Thanks to Eunbin for being the first in Korea to release a concert Blu-ray in high-quality 4K UHD,
it seems like Bingos have become computer experts. ^^
The reason I’m writing this is to inform you that, on a Mac, there's no way to play it unless you replace the ODD firmware with an unofficial custom firmware. The same goes for those using AMD Ryzen CPUs.
The reason why 4K UHD Blu-ray playback has become so difficult is due to the newly applied AACS 2.0.
This has unnecessarily complicated the playback process. Even though Blu-ray has already struggled
to gain popularity against OTT services, leaving only a market for drama enthusiasts, this has further shrunk the market.
In Intel’s case, they’ve already developed the necessary core technology for UHD Blu-ray playback,
called SGX, but judged it as a rarely used technology, so they decided to remove it from CPUs released starting with the 11th generation, which came out three years ago. However, Intel server CPUs still support SGX because it’s crucial for various server security features.
Macs and Ryzen CPUs have similar functions to SGX. The latest Intel CPUs also have such features.
If a software were to be developed that supports the AACS 2.0 standard using those features (instead of SGX) and is certified,
then UHD Blu-ray playback could be possible. For example, UHD Blu-ray players,
PS5, and Xbox support the AACS 2.0 standard without SGX. However, developing such software is challenging, and there are few who know how to do it, meaning it requires a lot of development cost.
If demand were high, companies might bear the costs and develop it, but in the general PC environment, demand is low, so there’s no financial incentive to do so.
The following is a summary of the correct and necessary information about AACS 2.0, after removing incorrect and unnecessary information provided by ChatGPT.
To support AACS 2.0 (Advanced Access Content System 2.0), several hardware and software requirements must be met.
AACS 2.0 is a content protection technology used in UHD Blu-rays
to prevent illegal copying and distribution. The following elements are required to support it:
UHD Blu-ray Drive To support AACS 2.0, you need a UHD Blu-ray drive. Regular Blu-ray drives cannot read UHD Blu-ray discs, so a dedicated UHD Blu-ray drive is essential.
The drive must meet the security requirements of AACS 2.0 to read protected content from the disc.
SGX (Software Guard Extensions) AACS 2.0 may require hardware security technology like Intel SGX to protect content. Intel SGX provides a secure memory space (enclave) within the processor, protecting critical data used for content protection from external access. SGX is supported on Intel’s 6th to 10th generation Core processors and is necessary for software that processes AACS 2.0 during UHD Blu-ray playback.
HDCP 2.2-Compatible Devices HDCP 2.2 is a high-resolution content protection technology required
when transmitting AACS 2.0 content. UHD Blu-ray content can only be output through connections that support
HDCP 2.2 and HDMI 2.0 or higher. You’ll also need a display (monitor/TV) and HDMI cable that support HDCP 2.2, or playback of UHD content may be restricted.
AACS 2.0-Supported Software To play UHD Blu-rays, you need playback software that supports AACS 2.0.
For example, software like PowerDVD Ultra supports AACS 2.0 and can securely play UHD Blu-ray disc content.
This software utilizes certified hardware and security components to decrypt and output protected content.
HEVC (H.265) Codec Support UHD Blu-rays use High-Efficiency Video Coding (HEVC or H.265) to compress video data.
To play this, you need a GPU or software decoder that supports the HEVC codec. Most modern GPUs support HEVC hardware decoding, providing efficient performance.
Modern CPU and GPU AACS 2.0's encryption and decryption processes require a high-performance CPU and GPU.
An Intel Core i5 or higher processor may be necessary. A GPU capable of handling UHD resolution video is also essential, such as NVIDIA GTX 10 series or later, or AMD Radeon RX series or later.
Operating System Software that supports AACS 2.0 generally operates on the latest versions of Windows 10 or higher. To maintain security, you need the latest OS and drivers, along with regular updates.
In summary, you need:
A UHD Blu-ray drive
Intel SGX-supported CPU
HDCP 2.2-supported display and HDMI
AACS 2.0-supported playback software
A GPU supporting the HEVC codec
All these requirements must be met for proper playback of UHD Blu-ray content protected by AACS 2.0.
첫댓글 빙고님! 마지막 요약 부분 캡쳐해서 포스트 링크랑 항께 트위터에 공유해도 될까요?

역시 빙고님! 😄
감사합니다^^

thanks…no wonder why I have brought a Buffalo UHD drive, but still can’t run the disc…I decide to give up after reading your summary on system requirements 😅
If your ODD is a Buffalo BRUHD-PU3-BK, you can install custom firmware for the LG BU40N to enable UHD playback. However, since there is a risk of damaging the ODD if something goes wrong, it's highly recommended to seek assistance from a professional.
Download The all you need firmware pack.zip and sdftool_flasher.zip from this link
https://forum.makemkv.com/forum/viewtopic.php?t=19634
, and use the firmware file HL-DT-ST-BD-RE_BU40N-1.03-NM00000-211810241934.bin.
Important note: First, install MakeMKV, remove any disc from the ODD, close the tray, and then run sdftool.
@bestlove thank you very much for your information 🙏🏻
@ChengHamic The following link is a site in Korean that explains the process of firmware replacement and ripping methods. You can use Chrome's translator to view the content in English. Check out the details at: https://life-is-happy.tistory.com/952

@ChengHamic Please note that using custom firmware may void your warranty, so be cautious of this before proceeding.
