Goodbye, PC's UHD BD playback!? Reconfirmed the action environment.

"Ultra HD Blu-ray" (UHD BD) is an optical disc born in 2015, as a next-generation standard that exceeds the BD specification in terms of resolution, gamut and brightness.

Today, major online animation services such as Amazon and Netflix can also enjoy the same 4K resolution HDR images as UHD BD, while the rich image and sound quality brought by UHD BD's unique large capacity and high data rate is supported by core AV enthusiasts and collectors. Although the number is limited, UHD BD software, which includes new and old Hollywood films and domestic animation works, has also begun to be released.

In the corresponding products, UHD BD can be reproduced not only in AV devices such as recorders and players, but also in game consoles such as PlayStation 5 and Xbox Series X. The UHD BD player corresponding to the Dolby Vision/HDR10+ can also be purchased for about 20, 000 yen (Panasonic "DP-UB45"), it is not difficult to create a regenerative environment.

Among them, the one that cannot play UHD BD is "PC".

UHD BD regeneration on PC needs to clear several conditions such as OS, CPU, GPU, driver and so on, so it is very difficult to import, but because Intel, which makes CPU, has sorted out the security technology needed for regeneration, UHD BD regeneration cannot be carried out in the latest PC.

In the case of AV Watch readers, I think almost all of them are regenerated on AV machines, but there may also be people who combine high-performance HTPC to regenerate UHD BD. This time, the present situation and conditions of UHD BD regeneration in PC are rearranged.
