[dvblast-devel] dvblast & remote CAM decoding

Hi Ahmed,

None of what you are describing has anything to do with the main question.
All I wanted to know was about sending the encrypted streams to a remote CI
CAM.

We know that I can decrypt the stream using TBS6928SE
<https://www.tbsdtv.com/products/tbs6928se-dvb-s2-tv-tuner-ci-pcie-card.html>
when
the tuner and CI CAM is coupled. dvblast handles that very well afaik.

I'm interested to see what Georgi Chorbadzhiyski (tsdecrypt author) has to
say about letting tsdecrypt interface directly with a standalone cam such
as the DD one.

Is this something that can technically be done?
