Hi,

I have two TechnoTrend DVB-C PCI card and 1 CAM, is it possible to use this
CAM to descramble signal from frontends of both DVB card?

Thanks in advance for any reply!
Kurt

That isn't a very helpful answer to his problem, is it?
He might have wanted any reply, but trying to be friendly wouldn't have 
killed you.

I'll give this a go:

There is a way, called "cardsharing", to decode multiple streams with 1 cam.
Do note, however, that some people think this is illegal, but that's 
because cardsharing has a bad name. There are people who perform this 
"cardsharing" with other people over the internet, which IS illegal.

Because of this most people don't want us to talk about *any *kind of 
cardsharing, just to be on the safe side.
I can follow their reasoning but it still resembles some kind of 
illogical censor which we should not tollerate!
But I digress ...

Because this local cardsharing is not illegal (at least not where I'm 
from), some set top boxes you buy in the store also have multiple 
(working) tuners, so they perform some kind of internal cardsharing as well.

Please correct me if I'm wrong or being ignorant ...

CAM != CardReader

Getting control words outside the "secured" area is illegal.

It's not a matter of cardsharing. It's of course technicaly possible to have 
one cam beeing feed with streams from different tuners, but not on most PC 
DVB cards like the TT ones where CI is wired to the card.

Done.

What is the definition of this "secured" area?

According to you it's perfectly ok to decrypt multiple streams with one 
cam... but only if it is with the correct, approved, hardware?

In essence, this is a shortcomming of the TT hardware, can we really 
tell people not to fix it using software because it'll break some 
ridiculous IP law, or whatever?

Ridiculous law is still law.
A law doesn't say what is ridiculous and what is not, what is good and what is 
bad. It just says what a human community allow or disallow, at a given time.

Thanks Jelle, and Christophe, thanks for your reply. I was thinking in a
technical (developer's) way, but didn't mean to start an illegal issue...
Anyway I know the answer now, thanks
