The Blu-ray disc standard requires that all pre-recorded discs be protected by copyright protection schemes. The copy protection used on a pre-recorded disc is only applicable to the stream file, not to any other file that forms the format(it means that only the m2ts and the ssif file be protected). Pre-recorded discs have several different levels of copy protection. AACS is a kind of encryption of the schemes. Today, we’ll show you how to remove encryption (AACS) from Blu-ray.
What is AACS encryption?
The first layer of the pre-recorded disc copy protection is AACS authorization management, development by advanced access content systems (AACS), the system consists of Disney, Intel, Microsoft, IBM, Toshiba, panasonic, warner bros and companies such as SONY.

AACS includes a system, according to the system, the key can be assigned to a specific players , if it make sure the key has been destroyed, the future will be “undo” blu-ray disc. When a newer blu-ray disc insert an old driver, the driver was asked to check on the disk “media key blocks” (MKB) version, if the new version of it than drive internal update, then can be copied to the permanent new MKB non-volatile memory. Therefore, playing the updated disc propagates the cancelled key list to all drives.
AACS was broken at the end of 2006 and many of the AACS decryption programs can be found on the Internet. However, the critical revocation system ensures that the AACS licensing and hacker communities continue to play cat and mouse games.
