Blu-Ray Ultra-HD DRM: Difference between revisions

Line 3:

Ultra HD Blu-Ray uses internet connected AACCS DRM requiring WiFi every time a disk is played, if AACS servers shut down disks become permanently unplayable .

The Ultra HD Blu-Ray standard incorporates various restrictions, making it impossible to play UHD Blu-Ray discs without proprietary software and an internet connection. The primary DRM system used is the Advanced Access Content System (AACS) for content distribution and digital rights management. It employs a set of cryptographically complex standards to encrypt and control media playback. Decryption keys can only be acquired by connecting via internet to the company's servers, meaning that if these servers were to shut down, the disks would become permanently unplayable.

== Hardware requirements ==

The requirements to play a UHD Blu-Ray on a PC are:

# A UHD-compatible optical drive certified by '''[[wikipedia:AACS_LA|AACS LA]].'''

# '''An Intel CPU with support for Intel Software Guard Extensions (SGX):''' SGX is a protocol that creates a secure environment to prevent users from tampering with imposed restrictions. This feature was available in Intel CPUs produced between 2015 and 2022 but was discontinued due to security concerns (list of vulnerabilities is available [[wikipedia:Software_Guard_Extensions#List_of_SGX_vulnerabilities|here]]).

# '''Intel Management Engine (ME)'''<ref>Intel ME</ref>''':''' If the ME version is outdated, the disc will not play.

# '''An Integrated Graphics Processing Unit (GPU):''' The GPU shares the SGX enclave with the CPU, reducing the likelihood of users accessing or copying audio/video data.

# '''HDCP 2.2 support:''' The integrated GPU, monitor, and HDMI/DisplayPort cable must all support HDCP 2.2. This protection system authenticates devices and encrypts the stream between them, making it extremely difficult to access audio/video data.
