OVERVIEW

DMB-24E Series Universal Digital Professional Modulator, with independent HDMI/Tune/IP/modulation modules for option in back panel. Each module supports 4*HDMI/4*Tuner/4*RJ45 Port 100M Ethernet interface IP input. Each modulation module supports 4* frequencies output, 128*IP (SPTS/MPTS) + 2*ASI in.
On the inner Main board (Front panel), support 1 group (4*RF) output or 2*group (8*RF) output for option. Support ISDB-T/DVB-T/DVB-C/ATSC adjacent RF output in one device (the adjacent refer to each one modulation module).
It is flexible configuration, you can chose different number of modules with 4/8/12/16/20/24*HDMI/
Tuner/RJ45 Port input, 4/8/12/16/20*RF out as per needs accordingly. Coming with professional and high cost-performance modulator for Digital TV headend.

 

FEATURES

  • Up to 6 independent modules in rear panel
    Each module data input: 4*HDMI / 4*Tuner (DVB-S/S2, DVB-T/T2, DVB-C, ISDB-T/Tb, ATSC-T, DTMB input for option, If DVB-T/T2, ISDB-T/Tb input, Max. support 12-Channel Input) / 4*RJ45 Port 100M Ethernet interface (Each port supports 32*IP (SPTS /MPTS) input, Total 128*IP)
  • Up to 3 independent modulation modules in rear panel(Second layer)
    Each module data input: 128*IP (SPTS/MPTS) + 2*ASI in
    Each module output 4*RF DVB-T/DVB-C/ATSC/ISDB-T/DTMB for option,
