Fraunhofer HHI is proud to present the new state-of-the-art in global video coding: H.266/VVC

After devoting several years to its research and standardization, Fraunhofer HHI (together with partners from industry including Apple, Ericsson, Intel, Huawei, Microsoft, Qualcomm, and Sony) is celebrating the release and official adoption of the new global video coding standard H.266/Versatile Video Coding (VVC). This new standard offers improved compression, which reduces data requirements by around 50% of the bit rate relative to the previous standard H.265/High Efficiency Video Coding (HEVC) without compromising visual quality. In other words, H.266/VVC offers faster video transmission for equal perceptual quality. Overall, H.266/VVC provides efficient transmission and storage of all video resolutions from SD to HD up to 4K and 8K, while supporting high dynamic range video and omnidirectional 360° video.

New video format 'halves data use of 4K and 8K TVs'

A new video-encoding technology that promises to cut data use by at least half has been announced, after three years of talks involving some of the tech industry's largest players.

In order to stream 8K video reliably, tests have indicated that homes would require internet connections capable of more than 85 megabits per second (Mbps), which is beyond what many properties have today. However, that has the potential to drop to a more manageable 40-50Mbps if H.266 takes off.

BBC got the facts wrong

VVC doesn't offer the same compression for all content (source)

Vieron added that royalty fees for IP were not always helpful to broadcasters and equipment vendors, not least when requests were made by some to sign NDA’s prior to knowing what the licence fee actually covered or involved.

“But these are new paradigms, and new ways of thinking,” stated Vieron, and one of these was to – in effect – start thinking with a clean sheet of paper and where Ateme was working on a concept where Artificial Intelligence was an integral part of the codec, and actively looked at the content, its target device and where there was “machine deep learning” in the codec. The potential, said Vieron, was between 30-60 percent compression gains in bandwidth. The gain in Sport would be smaller, but the benefit in movie transmission would be at the higher end of the target scale.

From Lee's article

Fraunhofer HHI announced it has finalized the H.266 codec, also known as Versatile Video Coding (VVC). The new compression standard is expected to reduce file sizes by up to 50 percent compared with H.265, in exchange for an increase in overall complexity and a need for more powerful encoding and decoding horsepower. It can also be used to support features like 8K HDR without requiring huge amounts of bandwidth or tons of hard drive space.

The tradeoff, of course, is that VVC is harder to encode and decode. According to tests performed by BBC R&D, encoding H.266 is 6.5x longer than HEVC, while decoding took 1.5x longer. HEVC isn’t exactly known for speed as it is, so a 6.5x impact on encoding is a significant hit.

More on Canon 8K camera (45MP), and additions to its family ...

Canon just trying to rush their product out. The Sharp micro 4/3's is way more consumer friendly as well as not being so heavy.

If you go look at this newcamera.com 8K camera page you see them all shown.

World First 8K M4/3 Mirrorless Camera Developed by SHARP, the prototype was displayed at CES event and according to SHARP representatives the camera will officially arrive at the end of 2019. It’s really interesting to see how this camera performs when we record 8K videos. And one of the most amazing thing is the Camera also carries built-in IS mechanism. I still remember Panasonic representatives told us they have removed IBIS from Panasonic GH5s camera due to heat dissipation issues. So, let’s hope for the best and Sharp new M4/3 8K solution will open new gateways for existing camera makers. BTW, they can do reverse engineering also to create their own iterations

Sony very clearly hinting us that upcoming camera have either 6K or 8K video recording options. And as we have published that Sony upcoming A7S III, Sony A7R IV and Sony A9 II camera will have 8K video recording capability. 8K video recording capability doesn’t mean you will get a 8k output, as we know the current line-up of Sony alpha fullframe and mirrorless camera uses 6K videos (Full sensor readout) to create 4K videos.

Per Panasonic

8K on Micro 4/3 is complicated, if not impossible.

Yeah the fact that Sharp has a flip around screen that allows you to see what you are shooting holding it as a selfe has amazing potential the other Camera makers are just incorporating 8K video into the same old large camera chassis. Nikon has a 8K one in the works and Olympus now sold had one also.

from the subscription free article ^ -

"…..Many fine papers have been presented at SMPTE conferences and are available on the SmpteConnect YouTube channel that shutter speed, shutter angle, blur, and other controls are available in post-production if you start with a 300 frames/sec 8K master. I think we can be fairly certain that there will be growth in 8K production in the coming years. This will drive down prices and require revisions to underlying SMPTE standards that allow the images to reach the consumers.

If we create more 8K upstream, then the post, mastering, and distribution world will start to see more 8K, which in turn will spread downward to the consumer in ever-increasing volumes. Nobody knows in which order this will take place, but having been to a lot of video conferences over the past couple of months of lockdown, I think it’s a safe bet to say that consumer 8K webcams to capture the details of your early-morning, precoffee face peeking over the collar of your pajamas is not likely to be a growth market just yet."

No problemo, the Canon 8K camera want to catch fire?, about a Samsung 8K TV, should it catch fire too?

SMPTE Periodical - Update from the Standards Vice President: UHD-2/8K

I remember seeing the first 8K images at IBC, and I was struck with feelings of awe, wonder, and incredulity in equal measure. The engineering marvel that I was witnessing—not just the display, but the entire ecosystem from glass to glass—was a wonder to behold. The sheer audacity of putting the system together made me proud to be in the industry. I was left with the question “Who wants this?”

Fast forward to summer 2020, and the world is very different. 4K is normal and we are bracing ourselves for the most spectacular 8K coverage that the world has ever seen, with the Olympic Games in Tokyo (which will hopefully occur in 2021) promise of a number of world-firsts, including live helicopter shots, longest sports coverage, new sports never seen before in 8K, and all available this year (or maybe next year when lockdown ends). Mix in the delight of an 8K opening ceremony with immersive audio and rich metadata, and I think it is safe to say that the future of broadcasting is within reach… or is it?

Despite advances in compression technology, 8K remains a bandwidth hog, and the re-engineering required to transform every terrestrial, satellite, cable, and over-the-top (OTT) network into 8K is unlikely to happen quickly. We are already starting to see national legal frameworks being modified to allow simultaneous streaming of events with a live broadcast to permit those with 8K I P capabilities to connect to a content delivery network (CDN) to experience its beauty.

We should not forget that 8K production followed by downsampling can bring benefits that are hard to achieve in any other way. One that excites me is the prospect of 8K, high dynamic range (HDR), high frame rate (HFR) capture that is then resampled in space and time, as well as cropped for traditional delivery. As a former springboard diver, the thought of finally being able to see Olympians grimace in super-duper slow motion as they struggle to land their 109b (i.e., 4½ somersaults in the pike position) knowing that I don’t have to follow them is a real joy.

These overscan techniques are not limited to sports though. Many fine papers have been presented at SMPTE conferences and are available on the SmpteConnect YouTube channel that shutter speed, shutter angle, blur, and other controls are available in post-production if you start with a 300 frames/sec 8K master. I think we can be fairly certain that there will be growth in 8K production in the coming years. This will drive down prices and require revisions to underlying SMPTE standards that allow the images to reach the consumers.

If we create more 8K upstream, then the post, mastering, and distribution world will start to see more 8K, which in turn will spread downward to the consumer in ever-increasing volumes. Nobody knows in which order this will take place, but having been to a lot of video conferences over the past couple of months of lockdown, I think it’s a safe bet to say that consumer 8K webcams to capture the details of your early-morning, precoffee face peeking over the collar of your pajamas is not likely to be a growth market just yet.

Lockdown is forcing our SMPTE standards meetings to go virtual. If 8K is your specialty or if you’ve always wondered what goes on in a standards meeting, then maybe now is the time to find out. Details of upcoming meetings are on the events page of smpte.org, and guests can participate by filling out an AG-15 guest participation form on the About/Policies page of our website. Don’t be shy; the worst that can happen is that you’ll discover that a lot of excitement can be generated by relatively few words in a relatively boring document in the middle of a relatively long meeting. The quality of SMPTE’s standards is recognized globally because of the attention to detail required to deliver stable platforms upon which innovative entrepreneurs and big businesses alike can deliver excellence.

Universal Display Corporation Announces Formation of OVJP Corporation to Advance the Commercialization of Groundbreaking OLED TV Manufacturing Technology

Names Jeff Hawthorne CEO of OVJP Corporation, 25+ Year Capital Equipment Industry Veteran


Universal Display Corporation (Nasdaq: OLED), enabling energy-efficient displays and lighting with its UniversalPHOLED technology and materials, today announced the formation of its wholly-owned subsidiary OVJP Corporation (OVJP Corp). To be headquartered in Silicon Valley, California, OVJP Corp was established to advance the commercialization of Universal Display’s (UDC) novel, mask-less, solvent-less, OLED printing manufacturing platform. This newly established subsidiary will be led by Jeff Hawthorne, who has been appointed Chief Executive Officer of OVJP Corp.


Organic Vapor Jet Printing (OVJP) is a groundbreaking dry direct printing technology for depositing organic materials to manufacture 4K and 8K resolution OLED TVs. This technology represents a high-throughput, high-performance, efficient, large-area patterned OLED manufacturing process platform and enables cost-effective printing of side-by-side red, green and blue (RGB) OLED TVs. OVJP technology originated at Princeton University with Professor Stephen Forrest and his research team under the long-term research program with UDC. The Company has made significant advancements through the years and is currently working on printing full-color phosphorescent RGB 4K test panels. OVJP research and development will continue in Ewing N.J., and OVJP Corp. will focus on scaling the technology into a commercial equipment system.


Jeff Hawthorne brings a wealth of technical, strategic and operational leadership expertise, and over 25 years of experience in the capital equipment industry, primarily at Photon Dynamics (PDI). Under his leadership, Photon successfully scaled its tools from Gen 4.5/5 to Gen 6, 7.5, 8 and to Gen 10 as panel makers broadened its manufacturing of displays from small/mid-size to large-size and PDI became the market leader of test and repair equipment for the global flat panel display market.


"The formation of OVJP Corporation is the next step in our strategic roadmap for commercializing our state-of-the-art OLED printing technology and we are pleased to have Jeff join us to lead our new subsidiary," said Steven V. Abramson, Universal Display's President and Chief Executive Officer. "UDC was founded with the mission to enable the OLED industry. We began with the idea of energy-efficient, high-performing phosphorescent OLED emissive technology and forged a path of discovery, development and delivery to now a broadening portfolio of commercial UniversalPHOLED materials. We are now taking the idea of dry printing OLED TVs in a vacuum environment and accelerating its commercial path. Jeff’s seasoned background and in-depth knowledge of the display capital equipment industry, from both the technical and operational aspects, will be valuable during this critical period as we further shape and evolve OVJP into the OLED market."


"I am excited to join OVJP Corporation and build on UDC’s technical innovation and momentum of this revolutionary manufacturing technology," said Jeff Hawthorne. "Universal Display’s leadership in the OLED industry and its outstanding history of successfully commercializing technology innovation is remarkable. OVJP has the tremendous potential to transform OLED TV manufacturing and further enable proliferation of OLEDs in the marketplace. I look forward to contributing to UDC and the OLED industry’s next stage of growth."

AUO ramping up 8K TV panel production

AU Optronics (AUO) has launched a series of 65- to 85-inch 8K bezel-less panels targeting the high-end TV segment, according to company sources.

The company has kicked off volume production of related 8K panels, which can also be used in advertising billboards and other smart display applications, said the sources.

The firm's 8K bezel-less TV panels feature a refresh rate of 120Hz with the brightness being able to ramp up to 1,200 nits.

Some industry observers pointed out that AUO has begun shipping its 8K TV panels to Samsung Electronics, enabling the Korean vendor to launch a series 8K TVs to cash in on increasing market demand for large-size, high-resolution TV models amid rising stay-at-home economy.

Samsung is expected to continue to strengthen its cooperation with AUO as it is withdrawing from LCD TV panel market, said the sources.
