CATV Modulator Multi Channel FTA 4 8 Tuners to RF for Radio TV Broadcasting Equipment
Overview DMB-24EC Series 4/8 channels RF TO RF broadcast transmodulator, demodulate the modulated RF signal and multiplexing, then up-converter modulating adjacent carrier out.The tuners input support two tuner different types chose from DVB-S/S2/T/T2/C/ISDB-T/ATSC-T. Not only tuners input, this item supports tuners and HDMI mixed input. DIGICAST DMB-24EC Transmodulator is a high density demodulating and modulation all in one digital broadcast headend equipment that has 4/8 FTA tuner inputs to convert to 4 or 8 non-adjacent carrier outputs with multiplexing. It also supports 128*MPTS/SPTS UDP/IP inputs and 1*MPTS & 127*SPTS UDP/RTP IP output through DATA port and TS input for re-mux through ASI ports. This is the new generation equipment which conversion RF programs to other RF standard and IP TS that are easily managed via web management to help transmission all of your programs to your local RF system. *Tuner input: Up to 4/8 FTA Tuners input* Tuner standard option: DVB-S/S2, DVB-T/T2, DVB-C, DTMB, ISDB-T/Tb, ATSC* Two separate ASI input for External TS Multiplexing * IP stream output: 128*SPTS* Output IP protocol: UDP/RTP* Low power consumption and high reliability with * MTBF(Mean Time Between Failure) ≥ 50000 Hours * Easy-to-Use System Management via web * Highly Compact, High-Integrate * Support LCN (Logical Channel Number) FTA Tuners input(optional) DVB-S/S2 Input Frequency 950-2150MHz Symbol rate 1~54MSps (DVB-S QPSK)1~60MSps (DVB-S2 QPSK)1~60MSps (DVB-S2 8PSK)1~58MSps (DVB-S2 16APSK)1~55MSps (DVB-S2 32APSK) FEC Demodulation 1/2, 2/3, 3/4, 5/6, 7/8 (DVB-S QPSK)1/4, 1/3, 2/5, 1/2, 2/3, 3/4, 4/5, 5/6, 8/9, 9/10 (DVB-S2 QPSK)3/5, 2/3, 3/4, 5/6, 8/9, 9/10 (8PSK)2/3, 3/4, 4/5, 5/6, 8/9, 9/10 (16APSK)3/4, 4/5, 5/6, 8/9, 9/10 (32APSK) Signal strength -65 ~ -25dBm Roll off 0.20; 0.25; 0.35 (Only DVB-S) Demodulation mode QPSK, 8PSK, 16APSK, 32APSK (Only DVB-S2) LNB polarity selection Vol 0, 13V, 18V Selectable LNB band selection Tone 0/22Khz Selectable Input impedance 75 Ω FEC (Code Rate) 1/2, 2/3, 3/4, 5/6, 7/8 DVB-T/T2 Frequency Range 30MHz-1000Mhz Bandwidth 6Mhz, 7Mhz, 8Mhz FEC Demodulation DVB-T: 1/2, 2/3, 3/4, 5/6, 7/8 DVB-T2:1/2, 3/5, 2/3, 3/4, 4/5, 5/6 Constellation QPSK, 16QAM, 64QAM, 256QAM (Only DVB-T2) ISDB-T Frequency range 30-900MHz Bandwidth 6MHz Constellation DQPSK,QPSK,16QAM,64QAM FEC(code rate) 1/2,2/3,3/4,5/6,7/8 Interleave 0,4,8,16 Guard Interval 1/32, 1/16, 1/8, 1/4 Transmission mode 2K, 4K, 8K (FFT) ATSC Frequency range 50–860 MHz Input level -34 to +40dBmV Constellation 8-VSB Bandwidth 6MHz Key reference specification ATSC A/53 DVB-C Stanard J83.A(DVB-C,J83.B,J.83.C) Constellation (QAM) 16, 32, 64, 128, 256, 64/256 Bandwidth(MHz) 8,6 Symbol Rate (Mbaud) 5-7, 4.2-5.3 Multiplexing Maximum PID remapping 180 input per channelPID remapping by automatically or manuallyPSI/SI: SDI/PMT/TOT/PAT/BAT/CAT/TDT/NIT InsertAccurate PCR adjustingMax numbers: 4 or 8 mux for RF and 1 Mux for 1*MPTS ASI I/O DVB-ASI: 2 * ASI input and 2*ASI output, one for backup, 75Ω, BNC, 188BytesMPEG-2: TS over DVB-ASI (EN 50083-9)ASI Selectable out: mirror of one MPTS IP I/O RJ45 port: 100/1000M GbE Port,1*DATA port used for input and outputIP output: 1*MPTS & 127*SPTS UDP/RTPIP input: 128*MPTS/SPTS UDP/IPTS over UDP, unicast, and multicast streaming TS over IP ASI and IP output ASI Output 2 * ASI output, 75Ω, BNC, 188Bytes IP Output 1*MPTS & 127*SPTS UDP/RTP Modulation DVB-T Modulation Channel: DVB-T adjacent frequenciesModulation standard: EN300744Frequency range: 96~864MHz,1Khz one stepModulation standard: EN300744Bandwidth: 6M, 7M, 8MFFT mode: 2K, 8KConstellation:QPSK, 16QAM, 64QAMGuard Interval 1/4, 1/8, 1/16, 1/32FEC 1/2, 2/3, 3/4, 5/6, 7/8TS bit rate＜31 Mbit/s ATSC-T Modulation Channel: 8VSB adjacent frequenciesConstellation: 8VSBFrequency range: 96~864MHz, 1Khz one stepConstellation: 8VSBTS bit rate＜19 Mbit/sMER≥40 dB DVB-C Modulation Channel: DVB-C adjacent frequenciesFrequency range: 96~864MHz, 1Khz one stepMER ≥ 40 dBSymbol rate: 5~7 MbaudDVB-C standard DVB-C (J83.A, J83.B, J83.C)Constellation: J.83A-6/32/64/128/256QAM; J.83B-64/256QAM; J.83C-64/256QAMSymbol rate: J.83A-5 ~ 7MSymbol/s, J.83B - fixed; J.83C - fixedBandwidth: J.83A - 8M, J.83B - 6M, J.83C - 6M ISDB-T Modulaation Channel: ISDB-T frequencyFrequency range: 96~864MHz, 1Khz one stepISDB-T standard ARIB STD-B31Constellation: DQPSK, QPSK, 16QAM, 64QAMGuard Interval: 1/32, 1/16, 1/8, 1/4Transmission mode: 2K, 4K, 8KCode rate: 1/2, 3/4, 5/6, 7/8Bandwidth: 6MHzTS bit rate＜21 Mbit/sMER ≥ 40 dB DTMB Modulation Constellation: 4QAM, 16QAM, 32QAM, 64QAMCode rate: 0.4, 0.6, 0.8Guard Interval: 420, 595, 945 IONS GENERAL OPTION Management Connector: 1*RJ-45, 100/1000M Ethernet interface.Remote upgrade:via network Configuration interface: web browser ,NMS Physical and power Power Supply: 110 ~220V Consumption 18-20WOperational temperature: 0~50°CStorage temperature: -10~70°CHumidity: 10%-90%Dimension: 430mm(W)×460(D)mm×45mm(H)Weight: 4.5kg Application & Diagram Application & Diagram Insert More programs to existing coaxial system DIGICAST as leader manufacturer of Digital TV headend equipment, provide different products to meet various project application Widely used in Hotel,Hospital and DVB-T,DVB-C,ATSC,ISDB-T digital TV Broadcasting system
