'jazip' compression ?

Hello,

I have a firmware image from an oscilloscope from which I'd like to extract
the help texts to create a reference manual for our engineers. The firmware
seems to be compressed with a format called 'jzp' or 'jazip'.

Here is the header of the file :

00000000 69 6D 61 67 65 36 32 30 2E 6A 7A 70 43 50 00 02 image620.jzpCP..
00000010 00 00 00 18 EF 05 00 0A AF 02 4A 41 5A 49 50 00 ..........JAZIP.

00000050 E8 B0 F4 F9 A0 08 28 02 0B 20 97 C0 20 92 2B 84 ......(.. .. .+.

Does anybody know if this is a common and open compression format, and where
I could find a decompressor ? Are there any legal issues when doing these
kind of things with somebody's firmware images ?

Regards,

 

Oh bummer, I posted to the wrong group, sorry for that !
