The Virtuoso CP4400 is the ideal toolbox for T2-MI generation and regional adaptation in DVB-T2 Single Frequency Networks (SFN). Thanks to its flexibility it simplifies the implementation of critical differentiators for network operators.

The Virtuoso CP4400 offers a flexible and highly cost effective solution for generation of T2-MI transmitter feeds and regional adaptation of DTT multiplexes. CP4400 can operate as a central DVB-T2 Gateway or based on Nevion’s deterministic remultiplexing technology for regionalization of DTT multiplexes.

The deterministic remultiplexing enables feeding of transmitters in multiple SFN regions using the same Transport Stream (TS) as used in a pre-existing Direct to Home (DTH) satellite system.

In addition to the powerful TS processing capabilities, the Virtuoso CP4400 offers several tools for the improvement of the transmission quality such as input monitoring, redundancy switching and diversity reception for TSoIP streams. Nevion cProcessors can be configured via an easy to-use web interface. Scheduled software upgrades can be performed via Nevion’s NMS or third party NMS.


  • Scalable platform to perform DVB-T2 adaptation on multiple multiplexes to reduce the cost per multiplex
  • Flexible architecture to combine processing features on the same unit
  • Configurable monitoring depth to adapt to the operational requirements
  • Flexible interfaces eliminate the need for format conversion equipment
  • Persistent local alarm log and easy integration with NMS


  • T2-MI generation for up to seven multiplexes in central head-ends
  • Regional adaptation in DVB-T2 SFN networks where generating identical transmitter feeds is crucial
  • Regionalization of DVB-T2 multiplexes by reusing the pre-existing DTH signal
