Help with ABS & DBS files
lazarus / 16-Databases

Hello all,

I have 2 files, one .abs and one .dbs from someone that has a video
receiver and wishes to have his company logo on the TV Screen instead
of some default value.

Now he extracted these two files from the device's memory and sent
them to me hoping I could help.

The extensions of the files led me to finding out that they can be
opened with softwares like MySQL, Absolut Database etc. (you can find
online the whole list) but I could not find one single piece of
software that can actually open them and let me find  the line
coresponding to the logo to overwrite it.

Here is the dropbox link to the two files : https://www.dropbox.com/sh

Can someone help me please?

Thank you,
Nick

Hello madref,

Is there anything I can do? Do you know of any way of removing the
password?

Anyone else please help! At least I want to know what I can use to
open the files.

At least the .ABS file is not a database file.
It contains a bootloader (look at it with a hex-editor).
It says: NCRCbootloader and DVBS2---0.1.0...2010-03-11

For more information
https://www.reddit.com/r/ReverseEngineering/comments/glr25/decompile_a
n_abs_file/

It's in binary form so you would have to find out where each segment
begins and what they mean.
An example can be found here

And even if you identify the place where the logos are (with
disassembling it), reassembling it with a different logo might prove
more difficult.

The .DBS is a NCRCdefaultdb file. I don't think this is standard
SQLite format.

I do think the .ABS contains logos and the .DBS only contains other
info like program and channel information.

Either way... I think you have better luck asking at a more specific
forum like http://www.sat-universe.com/ or a forum specific for that
receiver.

B.T.W. I used HxD hexeditor to view the files. (https://www.mh-
