Display Industry – Last week marked my 20th consecutive trip to InfoComm and it was a hectic time in Orlando. I got in Sunday night and spent most of Monday setting up equipment for my four classes and presentations at InfoComm, including two Super Tuesday sessions (Future Trends, Things You Never Thought About) while I was also co-teaching an all-day Super Tuesday session on RF and Wireless Trends.
Wednesday morning brought a 2-hour class on digital video, while my Thursday morning class covered and demonstrated a variety of wireless display and video connectivity systems (none of which used WiFi, by the way). That’s about ten hours’ worth of teaching, and it does take its toll on your voice!
As a result, I didn’t spend a lot of time on the show floor. Even so, I spotted a few trends that are impacting the pro AV industry and will dramatically re-shape it by the end of this decade.
First off, attendance at classes this year was strong, with more than a few sessions selling out. The transition from analog to digital AV is in full swing, and there’s plenty to be learned. More than half the attendees in my classes came from the higher education channel and were either in the process of upgrading to digital signal switching and distribution, or about to embark on that arduous task within the next six months.
There was intense interest in my wireless AV class, which for the first time featured actual products that you can buy now. Clint Hoffman and his crew at Kramer Electronics worked hard to get me a production model of the company’s new KW-11 WHDI transceiver kit, which I promptly installed in my home-made wireless Nook HD+ tablet. This 6 GHz system was used to deliver PowerPoints and 1080p/60 clips from Skyfall as I walked around the 150+ attendees. It worked like a champ!
Peerless AV also provided me with their two-channel WHDI linking system, which we used to transmit 1080p signals to a Sharp 80-inch LCD TV in the corner of the classroom. That same TV was simultaneously receiving low-power ATSC signals on channel 23 from MELD Technologies’ Pico Broadcaster white space system.
On the other side of the room, DVDO’s 60 GHz WiHD Air product was sending clips from Men in Black III from a Panasonic Blu-ray player to the house projection system. And Jim Venable and Alan Ruberg from the Wireless Speaker and Audio Association were demonstrating 5.1-channel wireless surround audio playback of House of Flying Daggers. If anyone in the crowd had doubts about wireless high-bandwidth AV connectivity being real, they were quickly dispelled.
In my Future Trends talk on Tuesday, I identified inexpensive, large LCD displays as growing market disruptors. That was obvious when I walked the show floor, where booths were stuffed with big LCD screens, including some 4K models. Sharp had their big glass on display and also spotlighted their new 32-inch 4K LCD monitors, powered by IGZO backplanes. Samsung, LG, Sony, Panasonic, Planar, NEC, and others made “big LCD” the focal point of their booths.
Not surprisingly, most of the projector manufacturer booths were smaller this year than last. But those that had ‘em to show made sure their lamp-free projectors were located front and center. Lamp-free projection is a big deal now and takes on even more importance with the threat from large LCDs. Panasonic, Optoma, Casio, Sony, projectiondesign, Vivitek, and Mitsubishi all had impressive demos of LED, laser, and hybrid projectors. (Oddly, I walked through the BenQ booth a few times but couldn’t locate their laser DLP models.) Keep an eye on this battle – it’s only going to intensify as more end-users consider the move to “big LCD.”
As for 4K, there were lots of discussions about the pros and cons at the show. It has been pointed out on more than one occasion that we’ve yet to see a single 4K display interface; HDMI or DisplayPort. The trick now is to use several HDMI connections to get data to the screen, but that’s not practical in the long term.
With the pending release of HDMI 2.0 standards and perhaps some more aggressive promotion by VESA of Display Stream (up to 25 Gb/s data rates), I expect all of that to change by next year’s InfoComm. There is considerable demand in the commercial AV space for higher display resolution, both in single screens and tiled displays. Think of process control, command and control, virtual reality, geophysical mapping, and military surveillance as logical candidates.
One of the more intriguing discussions came during Scott Sharer’s closing Super Tuesday session. Fellow panelist Bill Nattress, a principal at Shen Milsom Wilke in Chicago, talked about the pending demise of the conventional conference room and meeting room in favor of ad hoc, no-wall meeting spaces. How will people present there? Projectors aren’t a likely candidate. Perhaps tablets, which will certainly get bigger? Large LCD screens on roll-around stands?
And how will we control AV playback in these spaces? Most likely with advanced gesture control and voice recognition. The two go hand-in-hand, in my opinion, and we are going to see plenty of finished products by 2020; perhaps even sooner. Look for the era of the “touchless” touch screen to start soon.
So, there you have it: 4K, large cheap LCDs, lamp-free projection, wireless high-bandwidth connectivity, faster multifunction interfaces, and gesture/voice control. Keep your eyes on those trends for the rest of the year and I’ll look forward to seeing you in one of my classes next June in Las Vegas! -Pete Putman
