AACS uses cryptography to control and restrict the use of digital media. It encrypts content under one or more title keys using the Advanced Encryption Standard (AES). Title keys are decrypted using a media key (encoded in a Media Key Block) and the Volume ID of the media (e.g., a physical serial number embedded on a pre-recorded disc).
While great care had been taken with AACS to ensure that content was encrypted along the entire path from the disc to the display device, it was discovered in July 2006 that a perfect copy of any still frame from a film could be captured from certain Blu-ray and HD DVD software players by using the Print Screen function of the Windows operating ...
The AACS Licensing Authority (LA) assigns a series of 253 unique cryptographic keys to device manufacturers. When an AACS protected disc is manufactured, a series of up to 64 keys called title keys are generated and the video content on the disc is encrypted using these keys.
But, in fact, that's not the case; AACS (Advanced Access Content System), one of the many copy protection standards being folded into high definition discs, is holding up both standards, and so ...
libdvdcss (or libdvdcss2 in some repositories) is a free and open-source software library for accessing and unscrambling DVDs encrypted with the Content Scramble System (CSS). libdvdcss is part of the VideoLAN project and is used by VLC media player and other DVD player software packages, such as Ogle, xine-based players, and MPlayer.
Just feed the small utility a crypto key (it comes bundled with keys for a few popular HD DVD titles, with the promise of more on the way), and it'll dump the video right off the disc onto your ...
In latest version of Adobe Premiere Elements 7 and Premiere Pro CS4 (both shipped in 2008), both source-video and video-export (to Blu-ray Disc) support H.264. Apple integrated H.264 support into Mac OS X v10.4 "Tiger" and QuickTime 7. The encoder conforms to Main Profile and the decoder supports Constrained Baseline and most of Main Profile. [1]
Components localization in the disc media. The Encrypted Title Keys are located in the Blu-ray and HD-DVDs where there is content to reproduce by the player with license. The information stored in the discs is found divided in three different parts: Reading/Writing area, read-only area and protected area.
