Terra TTX420C twin DVB-T/T2/C to DVB-T  transzmodulátor két CI interfésszel

Modular reception system

Converting of 2  DVB-T/T2/C modulated
input signals into 2 COFDM modulated DVB-T channels.

  • common interface
  • TS processing:

  service multiplexing - any input to any output
  PCR restamping
  PSI/SI regeneration
  NIT generation
  PMT version monitoring

  • Web control and SNMP monitoring
  • loop through RF distributing at input and output
  • DIN rail or wall mounting
  • robust die-cast housing
  • connectors:

  RF input/output - type F
  Ethernet control interface - RJ-45
  2xCI ports - PCMCIA (tdx420C, ttx420C)
  screw terminal block for DC entry
  power distribution bus
