EDGE-QAM & Transmodulators
HDC-5016-32-64
IP to 16/32/48/64 QAM EDGE Modulator with Multiplexer & Scrambler
Convert up to 512 IPTV input streams into as many as 64 DVB-C QAM carriers from a single 1U unit — with integrated multiplexing, simulcrypt scrambling and web-based management for efficient cable head-end distribution.
Overview
The VIZOBOX HDC-5016-32-64 is a fifth-generation EDGE-QAM modulator that multiplexes IP input streams into adjacent or non-adjacent DVB-C QAM RF carriers for cable TV head-end distribution. It accepts up to 512 TS-over-UDP/RTP channels via redundant GigE inputs (max. 840 Mbps per port) and delivers 16 to 64 QAM carriers on a single RF output, compliant with DVB-C EN 300 429 Annex A/C and ITU-T J.83 A/B. An internal multiplexer with PID remapping, PSI/SI editing and DVB simulcrypt scrambling, plus parallel IP MPTS output over two GigE ports, make it a complete IP-to-QAM edge solution available in 16-, 32-, 48- and 64-channel variants.
Highlights
- IP to 16/32/48/64 QAM modulation with 2+1 GigE inputs and one combined RF output
- Up to 512 channels TS over UDP/RTP unicast/multicast with IGMP V2/V3, max. 840 Mbps per GigE input
- 16 to 64 non-adjacent QAM carriers compliant with DVB-C (EN 300 429) Annex A/C and ITU-T J.83 A/B
- Integrated multiplexer and scrambler: CA PID filtering, up to 180 PID remappings per channel, PSI/SI editing and accurate PCR adjustment
- DVB simulcrypt scrambling (ETR 289, ETSI 101 197, ETSI 103 197) with up to 4/6 CAS
- Broadcast-grade output quality with MER ≥ 40 dB and web-based network management
