[dvblast-devel] DVB-S2 modulators

[Metin Olgun]

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.
