Product Overview
NDS3364 64 in 1 IP QAM modulator is a Multiplexing-scrambling-modulating all-in-one device developed by DEXIN. It has 64 multiplexing channels, 64 scrambling channels and 64 QAM (DVB-C) modulating channels, and supports maximum 512 IP inputs through the 4 data ports and 64 non-adjacent carriers (50MHz~960MHz) output through 2 RF output interfaces. The device is characterized with dual RF output ports which broaden the bandwidth for QAM carriers.
Key Features
* 6 GE inputs (4*RJ45, 2*SFP)
* Supports up to 512 IP inputs over UDP/RTP
* Max 840Mbps and 512 IP inputs for each GE input
* Supports multiplexing with accurate PCR adjusting, CA PID filtering, PID remapping and PSI/SI editing
* Supports up to 256 PID remapping per channel
* Support DVB general scrambling system (ETR289), simulcrypt standards ETSI 101 197 and ETSI 103 197
* Support 64 multiplexed or scrambled IP outputs over UDP/RTP/RTSP
* 64 non-adjacent QAM carriers output from 2 RF interfaces, compliant to DVB-C (EN 300 429) and ITU-T J.83 A/B/C
* Supports RS (204,188) encoding
* Support Web-based Network management
