Product Overview
NDS3332 32 in 1 IP QAM Modulator is DEXIN’s Mux-scrambling-modulating all-in-one device. It supports maximum 1024 IP input through the 3 GE ports and 32 multiplexing scrambling QAM (DVB-C) modulating channels with non-adjacent carriers (50MHz~960MHz) output through the RF output interface. Its pay-as-you-grow modular design and flexible configuration are making it extremely scalable, very reliable with high performance, all of which are adaptable to newly generation CATV broadcasting system.
Key Features
* 3 GE ports (max 1024 IP in):
Data1 & Data2 bi-directional ports, max 512 IP in, 32 IP out
Data port (located on front panel), max 128 IP in
* Max 840Mbps for each GE input
* Supports accurate PCR adjusting/CA filtering, PID remapping and PSI/SI editing
* Supports up to 256 PIDS remapping per channel
* Support 32 IP output through Data1 & Data2 over UDP/RTP/RTSP
* 32 non-adjacent QAM carriers output, compliant to DVB-C (EN 300 429) and ITU-T J.83 A/B
* Supports RS (204,188) encoding
* Support Web-based Network management
