<<< DW-TRANSLATOR 3G >>>

by Droid [X droid X]




Hi guys!

First some wishes.


I've been developing this project for many months... seems to me 6 or more....
but the idea is as old as digital SatTV

I've spent my own money for hardware to test the system,
I have spent much days and nights developing it, so, please, try to follow all my wishes.


So, remember... this software can't be used for illigal purposes...
I have written this not for formality...
if I know that smb does use it for illigal purposes... I WILL stop the project...
remeber it... because I don't want providers to loose their money, they provide jobs
for people and fun for us, so, I ask you to follow my wish.





Som tech info:


FEATURES:
________________


- Translating DWs via ICQ
- Two-Way communication with clients

- Stream encrypting with 64 bit key [DES]
- Fake ECMs protection

- Support for 15 clients simultaneously
- Data cache for 50 DWs

- ECM support for Viaccess System
- ECM support for Seca System (in development)

- ~300 bytes - request (ECM) of a client
- ~100 bytes - respond (DWs) of the server




THE IDEA:

What DW-TRANSLATOR is:


OK. First lets begin with explaining what DWs are. DWs (or DCWs) are Decrypted Words
used for decrypting video/audio stream. They are also called CSA-keys. To get DWs you
need to decrypt CWs (Crypted Words/Control Words) which are taken from ECM Stream. CWs
are decrypted by an OPkey which "lives" in a smart card and sometimes is updated by
provider.

CWs are usually updated 360 times per hour, i.e. once per 10 seconds. DWs are transmitted
from a smart card to receiver/CAM openly, so it is possible to intercept them and transfer
to other receivers. DW-TRANSLATOR Server (this application) is an emulator of a CAM
(Conditional Access Module), so it is possible to intercept DWs and forward them to
LAN/INTERNET etc. And at that end of LAN/INTERNET users can receive DWs by DW-TRANSLATOR
Client and watch their favorite TV channels and Radio stations.



"DW-TRANSLATOR 3G" - Why "3G"?


OK. This is a Third Generation DW-TRANSLATOR - "3G".
The first generation: DWs were transmitted using HTTP protocol to a WebSite. It was one-way
communication, so to watch a definite channel you needed to ask Server to set to the channel
you like and at that time Server could not work without being set on the computer with a
SatCard.

The second generation: DWs were transmitted using TCP protocol. From IP to IP.
It was two-ways communication that allows clients to watch any channel they like
from one provider. But this method was not safe for both server and client because
of having to use their real IPs. But from that time it became possible to use Server
on a computer without a SatCard.

The third generation: DWs are transmitted using ICQ. Yes, now it is possible to do
it via ICQ. It is safe and a server and a client are not in danger thanks to ICQ.
And it is two-ways communication that, as I said above, allows to watch different
channels at the same time from one provider using one original smart card.
And now there is no need for Server to have a SatCard on a computer.
