Overview


FUTV4443B is a high performance and cost-effective mux-scrambling QAM modulator designed by FMUSER. It adopts inner drawer-type structural design which greatly facilitates the change of modules (4 Tuner/4ASI) as needed. To meet customers’ various requirements, this device is also equipped with 1 ASI in, 1 RF in, 1RF out and 2 ASI out port. After 4 channels multiplexing, scrambling and QAM modulating process, then it gives 4 RF output (4 adjacent frequencies).
The device is characterized with high integrated level, high performance and low cost. This is very adapting to newly generation CATV broadcasting system.




Features


*Support 4 ASI (or 4 Tuners with CAM/CI) input, 1 ASI input for re-mux, 1 RF input for mix

*Fully support DVB-C (EN300 429) and ITU-T J.83A/B/C
*Fully support DVB general scrambling system description ETR289, simulcrypt standard ETSI 101 197 and ETSI 103 197
*Every tuner has been accompanied with 1 CAM and 1 CI-slot, one CAM can decrypt max 8 programs
*Support 4 channels multiplexing, 4 channels scrambling and 4 channels QAM modulating
*Support accurate PCR adjusting
*Support PSI/SI editing and inserting
*Excellent RF output performance index, MER>=40db
*Support LCD display and keyboard

*Support Web management
