Everything You Want to Know About Blu-ray Ripping/Copying

Summary: Do you want to backup Blu-rays, rip Blu-ray to MP4/MKV or just copy Blu-ray to digital file? Here, you can learn any skills of Blu-ray ripping/copying.

Ripping Blu-Ray videos is not as straightforward as doing so with DVD videos, especially for starters. But never mind, there are always some guides that can instruct you to get Blu-ray rips or MP4/MKV extracts. To save your time to searching for the Blu-ray ripping/copying tips, here we have gathered around some top and effective tutorial on Blu-ray backing up. Hope you can find what you want in the corresponding categories.

Blu-ray Encryption

The main reason that you can't play your Blu-ray movies on your Blu-ray Player or some multimedia players is the encryption schemes. 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 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.

BD+ Protection

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.

Cinavia Protection

Cinavia, developed by a company called Verance, is a newer level of copy protection that is optional on Blu-ray discs. The system involves "steganography" or watermarking, in which a special encrypted data signal is hidden within a single audio channel in an audio track. Verance claims the Cinavia signal is inaudible, and that the signal can survive audio compression and recompression.

When a player with Cinavia support detects a Cinavia signal on a Blu-ray disc, it can verify whether playback should be allowed. The player can display one of four possible messages known as "Cinavia message codes". The most commonly viewed messages are (1) "Playback Stopped" and (3) "Audio Muted". Message (1) is supposed to stop distribution of "camcorder" recordings of first-run movies from theaters if the theaters include a Cinavia signal in the movie soundtrack. Message (3) is supposed to stop unencrypted ripped copies of movies. There is apparently no exception for consumer backup copies.

Region codes

Region codes are basically DRM (digital rights management) techniques that allow studios to control the release of films in various regions. A Blu-ray player only can play the Blu-ray discs sold at the same region as the Blu-ray player manufactured.

There are 3 separate Blu-Ray region codes. These codes are classified alphabetically as Region A, Region B, and Region C.

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.

When you want to play Blu-ray of region A, B and C on your Blu-ray player freely or on your region-locked PS3/PS4/Xbox One/360, you can refer to the following guides:
