Re: CI/CAM support for offline (from file) decoding

Yes,  i  thought about that, but i need the Hardware CAM + CI, because
it's chip paired encryption. It means in my situation that the EMM and
ECM is also encrypted so it's hard to use in a SoftCam configuration.

I hope there's a solution in the DVB driver space.

I receive the signal via RF or IP. If via RF i think it can be decoded
via  the  HW,  and  the  record  it  to  disk,  but i need the full TS
decrypted, and i think it's not possible (to decrypt all the encrypted
ES  which  can be 20-30-40 in real time when i receive the signal). In
IP  configuration  it's also not possible. So i have the recorded full
TS  pieces  and somehow i have to decrypt with a CAM+Card paired to each
other.  Of  course  i know that the decryption is only possible if the
Smartcard  has  the  authorization in those date ranges when the files
was recorded. I have seen this kind of solution in Windows, but i need
it on Linux now.

Thank you,
