Detailed Info
GQ-3654 Multiplexing QAM Modulator is a compact and cost-effective DVB MPEG-2 TS multiplexing QAM modulator. It re-multiplexes up to 4 ASI transport streams inputs into MPEG-2 multiprogram transport streams (MPTS). The MPEG-2 MPTS are then routed to QAM modulation and RF upconverter. GQ-3654 combines re_multiplexer, PID Filter and Re-mapping, digital cable QAM (J.38 A/B/C) modulator in a single unit. GQ-3654 adapts Ethernet Management interface complying with SNMP protocol, which allows real-time status monitoring and control. It can obtain/replace the PSI/SI information coming from each input port and multiplex them up to 1 TS with PCR Error Correction. It is mainly applied to transmitting Digital Cable TV signal in HFC, MMDS and MUDS systems.
Features:
Fully comply with ETSI 300429 standard
188/204 packet auto-identification, displaying input data format real time
Large cache, support burst input bit stream,
The QAM modulation chosen among 16QAM, 32QAM, 64QAM, 128QAM and 256QAM
