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).
