Digital TV Headend 4 in 1 DVB-C Modulator,(DT-DVB-CM-4) is a high performance and cost-effective DVB-C modulator designed
by DAYTAI. It has 8 tuner inputs, after multiplexing, scrambling and modulating process, then it gives 4 DVB-C non-adjacent
carriers output. To meet customers’ various requirements, this device is also equipped with 128 IP input and 4 MPTS output
over UDP and RTP. Its pluggable structure design greatly facilitates the change of modules as needed. Moreover, the four
CAMs/CIs accompanied and BISS modules can descramble the programs input from 8 Tuner and IP input.
DT-DVB-CM-4 can be upgraded and controlled through network system, which allows it to be widely used in setting
up digital broadcasting network and very adaptable to newly generation CATV broadcasting system.Power:AC
100V±1050/60Hz; AC 220V±10%, 50/60HZ,Power Plug:European standard Plug or American standard Plug is optional.
★Features
⊙Support BISS descrambling
⊙Web-based NMS management
⊙4 IP (MPTS) output over UDP and RTP protocol
⊙Integrated demodulating and multiplexing functions
⊙One CAM can decrypt multiple programs from Tuners and IP
⊙Demodulation Module(4*RF/Loop out + 4*CAM + 4*Smartcard)
⊙maximum 128 IP input(MPTS/SPTS) over UDP and RTP protocol
⊙4 groups multiplexing + 4 groups scrambling + 4 groups DVB-C modulating
⊙Support accurate PCR adjusting, PID Remapping, PSI/SI rebuilding and editing, A/V PID filtering
⊙4 Tuner (DVB-C/T/(T)/S/S2/S2X/ISDBT optional) + 4 Tuner with CAM (DVB-C/T/(T)/S/S2/S2X/ATSC/ISDBT optional)
