Advanced Access Content System

<p>The Advanced Access Content System (AACS) is a <a href="/facts/Standardization/vS9AhNMS">standard</a> for <a href="/facts/Content_distribution/9gbe83sK">content distribution</a> and <a href="/facts/Digital_rights_management/4AF8JmDt">digital rights management</a>, intended to restrict access to and copying of the post-<a href="/facts/DVD/7fJsHJrN">DVD</a> generation of optical discs. The specification was publicly released in April 2005. The standard has been adopted as the access restriction scheme for <a href="/facts/HD_DVD/ULvpqYxb">HD DVD</a> and <a href="/facts/Blu-ray_Disc/zyPalhfG">Blu-ray Disc</a> (BD). It is developed by <a href="/facts/AACS_LA/gzLtD5xE">AACS Licensing Administrator, LLC</a> (AACS LA), a <a href="/facts/Consortium/uMGVbLps">consortium</a> that includes <a href="/facts/The_Walt_Disney_Company/R8kCbAVc">Disney</a>, <a href="/facts/Intel/SMF0gJJX">Intel</a>, <a href="/facts/Microsoft/nGIDDXdx">Microsoft</a>, <a href="/facts/Panasonic_Corporation/TqkBQmgj">Panasonic</a>, <a href="/facts/Warner_Bros./JRF3lhQ6">Warner Bros.</a>, <a href="/facts/IBM/QszA7nwd">IBM</a>, <a href="/facts/Toshiba/QHRaw8Tr">Toshiba</a> and <a href="/facts/Sony/7x4tCtBd">Sony</a>. AACS has been operating under an "interim agreement" since the final specification (including provisions for Managed Copy) has not yet been finalized.
</p><p>Since appearing in devices in 2006, several AACS decryption keys have been extracted from software players and published on the Internet, allowing decryption by unlicensed software.
