical coil into the coil having the different cross section.
