Decoding Nagravision Using PC?
Sean
I've been looking at a very interesting site at
http://www.netzagent.com/freetv/ which gives software for decoding
Nagravision and Videocrypt using a PC. I'm specifically interested in
decoding Cine 5 at 42 degrees East which is encrypted in Syster and shows
live football on Saturday afternoons.
I've downloaded some of the software at this site but the readme files are
all in German :-(
I have a few general questions about this that I'm hoping that someone can
answer ( or failing that point me towards a URL where I can get an English
language FAQ ).
The questions are:
1. What type of video card is required to decode Nagravision? I have a
Voodoo 3 3000 and an 8mb ATI Xpert @ Play. Is there any software for these
cards?
2. How does the TV signal input to the video card? Do some of these cards
ship with an F-connector for a LNB input or do you simply hook up a
composite RGB output from your satellite receiver?
3. I assume that the picture is displayed on your computer monitor. Can I
hope to reach a 25 frames per second output with a PII 450 with 128Mb of
RAM. Are there any other factors in getting a good frame rate.
4. Sound to go with the picture would be nice ( not of huge importance as
the match commentary is in Turkish anyway ! ). Is any Soundblaster
compatible souncard okay for this?
5. I understand ( maybe mistakenly ) that algorhithms for decoding
Nagravison are known so its easier to decode than Videocrypt but has anyone
had any viewable Videocrypt output using this method ?
If anyone out there has managed to decode Nagravision (or videocrypt) then I
be keen to know what their hardware/software setup is.
I know that it's probably easier to hunt for C+ management keys to watch
footie on a Saturday ( I do this anyway :-) ) but this subject seems a lot
more interesting in itself and pisses people off less.
Any help appreciated.

Most BT848 capture cards will work (Hauppage, WinTV etc..) I am not sure about
your card though.

You have to have a capture card (a TV card or PCTV, as commonly known). Once you
have that you simply plug the coax into the card, just like normal TV.

Yes. I have an AMD K2-400 and the picture quality is surprisingly good. I use
MultDecrypt. I decodes Syster and Videocrypt (and even Eurocrypt a bit!)

Yes. It's slightly wobbly, but you can definitely see what's happening. The
colour is a bit rubbish though (depends on the program used), and the frame rate
depends on the speed of your computer. I can get something like 15 fps on
Videocrypt and 25 fps on Syster.

Processor AMD K2-400MHz, 64Mb RAM, PCTV card (Modular Technology), and bog
standard Matrox graphic card - 2Mb.

OK Just 4 More questions.
1. Does the software used (MultDecrypt or whatever) allow you to input the
frequency/polarity of the satellite channel?
2. Has anyone had any success with this kind of software and the various
digital encryption methods?
3. If so, will any BT848 card handle both anlogue and digital satellite
input?
4. I've got less than ?60 to spend on a capture card. What would be the card
of choice for maximum flexibility - Hauppage Primio ??
Again thanks for any suggestions.

Where can we find Multidecrypt?
A web site address would be *VERY WELCOME* :-))

The site says that this is 'Digital Only Free To Air' although the readme
file suggests that it decodes VC and nagravision. What are Hauppage digital
cards? Can they decode analogue signals as well ?

Yes and no. It does not allow you to input the SATELLITE frequency because you
have to take the signal from the satellite receiver!!! Just like the TV!! But it
does allow you to enter a VHF/UHF frequencies... just like a TV. It's all in
German though, so you'll have to get used to it first..

Well, the new version (http://freetv.future.easyspace.com/) says "Digital only
Free to air" whatever that means. I did not bother downloading it.... Try it.

That will cost you something like ё55 in a PC world. They come with the remote
control as well!

It's my honour, Sean! Hauppage "digital cards" as you call them are PCTV cards.
They just plug into one of the PCI slots and you connect your satellite receiver
to it. Basically, they are designed for watching the TV on your PC monitor. I
have no idea what they mean by "Digital only free to air" but it CAN decode
Syster and Videocrypt. And analogue signals is the only thing they can decode.

How should I configure the program to decode Videocrypt or does it work automatically. I am connected to Telia's cable net in Sweden, and I think they use Videocrypt...

Erm... To be honest I've never been to Sweden....

you do is use the pc to drive a serial interface
card that plugs into the card slot on a proper decoder, so you actually need
a complete satellite system that supports the
type of scrambling used. The serial interface card is slotted into the card
slot on the decoder and is connected by a cable
to a com port on the pc. Now you need some software to run on the pc and
this controls the serial interface and so it
descrambles the signal going through the decoder as the decoder thinks it
has a legitimate card in it.
A few years ago this was a common way of watching Sky for free, but
unfortunately this cannot be done now as far as I
know (if anyone knows differently, PLEASE PLEASE let me know asap).
I have never bothered with Nagravision, but the principle remains the same
using the pc to descramble it.
Hope this points you in the right direction.

Hum, no you do.
He is asking about PC/TV CARD software.
RF out from the Sat receiver to a PC TVCard. Then the PC software/CPU power.
is used to *reassemble* the scrambled PAL output.
Nothing at all to do with season interfacing.

"A little knowledge is a dangerous thing".
I suggest that you keep out of discussions that you are obviously totally
unqualified to join. Perhaps if you'd looked at some of the sites
referenced in thr thread you would have realized that the Nagravision
hack, and the only working VideoCrypt hack, are both entirely independent
of any "proper decoder", in that they apply a brute force DSP method to
find the cutpoints by examination of the video signal directly, and thus
decode it.

I suggest that your attitude leaves much to be desired. True, I had not
heard of
the decoding method that you are talking about, but of course not everyone
knows everything about everything as you obviously think YOU do and from
other "replies" I have read from you in the past you have little or no
tolerence
for people who do not know everything you know, or think you know.
In the future, before using your usual tone in your replies, consider that
many
people know a hell of a lot more than you do about some things, while you
may know more about other things.
As for being, as you put it, "totally unqualified to join" I may point out
that I
have been in the satellite business for many years, including the repair and
modification of satellite equipment, and manufacture of various gizmos, but
I NEVER try to put down people who do not know what I know, and if I
see someone has made an error I try to point it out without being a bloody
arrogant pratt!

Nevertheless, if you don't KNOW the answer, you ought not to be spreading
disinformation. There's enough erroneous data flying around this group
already, without adding to it.
The particular hack in question has been public knowledge for about three
years (perhaps more, I cannot remember for certain) and has been
mentioned here many times before.

All Brian was doing was pointing out that you had pointed people in
completely the wrong direction. The fact the you have chosen not to
apologise to the group for so doing but have gone on the offensive by
calling Brian an arrogant pratt makes words like pot, kettle and black
spring to mind.
