Txheej txheem cej luam
DMB-24E multi-channels FTA tuner rau RF tshaj tawm transmodulator yog qhov siab ceev demodulating thiab hloov kho tag nrho hauv ib qho khoom siv digital headend uas muaj max 24 FTA tuner inputs los hloov mus rau 4 lossis 8 lossis 16 cov khoom thauj tsis nyob ib sab nrog multiplexing. Nws kuj txhawb 128 * MPTS / SPTS UDP / IP inputs thiab 1 * MPTS & 127 * SPTS UDP / RTP IP tso zis los ntawm DATA chaw nres nkoj thiab TS input rau re-mux los ntawm 2 ASI chaw nres nkoj.
Qhov no yog cov khoom siv tiam tshiab uas hloov RF cov kev pab cuam rau lwm tus qauv RF thiab IP TS uas yooj yim tswj los ntawm kev tswj xyuas lub vev xaib los pab xa tag nrho koj cov kev pab cuam rau koj lub zos RF system.
Nta:
Ntau yam tswv yim, saj zawg zog xaiv raws li lub teeb liab qhov chaw:
1: Mus txog 24 FTA tuners tswv yim
2: 2*Types Tuners+HDMI input -- Piv txwv li: 8 DVBS/S2+8*DVB-T/T2+8*HDMI

Ua haujlwm ntawm LCD Screen thiab Web Management---Yooj yim nyeem LCD xim pem hauv ntej vaj huam sib luag uas ua rau nws yooj yim rau kev teeb tsa thiab saib xyuas koj cov channel, tshawb xyuas cov khoom siv, thiab txheeb xyuas IP chaw nyob yam tsis muaj lub computer.
Daim Ntawv Thov Kev Tshaj Tawm Tshaj Tawm TV--- txhawb PCR kom raug thiab PCR ncua sij hawm kho, LCN (Logical Channel Number)
Multi RF Carriers tawm-4/8/16 DVB-T/ISDB-T/ATSC/DVB-C los yog 32 QAM DVB-C tawm kev xaiv raws li cov kev pab cuam raws kom muaj nuj nqis.
Daim ntawv thov
Ntxig IP qhov chaw, hloov kho RF qhov chaw rau txhua lub TVs tshaj qhov uas twb muaj lawm RF system
Kev tshaj tawm, kev saib xyuas, kev cob qhia thiab kev qhia ntawv thov
