Introduction

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 channel (UHF or VHF and with a maximum

bandwidth 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 operating parameters (input

frequency, output channel, modulation format and adaptation of services

mainly) is performed through the universal programmer (ref. 7234).

NOTE: The complete user manual is available in the CD

that is provided with the product.
