Yes it is, it is a licensed technology from NDS and the CAM is built into the 
mother board and can't be removed, you can put any smart card in ( it will 
fit) but it won't work, I would not try it.
If you wonder why to use DVB-S/C card instead of the regular TV card or TV 
card+MPEG encoder. The ability to save MPEG 2 directly from the Cable without 
A/D and D/A conversions in the way, also no CPU power needed, HOT and YES are 
transmitting MPEG2.

No, from what I understand the decryption is done in the CAM, the smart card 
hold the keys. 
The interface to a smart card is much too slow to do video decryption anyway 
and the smartcard computer is much too weak ( even in the best smart cards we 
are talking about 8086 style CPU power).

Other Cable and SAT boxes ( anything but NDS ) have a pcmcia slot, into this 
slot you fit the CAM and into the cam you put your smart card, it looks like 
a smart card to pcmcia adapter but it does much more.

No the CI interface is probably connected with some built-in CAM which is 
common in Germany. 
The CAM can also be built on the motherboard, but most people with their own 
SAT equipment preffer it to be a PCMCIA card so they can switch providers and 
boxes more easily.
The only people who insist on selling you "Trusted Computing" boxes are the 
NDS bunch.

It also does not mention NDS licensed technology, since NDS does not sell  
CAMs, you should make sure the Dreambox has an NDS CAM on it's mother board, 
or some way to do NDS decryption in software ( I very much doubt it ).
I sent an E-mail to the Dreambox  people but got no answer.
I think the target market is Germany, NDS is used by SKY in the UK, all over 
Israel, Direct TV in the US and some company in Italy. The EU regulations 
demand from the companies to sell CAMS, but NDS CAM was seen only in a site 
in Sweden written in Swedish, I do not know if it's on sale, or even if it 
will work.

Maybe the Sweden government have more power over it's market.
From my correspondence with DVB shop ( also in Germany) I understand that you 
need to buy a DVB-S or C ( SAT/Cable ) , an adapter to connect the CAM to the 
card, A CAM ( everything but NDS)  and your smartcard supplied by the 
Cable/SAT company.
