Txheej txheem cej luam
DMB-9581E Encoder/Modulator yog ib qho khoom siv sib xyaw ua ke hauv ib qho (MPEG-4/AVC H.264), multiplexing thiab modulation functions nyob rau hauv ib tug qauv 1U rooj plaub.
Nws tuaj yeem hloov 8/12/16/20/24 HDMI signals, IP thiab 2 ASI input rau DVB-C/DVB-T/ISDB-T/ATSC
RF tawm nyob rau hauv ntau zaus ntawm 50 ~ 960MHz.Nws kuj yog txawm peem rau nrog 2 ASI ports thiab IP chaw nres nkoj rau tso zis TS.
Nta:
Encoder&Modulator&Multiplexer Txhua yam hauv ib qho ---tsis tsuas yog hdmi cov tswv yim, kuj txhawb 128 * MPTS / SPTS UDP / IP+2* ASI cov tswv yim, RF tawm tuaj yeem los ntawm HDMI, IP, ASI ib qho twg, IP tso zis 127 * SPTS tshaj IP (UDP / RTP), 1 / 8 * MPTS, 2 * ASI (kev ywj pheej) tawm, RF tawm nrog 4/8/16 * RF DVB-T / ATSC-T / ISDB-T / Tb / DTMB lossis 16/32 * RF DVB-C rau kev xaiv. (thaum ISDB-T RF tso zis tsuas yog 1 * ASI cov tswv yim, ISDB-T tso zis tsuas yog 2K hom, tsis txhawb 4K thiab 8K)
Tau tshaj ntau qhov chaw teeb liab ---Mixed HDMI + Tuner (DVB-SS2 / C / TT2 / ISDB-T / ATSC) input, piv txwv li 16 HDMI+8* Tuners (ntau zaus)
Siv tau yooj yim ntawm cov ntsiab lus zaus --bandwidth ntau 768 Mhz, zaus cov ntsiab lus tuaj yeem siv tau yooj yim hauv bandwidth ntau yam (thaum 16 * RF tawm)
Multi-Carriers Version xaiv---4/8/16 DVB-T/C/ATSC/ISDB-T tawm los yog 32 QAM DVB-C tawm kev xaiv raws li cov kev pab cuam raws kom muaj nuj nqis.
