What technology is used for Blu-Ray protection?

DRM
AES Encryption
Blu-Ray protection technology
HDCP High Bandwidth Digital Content Protection

The correct answer is: HDCP High Bandwidth Digital Content Protection

The correct choice for the technology used for Blu-Ray protection is High Bandwidth Digital Content Protection (HDCP). HDCP is a form of digital copy protection designed to prevent the unauthorized copying of digital audio and video content as it travels across connections like HDMI or DisplayPort. This is particularly important for formats like Blu-Ray, which aim to safeguard high-definition content from being easily copied or redistributed. The other technologies mentioned serve different purposes. Digital Rights Management (DRM) is a broader category that encompasses various methods to control the use of copyrighted material, including audio and video but doesn't refer specifically to the technology used for Blu-Ray discs. AES encryption is a robust encryption standard used for securing data but is not exclusively tied to Blu-Ray protection measures itself. Blu-Ray protection technology, while descriptive, is not a specific term recognized in the same manner as HDCP and doesn't precisely denote the protective measures employed for Blu-Ray content. Thus, HDCP stands out as the technology implemented to secure Blu-Ray content during playback and transmission, ensuring that high-quality media is protected against unauthorized access.
