DMB-2408 Multi-channel Remodulator designed with high compact for capture signals from satellite DVB-S/S2 tuner and convert to digital RF(DVB-T or DVB-C for option), moreover built-in features of multiplexing and scrambling. It’s the professional and high cost-performance equipment tailor for hotel distribution TV. Furthermore, the four CAMs accompanied can descramble the programs from 8 Tuner (4*Tuners Fixed+4 Tuners/pluggable 2 modules) and IP input.
Considering for future-proof features DMB-2408 has 8 tuner inputs and equipped with IP input(128SPTS/MPTS) and IP output(4MPTS) which could be expanded the channels to IPTV system or capture signals from IP source.

FEATURES

  • Up to combined with 4*DVB-C/S/S2/T/T2 Tuners(Fixed) and 4*DVB-C/T/T2/S/S2/ATSC Tuners with CAM (pluggable 2 Modules)
  • 128*IP(MPTS/SPTS) input over UDP and RTP.
  • For DVB-T output: 4 groups multiplexing +4 groups DVB-T modulating
  • For DVB-C output: 4 groups multiplexing + 4 groups scrambling + 4 groups DVB-C modulating
  • One CAM can decrypt multiple programs from any Tuners and IP input
  • 4 IP (MPTS) output over UDP and RTP protocol
  • Demodulation Module (4*RF in/loop out + 4*CAM + 4*Smartcard)
  • Easy to adjust the PCR in precisely.
  • Offering PID Remapping and capable of rebuild & edit the PSI/SI.
  • Easy to configure via Web-based management.
