A DVB card (may) have a special connector for a CI interfase.
This is a card or 3 1/2" bay adapter to insert a CAM card into.
The CAM does the actual decryption or authorisation of the provider.
The smartcard is inserted into the CAM to provide the actuall
keys/subscritions for the decryption
The CAM always interfaces with the DVB card directly as the
decryption/authorisation is done in hardware.
For safety the authorisation data are never transfered on an open bus like

There are FF and budget DVB cards available with CI interface adapter
(e.g. Technotrend / Hauppauge).
You need one of both WITH CI adapter as a minimum.
The CI costs around 50€ for the Technotrend/Hauppauge cards and the CAM
is another 50..100€
This is costwise in between a plain (cheap) budget and a FF DVB card.

No chance here.
CI&CAM always interface directly with the DVB card (FF or budget), no
external (USB) solution is available.
So it's eigther a DVB+CI+CAM+Smartcard or smardcard reader (USB or serial)
+ software CAM [illegal !!!]
It's sad that there is no 'gray' softcam option that only does the CAM
opearations in software but needs the smartcard always. This would be
legaly a 'gray' area as it only violates patent regulations of the
decryption owner but would not circumvent the decryption. The 'banned'
plugin/patch combines this 'gray' CAM simulation with a fully illegal
'simulation' of the smardcard ;-)).
It's in this respect like the 'banned' CSS library which also contains
'illegal' CSS keys for DVD or just plainly breaks the encryption.
I belive for DVB there could be a legally acceptable version of a software
CAM when it does CAM simmulation only.
If the keys are always from the smartcard there would be no 'illegal'
For DVD this would only being possible if the CSS key of a 'legal' CSS
library would be legally licenced from the DVD forum. Unfortunely this
will (likely) never happen.
For DVB the keys are transferable on the smartcard and the smard card keys
are legally optained by the user when he subscribes at a program provider.
So using a software CAM which uses keys from a smartcard via a card reader
only violates patents of the decryption owner + program provider
regulations (which CI+CAM also violates already !), but it would not being
considered 'illegal' in europe.
The 'illegal' softcam can be stripped down to do just that (makes the use
ethically acceptable for me as a user), but the whole tool goes beyound
Unfortunely there may be some legal court fight neccessary to settle this
legally as the patent owners and providers may put up a fight first agains
whomever distributes the 'gray' CAM simulation.
So this option is also very likely not going to happen.
kind regards Peter
