DVBS2 - COFDM

The MPEG2 transport package is then modulated
in COFDM format and converted to the output
channel (UHF or VHF and with a maximum
bandwidth of 8 MHz) using an agile up-converter. The DVBS2 transmodulator with COFDM receives
a satellite transponder in some DVBS (QPSK) or
DVBS2 (QPSK or 8PSK) modulation formats and
demodulates it by obtaining an MPEG-2 transport
package. The programming of the transmodulator operating
parameters (input frequency, output channel,
modulation format and adaptation of services
mainly) is performed through the universal
programmer (ref. 7234).
