FMUSER DTV4427 16-Channel IP QAM RF Modulator yog ntau yam khoom siv rau CATV tshaj tawm xov xwm.
Nws muaj 16 multiplexing channels, 16 scrambling channels, thiab 16 QAM modulating channels. Nrog kev txhawb nqa txog li 512 IP inputs ntawm 3 GE chaw nres nkoj thiab mus txog 16 tus neeg nqa khoom uas tsis nyob ib sab (50MHz ~ 960MHz) tso tawm los ntawm RF tso zis interface, qhov modulator no muaj kev sib koom ua ke, ua haujlwm siab, thiab siv tau zoo.
Nws txhawb PCR kho kom raug, CA filtering, PID remapping, thiab PSI / SI kho, nrog rau 180 PIDS remapping ib channel. Lub modulator kuj txhawb DVB general scrambling system (ETR289) thiab Simulcrypt cov qauv ETSI 101 197 thiab ETSI 103 197. Nws outputs 16 uas tsis nyob ib sab QAM nqa khoom raws li DVB-C (EN 300 429) thiab ITU-T J.83 A/B , nrog kev txhawb nqa rau RS (204,188) encoding. Kev tswj hwm yog ib qho yooj yim nrog nws lub vev xaib kev tswj hwm lub vev xaib, ua rau cov cuab yeej no yog qhov kev xaiv zoo tshaj plaws rau CATV tshaj tawm xov xwm.
