Product Description


 CATV QAM Modulator DMB-5100 not only succeeds to DMB-5000 high reliability and stability, but also provides user with powerful additional functionalities. The Modulator can receive QPSK signal, QAM signal, or DS3 signal directly to extract MPEG TS. The MPEG TS can be multiplexed with other MPEG TS from ASI to one MTPS. Finally the MTPS will be send to QAM modulation module to realize DVB-C modulation and upconvert to RF. The modulator can meet all of the requirements of Digital Cable TV operators economically and effectively.


Main features:

  • Comply to ITU-U J.83, Annex A (DVB), B(Open Cable)
  • PID filter and remapping can be configured
  • PSI/SI information updating possible
  • Filling MPEG TS automatically and delete empty packet intellectively
  • PCR correction supported
  • 188/204 data packet adaption automatically
  • RF output frequency scope 48~862MHz, in 0.1MHz step
  • Output level can be adjusted in 100~113dBuV
  • Powerful MPEG TS remux and QAM modulation conversion
  • Front panel -20dB RF testing output provided
  • Parameter record when power off, it can store 99 channels parameters
  • Web browser remote control, network upgrade supported
