[dvblast-devel] DVB-S2 modulators

Sun Apr 17 03:07:06 CEST 2016

Hi again

there is too many brands are support ip input or SDI or ASI like newtec ,or datacom , but its not support to mix all udp/ips into one frequency thats need licence and additional boards wich its too much expensive like newtec MD6xxx series modulator.

the best solution its 

IP/UDP/RTP ===> IP mux ASI ====> DVB-S2 modultor ===> BUC/HPA sat (or directly to Reciver with out sat.)

we already did this with MVDS by sending video over internet and re-broadcasting it again.

>> I think there should be an IP input modulator.. Forex Newtec should have such a modulator.. But it is a professional one and costly solution. Your STB is only dvb-s? Cos there are IP STBs as well but if the requirement is to test dvb-s STBs then you certainly need a modulator, where modulator might not be enough.
