[dvblast-devel] dvblast & remote CAM decoding

[Daniel Kučera]

Ibrahim,

the question here is, if you can find dedicated CI device for PC - I
doubt DD supports arbitrary data input to the CI (but I might be
wrong).
I've found this http://www.bsc-bvba.be/linux/dvb/ but it's 10 years
old and unfinished.

Other way might be to use dedicated HW with proper IP input/output
cards and CI interface cards, e.g.:
