H.266/VVC Standard Finalized With ~50% Lower Size Compared To H.265
The Versatile Video Coding (VVC) standard is now firmed up as H.266 as the successor to H.265/HEVC.
[...] Fraunhofer won't be releasing H.266 encoding/decoding software until this autumn. It will be interesting to see meanwhile what open-source solutions materialize. Similarly, how H.266 ultimately stacks up against the royalty-free AV1.
Through a reduction of data requirements, H.266/VVC makes video transmission in mobile networks (where data capacity is limited) more efficient. For instance, the previous standard H.265/HEVC requires ca. 10 gigabytes of data to transmit a 90-min UHD video. With this new technology, only 5 gigabytes of data are required to achieve the same quality. Because H.266/VVC was developed with ultra-high-resolution video content in mind, the new standard is particularly beneficial when streaming 4K or 8K videos on a flat screen TV. Furthermore, H.266/VVC is ideal for all types of moving images: from high-resolution 360° video panoramas to screen sharing contents.
Versatile Video Coding (VVC/H.266):
In October 2015, the MPEG and VCEG formed the Joint Video Exploration Team (JVET) to evaluate available compression technologies and study the requirements for a next-generation video compression standard. The new algorithms should have 30-50% better compression rate for the same perceptual quality, with support for lossless and subjectively lossless compression. It should support resolutions from 4K to 16K as well as 360° videos. VVC should support YCbCr 4:4:4, 4:2:2 and 4:2:0 with 10 to 16 bits per component, BT.2100 wide color gamut and high dynamic range (HDR) of more than 16 stops (with peak brightness of 1000, 4000 and 10000 nits), auxiliary channels (for depth, transparency, etc.), variable and fractional frame rates from 0 to 120 Hz, scalable video coding for temporal (frame rate), spatial (resolution), SNR, color gamut and dynamic range differences, stereo/multiview coding, panoramic formats, and still picture coding. Encoding complexity of several times (up to ten times) that of HEVC is expected, depending on the quality of the encoding algorithm (which is outside the scope of the standard). The decoding complexity is expected to be about twice that of HEVC.

Personally, I always find the fact that I'm looking at a screen but the "noise" is coming from behind me a bit odd anyway.
It's not immersive - I can't turn and see the source of that noise, so my brain disconnects from the movie and hits reality again. The guy shooting ISN'T to my left... he's on the screen, or out of sight. And especially when the scenes change... that explosion was behind but now suddenly it's in front because the camera has cut. It's distorts the suspension of disbelief required.
I've not understood anything past stereo sound and even that I could happily just have mono and not care for movies and TV shows. Maybe for music, because you're already listening to an "imaginary" orchestra or whatever and a bit of separation helps.
But all these 8.2, sound bars, Dolby stuff... I never understood it, even in a cinema.
Slight stereo, so the guy on the left of the image is slightly left in the speaker. That's about all you need. And you don't have stuff going over or under because the effects rarely work except in a cinema. And, shush... don't tell anyone... but stereo is all you've got on your phone, etc. anyway.
It's also the cause of talking being drowned out under the music, and all kinds. Because it's so poorly downmixed and so reliant on you having a particular setup that most people just don't have.
There comes a point with every such technology where I just say "Why?" and stop following anything past that. Video - HD. Audio - Stereo. Dimensions: 2 (3 is fun but we can't make it work properly, though VR is getting very promising). Strangely, that's the common-denominator format for most devices in existence at the moment, and has been unchanged for a long time.
I'm honestly of the opinion that anything beyond that should be a "check this box to buy/download the 8.1 surround / 4K version" as an optional extra (whether free or not).

If you get a newer receiver, it will have speaker autodetection, several preset configurations to use, and an option to calibrate (which you'll need equipment for that probably doesn't come with). Autodetection works pretty damn well.
