InfoComm 2018 In The Rear View Mirror

If you managed to make it out to this year’s running of InfoComm, you might have summarized your trip to colleagues with these talking points:

(a) LED displays, and

(b) AV-over-IT.

Indeed; it was impossible to escape these two trends. LED walls and cubes were everywhere in the Las Vegas Convention Center, in many cases promoted by a phalanx of Chinese brands you’ve likely never heard of. But make no mistake about it – LEDs are the future of displays, whether they are used for massive outdoor signage or compact indoor arrays.

With the development of micro LED technology, we’re going to see an expansion of LEDs into televisions, monitors, and even that smart watch on your wrist. (Yes, Apple is working on micro LEDs for personal electronics.)

Projector manufacturers are understandably nervous about the inroads LEDs are making into large venues. Indeed; this author recently saw Paul Simon’s “farewell tour” performance at the Wells Fargo Center in Philadelphia, and the backdrop was an enormous widescreen LED wall that provided crystal-clear image magnification (very handy when concertgoers around you are up and dancing, blocking your view of the stage).

 

As for the other talking point – well, it was impossible to avoid in conversations at InfoComm. Between manufacturers hawking their “ideal” solutions for compressing and streaming audio and video and all of the seminars in classrooms and booths, you’d think that AV-over-IT is a done deal.

The truth is a little different. Not all installations are looking to route signals through a 10 Gb/s Cisco switch. In fact, a brand-spanking-new studio built for ESPN in lower Manhattan, overlooking the East River and the Brooklyn Bridge, relies on almost 500 circuits of 3G SDI video through an enormous router. Any network-centric signal distribution within this space is mostly for IT traffic.

That’s not to say that installers are poo-pooing AV-over-IT and the new SMPTE 2110 standards for network distribution of deterministic video. It’s still early in the game and sometimes tried-and-tested signal distribution methods like SDI are perfectly acceptable, especially in the case of this particular facility with its 1080p/60 backbone.

Even so, the writing on the all couldn’t be more distinct with respect to LEDs and network distribution of AV. But there were other concerns at the show that didn’t receive nearly as much media attention.

At the IMCCA Emerging Trends session on Tuesday, several presentations focused on interfacing humans and technology. With “OK Google” and Alexa all the rage, discussions focused on how fast these consumer interfaces would migrate to AV control systems. An important point was made about the need for two-factor authentication – simple voice control might not be adequately secure for say, a boardroom in a large financial institution.

What would the second factor be? Facial recognition? (This was a popular suggestion.) Fingerprints? Retinal scans? A numeric code that could be spoken or entered on a keypad? The name of your favorite pet? Given that hackers in England recently gained access to a casino’s customer database via an Internet-connected thermometer in a fish tank, two-factor authentication for AV control systems doesn’t seem like a bad idea.

Another topic of discussion was 8K video. With a majority of display manufacturers showing 4K LCD (and in some cases OLED) monitors in Vegas, the logical question was: Could resolutions be pushed higher? Of course, the answer is a resounding “yes!”

Display analysts predict there will be over 5 million 8K televisions shipped by 2022 and we’re bound to see commercial monitors adapted from those products. But 8K doesn’t have to be achieved in a single, stand-alone display: With the advent of smaller 4K monitors (some as small as 43 inches), it is a simple matter to tile a 2×2 array to achieve 7680×4320 pixels. And there doesn’t appear to be a shortage of customers for such a display, especially in the command and control and process control verticals.

The other conversations of interest revolved around the need for faster wireless. We now have 802.1ac channel bonding, with 802.11ax on the horizon. For in-room super-speed WiFi, 802.11ad provides six channels at 60 GHz, each 2 GHz wide or 100x the bandwidth of individual channels at 2.4 and 5 GHz.

But wise voices counsel to pay attention to 5G mobile networks, which promise download speeds of 1 Gb/s. While not appropriate for in-room AV connectivity, 5G delivery of streaming video assets to classrooms and meetings is inevitable. Some purveyors of wireless connectivity services like AT&T and Verizon insist that 5G could eventually make WiFi obsolete. (That’s a bit of a stretch, but this author understands the motivation for making such a claim.)

The point of this missive? Simply that our industry is headed for some mind-boggling changes in the next decade. Networked AV, LEDs, 8K video and displays, multi-factor authentication for control systems, and super-fast wireless connections are all in the wings.

And if you were observant at InfoComm, you know it’s coming…and quickly.

Heads Up! Here Comes 8K TV (or, The Case Of The Amazing Vanishing Pixels)

Yes, you read that right: 8K displays are coming. For that matter, 8K broadcasting has already been underway in Japan since 2012, and several companies are developing 8K video cameras to be shown at next month’s NAB show in Las Vegas.

“Hold on a minute!” you’re probably thinking. “I don’t even own a 4K TV yet. And now they’re already on the endangered species list?”

Well, not exactly. But two recent press releases show just how crazy the world of display technology has become.

The first release came from Insight Media in February and stated that, “The 2020 Tokyo Olympics will be a major driver in the development of 8K infrastructure with Japanese broadcaster NHK leading efforts to produce and broadcast Olympic programming to homes…cameras from Hitachi, Astrodesign, Ikegami, Sharp and Sony address the many challenges in capturing 8K video…the display industry plans for massive expansion of Gen 10.5 capacity, which will enable efficient production of 65″ and 75″ display panels for both LCD and OLED TV…. sales of 8K Flat Panel TVs are expected to increase from 0.1 million in 2018 to 5.8 million in 2022, with China leading the way representing more than 60% of the total market during this period.”

Read it again. Almost 6 million 8K LCD and OLED TVs are expected to be sold four years from now, and over 3 million of those sales will be in China.

But there’s more. Analyst firm IHS Markit issued their own forecasts for 8K TV earlier this month, predicting that, While ultra-high definition (UHD) panels are estimated to account for more than 98 percent of the 60-inch and larger display market in 2017, most TV panel suppliers are planning to mass produce 8K displays in 2018. The 7680 x 4320-pixel resolution display is expected to make up about 1 percent of the 60-inch and larger display market this year and 9 percent in 2020.”

According to HIS Markit, companies with skin in the 8K game include Innolux, which will supply 65-inch LCD panels to Sharp for use in consumer televisions and in commercial AV displays. Meanwhile, Sharp – which had previously shown an 85-inch 8K TV prototype – will ramp up production of a new 70-inch 8K LCD display (LV-70X500E) in their Sakai Gen 10 LCD plant. This display was shown in Sharp’s booth at ISE, along with their new 8K video camera.

Sharp showed this 8K camera (BC-B60A) at ISE…

Sony and Samsung are also expected to launch 8K LCD TVs this year. Both companies showed prototypes at CES with Samsung’s offering measuring about 85 inches. Sony’s prototype also measured 85 inches but included micro light-emitting diodes (LEDs) in the backlight to achieve what Sony described as “full high dynamic range,” achieving peak (specular) brightness of 10,000 nits. (That’ll give you a pretty good sunburn!)

Oher players in 8K include LG Display, who already announced an 88-inch 8K OLED TV prior to CES, and Chinese fabricators BOE, AUO, and China Electronics Corporation (CEC). What’s even more interesting is that some of these 8K LCD and OLED panels will be equipped with indium gallium zinc oxide (IGZO) switching transistors.

No, IGZO isn’t a cure for aging. But what it does is provide much higher pixel density in a given screen size with lower power consumption. More importantly, it will allow these 8K TVs to refresh their pictures as fast as 120 Hz – double the normal refresh rate we use today. And that will be important as High Frame Rate (HFR) video production ramps up.

LG Display’s 88-inch 8K OLED display was a real eye-catcher at CES 2018.

Predictably, prices for TVs and monitors using panels with 4K resolution are collapsing. In the AV channel, 4K (Ultra HD) displays are only beginning to show up in product lines, but manufacturers are well aware of pricing trends with Ultra HD vs. Full HD (1920x1080p). With some consumer models now selling for as little as $8 per diagonal inch, the move from Full HD to 4K / Ultra HD will pick up lots of steam.

And with 8K displays now becoming a ‘premium’ product, 4K / Ultra HD will be the ‘everyday’ or mainstream display offering in screen sizes as small as 40 inches and as large as – well, you name it. We’ve already seen 84-inch, 88-inch, and 98-inch commercial displays, and prototypes as large as 120 inches – yes, 10’ of diagonal screen, wrap your head around that – have been exhibited at CES and other shows.

We saw quite a few demonstrations of 4K commercial displays at ISE and expect to see a whole lot more at InfoComm in June, along with the inevitable price wars. And there will be the usual “my encoder handles 4K better than yours with less latency” battles, shoot-outs, and arguments. But that could ultimately turn out to be the appetizer in this full-course meal.

For companies manufacturing signal distribution and switching equipment, 4K / Ultra HD already presents us with a full plate. 8K would be too much to bite off at present! Consider that an 8K/60 video signal using 12-bit RGB color requires a data rate approaching 100 gigabits per second (Gb/s), as compared to a 12-bit, 60 Hz Full HD signal’s rate of about 6 Gb/s, and you can see we will have some pretty steep hills to climb to manage 8K.

Distributing 8K over a network will be equally challenging and will require switching speeds somewhere north of 40 Gb/s even for a basic form of 8K video, which (we assume) will also incorporate high dynamic range and wide color gamuts. 40 Gb/s switches do exist but are pricey and would require 8K signals to be compressed by at least 25% to be manageable. And they’d certainly use optical fiber for all their connections.

To be sure, 4K / Ultra HD isn’t on the endangered species just yet. (For that matter, you can still buy Full HD monitors and TVs, if that’s any comfort.) But whether it makes sense or not – or whether we’re ready or not – it’s “full speed ahead” for 8K displays as we head into the third decade of the 21st century…
