Digital Media Gateway DMG 3100

The DMG 3000/3100 advanced multiplex software simplifies engineers' deployment and operational routines. Developed specifically for digital cable operators, the multiplexer performs full analysis of source PSI/SI and PSIP tables, with automatic regeneration of all tables as required, up to a maximum 250 multiplexes.

Sencore's DMG 3000/3100 offers a high performance QAM output module for direct insertion of digital services into the cable network. Based on a full digital-modulation and up-conversion architecture, the QAM Output module delivers a clearer signal, and makes future upgrades easier.

 

  • 1RU and 4RU chassis
  • Gbit/s IP (electrical or optical), ASI, DVB-S/ S2, DVB-T and DVB-C inputs
  • Any combination of inputs in the same chassis.

Maximum:
- 45 ASI
- 28 DVB-S/S2, DVB-T, DVB-C

  • Gbit/s IP (electrical or optical), ASI and QAM outputs supporting MPTS and SPTS
  • Multiplexing
  • PSI/SI regeneration
  • PSI/SI/PSIP input analysis
  • Up to 28 DVB common interface slots for DVB descrambling
  • Support for AES SW descrambling
  • Support DVB and AES scrambling, simulcrypt interface based
  • Intuitive web-based user control
  • Dual redundant hot-swappable power supplies (Option, 4RU only)
  • Monitoring of power and fans (4 RU only)
  • SNMP Alarm MIB
  • SOAP/XML Interface for external control
  • Central Head-end
    The ideal solution for deployments requiring aggregation of services from multiple sources, service processing and preparation for QAM broadcast over cable networks.
  • Remote Head-end
    With IP, DVB-T or ASI input sources, powerful edge processing capabilities, high density QAM output alongside decoder options for analog simulcast, operators can deliver all broadcast services via a common platform.
  • Contribution
    High throughput ASI feeds, multiplexing functionality, and an easy to use user interface make dynamic service adjustments possible.
  • Regional Adaptation
    For insertion of local programming at regional broadcast locations. Transparent mode enables direct transport stream forwarding for network conversion applications.
