Features and Benefits

  • Transmodulation from DVBT/C to DVBT/C, with the inclusion of CI interfaces for descrambling the unit can deliver services transparently or through PID filtering selected digital services
  • Regeneration of the DVBT services to a DVBT- COFDM signal, transparent or select services with PID filtering
  • Integrated conditional access interface for both channels
  • Internal NIT generation available
  • PID filtering available
  • Input range 110-878MHz DVBT/T2
