Then either the standard is wrong or you misread it since this seems not to
be the case. At least the software CI/CAM only sends the descrambler keys
to the DVB card and only needs the ECM PES as input, it never sees the
actual encrypted/decrypted data. I don't know which part of the DVB card
does the descrambling, but there seems to be some relation between the
descrambler and the streams setup to be demuxed as DMX_PES_VIDEO/AUDIO on a
full card.
I don't know if the Nova card has the descrambler hardware. Since there's a
Nova card with a CI interface now, at least this card should have the
descrambler. I don't know if that card supports feeding keys to the
descrambler through the driver (current or at all).
