[dvblast-devel] DVB-S2 modulators

[Ibrahim Tachijian]

Here's a more detailed example of what I'm trying to do:

1. Use DVBLasts "-d" parameter to stream an entire transponder to an IPv4
address
2. Have some kind of DVB-S2 modulator device (either stand alone or pci-e)
read this UDP/TS stream created by DVBLast and convert it back into DVB-S2.

In case you want the reason behind doing this;

Location A has a Satellite dish and a server with dvb-s2 tuner connected
using dvblast
Location B has no Satellite dish but requires a live-feed of one
transponder for testing Set top boxes.
