Ultra HDTV, HDMI 2.0, and HDCP 2.2 – Oh, What A Tangled Web We Weave…

A few days ago, I received an email from the president of an AV products manufacturer. He had purchased a Samsung UN65HU8550 65-inch Ultra HDTV back in 2014 and decided to take the plunge into Ultra HD Blu-ray.
Previously, he had been using an upscaling Blu-ray player to achieve 3840×2160 resolution, but now he wanted the real thing. So, he visited his local Best Buy and picked up Samsung’s UBD-K8550 UHD Blu-ray player, took it home, and connected it to one of the HDMI inputs on his UHDTV.
Sounds simple, right? Except that it didn’t work. The UHD disc spun up, started to play, and then a message was displayed that the player would down-convert to 1080p resolution because it didn’t detect support for HDCP 2.2 (the newest and most aggressive form of copy protection for optical disc media).
To him, this made no sense whatsoever. (Me, too!) Here he was, playing an Ultra HD Blu-ray disc, from a Samsung Ultra HD BD player, into a Samsung Ultra HDTV – and it wouldn’t work. I advised him to make sure he was truly using an HDMI 2.0 input (sometimes labeled as such, or color-coded).
He tried all of the inputs, including the MHL input that is supposed to be compliant with HDCP 2.2, but no luck. Again, the disc would spin up, and then display the same error message. (By the way, HDMI 1.3/1.4 inputs can also support HDCP 2.2.)
Another trip to Best Buy resulted in the purchase of Philips’ BDP7501 Ultra HD Blu-ray model, which was then connected to the Samsung TV and – voila! It worked, playing back in true 2160p resolution. That is; only when connected directly to the Samsung TV, and NOT through his existing Denon AVR (which likely doesn’t support HDCP 2.2 key exchanges on any of its HDMI ports).
Some quick checks on the Internet showed this wasn’t an isolated problem – others had purchased the same TV, or different screen size variations of it, and were unable to watch 4K movies from the Samsung player. One comment I read talked about going so far as to buy an HDCP 2.2 to HDCP 1.4 converter, a product I wasn’t even aware existed. And apparently, it worked! (Warning: This product may be illegal to purchase as it alters a copy-protection process. I’m only providing the URL as a reference.) (http://www.hdtvsupply.com/hdcp-2-2-to-hdcp-1-4-converter.html)
The next step was to check in with my friends at Samsung, who responded that an upgrade kit would fix the problem. It’s called the SEK3500U One Connect Evolution Kit, and attaches to your Samsung 4K TV through a separate connector on the side panel. This $400 box – which resembles a thin Blu-ray player – provides four HDMI 2.0 inputs, all up to speed with HDCP 2.2 support, HDMI 2.0a compatibility for high dynamic range playback, and improved color rendering, according to several Amazon reviews I read. (https://www.amazon.com/Samsung-SEK-3500U-ZA-Evolution-Kit) Samsung also commented that frame rates may play a part in the problem, as the Blu-ray Disc Association HDR specification for HDMI 2.0a calls for 2160p60 playback with 4:4:4 color, and that using a lower frame rate might fool the UHDTV into down-converting to 1080p resolution.
All of this just confirms my continued advice to my friends and colleagues: “Wait just a little bit longer before you buy a 4K TV.” Too many things are still in a state of flux on the manufacturing side, not the least of which is support for multiple high dynamic range formats. And the issues with HDCP 2.2 support are frankly, just ridiculous at this point: The standard’s been out for a few years, and it will be used exclusively with all HDMI inputs on Ultra HDTVs.
Another takeaway from this is the slow and steady move away from optical disc delivery of 4K movies and TV shows to streaming connections. The protocols for copy protection are a bit different for streaming, but at least the underlying architecture is standard across all platforms (some sort of common streaming protocol like RTSP, carrying MPEG4 H.264 or HEVC H.265 / VP9 with IP headers) and can be easily updated with software.
Given the continual increase in home broadband speeds – especially in metro areas – 4K streaming is fast becoming a realistic option. Granted, the image quality at 15 – 20 Mb/s won’t be as good as a file coming off an optical disc at 100 – 110 Mb/s, but as we’ve seen repeatedly, the vast majority of home viewers continue to choose convenience and price over quality. That may be one reason there are only three Ultra HD Blu-ray players on the market today: How many people are going to spend $300 – $400 – $500 for one?
As I write this, the SEK3500U is on its way, and my colleague will soon be enjoying true Ultra HD movies like he should have been from the start. I suppose the $400 cost is a small price to pay if you’ve already shelled out a few thousand dollars for an Ultra HDTV, but it would irk me to no end to be in that situation. (You know what they say about the “leading” edge often being the “bleeding” edge.)
To summarize; my advice to readers remains the same as it has been. If you are thinking of buying a new Ultra HDTV – like me – WAIT until next spring, or at least until Super Bowl time. Not only will you see lower prices, but you’re more likely to have all of the bugs out of the system – and you’ll be able to score a good deal on a set that can show high dynamic range content, too; certainly supporting two or more of the new HDR formats.
And if you just gotta have an Ultra HD Blu-ray player? Those prices will have come down, too. A quick check on Amazon shows the UBD-K8500 currently available for $317.99, while the Philips BDP7501 will cost you $279.99. (Panasonic’s DMP-UB900 player wasn’t shipping at the time this article was written.)
Samsung Moves Front & Center With HDR

Last Wednesday, I was one of a group of journalists, engineers, and other technical types sitting in on a presentation about high dynamic range (HDR) TV. The location was Samsung’s sparkling-new product showcase in lower Manhattan at 837 Washington Street, and the presenters ranged from Samsung execs to well-known industry consultants, including Florian Friedrich of AVTOP, Steve Panosian of Samsung, Kevin Miller from ISF, Gerard Catapano from Samsung QA Labs, and Jason Hartlove of Nanosys.
THE NEXT BIG THING
You’d have to be living under a rock not to have heard about high dynamic range television by now. Along with Ultra HD resolution, HDR is the next big thing in TV displays, along with a new, wider color gamut, and eventually high frame rate video.
The transition away from mature Full HD (1920×1080) display technology to Ultra HD is happening much faster than most people expected. The costs of manufacturing LCD panels for televisions have absolutely plummeted in the past couple of years; so much that there is at best a $50 to $100 price delta between same-size 1080p and 2160p TV models.
In fact, we will start to see major TV brands dropping 1080p models altogether in larger screen sizes; possibly as soon as December. Sales experience is showing that customers take the upgrade to 4K more often than not when buying sets measuring 55 inches or larger, which is good news for retailers.
And that’s “qualified” good news, as worldwide sales of televisions have been in decline the past four years. The double-digit annual growth of Ultra HDTV sales are keeping things from getting worse and leading everyone in Japan, Korea, and China to focus on 4K and leave increasing numbers of sales of 1080p sets to the bargain brands.
But quadrupling the picture resolution by itself isn’t enough to turn the tide. Hence, we now have HDR, which can produce images containing peak brightness levels that are 10x higher than what we used to see on our old tube HDTVs. (Remember those?) And the colors represented on these displays are also much more saturated and intense, thanks to advancements in illumination technology.
Back in the early days of high definition television, we were largely in unknown territory. The first HDTV broadcasts used terrestrial television, and everyone needed to learn more about antennas and set-top boxes. Yet, seven years after the first HDTV broadcasts, every major network had produced some quantity of HDTV content.
There were missteps. Remember the surge in interest in 3D about a decade ago? It peaked in 2009 and featured competing 3D encoding and viewing standards, expensive glasses that often broke, complaints of headaches and nausea after extended, and even a campaign by the American Academy of Ophthalmologists to test for eye disorders; one based on the inability of certain people to see stereoscopic images correctly.
TIME TO CHANGE THINGS UP
HDR is different. You don’t need anything other than the naked eye to see it, and the premise of HDR is that you are watching images with peak whites and contrast ratios that follow closely what you see in real life (about 14 stops of light at any instant, from deep shadows to peak brightness).
What’s more, the colors you see rendered in HDR are much more vivid than what our current televisions can display as they’re working with a restricted color gamut. If you’ve seen bright neon or LED signs at night, marveled at a brilliant sunset, or gotten up close to tropical flowers in bloom, you know how hard it is to reproduce those intense colors on a television or computer monitor.
That’s all changed. We’re now standing at the threshold of an entirely different class of displays that are advanced by several orders of magnitude from the color TVs your parents or grandparents watched 50 years ago. It isn’t just about having more pixels – it’s about adding in all of the visual elements that replicate what you see every day.
Samsung is one of the first companies to get out of the gate with HDR televisions, and they’re using a new technology to light up the screen. Instead of conventional white light-emitting diodes (LEDs) and arrays of color filters, the light source is made up of arrays of blue LEDs and matrices of green and red quantum dots (QDs). It’s not difficult to get intensely-saturated and bright blues from LEDs, but green and red provide more of a challenge. Hence; the QD backlight.
And they are bright. Samsung claims that their HDR TVs can achieve 1000 candelas per square meter (cd/m2) in a small area, which is quite the jump from the 300 cd/m2 or so that conventional white LED backlights can generate. Plus, the intense greens and reds generated by QDs have expanded the gamut of displayable colors considerably; closer to that of digital cinema projectors.
Now, the catch: How can we measure the performance of an HDR TV equipped with quantum dots? We can’t use the older test pattern generators and set-up Blu-ray discs as they’re limited to the current ITU Recommendation BT.709 color space and only use 8-bit color encoding. (HDR is based on a 10-bit color system.)
For that matter, we can’t even use the older display interfaces to connect a test pattern generator. For HDMI, the standard must be version 2.0a, and if we want to use DisplayPort, it must be version 1.4. It goes without saying that we must use an Ultra HD Blu-ray player if we want to source HDR test patterns from optical disc – and there is exactly one of those (Samsung) on the market, with another one coming from Panasonic this fall.
At the Samsung event, Friedrich and Miller explained how a new suite of test patterns has been prepared for Ultra HD Blu-ray to both evaluate and calibrate an HDR display. This test pattern UHD BD will be available from Samsung and can be used with any HDR TV, even the line-up of LG organic light-emitting diode (OLED) UHD sets that have come to market.
Steve Panosian talked about the lack of standards in TV performance and how there has to be a better way for consumers to compare the performance of one brand of HDR TVs against another. Although at this point in time, there are so few models available that it’s basically Samsung vs. LG, with companies like TCL and Hisense looking to get into the game this year.
Jason Hartlove from Nanosys made an appearance to talk about what’s happening with quantum dot science and what the next generation of HDR TVs might look like as the QD arrays in Ultra HDTVs start to resemble something like an OLED emitter array. And Chris Chinnock of Insight Media served as moderator for the day’s events, which culminated in hands-on sessions showing how to use the test pattern UHD Blu-ray to evaluate a set’s performance and calibrate it for optimal results.
The interesting thing about HDR TVs is that we really don’t need to provide much in the way of user adjustments anymore. HDR TVs use CEA 861.3 metadata, flowing through an HDMI or DisplayPort connection, to determine brightness levels, gamma, and color values. And with peak brightness values in the range of 800 – 1000 cd/m2, why would we need to have a “Dynamic” picture mode setting? (It’s already dynamic!)
Although I had seen this demonstration on two previous occasions, Insight Media and Samsung did an excellent job of explaining the challenges in both designing a set of test patterns to evaluate HDR TV performance and putting those patterns to actual use. I was reminded of those early days of HDTV: What signal format and connector do I need? What kind of antenna will pick up the broadcasts, and where do I aim it? What’s the difference between 720p, 1080i, and 1080p?
THE NEXT STEPS
My advice to everyone remains unchanged, however. If you are in the market for a new Ultra HDTV with HDR, I would hold off on purchasing it until at least January, if not next spring. By then, there should be several models supporting more than one HDR format (the baseline being HDR 10, but there are at least four others developed by Dolby, Technicolor, Samsung, and the BBC).
More importantly, your UHD set should support not only HDR content flowing through a display connection, but over an Internet connection. More and more content delivery is switching to video streaming as we move away from physical media. Plus, you’ll certainly spend less money on an HDR set if you can sit on your hands for a while, and there may even be a few more UHD Blu-ray player models to choose from six months from now, along with a lot more movies mastered in HDR.
As The World Turns: Vizio Is Acquired by LeEco

A press release crossed my desk yesterday, detailing how the TV brand Vizio had just been acquired by the Chinese firm LeEco for $2B. LeEco, while largely unknown on this side of the Pacific, is the 7th largest TV brand in China and also operates an online video content delivery business.
It’s expected that the combined operations of both companies will push them past Skyworth as the #6 worldwide TV brand, according to analysis from IHS Technology I just received this morning. (Never heard of Skyworth? Give it time.)
Vizio, which started operations over a decade ago, has become a powerhouse brand in the U.S. Although they don’t release their revenue and market share results, the company has given Samsung a run for their money over the years with a full line of televisions, most recently taking steps into HDR and UHDTV with Dolby Vision-equipped sets.
Yet, not everything the company has touched has turned to gold. There have been brief forays into smartphones (gone), tablets (gone), and computers (also gone.) In contrast, the company has done very well with sound bars, which all flat-screen TVs benefit from.
This news didn’t surprise me at all. The TV marketplace has become a very cutthroat business as prices and profits went into free fall, aided and abetted by competition from China where the nexus of LCD panel manufacturing is moving.
Numerous prominent nameplates have been victims of this downward trend, starting with Hitachi several years ago and continuing through Mitsubishi, Toshiba, and Sharp; all of whom have withdrawn from the North American TV market. (Hisense continues to sell televisions with the Sharp brand name in the U.S. and Canada.)
Panasonic, once a major player in TVs, is in the unusual position of offering an Ultra HD Blu-ray player (DMP-UBD900, $699) this fall, but no UHD televisions to bundle it with. For now, the company is not selling TVs at retail in the U.S. even though it demonstrated a 65-inch OLED UHDTV at CES that used an LG RGBW OLED panel.
Only Sony remains as a Japanese TV brand, and they’ve paid a dear price to stay in the game, losing hundreds of millions of dollars for a decade. Samsung and LG, meanwhile, have maintained their positions in the Top 5 even as worldwide TV shipments have gone into decline by an average of 3-4% per year, offset somewhat by double-digit growth in UHDTV shipments.
What’s interesting about LeEco is that, according to the HIS analysis, they’re willing to sell TVs at or below manufacturing costs – or even give them away free as a promotion – to secure paid subscriptions to their online content in China. That’s not a model that is likely to work here, but it does indicate how aggressive the new LeEco / Vizio marketing approach could be here and overseas.
Checking this weekend’s sales fliers, I spotted a Vizio 50-inch “smart” Ultra HDTV with HDR for $800 and a 70-inch model for about $2,000; both at Best Buy. Connect the dots and you can see why TV prices continue to fall, and why the bulk of TV sales are transitioning from 1080p to Ultra HD in a hurry.
Sharp (again, now made and marketed by Hisense) did Vizio one better this week, offering a 55-inch Ultra HD set for $650 (no HDR). We’re not far off from seeing $500 55-inch Ultra HDTVs, which will probably be on store shelves in time for the fall football season and certainly by Christmas.
Vizio’s conversion to a publicly-held company a year ago set the stage for this sale and is more proof of the shift in power to China for manufacturing and sales of televisions – at least worldwide. Will TCL and Hisense make further inroads to the U.S. market? What impact will they have (if any) on Vizio’s market share?
The Dog Days of Summer…and UHDTV

Ahhh, summertime: When everyone’s thoughts turn to cookouts, the beach, ice cream, baseball games, driving with the top down (or moon roof open), miniature golf – I could go on, but you get the idea.
One of the things most people are NOT thinking about is buying a new TV. Sure, there’s plenty to watch, but most of us would rather be outside in the nice weather. (Kayaking is my thing this time of year).
Even so, prices continue to drop across the board on all screen sizes, even on UHDTVs. Consider HH Gregg’s flier from last Sunday, where Sharp is now advertising its new line-up of discounted Ultra HDTVs for some eye-popping prices. How about $600 for the 43-inch LC43UB30 “smart” TV? Or $800 for the 50-inch LC50UB30? Both of those prices represent $200 discounts off full retail, which was already low.
There’s even a 55-inch model, the LC50UB30, for a grand. That’s Vizio territory when it comes to pricing and shows you how determined Sharp is to get back in the TV game and recapture some of the old magic from a decade ago.
Even the newest technologies are being discounted. Samsung’s HDR-ready S-series of UHDTVs are seeing substantial price cuts, with the 55-inch UN55JS8500 trimmed by $1,000 to $1998 and the 65-inch UH65JS8500 marked down to $2998. Curved models have seen an even bigger cut of $1500 off full book (UN55JS9000 is $2498 and UN65JS9000 is $3498).
Even LG’s new OLED TVs aren’t immune. The company ran a week-long promotion earlier this month with substantial discounts. The 55EG9600 was dropped to $5,500 from $6,000, while the 65EG9600 saw its price cut by a whopping $2,000 from $9,000 to $7,000.
And back around the 4th of July, their older 55EC9300 1080p OLED TV saw a price drop to $2,300. That price has since risen back to $2,500, which is quite a discount from when it first came out two years ago and was tagged at $15,000!
Don’t need a UHD set yet? Haier would be happy if you bought one of their new 50E3500 50-inch 1080p LCD TVs, and it will only set you back $370.00 – which works out to an amazing $7.40 per diagonal inch, a new low for LCD TVs. If 50 inches isn’t big enough, Haier’s got a 55-inch model (55E3500) for $400, which is almost as good a deal.
Given the number of UHDTVs that are now priced at or below $1,000, you can expect the shift from 1080p to 4K in larger TV screen sizes to accelerate. I had figured we’d see the majority of TVs 50 inches and larger move to 2160p resolution by the end of 2017. Now, I’m beginning to think it will happen even faster – maybe by the 4th quarter of next year.
Either way, there’s no question that your next TV purchase will bring you a lot more bang for the buck. With 43 inches now the most popular screen size, you’ll be able to buy two 1080p models at a time for what one cost a year ago. And the way things are trending, you may want to consider making the move to 4K if you are upgrading over the holidays.
For now, you can just enjoy swinging in your hammock with a nice cool glass of lemonade while the birds chirp, the bees buzz, and July turns into August. There will be plenty of time to ruminate on the features sets of new TVs this fall…
NAB In The Rear View Mirror

It’s been over a week since I got back from Las Vegas and edited all of my photos and videos. But once again, NAB scored big numbers with attendance and there were enough goodies to be found in all three exhibit halls, if you were willing to put in the time to pound the pavement. Over 100,000 folks made their way to the Las Vegas Convention Center to see endless demos of streaming, drones, 4K cameras and post-production, and H.265 encoders.
We were also treated to a rare haboob, or dust storm, which blew through town late Tuesday afternoon and blotted out the sun, leaving a fine dusting of sand particles on everything (and in everyone’s hair, ears, and eyes.) While most of the conferences and presentations tend to be somewhat predictable, the third day of the show featured the notorious John McAfee (yes, THAT John McAfee) as the keynote speaker at the NAB Technology Luncheon. Escorted by a security detail, McAfee walked up on stage and proceeded to warn everyone about the security risks inherent in loading apps onto phones and tablets. (Come to think of it, why does a flashlight app for my phone need permission to access my contact list and my camera?)
Some readers may remember the Streaming Video pavilion in the Central Hall at this show back in 1999. There, dozens of small start-up companies had booths showing how they could push 320×240-resolution video (“dancing postage stamps”) over 10 megabit and 100 megabit Ethernet connections, and not always reliably. (And not surprisingly, most of those companies were gone a year later.)
Today, companies like Harmonic, Elemental, Ericsson, Ateme, and the Fraunhofer Institute routinely demonstrate 4K (3840×2160) video through 1GigE networks at a data rate of 15 Mb/s, using 65-inch and 84-inch 4K video screens to demonstrate the picture quality. 4K file storage and editing “solutions” are everywhere, as are the first crop of reference-quality 4K displays using LCD and OLED technology.
In some ways, the NAB show resembles InfoComm. Many of the exhibitors at NAB have also set up shop at InfoComm, waiting for the pro AV channel to embrace digital video over IP networks. (It’ll happen, guys. Just be patient.) In the NAB world, video transport over IP using optical fiber backbones is quite the common occurrence, although it’s still a novelty to our world. (Haven’t you heard? Fiber is good for you!)
I spent three and a half days wandering around the aisles in a daze, but managed to find some gems among the crowds. Here were some highlights:
Blackmagic Design drew a crowd to see its Micro Cinema Camera, and it is indeed tiny. The sensor size is Super 16 (mm) and is capable of capturing 13 stops of light. RAW and Apple ProRes recording formats are native, and Blackmagic has also included an expansion port “…featuring PWM and S.Bus inputs for airplane remote control.” (Can you say “drone?”) And all of this for just $995…
RED’s booth showed the prototype of a new 8K (7680×4320) camera body that will capture video at 6K resolution from 1 to 100 frames per second. In 4K (3840×2160) mode, the Dragon can record footage as fast as 150 frames per second. (Both of these are in RAW mode.) Data transfer (writing speeds) was listed at 300 Mb/s, and the camera has built-in wireless connectivity.
Arri showed a 65mm digital camera, resurrecting a format that goes back to the 1950s. The actual resolution of the camera sensor is 5120×2880, or “5K” as Arri calls it. This sensor size is analogous to the old 6 cm x 6 cm box cameras made by Rollei and Yashica, and there is quite a bit of data flowing from this camera when it records! (Can you say “terabytes” of storage?”)
Drones dominated the show, with powerhouse DJI setting up in the central hall and an entire section of the rear south hall devoted to a drone “fly-off” competition. Nearby, a pavilion featured nothing but drones, cameras, accessories, and even wireless camera links such as Amimon’s Connex 5 GHz system. (You may recognize this as a variant of the company’s WHDI wireless HDMI product.)
Sony had side-by-side comparisons of standard dynamic range (SDR) and high dynamic range (HDR) footage using their new BVM-X300 30-inch HDR OLED display. This is the 3rd generation of OLED reference monitor products to come out of the Sony labs, and it’s a doozy with 4096×2160 resolution (3G-SDI Quad-link up to 4096 x 2160/48p/50p/60p) and coverage of the DCI P3 minimum color space. The monitor can also reproduce about 80% of the new BT.2020 color gamut. Peak brightness (scene to scene) is about 800 nits, and color reproduction is very accurate with respect to flesh tones and pastels.
Canon also took the wraps off a new reference monitor. The DP-V2410 4K reference display has 4096×2160 pixels of resolution (the DCI 4K standard) and uses an IPS LCD panel that is capable to showing high dynamic range (HDR), usually defined as at least 15 stops of light. It supports the ITU BT.2020 color space, can upscale 2K content to 4K, and will run off 24 volts DC for field use.
Panasonic unveiled their first laser-powered 3-chip DLP projector, and it’s a doozy. Using a short-throw lens, the Panasonic guys lit up a 10-foot diagonal screen with 12,000 lumens at WUXGA (1920×1200) resolution from the PT-RZ12KU. It uses a blue laser to excite a yellow-green color wheel and create white light, which is then refracted into red, green, and blue light for imaging. The projector weighs just 95 pounds, and the demo used an ultra-short-throw lens positioned about 12” – 16” in front of the screen.
Fine-pitch indoor and outdoor LED displays are a growing market. Both Leyard and Panasonic showed large LED displays with 1.6mm dot pitch, which isn’t much larger than what you would have found on a 768p-resolution plasma display from 15 years ago. The color quality and contrast on these displays was quite impressive and you have to stand pretty close to notice the pixel structure, unlike the more commonly-used 6mm and 10mm pitch for outdoor LED displays. Brightness on these displays is in the thousands of nits (talk about high-dynamic range!).
Speaking of HDR, Dolby had a demonstration in its booth of new UHDTVs from Vizio that incorporate Dolby’s version of high dynamic range. Vizio showed a prototype product a year ago at CES and it now appears close to delivery. The target brightness for peak white will be well over 1000 nits, but the challenge for any LCD panel is being able to show extremely low levels of gray – near black.
Vitec had what may be the world’s first portable HEVC H.265 encoder, the MGW Ace. Unlike most of the H.265 demos at the show, this product does everything in hardware with a dedicated H.265 compression chip (most likely from Broadcom). And it is small, at about ¾ of a rack wide. Inputs include 3G/SDI, composite video (yep, that’s still around), HDMI, and DVI, with support for embedded and serial digital audio. Two Ethernet ports complete the I/O complement.
Over in the NTT booth, a demonstration was being made of “the first H.265 HEVC encoder ever to perform 4K 4:2:2 encoding in real time.” I’m not sure if that was true, but it was a cool demo: NTT (a/k/a Nippon Telephone & Telegraph) researchers developed the NARA processor to reduce power consumption and save space over existing software/hardware based encoders. And it comes with extension interfaces to encode video with even higher resolution.
NHK was back again with their extension demo area of 8K acquisition, image processing, and broadcasting. (Yes, NHK IS broadcasting 8K in Tokyo, and has been doing so for a few years.) Among the cooler things in their booth was a 13-inch 8K OLED display – which almost seems like an oxymoron – and an impressive demonstration of 8K/60 and 8K/120 shooting and playback. On the 120Hz side of the screen, there was no blur whatsoever of footage taken during a soccer match.
This is just scratching the surface, and I’ll have more information during my annual “Future Trends” presentation at InfoComm in June. For now, I’ll let one of my colleagues sum up the show as being about “wireless 4K drones over IP.” (Okay, that’s a bit of a simplification…)
