The COFDM-PAL transmodulator turns a TV
or radio channel (chosen by the user) from
the existing channels in a multiplex (COFDM
modulation and an approximate bandwidth
of 7/8 MHz) into a VHF/UHF channel (PAL
modulation and a bandwidth of 7/8 MHz).
To do this, the unit carries out the COFDM
demodulation of the input channel
(multiplex), thereby obtaining an MPEG-2 TS
signal (MPEG-2 transport stream) to carry
out the subsequent modulation (according
to the standard) of the audio and video sig-
nals of the selected program in any channel
or frequency between 46 and 862 MHz.
It is also possible to control the unit from a
PC as explained in section 6.
The COFDM-PAL transmodulator disposes
of an BIII / UHF input and output in the
upper “F” connectors with the aim of faci-
litating the passing of the input signal to
various modules.
It also has an RF input and output so as to
be able to mix the output channels for their
subsequent amplification.
