SMP330 Edge QAM Modulator

SMP330 Edge QAM is Wellav’s new generation modulator. It can support up to 24 RF QAM channels, organized as three independent blocks of 8 channels.

Features:

Based on customer requirements, SMP330 can be configured to support 12 DVB-T channels as well. With ASI and IP input/output options, SMP330 can support MPTS and SPTS input with multiplexing, private data insertion and scrambling capability. SMP330 provides a cost-effective yet scalable solution for network operators to re-distribute its content via HFC network or to offer VOD services.

  • Output 24 RF-QAM channels or 12 DVB-T channels for both SD and HD programs
  • Support programs input from both ASI (four different sources) and GBE IP (up to 256 SPTS)
  • Support stream processing including PID remapping and EPG data insertion
  • Option to add DVB-simulcrypt scrambling capability
