AV-over-IP: It’s Here. Time To Get On Board!

At InfoComm next week in Las Vegas, I look forward to seeing many familiar faces – both individuals and manufacturers – that have frequented the show since I first attended over 20 years ago. And I also expect to find quite a few newcomers, based on the press releases and product announcements I’ve been receiving daily.
Many of those newcomers will be hawking the latest technology – AV-over-IP. More specifically, transporting video, audio, and metadata that are encoded into some sort of compressed or lightly-compressed format, wrapped with IP headers, and transported over IP networks.
This isn’t exactly a new trend: The broadcast, telecom, and cable/satellite worlds have already begun or completed the migration to IT infrastructures. The increasing use of optical fiber and lower-cost, fast network switches are making it all possible. Think 10 gigabit Ethernet with single-mode fiber interconnections, and you can see where the state-of-the-art is today.
You’ve already experienced this AV-over-IP phenomenon if you watch streaming HD and 4K video. Home Internet connection speeds have accelerated by several orders of magnitude ever since the first “slow as a snail” dial-up connections got us into AOL two decades ago. Now, it’s not unusual to have sustained 10, 15, 25, and even 50 megabit per second (Mb/s) to the home – fast enough to stream Ultra HD content with multichannel sound.
And so it goes with commercial video and audio transport. Broadcast television stations had to migrate to HD-SDI starting nearly 20 years ago when the first HDTV broadcasts commenced. (Wow, has it really been that long?) Now, they’re moving to IP and copper/fiber backbones to achieve greater bandwidth and to take advantage of things like cloud storage and archiving.
So why hasn’t the AV industry gotten with the program? Because we still have a tendency to cling to old, familiar, and often outdated or cumbersome technology, rationalizing that “it’s still good enough, and it works.” (You know who you are…still using VGA and composite video switching and distribution products…)
I’ve observed that there is often considerable and continual aversion in our industry to anything having to do with IT networks and optical fiber. And it just doesn’t make any sense. Maybe it originates from a fear of losing control to IT specialists and administrators. Or, it could just be a reluctance to learn something new.
The result is that we’ve created a monster when it comes to digital signal management. Things were complicated enough when the AV industry was dragged away from analog to digital and hung its hats on the HDMI consumer video interface for switching and distribution. Now, that industry has created behemoth switch matrices to handle the current and next flavors of HDMI (a format that never was suitable for commercial AV applications).
We’ve even figured out a way to digitize the HDMI TMDS signal and extend it using category wire, up to a whopping 300 feet. And somehow, we think that’s impressive? Single-mode fiber can carry an HD video signal over 10 miles. Now, THAT’S impressive – and it’s not exactly new science.
So, now we’re installing ever-larger racks of complex HDMI switching and distribution gear that is expensive and also bandwidth-capped – not nearly fast enough for the next generation of UHD+ displays with full RGB (4:4:4) color, high dynamic range, and high frame rates. How does that make any sense?
What’s worse, the marketing folks have gotten out in front, muddying the waters with all kinds of nonsensical claims about “4K compatibility,” “4K readiness,” and even “4K certified.” What does that even mean? Just because your switch or DA product can support a very basic level of Ultra HD video with slow frame rates and reduced color resolution, it’s considered “ready” or “certified?” Give me a break.
Digitizing HDMI and extending it 300 feet isn’t future-proof. Neither is limiting Ultra HD bandwidth to 30 Hz 8-bit RGB color, or 60 Hz 8-bit 4:2:0 color. Not even close. Not when you can already buy a 27-inch 5K (yes, 5K!) monitor with 5120×2880 resolution and the ability to show 60 Hz 10-bit color. And when 8K monitors are coming to market.
So why we keep playing tricks with specifications, and working with Band-Aid solutions? We shouldn’t. We don’t need to. And the answer is already at hand.
It’s time to move away from the concept of big, bulky, expensive, and basically obsolete switching and distribution hardware that’s based on a proprietary consumer display interface standard. It’s time to move to a software-based switching and distribution concept that uses an IT structure, standard codecs like JPEG2000, M-JPEG, H.264, and H.265, and everyday off-the-shelf switches to move signals around.
Now, we can design a fast, reliable AV network that allows us to manage available bandwidth and add connections as needed. Our video can be lightly compressed with low latency, or more highly compressed for efficiency. The only display interfaces we’ll need will be at the end points where the display is connected.
Even better, our network also provides access to monitoring and controlling every piece of equipment we’ve connected. We can design and configure device controls and interfaces using cloud-based driver databases. We can access content from remote servers (the cloud, again) and send it anywhere we want. And we can log in from anywhere in the world to keep tabs on how it’s all functioning.
And if we’re smart and not afraid to learn something new, we’ll wire all of it up with optical fiber, instead of bulky cables or transmitters and receivers to convert the signals to a packet format and back. (Guess what? AV-over-IP is already digital! You can toss out those distance-limited HDMI extenders, folks!)
For those who apparently haven’t gotten the memo, 40 Gb/s network switches have been available for a few years, with 100 Gb/s models now coming to market. So much for speed limit issues…
To the naysayers who claim AV-over-IP won’t work as well as display interface switching: That’s a bunch of hooey. How are Comcast, Time Warner, NBC, Disney, Universal, Netflix, Amazon, CBS, and other content originators and distributors moving their content around? You guessed it.
AV-over-IP is what you should be looking for as you walk the aisles of the Las Vegas Convention Center, not new, bigger, and bulkier HDMI/DVI matrices. AV-over-IP is the future of our industry, whether we embrace it or are dragged into it, kicking and screaming.
Are you on board, or what?
CES 2016 In The Rear View Mirror

I’m a little less than a week back from one of the world’s largest trade shows, the 2016 International CES. According to press releases from the Consumer Technology Association (CTA), the new name for the Consumer Electronics Association, upwards of 170,000 people attended the show this year, which was spread out over several venues in Las Vegas.
Based on the crowds I saw, I’d say that number wasn’t far off. Walking through booths in the Las Vegas Convention Center gave me the feeling of strolling along the beach, unaware that a tidal wave was sneaking up on you – one minute you had a particular exhibit all to yourself, and the next, you were swamped by a sea of bodies adorned with CES badges.
Trying to predict which trends in electronics will be “hot” each year is basically a fool’s errand. Going into the show, I was deluged with press releases about “Internet of Things” gadgets, and the show didn’t disappoint – I saw everything from connected thermostats and body sensors to pet food dispensers and shower heads that monitor how much water each member of your family uses – and record that data, too.
Last year, the show was all about Ultra HDTV, with some unusual video aspect ratios and pixel counts thrown in. This year, I figured high dynamic range (HDR) would be the “hot” item in every booth. Surprisingly, it wasn’t generating all that much buzz, even though it was featured in the Sony, Samsung, LG, and Chinese TV booths. Instead, there seemed to me much more interest in virtual reality (VR); examples of which were to be found everywhere in the LVCC and also over at the Sands Expo Center.
What was an eye-opener (although not entirely unexpected) was the reduction in booth space devoted to televisions in the Samsung, Panasonic, and LG booths. Sony chose to use Ultra HDTVs to illustrate HDR, wide color gamut, and local area dimming concepts, while Panasonic largely ignored TVs altogether, featuring just a 65-inch UHD OLED TV in one part of their booth and a 55-inch 8K LCD set in another; primarily to demonstrate 8K signal transport over optical fiber.
LG and Samsung devoted more real estate than ever before to connected and “smart” appliances, tablets, smartphones, and personal electronics like smart watches, subtly pushing TVs (of which there were still plenty, believe me) to a secondary role with less square footage. The fact is; appliances are more profitable than TVs these days…WAY more profitable. And Samsung and LG had plenty of refrigerators, ovens, washers, and even dryers out for inspection.
For LG, CES was a big “coming out” party for their expanding line of OLED Ultra HDTVs – they were everywhere, dazzling with their deep blacks and saturated colors. But LCD still plays a part in the LG ecosystem: The 98-inch 8K LCD panel that blew us away last year made a return appearance, as did the 105-inch 21:9 5K (5120×2160) model.
Over in the Samsung booth, they kept the “mine’s bigger than yours” contest going with a 170-inch Ultra HDTV based on a LCD panel fabbed at CSOT in China and equipped with quantum dots. (Last year, Samsung insisted their quantum dot illumination technology was to be called “nanocrystals.” This year, they did a 180-degree turn, and are now calling them quantum dots.) A curved 8K TV and some demos of live broadcast Ultra HD with HDR were also showcased alongside the company’s new Ultra HD Blu-ray player ($399 when it ships in the spring).
The “towers” and stacks of LG and Samsung televisions we used to marvel at a decade ago have now found their way into the ever-expanding booths of Chinese TV brands like Hisense, TCL, Changhong, Haier, Konka, and Skyworth. (Not familiar names? Don’t worry, you’ll get to know them soon enough.) And notable by its absence was Sharp Electronics, whose US TV business and assembly plant in Mexico were acquired by Hisense last year. That’s quite a change from ten years ago, when the company held a 21% worldwide market share in LCD TV shipments.
To be sure, there was a Sharp meeting room w-a-y in the back of the Hisense booth, which was enormous – almost as big as TCL’s behemoth in the middle of the Central Hall. And the Konka, Changhong, and Skyworth booths weren’t far behind in size. If you needed to see the writing on the wall regarding the future of television manufacturing, it couldn’t have been more clear – everything is slowly and inexorably moving to China. (It’s a good bet that the LCD panel in your current TV came out of a Chinese or Taiwanese assembly plant!)
TVs were just part of the story in Las Vegas. I had been waiting a few years to see which companies would finally pick up the baton and start manufacturing 802.11ad Wi-Fi chipsets. For those readers who haven’t heard of it before, 802.11ad – or its more common names, “Wireless Gigabit” and “Certified Wireless Gigabit” is a standard that uses the 60 GHz millimeter-wave band to transmit high-speed data over 2 GHz-wide channels.
Considering that the current channels in the 2.4 GHz and 5 GHz band are only 20 MHz wide, and that the 802.11ac channel bonding protocol can only combine enough of them to create a 160 MHz channel, that’s quite a leap in bandwidth! The catch? 60 GHz signals are reflected by just about solid object, limiting their use to inside rooms. But with high-power operation and steerable antennas, those signals can travel a pretty good distance.
In-room, high-bandwidth operation is perfect for streaming video – even at 4K resolution – from phones, tablets, set-top boxes, and even Blu-ray players to TVs, projectors, AV receivers, and switching and distribution gear. Qualcomm had demos of numerous ready-to-manufacture tri-band modems (2.4/5/60 GHz), along with LETV’s latest smart phone with a built-in 60 GHz radio chip. And SiBEAM, a part of Lattice Semiconductor, showed 4K streaming through their WiHD technology, along with close-proximity interface coupling using SNAP to download images and video from a waterproofed GoPro camera.
Lattice had some other tricks up their sleeve in their meeting room. One of those was using a Windows 10 phone with a MHL (Mobile High-definition Link) connection through USB Type-C to create a virtual desktop PC. All that needed to be added was a mouse, a keyboard, and monitor. In another area, they showed a scheme to compress Ultra HD signals before transmitting them over an HDBaseT link, with decompression at the far end. This, presumably to overcome the 18 Gb/s speed limit of HDMI 2.0.
Not far away, the “funny car” guys at the MHL Consortium showed their superMHL interface linking video to another LG 98-inch 8K LCD display. Converting what was once a tiny, 5-pin interface designed for 1080p/60 streaming off phones and tablets to a 32-pin, full-size symmetrical connector that can hit speeds of 36 Gb/s seems like putting Caterpillar truck tires and a big-block Chevy engine in a Smart Car to me…but they did it anyway, and added support for USB Type-C Alternate mode. Now, they’re ready for 8K, or so they keep telling me. (That’s fine, but the immediate need is for faster interfaces to accommodate Ultra HD with 10-bit and 12-bit RGB color at high frame rates. Let’s hear about some design wins!)
At the nearby VESA/DisplayPort booth, there were numerous demonstrations of video streaming over USB Type-C connections in Alternate mode, with one lash-up supporting two 1920x1080p monitors AND a 2550×1536 monitor, all at the same time. DP got somewhat faster with version 1.3 (32 Gb/s) and now a new version (1.4) will be announced by the end of January. The VESA guys also had a nice exhibit of Display Stream Compression (DSC), which can pack down a display signal by a 2:1 or 3:1 ratio with essentially no loss or latency (a few microseconds). If we’re going to keep pushing clock speeds higher and higher, compression is inevitable.
The world of display interfacing appears to becoming more disjointed, what with the majority of consumer devices still supporting HDMI 1.4 and 2.0, while an increasing number of computer and video card manufacturers are jumping on the DisplayPort bandwagon (Apple, HP, and Lenovo, among others). How superMHL will fit into this is anyone’s guess: The format is TMDS-based, like HDMI, but outstrips it in every way (HDMI 2.0 does not support DSC or USB Type-C operation). Do we really need two TMDS-based interfaces, going forward?
Speaking of USB Type-C, everybody and their brother/sister at CES had Type-C hubs, adapters, and even extenders out for inspection. If any connector is going to force the competing display interface standards to get in line, it will be this one. Apple, Intel, Lenovo, and several phone/tablet manufacturers are already casting their lots with Type-C, and it looks to be the next “sure thing” as we head toward a universal data/video/audio/power interface. I even came home with a credit card-sized press kit with a reversible USB 2.0 / 3.0 Type-C plug built-in!
So – how about HDR? Yes, a few companies showed it, and there were spirited discussions over dinner whether OLEDs could actually show signals with high dynamic range (they most assuredly can, as they can reproduce 15 stops of light from just above black to full white without clipping) and whether you actually need thousands of cd/m2 to qualify as an HDR display (I’m not in that camp; displays that bright can be painful to look at).
For LCDs, quantum dots (QDs) will lead the way to HDR. Both QD Vision and 3M had demos of quantum dot illuminants, with QD Vision focusing on light pipes for now and 3M partnering with Nanosys to manufacture a quantum dot enhancement film. Both work very well and provide a much larger color gamut than our current ITU Rec.709 color space, which looks positively washed-out compared to the more expansive Rec.2020 color gamut associated with UHD and HDR. QD Vision also showed the reduction in power consumption over OLEDs when using QDs. However, you won’t get the deep blacks and wide viewing angles out of an LCD in any case, so a few more watts may not matter to the videophiles.
The Ultra HD Blu-ray format had its formal debut at CES with Panasonic and Samsung both showing players. The latter can be pre-ordered for $399 and will ship in the spring. (Remember when Samsung’s first-ever Blu-ray player sold for nearly $2,000 almost a decade ago?) To support HDR – which requires 10-bit encoding – the HDMI interface must be type 2.0a to correctly read the metadata. That can be in the DolbyVision format, or the Technicolor format, but the baseline definition is HDR-10.
I saved the best for last. Every year, LG Display invites a few journalists up to what we call the “candy store” to see the latest in display technology. And this year didn’t disappoint: How about dual-side 55-inch flexible OLED TVs just millimeters thick? Or a 25-inch waterfall (curved) display that could form the entire center console in a car, with flexible OLEDs in the dashboard creating bright, colorful, and contrasty gauges?
LGD has WAY too much fun coming up with demos for this suite. I saw four 65-inch OLED panels stacked on end, edge to edge, and bent into an S-curve to create a 2.2:1 ratio widescreen UHD+ display. And it also had video playing on both sides. In another location, I saw a jaw-dropping 31.5” 8K LCD monitor with almost perfect uniformity, and an 82-inch “pillar” LCD display.
How about a 55-inch UHD OLED display rolled into a half-pipe, with you standing at the center, playing a video game? Talk about filling your field of view! Next to it was a convex 55-inch display, wrapped around a ceiling support pole. And next to that, a 55-inch transparent OLED display with graphics and text floating over real jewelry, arranged on tiers. The actual transparency index is about 40% and the concept worked great.
The icing on the cake was an 18-inch flexible OLED with 800×1200 resolution that could be rolled up into a tube or a cone-like shape while showing HD video. This was one of those “I gotta get me one of these!” moments, but significantly, it shows how OLED technology has matured to the point where it can be manufactured on flexible substrates. And what is the largest market in the world or displays? Transportation, where G-forces and vibration eventually crack rigid substrates, like LCD glass.
That’s just a snapshot of what I saw, and I haven’t even mentioned drones (buzzing all over the place), fold-up scooters and hoverboards, smart appliances, pet cams, alarms that alert you when an alarm goes off (really!), wooden smartphones (really!), talking spoons and forks (really!), toothbrushes linked to video games (would I kid you?), and 4K action cams with built-in solar cell chargers.
Gotta run now. My phone just sent me a Wi-Fi alarm that a Bluetooth-connected doorbell camera spotted the UPS guy delivering a package I was already alerted about via email to my desktop that signaled a buzzer via ZigBee in my virtual desktop PC that was connected wirelessly to my smartphone, currently streaming 4K video over a 60 GHz link to my “smart” TV that is also…also…also…
Oh, great. Now I’ve forgotten what I was talking about…Does anyone make an iRemember app? (Look for my “second thoughts” column later this month…)
HDMI 2.0 Is Here…And It’s Not Fast Enough?

This morning, the HDMI Forum announced the release of HDMI 2.0, which was almost two years in the making. The impetus for this new standard was and continues to be 4K, which requires such increases in data rates that the older 1.4 version can’t support it, except at slow frame rates.
Now, HDMI 2.0 has a maximum data rate of 18 gigabits per second (Gb/s), slightly faster than DisplayPort’s 17.2 Gb/s. If you do the math, this should be fast enough to transport 3840×2160 video with frame rates of 50 and 60 Hz, using 8-bit and 10-bit color (at 60 Hz, the clock rate for 8-bit 4K is about 14.9 Gb/s; with 10-bit color, about 17.9 Gb/s).
Here are the highlights from the official press release:
“HDMI 2.0, which is backwards compatible with earlier versions of the HDMI specifications, significantly increases bandwidth up to 18Gb/s and adds key enhancements to support continuing market requirements for enhancing the consumer video and audio experience. New functionality includes:
– Support for 4k@50/60, (2160p: 4 times the clarity of 1080p/60 video resolution)
– Up to 32 audio channels for a multi-dimensional immersive audio experience
– Up to 1536kHz audio sample frequency for the highest audio fidelity
– Simultaneous delivery of dual video streams to multiple users on the same screen
– Simultaneous delivery of multi-stream audio to multiple users (up to 4)
– Support for the wide-angle theatrical 21:9 video aspect ratio
– Dynamic synchronization of video and audio streams
– CEC extensions provides expanded command and control of consumer electronics devices through a single control point
HDMI 2.0 does not define new cables or new connectors. Current High Speed cables (Category 2 cables) are capable of carrying the increased bandwidth.”
After reviewing the specifications, it appears to me that the HDMI Forum was trying to squeeze every last drop of speed out of the existing connector/interface architecture without having to re-engineer the standard. There’s no mention of locking connectors (a bugaboo of the broadcast and AV industries). Nor is there any discussion of speeding up HDCP key exchanges beyond what’s already been accomplished with InstaPort. But an HDMI 2.0 standard should eliminate the need for two or even four separate HDMI ports to playback 4K content (several TV and projector manufacturers currently use this approach).
Adding multiple channels of audio and increasing the sampling frequency is relatively simple stuff, as the bit rates for audio are a small fraction of those needed for 2K and 4K video. And you can already deliver two separate video streams through one HDMI connector – it’s only a bandwidth issue; the new standard just establishes a protocol for doing so. Supporting 21:9 isn’t all that big a deal, either.
I’m not sure what “dynamic synchronization of video and audio streams” means yet and will have to talk to the folks at HDMI Licensing to get a better explanation. As for CEC, it appears that control functionality has been souped-up beyond the basic command sets used to operate AV receivers and Blu-ray players.
What’s clear now is that HDMI 2.0 is NOT going to be the big breakthrough many of us analysts and writers expected, and that it will NOT be able to transport 10-bit and 12-bit 4K video running at higher frame rates (>60 Hz). Both of these specifications are necessary to develop high dynamic range (HDR) video and movie content.
Nor is there any indication of supporting a high-speed data bus overlay like Thunderbolt, which is becoming more important with the growth in popularity of tablets and smart phones, not to mention ultrabooks. These devices are leading the industry changeover to single, dense, multifunction interfaces across all sorts of CE products.
In contrast; over at VESA, they’ve already commenced development of Display Stream, a new interface that will use “light” JPEG compression to push data rates up to 25 Gb/s and beyond over conventional DisplayPort connections. This is a more “future-proof” approach to display connectivity and reflects the current state of 4K and UHDTV product and content development, what with all of the 4K television announcements that have been made this year.
But the reality is that HDMI dominates the CE marketplace and is making major inroads to commercial AV and broadcast installations. The market has largely ignored DisplayPort, despite the facts that (a) there are currently no royalties associated with its use, (b) its connectors come in many different flavors, including support for mobile and fiber optic interfaces, and (c) it already supports a high-speed data bus overlay – the 20 Gb/s Thunderbolt layer.
Maybe they’ll get it right next time..
CES 2012: ANOTHER OPENING, ANOTHER SHOW

There’s still a debate about whether the U.S. economy has turned the corner and is on the rebound. As far as CES 2012 attendees were concerned, that ‘corner’ is way back in the rear-view mirror! According to official CES reports, over 140,000 people flocked to the Las Vegas Convention Center for the world’s second-largest annual gadget orgy (and at least 100,000 of them were constantly waiting on the South Hall cab lines).
The show was notable for several things. First, the expanding presence of Chinese CE brands, like TCL, Changhong, Haier, and Hisense. (Never heard of them? You’re not alone.) Second, this show was Microsoft’s curtain call, as they’ve decided to go the route of Apple and stage their own product intros in the future.
Third, there was a decided pull-back on 3D (aside from LG, who made it the focus of their booth) and a renewed emphasis on ‘connected’ TVs in all shapes and flavors. And fourth, gesture recognition made a well-deserved comeback this year after being mostly an afterthought in 2011.
Overall, the show had less of a “let’s build it because we can” feel, and more of a “let’s actually make a practical gadget that people will want to buy” buzz. Still, there were the usual surprises – some were telegraphed in advance, while others showed up quite unexpectedly.
Here’s an example. Both LG and Samsung showed 55-inch organic light-emitting diode (OLED) TVs at the show. LG’s unveiling had been common knowledge, while Samsung’s was only revealed to members of the press under embargo. But both showings attracted constant crowds, as OLEDs in this size are a rare sighting!
LG’s 55-incher is supposedly a production model and will come from a new Gen 8 fab in Korea. It uses Kodak’s white OLED technology (purchased by LG a couple of years ago), with discrete red, green, blue, and white filters applied. Samsung’s approach is a bit trickier and employs discrete red, green, and blue OLEDs. Both panels looked terrific, and thank goodness for LG Display’s separate, quieter and far less chaotic suite at the Bellagio, where I could examine the OLED TV more closely.
It’s hard to upstage a demo like that, but Sony almost pulled it off by showing 46-inch and 55-inch inorganic LED TVs. What’s an inorganic LED? It’s the same technology that powers those outdoor LED signs you see alongside highway and inside stadiums and arenas. Only Sony figured out a way to stuff 6.2 million small-pitch RGB LEDs into a TV, using an expensive and time-consuming wire bonding process that ensures (for now) that these products won’t come to market any time soon. But these TVs still looked spectacular and livened up what was otherwise a rather sedate Sony booth, compared to 2011 (remember that 92-foot passive 3D screen and the astronaut DJ?)
Just down the hall, Sharp left no doubts about its product marketing strategy for the next few years by showcasing a new 80-inch professional video display with touchscreen overlay. The Aquos Touch is adapted from Sharp’s 80-inch Aquos TV that launched in the fall of 2011, and complements the 70-inch product already in the line. Given that Sharp’s market share in TVs has inexplicably dwindled to the mid-single figures, this is an interesting approach – but the playing field is wide open. And the pro AV channel is very interested in large, self-contained displays that could replace traditional two-piece projector installations.
Sharp also tickled our fancy with several Freestyle “portable” LCD TVs, including models as large as 60 inches. These TVs have been designed to be as light as possible and use a WiFi-based solution to stream HD content, so you can pretty much pick ‘em up and move ‘em wherever there’s an AC outlet. (I guess that includes the garage if you want to watch a football game with your best buds and keep the noise level down…)
3D was around, but clearly took a back seat to other demos. Still, Toshiba showed several examples of 1080p and 4K autostereo 3D TVs in their booth. These demos once again required the viewer to stand in specific locations to receive the full autostereo effect, and Toshiba thoughtfully provided small green circles with arrows in them as visual cues – when both were seen, you were positioned in a ‘sweet spot.’ Toshiba has clearly walked away from active 3D and has a few passive 3D sets in their line, but it appears autostereo is their game plan for the near future. (And yes, the 4K TV looked spectacular.)
Next door, Panasonic anted up big time by showing a new line of LED-backlit LCD TVs that will be available in sizes to 55 inches, immediately casting doubts as to the company’s future plans for plasma TVs. These ET-series sets employ Panasonic’s IPS-Alpha LCD panels and I have to admit, they looked doggone good, particularly at wide viewing angles. Still, the company had plenty of plasma announcements, including faster subfield drive for improved motion rendering and even lower power consumption from the 2011 plasma lineup. For my money, plasma is still the way to go – that is, until OLED prices drop low enough.
LG is head over heels in love with 3D. That’s the only conclusion anyone could make after cruising through their booth, which featured an enormous panoramic Cinema 3D videowall (passive, of course) at the Central Hall entrance. Inside, LG’s 55-inch OLED was shown with 3D and 2D content, and a nearby exhibit showcased an 84-inch 4K 3D LCD monitor. (Sorry, it’s not for sale – yet…) 3D popped up on so many LG products that I expected the ‘smart’ washer and dryers also located in the massive exhibit to be labeled ‘Cinema 3D’ as well. (Technically speaking, you could apply film patterned retarders to the front port of the washer – oh, never mind.)
As mentioned earlier, the overwhelming presence of numerous Chinese brands at the show clearly shows which way the wind’s blowing these days. Haier brought back their clever wireless LCD TV demo from two years ago, and this version builds the inductive coupling system into the pedestal. Yes, it is completely wireless, power and all. (Amazing what you can do with a big transformer!) Elsewhere in the Haier booth, you could find a “brain wave TV” demo that was supposed to allow you to “think” of changing channels and raising/lowering volume. (It kinda worked.)
Changhong and TCL both exhibited some really sharp-looking LCD TV designs, proving that Japan and Korea don’t have any special magic in this area. All of the companies had 3D sets out for inspection with the majority using passive 3D technology, while several of the models were ‘smart’ TVs with built-in WiFi Internet connections for streaming video. No content partnerships were announced or seen, however. It’s telling that the size of these booths is getting larger with each year, while some of the Japanese TV manufacturers are slowly shrinking.
Speaking of ‘smart’ TVs, everybody had them – Sharp, LG, Samsung, Sony, Toshiba, Panasonic, Haier, TCL, Hisense, you name it. That included connected Blu-ray players. Samsung’s Apps for TV seems to be growing by leaps and bounds, and Panasonic’s Viera Connect has also added content partners. LG’s ‘smart’ TV featured a demo of the new Google TV interface, which certainly looked a lot more user-friendly that the last implementation and presented a much more logical process for searching and finding video content on the Web.
Many of the companies exhibiting at CES used Rovi’s Total Guide EPG (or variations of it) to search out and find Web video content, as well as more traditional sources like cable, satellite, and even broadcast TV. Rovi has ported their guide to every possible platform and in their suite at Caesar’s Palace, showed implementations on set-top boxes, tablets, and a variety of TVs. The company is also into ad insertion and content delivery management systems. In short, they find it, stream it, and monetize it.
How about connecting all of this stuff together? Rainbow Fish had a small booth in the rear of the South Hall, but it was worth hunting down. They are selling direct HDMI-to-fiber optic connectivity kits that use multimode fiber and require only a separate USB connection at the TV to supply 5 volt phantom power to the lasers. Everything is built into the plugs, so there’s no need for separate converter boxes.
A few booths away, 3M was hawking a new ‘unbreakable’ HDMI cable design. Its super-flat and you can fold it, bend it, twist it – in short, pretty much abuse it any way you want. But you won’t screw up the signal, as 3M’s presentation showed. There are two types of cables – one for consumer applications, and one for computers (notebooks, I guess) and 3M offers plenty of options for color-coding the cable ends. They won’t be sold directly, but through OEM partners. Marry these with the drop-forged HDMI plugs I saw at a nearby booth, and you’ve got a ‘super’ HDMI connection.
Don’t want to plug anything in? Silicon Image has rejuvenated the Wireless HD standard with its acquisition of SiBeam, and was demonstrating 60 GHz wireless HDMI connectivity from tablets and notebook computers to large TVs. Wireless HD is a close range HDMI connectivity standard that is not WiFi based, and the chipsets and associated connections can now be manufactured in sizes small enough to build into a tablet. So, who will be the first to add it to their tablet? (My vote is for the next-generation iPad.)
Over in the Hilton, the WHDI Consortium had their demos of 5 GHz wireless HDMI interfaces running on professional camcorders, tablets, notebooks (including wireless DisplayPort and wireless VGA, for some unknown reason), and TVs. Asus showed a production notebook computer with WHDI connectivity built-in, and HP is now selling a WHDI connectivity kit for computers and TVs. Atlona won a Best of CES award for its WHDI-based LinkCast wireless HDMI package. Can WHDI compete with Wireless HD? We’ll see as 2012 unfolds.
Have you ever dropped your cell phone in a pool, or in the toilet? HzO had a demonstration of their proprietary waterproofing system for handheld CE devices that showcased an iPhone merrily playing away a selection of iTunes while dunked in a fish tank for several hours. Other phones that had been ‘treated’ also took a dive. Waterproofing was a big thing at CES, as I spotted several tanks full of phones, camcorders, and still cameras.
I mentioned gesture recognition earlier. PrimeSense, the company behind Microsoft’s Kinect Xbox motion recognition system, had an impressive demo of gesture recognition in the South Hall, and has licensed an add-on MS package to Asus called Xtion. A dancer in the booth kept things hopping with a ‘60s psychedelic imaging sequence that triggered all kinds of ‘trippy’ graphics and was fun to watch for a few minutes.
Over in the Samsung booth, crowds lined up for the most impressive MS demo. Samsung’s implementation also incorporates voice and facial recognition, taking and storing a picture of each user with a top-mounted camera. The command “Hi, TV!” activates a menu bar along the bottom of the screen, and the user can then command channel and volume changes on the TV as well as navigate menus and delve into Samsung’s ‘smart’ TV system. Hand gestures are also used to raise and lower volume and navigate up/down through channels.
Variations of gesture recognition were also seen in the LG and Haier booths, as well as by specialty manufacturers. Some systems require the use of a wand to control the TV; others simply rely on broad gestures – Haier’s demo had a fellow actually boxing in sync with the video game, and I was afraid he was going to deck himself at some point!
Other cool products at the show included Sharp’s 8K-resolution LCD TV, Victorinox’ 16 GB USB Swiss Army Knife (I kid you not), Belkin’s four-port ScreenCast wireless HDMI transmitter/receiver, Duracell’s cordless smart phone charging system (yes, it really works), Ford’s cloud-connected EVO concept car with personal health sensor monitoring, LG Display’s Art TV concept design, JVC’s new 4K camcorder for $4,000, BenQ’s new LCD monitors for gamers with instant picture setting changes, and Silicon Images’ demo of 3D mobile high-definition link (MHL) connectivity that resulted in the first TV screen I’ve ever seen with “airplane mode” on it.
I’d be remiss by not commenting on one legendary company’s presence at the show. As many readers know, Kodak has been in a death spiral for the past decade as its core film business fades away and digital imaging takes over. The company recently received a warning from the New York Stock Exchange that it might be delisted (last time I checked, shares were selling at about 61 cents) and it is about to file for Chapter 11 bankruptcy protection in order to auction off its patents in digital imaging.
So what the heck was the Great Yellow Father showing in that enormous booth in the upper South Hall? Why, its line of color inkjet printers, of course! Supposedly, color inkjets will be the salvation of Kodak, or at least that’s what the current management (ex-HP) tells us. Only problem is, Kodak’s market share in inkjet printers for 2011 was less than 5%, and they’re fast running out of cash for day-to-day operations.
Somehow, Kodak’s long-time competitor Fuji managed to support both film-based and digital imaging and not drive over a cliff. At CES, they showed a new 16-megapixel digital camera system with interchangeable lenses, upgraded their line of point-and-shoots, expanded the FinePix digital camera offerings, and continue to market a clever 3D digital camera. (Maybe Kodak ought to hire some of the Fuji guys…)
I’ll have more coverage of CES 2012 during my annual Super Tuesday Technology Trends presentation at InfoComm 2012 this coming June in Las Vegas. See you there!
