4K Netflix Arrives On Windows 10, But Only Via Microsoft's Edge Browser (theverge.com)
An anonymous reader quotes a report from The Verge: Netflix 4K streaming is finally heading to Windows PCs this week. While a number of TVs and set-top-boxes already support 4K Netflix streams, the PC has largely been left out of the high-quality streams due to piracy fears. Netflix is now supporting 4K streaming through Microsoft's Edge browser, but you'll need a new PC to actually make use of it. Netflix is only supporting 7th generation (Kaby Lake) Intel Core processors, and there aren't many laptops that actually support both the 4K display required and the new Intel processors. As a result, Microsoft is using the 4K Netflix support as a marketing effort for its Edge browser and to encourage people to upgrade their hardware to watch new episodes of the Gilmore Girls. It all might seem like a bit of a con, but it's largely the fault of DRM requirements from Hollywood studios and TV networks. Content providers have strict controls for 4K playback, so that streams can't be captured and redistributed illegally. The latest hardware decryption features simply aren't available on older Intel processors, and the new Kaby Lake chips now support 10-bit HEVC, a popular 4K video codec.
4k looks night and day different on a 1080p monitor compared to a normal 1080p blueray. When downsampled, the picture looks more detailed.
There are some 4k nature demos on youtube, using chrome you can test multiple resolutions, 4k/2k/1080 on your monitor and test for yourself the difference.
4k sampled down, I can see higher detail in the water compared to a 2k resampled. Check out the Nature Relaxation channel to check out its demo videos, they are watermarked, but make great test videos.
I saw a video blog that said the reason that 4k on a 1080p looks so well, is the 4 pixel blocks downsampled are no longer sharing chroma, but each pixel is independent, so the higher detail. (I'm recalling from memory, so forgive me if I'm wrong).
I have a 2560x1400, and 4k looks great even it. So people who say you can see a difference, really need to try some of those 4k youtube videos on chrome.
Of course they can be decrypted in software. The fly in the ointment is that Netflix can't stream the movies and TV shows without Hollywood's approval. And Hollywood insists only on approving solutions on a hardware device basis. This is what delayed Netflix coming to Android. The software itself was easy enough, but Netflix had to get Hollywood's stamp of approval for every Android handset out there running the same software. That's why during the rollout, the Netflix app for Android was or wasn't available in Google's Play store depending on which phone or tablet you had.
So likely Hollywood is pulling the same shenanigans again, and only approved 4k Netflix streaming for Kaby Lake and the Edge browser at this time. Maybe they'll give approval for older processors and different browsers in the future. Maybe not. It's up to Hollywood - their content, their rules. If you don't like it, support independent artists and producers instead of the Hollywood establishment.
The problem is that if DRM stuff can hide its execution and memory contents, then malware can hide itself from debuggers and other means of developing countermeasures. SGX should not be a thing at all, in my opinion, in the same way that other crappy technology such as ActiveX shouldn't have ever been a thing. If enterprises are concerned about application security, then they should segregate it on a type 1 hypervisor.
