EDGE-QAM DVB-Modulator

High Quality IP2QAM (DVB-C) or COFDM (-T) Modulator

EDGE-QAM = IP Streams to DVB-C RF-Modulator

Our IP2QAM Modulators are available in different numbers of RF-output Channels and Features - COFDM (DVB-T) upon request...
Optimal designed to perfectly work together with our DVB- IP Streamer Gateways

HDC-5004 = IP to 4 adjacent DVB-C channels (or T, ... upon Request)

HDC-5004 DVB-Modulator

The BLANKOM HDC-5004 is a 5th generation IP to QAM modulator 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 (UHD/HEVC/MPEG2/MPEG4 HDTV compatibel) The output consists of 4 DVB-C carriers, each with up to 256QAM modulation. Each of the 4 output multiplexes are also provided as MPTS IPTV streams, UDP/RTP, unicast or multicast at the IPTV output port. Mayor operational projects: Church -> Residence insertion into aditional RF channels, ... Info-Channels prividing from our encoder-streamers ...

HDC-5016 32, 48, 64 QAM Modulator


The BLANKOM HDC-5016 /32 /48 /64 is the 5th Generation IP to QAM- Modulator with multiplexer and CA-scrambler. The IPTV input channels can be SPTS or MPTS, unicast RTSP or multicast UDP/RTP. The internal multiplexer creates 16…64 streams with any combination of content or pass through. The output consists of 16-64 DVB-C agile carriers within 192 MHz bandwidth, each with up to 256QAM modulation. Each of the 16/32… 64 output multiplexes are also provided as MPTS IPTV streams, UDP/RTP unicast or multicast at both data ports to feed sub-headends with this already prepared Bouquets’ via IP backbones. *) = depending on model acc. to the number of RF channel outputs
