The COFDM transmodulator turns a TV or
radio channel (chosen by the user) from the
existing channels in a terrestrial digital tele-
vision 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), with possibility of
nicam modulation.
To do this, the unit carries out the COFDM
demodulation of the input channel (multi-
plex), obtaining an MPEG-2 TS signal

Product reference
Indicate the program-
med output channel
(MPEG-2 transport stream), to carry out the
subsequent modulation, according to the
standard, of the audio and video signals of
the selected program in any channel or fre-
quency between 46 and 862 MHz.
It is also possible to control the unit via a PC
as is explained in section 6.
The COFDM-PAL transmodulator disposes
of a BIII and UHF input and output in the
upper F connectors with the aim of enabling

modules.
It also has an RF input and output connector
so as to be able to mix the output channel
for their subsequent amplification.
