The DVBS2 transmodulator with COFDM CI re-
ceives 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 MPEG2 transport package is then modulated

in COFDM format and converted to the output
channel (UHF or VHF and with a maximum band-
width of 8 MHz) using an agile up-converter.
Additionally, it incorporates a Common Interface
slot for inserting a conditional access module
(CAM) to permit the unscrambling of services.

The programming of the transmodulator operat-
ing parameters (input frequency, output channel,
modulation format and adaptation of services
mainly) is performed through the universal pro-
grammer (ref. 7234).
