Intel’s Dropping of SGX Prevents Ultra HD Blu-Ray Playback on PCs

Intel removed the security feature SGX from processors of the 11th and newer generations. Problem is, the feature is one of the requirements to play Ultra HD Blu-Ray discs on computer systems. From a report: The Ultra HD Blu-Ray format, often referred to as 4K Ultra HD or 4K Blu-Ray, supports 4K UHD playback with a pixel resolution of 3840x2160. One of the requirements for playback of Ultra HD Blu-Ray discs on PCs is that SGX is supported by the installed processor and by the motherboard firmware. The Blu-Ray Disc Association defined DRM requirements for Ultra HD Blu-Ray disc playback. Besides SGX, playback is protected by HDCP 2.2 and AACS 2.0, with some discs using AACS 2.1. Intel Software Guard Extensions (SGX) "allow user-level as well as operating system code to define private regions of memory, called enclaves, whose contents are protected and unable to be either read or saved by any process outside the enclave itself, including processes running at higher privilege levels" according to Wikipedia.
