FMUSER DTV4475 64-Channel IP QAM RF Modulator yog ib qho khoom siv tagnrho-hauv-ib qho uas ua haujlwm ntau ntau, sib tsoo, thiab hloov kho. Nrog 64 multiplexing channels, 64 scrambling channels, thiab 64 QAM modulating channels, cov cuab yeej no txhawb nqa mus txog 512 IP inputs los ntawm nws 6 cov ntaub ntawv chaw nres nkoj thiab tuaj yeem tso tawm mus txog 64 tus neeg nqa khoom tsis nyob ib sab (50MHz ~ 960MHz) los ntawm nws 2 RF tso zis interfaces.

 

Nws kuj muaj dual RF tso zis ports uas nthuav dav bandwidth rau QAM cov neeg nqa khoom. Lub modulator no muaj 6 GE inputs (4RJ45, 2SFP) thiab txhawb nqa mus txog 512 IP inputs dhau UDP / RTP, nrog rau qhov siab tshaj plaws ntawm 840Mbps thiab 512 IP inputs rau txhua GE inputs. Nws kuj txhawb PCR kho kom raug, CA PID filtering, PID remapping, thiab PSI / SI kho.

 

Nrog lub peev xwm los txhawb nqa txog 256 PID remapping ib channel, cov cuab yeej no kuj txhawb nqa DVB dav dav scrambling system (ETR289) thiab simulcrypt cov qauv ETSI101197 thiab ETSI103197.
