DVB-IP Gateway and Edge

The WISI TANGRAM video platform is a high-density digital TV headend for contribution of digital TV via IP networks and end-to-end IPTV solutions such as video-on-demand, connected TV and OTT (Over The Top) or Web TV. The platform is highly customizable and offers advanced DVB stream processing in a small footprint 1 RU chassis concept. The TANGRAM chassis can be equipped with 6 + 1 modules. The six rear loaded modules have different functionalities, and can perform all necessary signal processing functions.

  • Small footprint in 1RU chassis
  • Hot swappable fan tray
  • Fully redundant concept (1+1, n+1)
  • Optional scrambling and multiplexing function
  • Redundant power supplies ensure operational capability
  • Each module can be equipped in every slot

Maximum performance in every network

The TANGRAM platform can be used in a central or distributed headend architecture and provides the following processing functions in a central location: DVB-IP gateway for DVB-S/S2/ -C / -T / -T2, descrambling, remultiplexing, scrambling, PSI/SI processing and modulation.

In a decentralized architecture with regional hubs, the modulation is done in the hub site and the aggregated digital TV streams are transported via an IP network and are terminated in Edge-QAMs, -COFDMs*, -PALs and -FMs for remodulation and transmission in HFC networks.

The TANGRAM chassis can be equipped optionally with two load sharing redundant power supplies (DC or AC) and contains high-performance monitored fans for cooling. Modules, fans and power supplies are hot swappable.
