The Blu-ray Disc standard mandates that all pre-recorded discs be protected by a copy-protection scheme. The copy protection used on pre-recorded discs is in practice only applied to the stream files and not to any other files that make up the format. There are several distinct levels of copy protection for pre-recorded discs. AACS is one of the encryptions. Today, we will show you how to remove the encryption (AACS) from Blu-ray.
What is AACS Encryption?
The first level of copy protection applied to pre-recorded discs is the Advanced Access Content System (AACS) developed by the AACS Licensing Administrator, a consortium of companies including Disney, Intel, Microsoft, Panasonic, Warner Bros., IBM, Toshiba and Sony. It is based on Advanced Encryption Standard (AES), a robust 128-bit key encryption system developed by the US government.
AACS includes a system by which the keys assigned to a particular player can be "revoked" for future Blu-ray disc releases if it is determined that those keys have been compromised. When a newer Blu-ray disc is inserted into an older drive, the drive is required to check the version of the "Media Key Block" (MKB) on the disc and, if it is newer than the one the drive has internally, to copy over to permanent non-volatile memory the newer MKB. Thus playing newer discs propagates the revoked key lists out to all drives.
AACS was broken beginning in late 2006, and numerous AACS decryption programs are available online. The key revocation system ensures, however, that the AACS licensing organization and the hacker community are constantly playing a cat-and-mouse game.
Removing AACS encryption from Blu-ray
Is it legall to remove Blu-ray AACS copy protection?
Although the removal of copy schemes from Blu-ray discs involves legal issues, however, many people believe that removing Blu-ray disc encryption is reasonable and lawful because they feel the "fair use" provision of copyright law should override any provisions against removing encryption. The good news is that in 2010, the US Librarian of Congress specified several exemptions from the anti-circumvention provision of the DMCA law. These are described as:
What you need：
* Reads DVD and Blu-ray discs
* Reads DVD-Video(VIDEO_TS.IFO) folder, Blu-ray(BDMV) folder and ISO files
* Reads Blu-ray discs protected with latest versions of AACS, BD+, MKB v61, MKB v62.
* Preserves all video and audio tracks, including HD audio
* Preserves chapters information
* Rip BD/DVD to lossless/uncompressed MKV container
* Fast conversion – converts as fast as your drive can read data.
* No additional software is required for conversion or decryption.
* Convert BD/DVD to MP4 wrapper with multiple subtitle/audio tracks.
* Add subtitles to BD/DVD and extract SRT subtitles from BD/DVD
* Rip Blu-ray/DVD to FLAC, WMA, MKV, MP3, etc audio files.
Start to Remove Blu-ray AACS and Backup Blu-ray losslessly
Step 1: Free download and install Blu-Ray Ripper. After that, launch the Blu-ray ripper and click “Load from disc” to load Blu-ray movie files
Step 2: Click on the drop-down list of “Format” to select output format, and if you want to remain the original quality and Blu-ray structure to full extent regardless of the output m2ts format, you can choose “Full Disk Copy” buttonto remove Blu-ray BD+ protections without any quality loss.
If you want to convert Blu-ray to lossless MKV, just choose to lossless MKV format.
Tip: Click “Settings” button to adjust audio and video parameters like codec name, aspect ratio, bit rate, frame rate, sample rate, and audio channels. (Notice that if you are using “Full Disk Copy” option, this function is unavailable.)
Step 3: Click “Convert” button to remove Blu-ray AACS protections. As long as the ripping work is finished by Pavtube ByteCopy, you can click “Open” button to get the output files that are without neither AACS nor BD+ copy protections.
You can put your Blu-ray rips to NAS or load them to USB hard drive then sream these Blu-ray movies on Vizio 4K TV,Sony Bravia TV, Samsung TV, etc. Or you can transfer Blur-ray to iTunes to playback via Apple TV, iPhone, iPad.
