channel (UHF or VHF and with a maximum
bandwidth of 8 MHz) using an agile up-converter.
Additionally, ref. 563301 incorporates a Common
Interface slot for inserting a conditional access
module (CAM) to permit the unscrambling of
services.
The DVBS2 transmodulator with COFDM CI 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 MPEG2 transport package is then modulated
in COFDM format and converted to the output
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).
