IP to QAM (DVB-C) Modulator

HDC-5004

BLANKOM HDC-5004 IP to QAM Modulator

IP to QAM (DVB-C) Modulator, with up to 512 IPTV in, with Multiplexer, with 4 RF and 4 MPTS IP out.

⟩⟩⟩ 5. Generation BLANKOM® Hybrid DVB & IPTV Headend Technology. IPTV input, DVB-C and IPTV output with multiplexer and scrambler.
The IPTV input channels can be SPTS or MPTS, unicast or multicast. The internal multiplexer creates 4 streams with any combination of content. The output consists of 4 DVB-C carriers within 32 MHz bandwidth, each with up to 256QAM modulation. Each of the 4 output multiplexes are also provided as MPTS IPTV streams, UDP/RTP/RTSP, unicast or multicast at the both data ports.

  • 4 IP inputs, 1 RF output
  • Up to 512 channels TS over UDP/RTP, unicast and multicast, IGMP v2v3 input
  • Max 100 Mbps for each ethernet input
  • 4 adjacent QAM carriers output, compliant to DVB-C (EN 300 429) and ITU-T J.83 A/B
  • 4 multiplexed or scrambled TS over UDP/RTP/RTSP output
  • Accurate PCR adjusting
  • CA PID filtering, remapping and PSI/SI editing
  • Up to 780 PIDS remapping per channel
  • Support DVB general scrambling system (ETR289), simulcrypt standards ETSI 101 197 and ETSI 103 197
  • Supports RS (204,188) encoding
  • Web-based Network management
  • Broadcast quality
  • Professional quality, breakthrough price

BLANKOM HDC-5004 modulates up to 512 SPTS or MPTS IPTV channels into 4 QAM (DVB-C) carriers within 32 MHz bandwidth, in broadcast quality.

Features

BLANKOM HDC 5004 is an IP to QAM modulator with internal multiplexer and scrambler. Up to 512 IPTV challes can be multiplexed and modulated into 4 DVB-C channels. The RF frequencies are configurable.

It has also MPTS stream output of the multiplexed channels. Thus it can beused as SPTS in MPTS out IPTV Multiplexer.

The unit can be controlled remotely through web, with any web browser.
