Title: Ntau-channel HD Encoding & Modulator
Qauv: DMB-9581E (7000)
1: Ntau yam teeb liab qhov chaw sib xyaw cov tswv yim----- customization rau ntau daim ntawv thov scenarios
Nws tuaj yeem yog 1: 4 / 8 / 12 / 16 / 20 / 24 * HDMI cov tswv yim +2 * ywj siab ASI+128* IP (SPTS / MPTS), muaj peev xwm ntawm multiplexing.
Los yog 2: HDMI + Tuner sib xyaw cov tswv yim rau kev xaiv: 16 HDMI+8* Tuner,
2: Cov zis: DATA1: IP tso zis tshaj RTMP/HTTP/RTSP/HLS/SRT raws tu qauv;
DATA2: IP tso zis dhau UDP/RTP raws tu qauv; 2 * ASI (kev ywj pheej)
IP input: DATA 3 RJ45 128*SPTS/MPTS UDP/RTP tawm
3: RF tawm nrog 8/16/24*RF DVB-T/ATSC-T/ISDB-T/Tb/DTMB los yog 12*/24 RF DVB-C raukev xaiv.(thaum ISDB-T RF tso zis tsuas yog 1 * ASI cov tswv yim, ISDB-T tso tawm tsuas yog 2K hom, tsis txhawb 4K thiab 8K)
4: Nruab nrog multiplexing module, muaj peev xwm multiplex cov kev pab cuam hauv zos nrog TS, IP
5: Nrog superior lub xub pwg nyom thiab modulation zoo MER Ntau dua los yog sib npaug rau 40dB
6: Txhawb kev siv hluav taws xob qis thiab kev ntseeg siab nrog MTBF (Lub Sijhawm Nruab Nrab Nruab Nrab) Ntau dua lossis sib npaug rau 50000 Teev
7: Tswj kev txhawb nqa web browser ntawm Ethernet interface
