Sharp has announced its next-generation ultra-large display featuring an 8K resolution, advanced backlighting with 2048 local dimming zones, and an HDMI 2.1 input. Given its dimensions, the Sharp 8M-B120C is designed primarily for commercial applications, but users with large homes and deep pockets can certainly use it for gaming and home entertainment. 

The Sharp 8M-B120C is based on a 120-inch UV2A II LCD (presumably IPS/IGZO) panel featuring a 7680×4320 resolution, 600 nits typical brightness (i.e. peak brightness in HDR mode is considerably higher), a 3500:1 contrast ratio, a 6 ms GtG response time, an up to 120 Hz refresh rate (albeit only for 4K content), and 176 degree / 176 degree horizontal / vertical viewing angles. The display uses a direct LED backlight featuring 2048 LEDs for enhanced contrasts. Given the display’s vast dimensions and power consumption, the unit is rated for up to 16 hours of continuous operation. 

Sharp says that the 8M-B120C monitor can reproduce 1.07 billion colors and is designed to cover a significant portion of the ITU-R BT.2020 color gamut. Meanwhile, to make the colors look more vivid, the 8M-B120C has a little better representation of red than defined by the BT.2020, according to the company. The display supports HDR technologies, such as HLG. 

Being the first company to release its 8K display over five years ago, Sharp has been gradually improving its panels featuring a 7680×4320 resolution as well as displays and televisions. When compared to predecessors, the Sharp 8M-B120C supports a higher typical brightness (600 nits vs. 400 nits), a faster response time (6 ms vs. 8 ms), and an HDMI 2.1 input that will make the unit compatible with upcoming consoles, players, and other equipment.

While the Sharp 8M-B120C is not a television, it does support the company’s super resolution technology used on the company’s Aquos 8K TVs that upconverts content to the panel’s native resolution as well as enhancing its quality. Furthermore, the display can also playback music and video files. 

As far as connectivity is concerned, the Sharp 8M-B120C is equipped with an HDMI 2.1 input which supports 4Kp120 and 8Kp60 formats over a single cable, four HDMI ports, a D-Sub (VGA) connector for a PC, and a 3.5-mm stereo audio input. The device also has a 100 Mbps Ethernet as well as two USB 3.0 ports. 

Premium video quality offered by the Sharp 8M-B-120C is accompanied by a Dolby Audio-badged audio subsystem featuring four 10-W speakers as well as two 15-W speakers. The LCD also has analogue and optical audio outputs. 

Featuring a 120-inch diagonal size, the Sharp 8M-B120C is enormously large and measures 107 x 32 x 78 inches (2717 × 805 × 1979 mm). It is also heavy: it weighs 454 Pounds about 206 KG with it stand. 

Sharp plans to start taking orders on its 8M-B120C display in late September and at least initially will make them to order. Recommended pricing of the product has not been announced, but we are certainly dealing with a premium LCD that will be priced accordingly.

Google’s Movie Service, Google Play Movies, Now Offers Movies in 4K and HDR10+ in 117 countries. Samsung is a launch partner but additional platforms will follow.

Google Play Movies Now Offers Movies in HDR, HDR10+ and Dolby Vision.
Google Play Movies now offers movies in HDR, HDR10+ and Dolby Vision..

HDR10+ MOVIES:
As promised at CES 2020, Google now offers movies in HDR10+, the dynamic metadata HDR format developed mainly by Samsung. Google also recently added support for Dolby Vision, meaning that some of its movies are available in a total of three HDR flavors.

Some of Google’s first titles in HDR10+ include The Joker, Aquaman, Wonder Woman, Shazam, and Crazy Rich Asians. Additional titles will be added over time.

Samsung is a launch partner and it was confirmed that Google’s HDR10+ titles will be made available on “other additional platforms in the future as well”

“The HDR10+ service is now available on Samsung Smart TV in 117 countries including North America, Europe and Korea,” said Samsung. “Users can now enjoy high-resolution HDR10+ 4K HDR content on the Google Play Movies.”

The Joker is now available in HDR10, HDR10+ and in Dolby Vision on Google Play Movies...
The Joker is now available in HDR10, HDR10+ & Dolby Vision on Google Play Movies.

HDR10+ STILL STRUGGLING:
In 2017, Samsung, Panasonic and 20th Century Fox formed the HDR10+ alliance but HDR10+ has been struggling to build momentum against Dolby’s HDR format, Dolby Vision, which is more widely adopted.

Panasonic now supports Dolby Vision in addition to HDR10+ in its TVs while 20th Century Fox has been swallowed by Disney who has seemingly abandoned HDR10+ for Fox titles. Samsung is the sole holdout.

Google’s launch cannot be seen as a win for HDR10+ either as the company is also offering content in Dolby’s HDR. Samsung said that there are now 108 HDR10+ partners worldwide, although only a handful of these are consumer-facing companies. The company added that it remains committed to the format.

8K is Making Progress Bit by Bit

Date: November 12, 2019

Written by: Thierry Fautier

It happened first at IFA 2019, Europe’s largest consumer tech conference in Berlin. 8K was everywhere. At IBC2019, expectations for 8K technology demonstrations were high. Since almost every TV maker around the world has announced 8K TV production. Many have even replaced their 4K TV offer with 8K.

As 2019 comes to a close, 8K continues to show strong interest, but what are the potential hurdles to overcome before mainstream adoption? We still don’t have enough information on next-generation MPEG codec or on Versatile Video Coding (VVC) licensing. And are we certain that VVC is the right option?

Phase 1: the demonstrations for future tech in today’s world

There is real-world proof that encoding for 8K is possible today. Here’s a rundown on some demos that showcase the possibility of 8K video:

  • The live BT sports demo: This was a collaborative effort. From Amsterdam, multiple partners came together to deliver one hour of live broadcast in 8K showcasing the Gallagher Premiership Rugby 7s tournament. It proved that 8K can be produced and transmitted live from the stadium to the studios.
  • Harmonic’s IBC2019 8K TV demo: This showed the next step from stadium to screen. With VVC, we can reach 8K resolution with close to 50% bit rate reduction over the popular High-Efficiency Video Coding (HEVC), but that’s not all. Harmonic was also live streaming using content-aware encoding (CAE) technology to provide different bit rates and resolutions from a KPN data center to the IBC Future Zone over a private line. We used updated firmware on a Samsung TV to decode the stream based on the DASH.JS player. The content of an equestrian show jumping contest that leads to an average of 14 m/s using CAE. This represented a world first.  We can now measure the true potential of CAE and see how TV sets convert up to 8K. Today, NHK is transmitting live at 85 Mbps via satellite and using the compression techniques developed three years ago and it provides a less than optimal result. The Harmonic demo validates that CAE efficiency depends on content complexity. Even at 39 Mbps, we are still more than 50% lower than HEVC in production at NHK. This matches what VVC promises in 2022, proving that we can use today’s technology to deliver tomorrow’s content, and without burning the budget.

Phase 2: 8K adoption is starting, and it’s exciting

8K is now being delivered with technology that was developed almost three years ago, which explains the 85 Mbps figures. We are now entering the second phase. Operators want more affordable bit rates, with a goal to come close to what is currently used for 4K OTT streaming (a 25 Mbps connection is required for Netflix in HDR). We have demonstrated that it is now possible with a range of 14 Mbps to 39 Mbps, without any optimization done for 8K, using cloud-powered encoding and CAE technology.

2019 was the 8K pre-game. There are more 8K TVs being made, and sales are predicted to pick up in 2020. This is especially the case in countries where 8K will be available. Tomorrow’s 8K streaming experience on connected TVs is in the starting block and waiting for the go-ahead to launch at full speed. 2020 is just around the corner and the games are about to begin. And we mean the actual games. The 2020 Tokyo games are expected to be the first large-scale 8K content ever produced. Will you be watching?

The HDTV is Officially Dead.

Date: 27 Feb 2020
Written by: Yoeri Geutskens

In barely seven years, 4K TV has evolved from high-end niche product to not just mainstream proposition but in fact to the low end of the TV market. On its way it’s pushed HDTV out of the market, meanwhile it’s been put under pressure already by the advent of 8K TV. The Resolution Gap was already big; now the chasm is gaping. The overlap has reduced to almost zero. How so? There are several resolutions used in broadcast television: 480p (SD), 720p, 1080i (HD) and 1080p (Full HD). Yes, 4K Ultra HD broadcasts exist but they cover well under 1% of all programs available. Meanwhile in TV hardware, we’ve got two resolutions you can choose from in 2020: 4K and 8K. Most major TV brands have phased out HDTVs, which until last year covered the low end of the market, where margins are low.

ONE OF THE FIRST 4K TVS – THE $24.999 2012 SONY BRAVIA XBR-84X900

4K TV now fulfills that role. That may sound surprising, because 4K ijs relatively new. The first 4K model, the Sony XBR-84X900, was introduced about seven years ago, at the end of 2012, at a price level of $24.999. Now you can buy one at $249.99! That’s a price erosion of 99% over a 7-year stretch, or close to 50% annually. That’s how steep the price erosion is in this business. No wonder even major electronics firms have difficulty competing and remaining profitable, and quite a few have divested their TV operations to license their brand name to leaner manufacturers. Granted, that entry-level $249 TV is a just 43-inch in size – a substantially smaller model than the 84-inch model Sony debuted back then. It’s also a second-tier brand – Insignia. But it uses the same display panel technology (edge-lit LCD), it’s got the exact same number of pixels, and in some ways it’s more advanced. It’s got HDMI 2.0 instead of v1.4 (which could not handle HDCP 2.2 copy protection that most source devices demand, or 4K input at frame rates higher than 30 fps); it can handle HDR signals, even if its peak brightness is not great. It’s got built-in streaming functionality and comes with a range of apps for all sorts of video services. And if size does matter, you can now get a 75-inch 4K TV for well under one grand – one twenty-fifth or just 4% of what you had to pay at introduction.

2019 $249 UHD TV

FAST EVOLUTION FOR HARDWARE:
It may also come as a shock that in this short period of time, 4K has evolved from the very high end of TV to the mainstream and low end of the market. Low end you say? Yes, for a number of brands, such as Sony, the most basic models are now 4K and HD has been dropped from the range. Samsung has confirmed only a single HDTV in its 2020 range – a 32” version of The Frame, their high design models, which by definition are not low end and likely have some margin left in them. LG confirmed they will not have any new Full HD or HD-Ready TV models in 2020. Panasonic would not confirm their plans for this year but so far it seems they have no new HDTV models on offer. At the same time, 4K is moving away from the high end: This year, one year after 8K TVs commercially debuted on the market with models you could actually buy – as opposed to the prototypes we’ve been shown at CES and IFA for years – Samsung has announced it will no longer offer its most premium display features on 4K models; it reserves those for its 8K QLED TV range. 8K now represents the high end, 4K the mainstream and low end. Meanwhile, TV broadcasting has a hard time catching up, because there’s no business model that offers them any incentive to upgrade. They’ll need to replace their entire production workflow, which is expensive and something they normally do once every seven to ten years. However, even when they start producing in 4K, it’s likely too costly to distribute it in that resolution. That’s because bandwidth is scarce, especially with terrestrial broadcast, but even with DTH (direct-to-home) satellite and cable/IPTV spectrum is limited, and a 4K channel simply takes the same capacity as four HD channels, unless you overly compress it, but that would defy the whole point of Ultra HD. Meanwhile 4K doesn’t bring any additional revenues. Advertisers aren’t paying more money to advertise on 4K TV channels, and the extent to which operators can charge more for these channels is limited. As a result, for 4K content we’re dependent on streaming platforms, for which bandwidth is not an issue, at least not their issue. It’s ironic perhaps that while the overall amount of bandwidth available to us increases year over year, the bandwidth for traditional broadcasting does not, and in many cases even shrinks, where airwaves are reallocated from radio and TV to mobile data. Of course, the relevance of broadcasters does not depend mainly on the resolution they’re transmitting their content in, but this widening gap does add to the worries many of them have about staying relevant in a time where we are witnessing a shift from linear TV watching to on-demand viewing, happening right under our eyes.

WHERE BROADCAST TV IS NOW:
It’s 2020, and America’s biggest sporting event, the Super Bowl, only just now got broadcast in 4K for the first time, on selected distribution channels and, significantly, streaming platforms. It may be telling that while the production mostly was shot with HDR cameras, the base resolution was 1080p (with some 720p thrown in for good measure), and upscaled to 4K for distribution. The 2018 World Championship soccer games were shot and offered in 4K/HDR by broadcasters in some 25 countries on one-off pop-up channels, removed again as soon as the event was over. 2019 had no such major sports event, and this year we’ll have the European Championships, likely following the same patterns as the world cup two years earlier. The other main sports event this year is going to be the Olympic Games and again the prospects for 4K TV owners aren’t great, since the transmission rights in most countries are held by public broadcasters, who have even more difficulty ponying up the money needed to facilitate UHD programs than commercial ones. In another ironic twist, the 2020 Olympics take place in Tokyo, Japan – the country that’s the farthest advanced with 8K production. The 8K feed is expected to be available only domestically, but in Japan the market penetration of 8K TVs is going to be lower yet than in North America and even Europe. That’s because Japanese living rooms are typically much smaller than American ones, and TV sizes are proportionally smaller (and resolutions accordingly lower).

WILL BROADCAST TV EVER CATCH UP:
Will broadcasters ever catch up with the resolutions consumer TVs have arrived at, or should we accept that there will forever be a discrepancy between the capabilities of the displays we’re watching and the content we’re viewing on it? Given the economic realities of the TV business, probably the latter. This is not a new phenomenon however. Even as HDTV hardware had attained dominance over SDTV in the market, most channels were still in HD. It’s just that the gap is getting wider. Someone watching the local news on a high-end TV in 2020 may very well be looking at an SD signal upscaled for an 8K display. That will not look great. Whether it’s acceptable depends on how critical the consumer is, and on how compelling the content.

THE HDR ALTERNATIVE:
One way for broadcasters to catch up with the TV hardware evolution is to start transmitting programs in HDR. According to the Ultra HD Forum, 1080p HD with HDR also qualifies as Ultra HD and frankly, improved dynamic range contributes more to picture quality than increased spatial resolution. It takes only a modest amount of extra bandwidth – between 0% and about 25% over an SDR channel, depending on the HDR format used. This changes the economics drastically. To what extent broadcasters will need to overhaul their production workflow again depends a lot on what HDR format they choose. More about that in a future article. We seem to have reached an inflection point. What it means for TV hardware and broadcast business only time will tell.
