Product Description


OTV-1632 32 in 1 IP QAM Modulator is DIBVIEW's Mux-scrambling-modulating all-in-one device.


OTV-1632 32 in 1 IP QAM Modulator supports maximum 1024 IP input through the 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) (SFP interface optional)

  • 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
