NDS3348 catv Modulator 48 channels IP QAM Modulator
Product Description
Product Overview
NDS3348D IP QAM modulator is Mux-scrambling-modulating all-in-one device developed by DEXIN. It has 48 multiplexing channels, 12 scrambling channels and 48 QAM (DVB-C) modulating channels, and supports maximum 1536 IP input through the 3 GE ports and 48 non-adjacent carriers (50MHz~960MHz) output through the RF output interface. The device is characterized with dual RF output ports which broaden the bandwidth for QAM carriers
Key Features
Max 1536 IP input thru 3 GE ports (SFP interface optional)
Up to 512 PIDs remapping per output channel
Supports 6 simulcrypt CAs and 12 scrambling channels
48 IP out over UDP/RTP/RTSP: IP 1~24 out thru Data1, IP 25~48 out thru Data2
48 non-adjacent QAM carriers output: carrier 1~24 out thru RF1, carrier 25~48out thru RF2
Supports RS (204,188) encoding
Supports accurate PCR adjusting/CA filtering, PID remapping and PSI/SI editing
Web-based Network management
