The '''Advanced Access Content System''' ('''AACS''') is a [[standardization|standard]] for [[content distribution]] and [[digital rights management]], intended to restrict access to and copying of the post-[[DVD]] generation of optical discs. The specification was publicly released in April 2005. and theThe standard has been adopted as the access restriction scheme for [[HD DVD]] and [[Blu-ray Disc]] (BD). It is developed by [[AACS LA|AACS Licensing Administrator, LLC]] (AACS LA), a [[consortium]] that includes [[The Walt Disney Company|Disney]], [[Intel]], [[Microsoft]], [[Panasonic Corporation|Panasonic]], [[Warner Bros.]], [[IBM]], [[Toshiba]] and [[Sony]]. AACS has been operating under an "interim agreement" since the final specification (including provisions for [[#Managed Copy|Managed Copy]]) has not yet been finalized.

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.
