[dvblast-devel] dvblast & remote CAM decoding

Wed May 30 11:57:24 CEST 2018

Hello Daniel,

I believe sending arbitrary data to the CI is the whole point of the "stand
alone CI CAM".
Somebody wrote a plugin to it for VDR,
https://github.com/jasmin-j/vdr-plugin-ddci2

I'd like to stay away from expensive HW solutions and rather pay for the
development of software.
