Outline
 

STM****0 4 in 1 mux-scrambling QAM Modulator is a high performance and cost-effective ASI mux-scrambling QAM modulating device latest designed by Sighton Company. It provides *6 ASI interface. After 4 channels multiplexing, scrambling and QAM modulating process, then it gives 4 RF output (4 adjacent frequencies by 1 RF port) and gigabit IP output. The device is characterized with high integrated level, high performance and low cost. This is very adapting to newly generation CATV broadcasting system.
 

• Support *6 ASI , 4 ASI , 8 DVB-S2 tuner optional
• Fully support DVB-C (EN**0 **9) and ITU-T J.*3A/B/C
• Fully support DVB general scrambling system description ETR**9, simulcrypt standard ETSI **1 **7 and ETSI **3 **7
• Support 4 channels multiplexing, 4 channels scrambling and 4 channels QAM modulating
• Support gigabit IP output
• Simultaneously support 4 simulcrypt CA
• Support accurate PCR adjusting
• Support PSI/SI editing and inserting
• Excellent RF output performance index, MER≥*0db
• Support LCD display and keyboard
• Support SNMP management
