Analogue Nagravision (Syster) encoder

Mine is like this. It is because the heating parts are upside down in the enclosure.
 
I just got a Sagem G1 decoder from a friend of mine from Germany. The front "syster" led turns on, but does not decode neither in premiere-fa or ca mode. There are 2 entitlements on the card:
anfang ende programm
01-03-01 30-09-01 1
01-09-01 31-03-02 1
What am i doing wrong?
 
Hi,
I also have a G1 and am interested in any information to make it work.

Concerning Hacktv, version of Captain Jack, in the syster.c file of June 2020, there was the possibility of entering a specific personal key:

/*
* 64-bit decryption key.
*
* This key is used for supplied PIC hex file.
* This can be edited at internal EEPROM address 0x08 to 0x0F
* in the hex file and programmed back to PIC.
*
* If you know the key for your official card, put it here.
*
*/

Is this still possible in the current version and if so how?
Would it be possible to have an editor in graphical mode which allows to enter a personal key to generate a hex file for the PIC and better understand how it is built?

Thank you. Have a good evening.
 
You can use icprog to edit the PIC file at the addresses I mentioned above. Obviously, you need to edit the keys to match in syster.c

Re heating of PCB - yes, my Premiere decoder has exactly the same thing in its PSU section.

G1 - I have a few here and some work, some don't. As long as the receiver tunes into Syster program, it should work.

Look in syster.c at the top - lines 76 and 77. You need to edit the dates at the end of those to match your card's. Also, some Premiere cards look for data on a different set of VBI lines. You can adjust these on the same lines - the value after the date field. Currently set to 0 and works for most Premiere cards. I can't remember the exact offset for the other one but I think it's -3, so try that as well if changing the dates don't work.
 
Thanks, I have tried, but no luck yet, however there is a visible permutation change on the picture after the syster led turns on and the info tab disappears. So the box is trying to decode the picture.
 
Offset 0 must be ok. Only this value turns the syster led on, but can't get the decrypted picture with correctly reordered lines.

Thanks for your help. I didn't understand how addresses work. I tried with notepadqq, I get some addresses but I don't know if they are the right ones:
I don't know where to enter the characters in the two files. Sorry for so much ignorance

Hello, dear forum users, I have a decoder syster from NTV Plus, and I would like to know how to set it up so that it doesn't get locked.
 
Annoyingly, I never got NTV Syster decoders to work with hacktv. It's on my long list of things to fix. You can try it with
Code: 
--syster ntvfa
option and see if it kicks in...
 
This is a very cool thread!

I have a question: my efforts in searching eBay for old Nagravision encoders/decoders failed to show a single hit.

Maybe/hopefully I am just using the wrong search words. How did you guys find such gear?

I've already tried everything, and I've changed VBI to NTV+ in the syster.c file.
msg2[ 0] = 0x01; /* HTB+: 0x01 */
msg2[ 1] = 0x3A | ((s->flags >> 2) & 1); /* HTB+: 0x3A */
msg2[ 2] = 0x16; /* HTB+: 0x16 */
I think it needs to fit the key or tries to find it in the code line.In the syster.c file, modify the VBI code so that it can work with the specified operators.This is because the decoder cannot work with the customized VBI in the specified original file.

Currently, the decoder cannot work with the VBI implemented in the source file. It needs to be adapted to the --syster operator and must provide data for the VBI operator.

I think a good start might be the satelliteforums (also the smaller ones before they close).
You could ask there, they all have a tradecorner and old satellite enthousiasts often keep their old equipment. Good luck!

NTV Plus 2000 stereo receiver
NTV PLUS Decoder syster
bought on Avito (Russian service) for 450 rubles.

According to the owner, it was connected but not used.
 
Nothing... Not even on Google can I find a single image of a Canal+ or Premiere decoder.

Amazing how time flies and makes things disappear...
