I just found that none of the AMD CPU actually support SGX
While AMD does not have SGX (its an sIntel Exclusive) it does have something similar called SEV
https://developer.amd.com/sev/
If you want to blame anyone for the fact that only sIntel processors are approved to play 4K UHD Blu-ray disks, its the Blu-ray forum. Its the Blu-ray forum (this I found out in a support e-mail from Cyberlink) that required sIntel's SGX for 4K UHD Blu-ray playback.
It will be up to the Blu-ray Forum to change the spec to allow something else to take over that functionality. IMO, calling themselves the "Blu-ray Forum" is somewhat of a misnomer, as they are really the
Blu-ray standards forum - I.e., the group that writes and sets standards that anyone wanting to support blu-ray is supposed to meet. (BTW - that link was not working for me, but that IS the official site).
IMO, the Blu-ray forum shot itself in the foot with this in two ways.
- They attached themselves to a vendor specific hardware standard (I.e., sIntel SGX)
- Plundervolt allows the extraction of cryptographic keys - meaning it can be exploited to make the CPU dump the protected UHD Blu-ray keys, and with those keys, one might be able to break the 4K UHD Blu-ray encryption, however, I have not heard of anyone successfully doing so.
SGX has turned out to have several severe issues and thus, it was in sIntel's best interests to drop it.
IMO, if the Blu-ray forum wants to sell more 4K UHD disks, they need to either drop this assinine requirement, or revise the standard to allow something else like TPM or AMDs SEV to take over that functionality. Otherwise, 4K UHD Blu-ray is dead on PC - and, BTW, I have a 4K UHD BR drive.
Not to mention that when this newest version gets cracked, (and it will), they'll change it again.
No one has broken it yet. I hope someone does as, IMO, it would be in the best interests of 4K UHD Blu-ray PC playback.
It's not for audio. Streaming is still lossy with DD+, whereas disks have lossless audio for great home theatre experience. I actually cannot believe that streaming platforms are still dragging their feet with lossy audio. Dolby True HD or DTS MA over streaming would need ~10 Mbps more only. Streamed 4K videos are also more compressed, with lower bit rates and lose some details in comparison to disks.
For those of us with FTTH, that's not a problem, but for those without an equivalently speedy ISP, it won't help them.
However, I wish more streaming services would support something better than DD+ AFAIK, few, if any, streaming services support even DD+ other than Netflix and Hulu.
