Do we need it? I sure do for being full 8K bullet-proof into the future ...

And WHO knows what's coming up to replace Dolby Atmos. ...Dolby 8K Utmost?

Just so you know, there’s only one 8K HDMI port on the rear panel, and it’s limited to 40 Gbps, not the full 48 Gbps standard speed. There’s a dedicated thread that discussed this just a few days ago.

8K: The Next Big Thing in Home Entertainment

Life is good. You’re digging your big-screen Ultra HD TV, especially since you upgraded to a high dynamic range (HDR)-capable model that takes an already awesome picture and makes it even better. Add to that the expanding roster of 4K movies and TV shows you can stream or watch on disc and you’re all set. Which brings us to 8K, the next-generation TV format you’ve been hearing about — the one that delivers images four times more detailed than 4K. Sorry to rain on your parade, but as Chris Chinnock, executive director of the 8K Association (8KA), is quick to point out, 8K is about more than the 33 million pixels the format is capable of displaying: “For video-game producers and Hollywood directors, there will be so much more detail and realism that can be harnessed when telling visual stories. And as those stories are delivered to consumers, they will enjoy spectacular clarity, contrast, and color that will be possible only with 8K.” All reasons why Samsung, Sony, LG, and others have already embraced 8K and why Display Supply Chain Consultants (DSCC) thinks upwards of 20 million 8K TVs will be sold worldwide over the next few years. We caught up with Chinnock to get a handle on where things stand with the fledgling format and get his take on what 8K brings to the table today.

MediaTek's 8K-ready S900 chip is ready to hit smart TVs worldwide - NoteBookCheck.net 6/12/20

The S900 is MediaTek's newest SoC that is custom-designed for smart TVs. It is powered by ARM's Cortex A-73 cores, and is compatible with the HDMI 2.1A standard, allowing it to deliver 8K videos at 60 fps and 4K content at 120 fps. The chip also uses machine learning to improve picture quality in real-time.



MediaTek chips are quite commonplace among smart TVs. A company estimate speculates that about two billion smart TVs are running MediaTek hardware. We can expect to see a lot more MediaTek-powered TVs in the future as the company's 8K-ready S900 chip has hit the market.

The MediaTek S900 chip was unveiled last year in July alongside the MT6570. It has an unspecified number of ARM Cortex A-73 cores and a Mali G-52 GPU. It supports 8K video decoding and HDR10+ displays, along with HDMI 2.1A, which offers a maximum bandwidth of 48GB/s, allowing it to deliver 4K 120 fps and 8K 60 fps content. The chip also comes with MediaTek's proprietary AI PQ (AI Picture Quality) that leverages machine learning to improve image quality.

Although MediaTek hasn't named any OEMs yet, we should see the S900 quite often in the coming months. 8K TVs are still few and far between, primarily due to their sky-high prices and the general unavailability of 8K content.

Have no clue why they use HDMI 2.1A in this article...mistake?

XIMEA Releases 8K Industrial Camera Able to Stream 70 Fps to Production - PRweb.com 6/12/20

Super Slow Motion Jumping Water Balloon (Slo-mo video taken with XIMEA xiB-64 high speed camera) - YouTube

MUNSTER, GERMANY (PRWEB) JUNE 12, 2020
The well-known high-speed camera line from XIMEA called xiB-64 already includes fast models ranging from 1 Mpix at 3600 Fps to 16 Mpix at 300 Fps. The name of the new addition is CB654 and it offers 65 Megapixels at a remarkable data rate of 70 frames per second when streaming at 10 Bits of RAW image format.
CB654 is utilizing GMAX3265, the latest CMOS sensor from Gpixel which has picture parameters close to sCMOS performance. The 8K consists of 9344 x 7000 which is the world’s highest resolution sensor with Global shutter. The sCMOS level of picture quality is reflected in low noise and Dark current of 2e-/s that makes the cameras suitable for both industrial as well as demanding scientific applications.

There are various grades of GMAX3265 available and XIMEA is capable to supply multiple camera versions to provide different levels of quality and prices. For overall heat dissipation reduction and even better noise results, the cameras are equipped with a fan cooler which can be removed and replaced with a heatsink or water cooling system.

Such high grade sensor deserves an equally impressive interface and it finds this in the face of PCI Express Gen3 with the bandwidth of 64 Gbits and real data throughput of 7000 MB/s – or more than any other conventional industrial camera can compete with. This comes without the need for bulky and expensive frame grabbers or special software.

Then I'll wait next year for the next 8K generation Denon AV receivers with all 8K HDMI inputs (8) and outputs (3) with true real 48 Gbps. No sweat I can wait another year or so, I'm an adult.

* This is good enough for me right now...this 8K discussion thread. Google sent me directly right here.

Yesterday it was fun to read that 8K article from Sound&Vision (link supplied by HDTV1080P). Thx for that UHDTV4330P.

Also the 8K versus 4K article supplied by Penton; it's worth considering big time for all people with a display of say 75" and smaller.

But 8K is also much much more than that; it's like the big new cash register thing, and us as consumers we love encouraging the newest and latest technologies supplementing our deep visual passion...moving pictures in ultra high resolution with ultra high dynamic range and ultra fine pixels for best elimination of motion blur (blur-free).

Our eyes are the best judge second to objective scientific measurements by the best professional video tools in the business; price's no object sky's the limit go big or go home.

Stay safe, go 8K

I have seen the light, I've seen 8K @ video stores near me. You can call me mighty impressed...I knew right away.

Should I take pictures with my Android camera next time?

Now the question is: Would it be Panasonic 8K, Sony 8K, LG 8K, Samsung 8K, or other manufacturer 8K? Who's going to win the 8K race best moving picture contrast ratio wise? And what about 8K front projektors?

Will it be 8K UHDTV LCD LED, QLED, OLED or MicroLED?

Where will the consumer put his money on where his mouth is?
Will he eat lobster or fish&chips?

There is an 8K TV Association and certification logo so that consumers that see that logo on their 8K display will know they are purchasing a quality 8K display. It is disappointing that the 8K association of companies decided not to make the 3D feature mandatory. Hopefully around 10+ years from now the 16K association of companies will agree to make it mandatory for 16K displays to have some type of 3D feature (each company that makes 16K displays would decide rather to use active glasses, passive glasses, or glass free 3D technology if the 3D feature was made mandatory in 16K displays).

Getting back to the year 2020. According to the following article they are claiming that within 2 years a major streaming provider might start offering movies in native 8K quality. However, things can get delayed and it might be 3+ years before native movies are offered in 8K quality. Companies like Netflix have been using 8K digital cameras and are ideal for offering 8K movies. The existing HEVC codec is used for both the 2016 4K Ultra HD Blu-ray format and the new ATSC 3.0 over the air broadcast system. Bit rates for 4K Ultra HD Blu-ray discs peak at 128Mbps and ATSC 3.0 broadcasts peak at 57Mbps (ATSC 3.0 also has the capability of using 8K resolution with the HEVC codec) However better quality and more efficient video codecs might be created for streaming, satellite TV, cable TV, videogame systems, and possible even a new 8K optical disc format in 2026. However many articles when talking about 8K are only mentioning streaming, ATSC 3.0, satellite/cable TV channels, videogame systems, and no mention of a 8K optical disc format. But seeing a 8K DVD format with a legacy 480i DVD layer is a possibility or instead a 8K Blu-ray format or other 8K optical disc format that uses up to 2TB of storage with lossless video and audio would be a videophiles dream. 8K optical disc format would need to appear on the market by around 2026, and it would need to have better quality when compared to 8K streaming. If not then physical media would most likely slowly die as people with 4K Ultra HD Blu-ray discs switch to 8K steaming to get the best picture quality from 8K VUDU and 8K Netflix. But for 8K streaming to replace Blu-ray disc and all physical media, 8K streaming would need to also offer lossless audio.

Select quotes from the article:

“Our goal with the 8K Association Certified logo program is to offer a logo that consumers can look for knowing that any 8K TV that carries the logo will provide a high-quality 8K experience.”

“8K technology is about much more than 33 million pixels. Although the quantity of pixels is four times greater than 4K UHD resolution, the quality of those pixels and the dramatically better visual experience that can be delivered are the real benefit. “

“We believe that like 4K, streaming will lead the way with 8K adoption. The major streaming service providers are not offering an 8K service yet, but we see smaller players entering the market first, paving the way for the bigger players later. 8K will really take off when a major streamer offers a service, which will likely be within the next two years, in our opinion.”

“The standard codec for 8K today is HEVC (high-efficiency video coding), but AV1 is already being used on YouTube for 8K content and the MPEG-based codecs VVC (versatile video coding), EVC (essential video coding), and LCEVC (low complexity enhancement video coding) are all nearing finalization.”

Mister Lee, as you can see mister HDTV1080P relayed that article (link) yesterday.
He was the quickest; I was going to post that link only to see that he already have posted it, by 7 minutes sharp.

personally, I think you guys just need something new to talk about these days after tweaking the hell out of your players and 4K tvs, so 8K is it
for me, given the way grocery - https://forum.blu-ray.com/showthread...r#post16795407
prices are rising these days in times of Corona, I’ve got to save my money for food and a new 8K tv is simply out of the question

You have to look at this Murideo chart (see spoiler) to see how that limitation is applicable. Notice bandwidth uncompressed vs bandwidth compressed (DSC). Also the N/S (not supported). Uncompressed 12 bit is impacted.

Yes. Some pics would be nice.

[LordoftheRings]

I sure can do next time I visit and that they have their 8K TV on (last time it was off...due to pandemic).
My android has a 2 megapixel camera and HR setting (High Resolution). I think it's 720p (it's an old android phone...Motorola). I don't know how effective we'll be able to see the magnificent 8K picture from the 75" display but I'll try my best.

Robert can do that too @ his store from his cell phone camera.
And when he said that the 8K picture is awesome this is no baloney, it is indeed an upgrade over 4K...the contrast, the details in the tiger's hairs, the foliage looks 3D, and the colors are so realistic.
Some shots look spooky real 3D, better than 3D, much better.
But if 3D was presented in 8K with the full gamut of brightness and accurate colors it would be the best cinematic experience ever. Perhaps one day when the world is ready, the technology advanced enough.

But for now 8K beats 4K, and 3D too (1080p × 2 eyes). ...No contest, even from the best 4K OLED TV.
Purely visually speaking from my two eyes, I didn't take any measurements and I didn't play with the remote control video settings.

Robert has some 8K TVs @ his store, and some come with 8K video material on a loop.
Ask him how impressed he was. I know what he's going to say if he saw similar 8K video material as I did. Simply put you want an 8K TV and you want 8K video material shot natively in 8K. There are no two ways about it, seeing is believing and wanting. It's like sitting in your favorite sportscar and accelerating on curved scenic country roads, dancing with the stars. There's nothing else like it, it takes your entire body over and sprinkles it with rainbow fireworks of sensual sensoriel emotions.

Hey I didn't say it, I felt it just like I was there in the here and now.

[PaulGo]

For now and the next several years I don't think you will see live events in greater than 1080p HDR. After many years 4K movies are starting to be shown.

Like all new technology until a large quantity of 8K TVs are sold the justification for production of 8K movies will be minimal.

For the next few years the main selling point for 8K TVs will be better quality reproduction of 4K material on large size TVs.

[LordoftheRings]

I agree Paul, content is king. And here quality 8K content. Accessibility and productivity.
When? It's already here but only in very short supply, for now.

There's no rush to get an 8K TV; price's will come down and without enough 8K content we have some time ahead of us to enjoy 4K. Time is on our side.

But we can still discuss our 8K passion, dream of the future...It's permissible.
Passion is the cultivation of dream, satisfaction is reality.
It's not what we have, it's who we are...our dreams...in this 8K discussion thread.
We are keeping in touch with the latest developments; worldwide and forward and in our own backyards.

Google knows what we are searching for, what we read. They simply supply more of more our passions ... every day ... part of our technological vision, culture of cinema maison.

Any chance of the big dogs releasing "affordable" true 8k projectors in 2021? It's time to upgrade my JVC RS-25. If I can move into a $10k 8k projector....why not? At the very worst case I'll have a system giving me the best 4k sourced picture I can get.

Highly doubtful. The "push" is for displays not projectors. Has Texas Instruments even made an 8K DLP chip?

There sure is a lack of 8K projectors in the world today (late 2019), but that will change over the next couple of years. Look for the 2020 Olympics to be broadcast in Japan and other places in 8K! We’ve seen 8K demonstrations at trade shows. Digital Projection (a high end projector company) has shown a native 8K projector for over a year now. It is interesting in that it really is for 4K projectors in one to achieve “native 8K” and that is legit. JVC is now shipping a native 4K projector that will support 8K content, in the same fashion that many native 1080p projectors support 4K.

8K will be a major challenge for projector manufacturers. It means packing far higher pixel density into each chip/panel. For this reason, for the next few years, expect most 8K capable projectors to be pixel shifting 4K projectors, rather than native 8K. No matter. The promise of 8K on the screen is another game changer. There is no reason why you can’t sit four or 5 feet back from a 150 inch screen. Talk about full immersion! Unfortunately as of today, the least expensive 8K capable projector is still almost $20,000. That will change however. We could’ve said that about 4K just five years ago, and now 4K capable projectors are about to drop below $1000 for the most entry-level models.
