We are gradually moving to digital content. If in the past we wanted to play games or watch movies, we needed tapes or discs, now they can be downloaded or even used via the cloud. And Intel will contribute to that trend with its 11th and 12th generation Intel Core processors, making it impossible for modern PCs to handle Blu-ray discs at 4K resolution, as Intel has removed support for the technology. SGX (Software Guard Extensions) security technology.
This technical issue arises from the fact that Ultra HD Blu-ray discs require Digital Rights Management (DRM), which requires SGX to function. This is a feature that Intel introduced on the Skylake generation in 2016.
However, according to Intel’s datasheet for the Core 11 and 12 generations, SGX has been listed as a deprecated technology.
As a secure encryption technology, SGX is often targeted for testing by security researchers, who have discovered many vulnerabilities in SGX. Therefore, from a security perspective, removing SGX is a safer move for Intel.
Currently, most ordinary users are no longer interested in playing Blu-ray discs on PC, but nonetheless there will be a part of users who love using Ultra HD Blu-ray discs affected, for example. as avid film collectors.
