Product Overview

 IP QAM modulator is  Mux-scrambling-modulating all-in-one device. It supports maximum 1024 IP input through the GE port 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

* 2 GE input, Data1 and Data2 (SFP interface optional)

* Supports up to 1024 channels TS over UDP/RTP, unicast and multicast, IGMP v2v3

* Max 840Mbps for each GE input

* Supports accurate PCR adjusting

* Supports CA filtering, PID remapping and PSI/SI editing

* Supports up to 256 PIDS remapping per channel

* Support 32 multiplexed or scrambled TS over UDP/RTP/RTSP output

* 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
