After all the PR hype and anticipation, the 2015 International CES has come and gone, leaving me to edit over 1500 photos and a bunch of videos and sift through stacks of press releases to see what was really significant about the show…and what was just fluff.
Before I drill down to make my top picks, I should point out some trends that have been building for a few years. We all know that the majority of our electronic gadgets (phones, tablets, home alarm systems, televisions, computers, cordless phones, and so on) are manufactured in China and Southeast Asia.
Still, the expanding CES footprint of Chinese brands (Haier, TCL, Hisense, Changhong, Konka, Skyworth) takes some getting used to. So does the shrinking footprint of former Japanese powerhouses like Sony, Sharp, and Toshiba. There is a profound shift in power happening in the CE world as the center of gravity moves farther away from Tokyo and Osaka past Seoul to Shenzen and Shanghai.
Another unmistakable trend is the decline in prices for a wide range of CE products. “Connected health” was a big deal at least year’s show, but is there really any news to be found in $60 Fitbits? Or $149 home security systems? Or $125 32-inch televisions?
Speaking of televisions, they are becoming less important in the overall scheme of things with each passing year. 4K Ultra HD was all the rage last year – this year, everyone had 4K televisions, and many models were equipped with quantum dot backlights for high dynamic range. Of course, there was no shortage of curved televisions in all sizes.
The facts are these: Changhong and TCL can make a large, curved 4K LCD TV with high dynamic range just as easily as Sharp, Samsung, and Panasonic. In some cases, the LCD panels used in these TVs are all coming from the same factory.
Samsung made a big splash this year with their S UHD television line, but they’re using quantum dots just like anyone else. LG showed both quantum dots and their new M+ technology that adds white pixels to an LCD matrix to boost brightness. TCL is selling QD-equipped TVs in China and expects to launch them on these shores this year.
Perhaps surprisingly, LG decided to make a big push for OLED technology, unveiling five new Ultra HD models at the show. While the Chinese also showed OLEDs (as did Panasonic), LG appears to be “all in” with their white OLED technology, claiming manufacturing yields as high as 70%. Well, someone’s got to pick up the torch that plasma dropped in 2013.
For many of these manufacturers, appliances and white goods are taking on a more important role in contributing to the bottom line. The margins are better on high-end refrigerators and washer-dryer sets for the likes of Samsung and LG, even though consumers don’t turn them over as often as televisions. For Panasonic, beauty products are an important income stream.
Cameras and camcorders are still holding their own against mobile phones, surprisingly. I entered the CES arena equipped with both a new Samsung Galaxy 5 phone and a Panasonic Lumix ZS40 camera. While the Galaxy 5 does take some great pictures under ideal conditions, it was no match for the 30:1 optical zoom lens (Leica glass) on the Lumix – the latter allowed me to shoot under, around, and over people to get the photos I needed.
Speaking of mobile phones and tablets, there wasn’t much news to be had at the show. LG showed its updated LG G-Flex 2 and Samsung had a crowd around its Galaxy family of phones and tablets, but there just wasn’t the “BYOD buzz” we’ve seen in previous years. The 5” to 5.5” screen size seems to be a sweet spot for phones now – 6-inch models were scarce in Vegas.
Connecting all of this stuff together made for a more compelling story from my perspective, especially as far as wireless technology goes. I saw more demos of wireless video streaming, wireless appliance control, wireless security systems, and wireless display connectivity at CES than at previous shows.
The 802.11ac channel bonding protocol is becoming increasingly important for making this stuff work in the 5 GHz band. And the wide-open spaces at 60 GHz are starting to attract everyone’s attention – having 2 GHz channels to play with is a lot more appealing for making high bitrate connections than fighting the congestion at 2.4 and 5 GHz.
Display interfaces are getting fast – a lot faster – and relying on compression for the first time. And now we’re starting to see the boundaries blur between small, high-performance mobile display interfaces and full-sized versions, which leads me to wonder why we need so many versions of HDMI and DisplayPort in the first place.
I’d be remiss if I didn’t mention the growing number of automobile manufacturers who set up shop in the North Hall every year. It reminds me of the New York Auto Show, with the likes of Hyundai, VW, Ford, Fiat Chrysler, and Audi showing off their latest high-tech “connected” automobiles that can do everything from mirror your smartphone’s display to recognize speech commands, navigate flawlessly, and even drive themselves.
And there were plenty of alternatives to gasoline-powered engines to seen, from BMW’s i3 electric car to Toshiba’s Mirai hydrogen fuel cell vehicle. All equipped with Bluetooth, 802.11, Sirius, and in some cases, user-customizable dashboard displays using flexible displays (important to survive vibration and G-forces).
Quite a bit to take in over three and a half days! What follows is my list (in no particular order) of significant products and trends I spotted in Vegas. Let’s see if they hold up as the year progresses:
High Dynamic Range – as usual, a hot new technology makes its appearance at the show and quickly becomes a buzzword. HDR Ultra HDTVs were shown by numerous manufacturers at CES; none more prominently as Samsung, who made HDR the centerpiece of their Monday press conference with their S UHD line. Virtually all of these TVs use quantum dot technology to boost image brightness and color saturation, and only one (LG) had an alternative path to HDR with M+ technology.
HDR is a key part of the transition to next-generation television. So are wider color spaces, high frame rates, and increasing resolution. Looks like everyone’s getting into the game, including the Chinese. Interestingly, I saw only one demo of Dolby’s HDR technology in the TCL booth (Vizio also has it), so it appears many homegrown solutions are in the works for HDR displays.
OLEDS Are Back – at least as far as LG is concerned. Seven new Ultra HD OLED TVs were rolled out at CES with sizes ranging from 55 inches to 77 inches, and one of them can flex back and forth from flat to curved surface mode. A partnership with Harman-Kardon should ensure better audio quality than you hear from typical super-thin televisions. (There were even two models featuring bases made from Swarovski crystal!)
With the demise of plasma, videophiles are still looking for displays that can give them the magic combination of deep blacks, saturated colors, and wide viewing angles. Right now, OLEDs are the only game in town, but they’ve proven to be tricky to manufacture with acceptable yields. LG Display seems to have overcome that barrier with these models (which use IGZO TFTs for pixel switching, by the way) and it will be interesting to see the uptake as 2015 winds on.
Super MHL Is Here: The battle for fastest display interface shifts back and forth between Silicon Image and VESA. DisplayPort fired the first salvo with their introduction of version 1.3, raising the maximum data rate to 32 Gb/s and introducing Display Stream compression for the first time. Now, the MHL Consortium has fired back with Super MHL. MHL stands for Mobile High-definition Link, and in its first iteration, allowed transport of 1080p/60 video over the 5-pin micro USB connector found on smartphones and tablets.
But Super MHL is different – it is a full-sized connector with 32 pins and matches the data rate of DP 1.3. The CES demo showed a Samsung 8K display being driven through Super MHL. How would anyone fit this on a mobile device? Does it replace HDMI 2.0? (It’s a LOT faster and uses DS compression, too.) So many questions to be answered…
Talk To Me: Conexant showed a demo of voice control for TV set-top boxes (change channels, bring up program guide, set DVR recordings) that was leap years ahead of their demo from 2013. This system works exceptionally well in noisy environments and can be used to control other devices, such as room lighting, thermostats, and security systems.
Conexant is looking to sell their technology as a system on chip (SoC) to a wide cross section of manufacturers. The trick had been reliable speech recognition in all kinds of high and low noise environments, something that doomed Samsung’s voice control TVs back in 2012. It appears they’ve finally pulled it off, but the focus has shifted away from TVs to set-top boxes this time around.
I’ll Be Watching You: The EyeTribe of Denmark showed an amazing eye tracking and control system at ShowStoppers that can operate tablets and phones and costs all of $99. Yep, you read that right! While Tobii’s impressive demos have focused on laptops and gaming systems, EyeTribe has gone after potentially the biggest market for eye tracking. How many times have you wished you could operate your mobile phone while your hands were full?
Faster Video For All: Giraffic had an intriguing demo of optimizing and speeding up video streaming rates over conventional TCP/IP networks. And it had nothing to do with adaptive bitrate streaming, using H.265 encoding, or AVB protocols. What Giraffic is doing is changing the nature and frequency of HTTP requests. This is the best way I can explain it: Imagine you just sat down with a big piece of chocolate cake and want to eat it as quickly as possible. If you take big bites, you’ll be chewing for a while and some pieces may get stuck in your throat.
But if you start with very small bites (like crumbs) and keep shoveling them in quickly, you’ll finish the cake just as fast – or perhaps faster – than the conventional way of eating. And that’s what Giraffic does – it keeps nibbling at the video stream to ensure continuous delivery, even with 4K content. The company claims they can achieve streaming throughput 200% to 300% faster than conventional video streaming, with no freeze-ups and annoying “buffering” warnings.
4K Blu-ray: Okay, we’ve been waiting for this for some time now. And 4K video streaming has already begun at Netflix and Amazon. But Ultra HD BD is finally out of the gate, although you won’t see it until the fourth quarter of this year. Streaming rates will be on the high side of 100 Mb/s with single and dual-layer discs available. (And yes, high dynamic range will be a part of the equation!) Panasonic showed their prototype of an Ultra HD Blu-ray player at the show. The question is; with all the enhancements coming to streaming, does optical disc matter anymore? Time will tell…
Circular LCD Displays: This was a breakout year for oddball sizes of LCDs, particularly in the Sharp booth where automotive displays were shown. (LG Display also exhibited circular and curved LCD displays.) Given the drop in TV prices and Sharp’s ever-dwindling market share in TVs, the market for automotive and transportation displays may be a better bet, long-term. Especially given the company’s leadership in implementing IGZO TFTs, which are important for brighter displays with lower power consumption and higher pixel density.
USB Type-C Connectors: VESA had an excellent demo of this game-changing connector, which has a symmetrical design (no need to worry about which way you’ve plugged it in) and can multiplex DisplayPort 1.3 video with high-speed data. USB 3.1 Type-C is seen as the next generation of USB connectors for mobile and portable devices, and by itself, it can move serial data at 10 Gb/s.
SiBEAM Snap Wireless Connectivity: Silicon Image has revived the SiBEAM name (they bought the company in 2011) and implemented their 60 GHz wireless display connectivity into a close-proximity variant. You simply bring two Snap-equipped devices together (like a smartphone or tablet and a matching cradle), and voila – you’ve established a full bandwidth data and display connection that can run up to 12 Gb/s. Plus, the connector can be used for wireless charging.
SI is showing integrated Snap transmitter and receiver chips that would replace USB 2.0 or 3.0 connections. Clearly, they are also targeting USB interfaces that support DisplayPort 1.3 (see USB 3.1 Type-C) and trying to move away from physical display connections. (This was one argument against using MHL to connect to televisions.) But if they’re successful, what happens to MHL? And now that Super MHL has been shown, what happens to conventional HDMI? Stay tuned..
Super-wide, high resolution desktop monitors: Seems like everybody had one of these at the show. HP, Dell, LG Display, Samsung, and others showed 27-inch widescreen displays with “5K” resolution (5120×2880 pixels). These monitors also support wider color gamuts and use 10-bit panels (a necessity, given all the 10-bit RGB images they’ll be asked to display). What’s surprising is how inexpensive these monitors are – HP’s Z27Q version will be available in March for just $1300.
Toshiba Glass: The jury’s still out on whether Google Glass is a hit or a bust (I’m leaning toward the latter). But Toshiba, who recently retrenched their television operations to Japan, is all-in with a line of enhanced glasses that employ a tiny projection module to show images on the lens surface. This has been tried before – Epson’s Moverio VR glasses have tiny QHD LCD panels embedded in them – and it remains to be seen if the public will buy into the idea. They do look stylish, though. (And there’s even a pair of safety goggles in the line.)
I’ll close out this report with a few passing thoughts. First, it’s impossible to miss the trends of mass-produced, cheap consumer electronics that are starting to turn CES into the old Comdex show. (And we all know what happened to that show!) Next, there is hardly any new technology debuting at the show that multiple manufacturers have in short order (and that includes the Chinese).
Whereas voice recognition was big a few years ago, gesture control took its place the past couple of years. But now that Omek (bought by Intel) and PrimeSense (bought by Apple) are absent from the scene, voice recognition has come back. My new Galaxy 5 phone has Samsung voice on it and it works reasonably well. However, it appears that consumers just haven’t jumped on the gesture recognition bandwagon yet.
Remember 3D? I almost got all the way through this report without mentioning it. A few companies still showed it, such as LG, Toshiba, HP, Hisense, Changhong, Ultra D (digital signage), Panasonic, and some gaming companies. Likewise, Google TV was gone this year, replaced by Android TV in such places as the Sony booth. Aside from program guide searches, I’m not convinced that the average TV viewer needs a Google search engine or Android OS on their TV. But I could be wrong.
Remember drones? I almost managed to skip them as well. There were so many at the show, ranging from behemoths that idled in place overhead while we visited tables at Digital Experience to pocket-sized models with built-in cameras that could zip unobtrusively over a crowd under the control of your smartphone. (I’m waiting for the first pocket-sized EMP generators to appear next year – like electronic bug-zappers.)
Finally, after a day full of press conferences during which there was only about 30 minutes of actual, usable news, I’d like to see a temporary moratorium placed on the words “innovation,” “big data,” “stunning,” “cloud,” “ultra” anything, and in the Chinese booths, “happiness.”
The only thing stunning about Vegas is how expensive cab rides have become. True happiness can only be found at Big Daddy’s Barbecue outside the Central Hall (dee-lish!). “Big Data” should be the name of a blues band, or at least the harmonica player. (Maybe Big Data and The Cloud?)
And I’m sorry, but a floor-mounted pet camera and toothbrushes that sync up to video games are not “innovation.” Cute, yes, but no innovative. (Although the self-powered skateboard I saw that can run up to 16 miles might fall into that category…)
