TWIN DTT TRANSMODULATORS WITH REMULTIPLEXING FUNCTION. TWO DTT OR QAM OUTPUT MUXES PER MODULE 

DVB-T2 COMPATIBILITY FOR DVB-T OR QAM RECEIVERS

These twin multiplexers distribute two different COFDM or QAM outputs services from the TWO DTT input multiplexes, either in DVB-T or DVB-T2 format.

The main function is the regeneration of DTT signals and/or input services filtering (Ref. 565101) or the DVBT/T2 - QAM re multiplexing (Ref. 656201). They also offer a new feature which allows the possibility of distributing DVBT2 signals to those TVs or DTT/QAM receivers incompatible with this new broadcast standard.

They can mix FTA and encrypted services in the same multiplex and also include a SECURE DCY to prevent CAM card flooding in case new PIDs appear.

Highlights:

  • Fully configurable TWIN (2-multiplex) output.
  • Mix in the same output multiplex services from both DVB-T or DVB-T2 input multiplexes.
  • Edit the transport stream parameters (TS_id, ON_id and LCN).
  • Compatible with professional CAM modules/cards.

Main features:

  • Configurable and remote-monitored via CDC.
  • Set the services of the output multiplexes by only adding the desired PIDs.
  • Information about the useful rate of the input services.
  • Information about the output channel occupancy.
