[dvblast-devel] DVB-S2 modulators

[Ibrahim Tachijian]

@Ahmed Ramze
In my use case I cannot user RF to fiber. I must send the transponder in
question using IP/UDP and convert it back to DVBS2.

@Metin Olgun
"IP Input Modulator" is exactly what Im looking for, but I havent found any
that seem good yet.
Im imaginig what Im looking for is something that is standalone where I can
go to the webinterface and input the following details:

1. IP Input Multicast Address
2. Output DVB-S2 frequency + symbol rate + polarisation

And then be good to go.
