It has 8 tuner inputs. After multiplexing and modulating process, it gives 4 DVB-T carrier output through one RF port. To meet customers' various requirements, this device is also equipped with data port for 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 can descramble the programs input from 8 Tuner and IP input. HP8544D can be upgraded and controlled through network system, which allows it widely used in digital broadcasting network and provide good signals for scientific laboratory and DVB-T STB.Key Features* 4 Tuner FTA (DVB-C/T/T2/S/S2 optional) + 4 Tuner with CAM (DVB-C/T/T2/S/S2/ATSC optional) input* Demodulation Module (4*RF/Loop out + 4*CAM + 4*Smartcard)* One CAM can decrypt multiple programs from Tuners and IP* Maximum 128 IP input (MPTS/SPTS) over UDP and RTP protocol* 4 groups multiplexing +4 groups DVB-T modulating* 4 IP (MPTS) output over UDP and RTP protocol* Support accurate PCR adjusting/ PID Remapping/ PSI/SI rebuilding and editing* Web-based NMS managementSpecificationInput4 Tuner(DVB-C/T/T2/S/S2 optional)+4 Tuner with CAM(DVB-C/T/T2/S/S2/ATSC optional)128 IP(SPTS/MPTS) input over UDP and RTP,RJ45, 1000M/100M , Unicast/Multicast Tuner SectionDVB-CStandardJ.83A(DVB-C), J.83B, J.83CInput Frequency30 MHz~1000 MHzConstellation16/32/64/128/256 QAMDVB-T/T2Input Frequency30MHz ~999.999 MHzBandwidth6/7/8 M bandwidthDVB-SInput Frequency950-2150MHzSymbol rate2-45MspsSignal Strength-65~-25dBmFEC Demodulation1/2, 2/3, 3/4, 5/6, 7/8 QPSKDVB-S2(Version 1)Input Frequency950-2150MHzSymbol rateQPSK 1~45Mbauds; 8PSK 2~30MbaudsCode rate1/2, 3/5, 2/3, 3/4, 4/5, 5/6, 8/9, 9/10ConstellationQPSK, 8PSKDVB-S2(Version 2)Input Frequency950-2150MHzCode rate1/2, 3/5, 2/3, 3/4, 4/5, 5/6, 8/9, 9/10ConstellationQPSK, 8PSK, 16APSK, 32APSKSymbol rateQPSK 1~45 Msps; 8PSK 2~30 Msps;16APSK 1~45 Msps; 32APSK 1-32 MspsATSC-TInput Frequency54MHz~858MHzBandwidth6M bandwidthDescramblingCAM/CI 4 setsMultiplexingMaximum PID Remapping256 per input channelFunctionPID RemappingAccurate PCR adjustingGenerate PSI/SI table automaticallyModulationDVB-TStandardEN300744FFT mode2K Bandwidth6M, 7M, 8MConstellationQPSK, 16QAM, 64QAMGuard Interval1/4, 1/8, 1/16, 1/32Code Rate1/2, 2/3, 3/4, 5/6, 7/8MER≥42 dBRF frequency50~960MHz, 1KHz stepRF out4*DVB-Tnon-adjacent carriers combined output, 40M total bandwidth limitationRF output level-28~ -3 dBm (79~104dbµV), 0.1db stepStream out4*MPTSover UDP and RTPout (RJ45, 1000M/100M Unicast/Multicast)SystemWeb-based NMS supportEthernet software upgradingGeneralDimension482mm×300mm×44.5mm(W*D*H)Temperature0~45ºC(Operation) ; -20~80ºC(Storage)Power AC100V±1050/60Hz; AC 220V±10%,50/60HZPrinciple Chart
