In this article, we will show you what is the Blu-ray copy protecction and how to remove the copy protection, so that you can watch the Blu-ray movies on any of your devices and media players as you like.
What is Blu-ray copy protection?
Commercial pre-recorded Blu-ray discs are typically protected with some form of copy protection. These encryption mechanisms restrict people where to play the Blu-ray discs and prevent people from extract the movie from the physical disc. Below part aims to instruct people how these copy protection schemes work and what kind of legal rights consumers may have.
Advanced Access Content System (AACS) is the first level of copy protection applied to pre-recorded discs, 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.
BD+ is a second level of copy protection that is optional for pre-recorded Blu-ray discs. After the stream files are encrypted using AACS encryption, they are further mangled randomly with instructions on how to repair the mangled files stored on the disc as special BD+ instructions. These instructions run in something called a “BD+ virtual machine”, special software that Blu-ray players are required to include. The virtual machine on the player runs the BD+ code on the disc and retrieves something called the “Fix-up Table” (FUT) to repair all the BD+ mangled regions on the disc.
BD+ was broken in 2008 by reverse-engineering the BD+ virtual machine. Each new BD+ Blu-ray disc release brings new twists in the virtual machine programs, each of which are again reverse-engineered by the hacker community. Just as with AACS, BD+ has become a cat-and-mouse game.
Region Codes are pieces of data that are embedded into Blu-Ray Discs to act as a restriction. This data, or region code, is read by the player and if it doesn’t recognize the region code as compatible or local, the disc will not play. Since region codes are specific to certain geographical locations, a disc can typically only be read and played by a Blu-Ray Player that was manufactured or intended for use in that same specific region. In total, there are 3 separate Blu-Ray region codes. These codes are classified alphabetically as Region A, Region B, and Region C. The following is guide map of Blu-ray region codes. This map shows the different Blu-ray codes and which areas they are utilized in.
- Region A: This region covers all of North America, South America and South East Asia.
- Region B: This encompasses Europe, Africa, Middle East, French territories and Greenland.
- Region C: Region which covers the rest of the world including Russia, Asia, and China.
