Channel Code Copy of Compact Discs:
This project has the goal to archive the complete content of CDs on the channel code layer. Here, the NRZI signal which stems from the laser-pickup of a CD player is recorded directly, providing sort of a pit-land photo of the CD. The resulting image file, in turn, is demodulated and decoded in software, i.e. within a virtual CD player. The digital audio channel code on LaserDiscs and CD Video discs can be handled as well.

Note: The image extraction functionality requires a proprietary hardware interface with a modified disc player. Associated open hardware project "ccccd-HW": http://sourceforge.net/projects/ccccd-hw/

Note: Special restrictions apply. See disclaimers below and within the distribution.
