hd2014 file format(hds)

Hi I want to build a led matrix like city TV with ws2812 led.I don't have any problem with hardware and micro software. I want a software to code data like pictures and videos. Hd2014 software is a suitable for this job, but I don't know how data coded in it! After a long time I understand how time save in time.hds, but I don't know ho data saved in default.hds file. I build a 16*8 project in hd2014 and type 'H' with red color in it. The code that software generated is:

Since it is a Digital Rights Management format is is probably encrypted and can't be used without a secret key. I think you should pick a different format.
