3. CSS Decryption Reference
CSS (DVD-Video): Contents Scrambling System is the copy protection mechanism for DVD-Video. It uses a weak 40-bit proprietary encryption algorithm instead of a stronger public-key algorithm. It was designed to comply with strict US government crypto-export regulations. Even if the encryption were stronger--and DVD hardware players that plug into televisions and software players downloaded to a PC--all have their own unique key that unlocks the encryption key on the DVD. Each DVD has 400 copies of the same decryption key, each encrypted with every unlock code needed for each player. If one unlock key is compromised, every DVD can be decrypted

What's MPEG

MPEG (pronounced M-peg), which stands for Moving Picture Experts Group, is the nickname given to a family of International Standards used for coding audio-visual information in a digital compressed format. The MPEG family of standards includes MPEG-1, MPEG-2 and MPEG-4, formally known as ISO/IEC-11172, ISO/IEC-13818 and ISO/IEC-14496.
MPEG is originally the name given to the group of experts that developed these standards. Established in 1988, the MPEG working group (formally known as ISO/IEC JTC1/SC29/WG11) is part of JTC1, the Joint ISO/IEC Technical Committee on Information Technology. The convener of the MPEG group is Leonardo Chiariglione aka the father of MPEG.

The National Academy of Television Arts and Sciences (NATAS) awarded its 1995-1996 Engineering Emmy for Outstanding Achievement in Technological Development to ISO/IEC for the development of the MPEG and JPEG standards. The convener of MPEG made this statement about MPEG receiving the Emmy Award.
