Product Review: Mitsubishi HC9000 Diamond 3D Projector

While 3D TVs have been available for over a year, the first crop of 3D front projectors are shipping now. The models I’m aware of use either digital light processing (DLP) or liquid crystal on silicon (LCoS) imaging technologies, and all of them are engineered to operate with active shutter glasses, with the exception of LG’s $15,000 CF3D, which works with passive eyewear.

Mitsubishi’s HC9000D has been in development for the better part of a year, and I had the chance to see it in the prototype stage a few times prior to this review. Those earlier versions were underpowered, making the 3D footage they projected unusually dark.

Now, Mitsubishi has started shipping a fully-powered chassis with some interesting bells and whistles inside. It comes with power zoom, focus, and lens shift, plus multi-step gamma correction and a two-position IR emitter for synchronizing its active shutter glasses.

Figure 1 – The HC9000D is definitely a ‘looker!’

OUT OF THE BOX

This is not a small projector, nor is it particularly light at 32 pounds. But it does have that cool gloss black finish that disappears into the darkness, plus an aerodynamic housing with all of the connectors along the left side, and not in the back.

The imaging engine for the HC9000D may be a surprise to you: It uses three .61” SXRD LCoS chips, just like the previously-mentioned LG CF3D and of course, both of Sony’s 3D front projector offerings. This is Mitsubishi’s first foray into reflective imaging, and LCoS offers a much lower cost than 3-chip DLP engines.

3D projectors need lots of light to overcome all of the polarization losses in active shutter glasses, so Mits has equipped the HC9000D with a 230-watt short-arc lamp. The supplied zoom lens has a ratio of 1.8:1, adequate for any home theater set-up as it easily lit up my Da-Lite Affinity 92” screen at a distance of 12 feet.

The input connectors include a pair of HDMI 1.4a inputs that also support ten different standard digital computer resolutions, and there’s also an analog VGA PC input connector for everything from 640×480 to 1080p/60. Mitsubishi has also provided a single component video (YPbPr) input, plus composite and S-video jacks. (Question: Why are manufacturers still supporting composite video on high-end 1080p projectors?)

The interface panel is rounded out by a pair of 12V triggers for powered screens and anamorphic lens adapters, an RS-232 jack for remote control, and another DIN jack that connects to the EY-3D-EMT1 IR emitter through a short (1 meter) or long (15 meter) cable. The emitter can be attached to the lower front panel of the projector, or positioned under your projection screen.

The supplied remote control is identical in function to all previous Mits remotes (I inadvertently turned on my Mits HC6000 a few times with it), except that it has a black housing. You can directly access any input, jump to preset picture modes, operate the powered lens functions, and step through the iris settings. The only exception is that the STANDBY button now toggles between 2D and 3D display modes.

MENUS AND ADJUSTMENTS

Mitsubishi 3LCD projectors are known for high image quality and part of the reason is the detailed menus provided for in-depth calibrations. That protocol continues with the LCoS-powered HC9000D. Four different picture preset modes (Cinema, Video, 3D, Dynamic) are provided for viewing, along with three USER memory slots.

Gamma correction is also possible through five presets (Cinema, 2.0, 2.1, 2.2, 3D, and USER), and the USER gamma adjustments offer detailed adjustments of white, red, green, and blue at 15 grayscale steps. That is a tremendous amount of tweaking at your fingertips, if you are that fanatical about precise gamma response.

Color temperature and white balance adjustments are also available for each USER mode, or you can select from one of six presets, including 5800K, 6000K, and 6500K. None of these are completely accurate, but will get you into the ballpark. There are also a set of color management controls for all six primaries that I suggest you avoid playing with, as they don’t exactly work as intended in their current implementation.

The menu complement is rounded out with three different levels of black set-up (0, 3.75, and 7.5 IRE), a ‘cinema filter,’ 3:2 frame rate conversion or ‘true’ (native) frame rate selections, and various adjustments for noise reduction and detail enhancement. The former will soften the image to hide digital noise artifacts, while the latter may enhance edge transitions too much. I’d leave ‘em both off if possible.

The HC9000D also has image warping software (referred to in the owner’s manual as ‘Anyplace’ control) built-in. It lets you re-map the pixels on a projected image to correct for off-axis projection, such as a severe high and wide angle. While it works quite well, it does impact image resolution as it decimates pixels to correct for trapezoidal distortion. (It can also fix lens distortions like barreling and pincushioning.)

You are much better off mounting the projector as close to the optical centerline of the screen as possible, and using the lens shift controls to move the image into position. Try to avoid any adjustments that manipulate pixels to correct for geometry!

The HDMI inputs have their own sets of tweaks. You can manually select the HDMI color depth (4:2:2, 4:4:4, or RGB), or let the projector configure it for you. There are also four different HDMI inputs modes – Auto, Standard, Enhanced, and Super White.

It’s best to leave this setting in Auto, as it will pick the correct color bit depth for each connected input. Enhanced is usually selected for PC input connections, but I have no idea what ‘Super White’ is intended to do: The manual just says, “Select when solid white occurs.” Any guesses?

There are also a few useful 3D image adjustments. The only 3D mode that is detected automatically by the HC9000D is the Blu-ray 1080p/24 frame-packing format, so called because it packs both left eye and right eye video into a single BD frame with 45 pixels of blanking for a total of 1920×2205 pixels. On the other hand, the so-called ‘frame compatible’ 3D formats (also known as ‘half-resolution’ formats) must be selected manually in the 3D menu, and include top+bottom (720p) and side-by-side (1080i).

You can compensate for light attenuation through polarization losses by boosting projector brightness in five steps, with 5.0 being the default setting. The sync pulse for active shutter glasses can also be reversed if needed in this menu. Normally, you should not need to play with either control (and as you’ll find out, a brighter screen will do you more good than the 3D brightness compensation settings!).

The last control I should point out is the ever-present Iris adjustment. Dynamic iris controls are de rigueur for LCD and LCoS projectors to drop black levels and improve contrast on low-level video content. I have never liked these adjustments because of the non-linear effect they have on gamma curves, and prefer to leave them off and just work with whatever dynamic range the projector manufacturer brought to the table – which isn’t as bad as you might think most of the time.

If you must use the iris settings, you have four different presets (Open, 3, 2, and 1), plus 18 steps of irising in the User menu. My advice? Set your black levels correctly and adjust the contrast for best dynamic range, and just live with it. In 2D mode, the black levels may be a bit higher than you’d want, but in 3D mode, you won’t see them anyway with the glasses on.

ON THE TEST BENCH: 2D

For my tests, I used a combination of SpectraCal’s CalMan V4.4 software and ColorFacts 7.5 to take all readings through Spyder 2 and Eye One Pro sensors. All of my calibrations were done in 2D mode, as I was most interested to see what the projector did to these settings when switched into 3D mode.

All 2D test patterns were generated by an AccuPel HDG4000, while my 3D test patterns were custom-created in Photoshop and played back @ 1280×720 resolution from a Toshiba M645 laptop computer, using the top+bottom frame compatible format. Additional 3D content came from Samsung’s Blu-ray test disc and 3D Blu-ray movie clips from Avatar and How to Train Your Dragon, played back on a Samsung BD-C6900.

You will be surprised at how little tweaking you’ll need to do to get a stable grayscale out of the HC9000D. After minimal calibration, I measured 2D brightness at 635 lumens with a center color temperature of 6542 degrees. That color temperature reading varied by a maximum of just 230 degrees over nine points of measurement. So far, so good!

Brightness uniformity was lower than I expected at 69% to the average corner from center, and 55% to the worst corner. That’s bordering on hot-spot territory, as 50% is a drop of one full f-stop in brightness. Contrast measurements were much better than you’d expect with the iris off, coming in at 279:1 ANSI (average) and 538:1 peak. While those numbers aren’t as impressive as what JVC’s achieved with their wire grid dichroic design, they are still respectable for any other LCoS projector.

I mentioned earlier that Mitsubishi always does a superb job with grayscale and color temperature performance. Figure 2 shows an almost-perfect 2.3 gamma curve after calibration that’s as good as any I’ve ever seen on the best projectors. (And it was measured with the iris disabled.)

The secret? Very tight tracking of red, green, and blue levels at each luminance measurement. You can see just how tight those levels track in Figure 3, which is the RGB histogram for the target color temperature setting of 6500 Kelvin.

Figure 2 – The HC9000D produces a nearly-perfect 2.3 gamma curve after calibration.

Figure 3 – This RGB histogram shows tight tracking of red, green, and blue across the entire grayscale.

The HC9000D has a ‘ginormous’ color gamut, which (unfortunately) cannot be dialed back accurately. That means the colors you’ll see off Blu-ray discs and other HD content will be over-saturated. The color management controls will not help you here – de-saturating a color will result in incorrect display of other secondary colors.

The correct approach is to set the exact color coordinates at the factory for RGB and CMY, based on the standard used to master the content being viewed, something very few projector manufacturers bother to do. Figures 4a-b shows the full color gamut of the projector compared to the BT.709 HDTV gamut and P3 digital cinema gamut.

Figure 4a – The HC9000D’s mapped color gamut, compared to the BT.709 HDTV color space.

Figure 4b – And here’s how the HC9000D’s color gamut compares to the P3 digital cinema color space.

ON THE TEST BENCH: 3D

All well and good – the HC9000D is a top-notch 2D projector – but what happens in 3D mode? For starters, let’s see what happens when switching from 2D mode to 3D mode with glasses off and on.

To measure the changes in brightness, I placed a Minolta CL200 directly in front of my projection screen to take an incident light reading from the projector for this test. I started with a baseline (glassless) reading of 1124 lux and a measured color temperature of 6190K – a bit on the warm side. With 3D mode enabled on the projector, but no glasses in place, the readings changed to 1137 lux (3D brightness @ 5.0) and 6093K.

After positioning Mitsubishi’s active shutter glasses in front of the CL200’s sensor, brightness readings dropped to 419 lux with a color temperature of 6576K. Finally, I turned the glasses on, and saw brightness drop to 146 lux while the measured color temperature soared to 8529K. (Switching the lamp from its normal setting into HIGH mode increased brightness slightly to 66 lux.)

That’s quite a decrease! Comparing the final 3D reading with glasses to the calibrated 2D reading without glasses, the amount of light that finally makes it to your eyes has decreased by about 87%

So, what’s the solution? You will need a higher-gain screen to enjoy 3D images from the HC9000D, as it’s just not bright enough for viewing on low-gain screens with active shutter glasses – at least, not at the projection distance I use. I dusted off an older 82” Vutec SilverStar (6.0 gain) screen, and it made a world of difference with the HC9000D.

Here’s the conundrum: A high-gain screen doesn’t match up well to the projector’s 2D mode, as it will elevate black levels. Does that suggest you’ll need two screens? Maybe not, as Stewart Filmscreens just announced a combination 2D/3D screen that’s supposedly optimized for both modes. (They call it “5D” – I kid you not!)

IMAGE QUALITY

2D image quality is top-notch, as you’d expect with a projector using an HQV Reon processor. The adjustable frame rates are used to convert 24 fps filmed content to 96 Hz (quad refresh), while 60 Hz video is doubled to 120 Hz. Scaling of 720p content to 1080p is seamless and de-interlacing of 1080i channels showed absolutely no motion errors. The projector’s dynamic range is excellent (within the limits of its black levels) and my only complaint is that colors pop too much, for reasons I explained earlier.

You could be very happy just running this projector in 2D mode. In 3D mode, it’s a different story. Most of the content I looked at on my Affinity screen was too dark when viewed in 3D mode and exhibited desaturated colors with low contrast.

The Vutec gain screen helped considerably, but this projector needs to be cranking out at least 300 – 400 3D lumens after calibration to work with my screen type, size, and projection throw. If you reverse-engineer the numbers, that means almost 3000 lumens in calibrated 2D mode.

The best 3D scenes were observed with the daytime flying sequences in Dragon and the final attack sequences in Avatar. On the Vutec SilverStar screen, they punched up considerably with improved color saturation, and the viewing experience was quite enjoyable. The 24-96 fps frame rate conversion provides a smooth, bright image with absolutely zero flicker.

One problem I noticed was crosstalk in each lens. This popped up when the glasses were tilted even slightly, with the effect more pronounced in high-contrast scenes. For 3D to present correctly; crosstalk in the glasses has to be kept to a minimum. Otherwise, you will begin to feel eyestrain and may develop a headache after sustained viewing.

For comparison, Sony’s 3D active shutter glasses suffer from crosstalk problems because only one polarizer is used, while Samsung and Panasonic glasses use two polarizers and are much better at suppressing crosstalk. The Mitsubishi glasses also use dual polarizers, but their ‘extinction ratio’ isn’t as good as I would have expected. Figures 5a – 5d show sample 3D images where crosstalk is strongly evident and not quite as evident.

Figure 5a – This 3D text chart shows crosstalk (ghost images) around the letters and vertical lines.

Figure 5b – A ghost image of the center circle can be seen clearly in this photo.

Figure 5d – Subtle ghost images were seen along the edges of the mountains and the dragon’s wings.  (Image © 2010 Dreamworks Animation)

You will clearly see double images in the test patterns, but the ghosting isn’t quite as apparent with the stills from Dragon. But it is there, along the jagged rocky cliffs and other background objects. It all depends on the angle of your head – if you tilt your head to either side, the effect becomes more pronounced. Ghosting is readily apparent with credits and other high-contrast text and symbols.

CONCLUSIONS

Mitsubishi’s HC9000D is a top-notch 2D projector, but underpowered for 3D with low-gain screens. It calibrates quickly and performs nicely, but those calibrations will shift noticeably when viewing with 3D glasses. You’ll definitely need a gain screen with this projector for 3D content, and it might be a good idea to choose one that has a slightly warm color temperature that will offset the higher color temperature in 3D mode.

More horsepower under the hood would help. As I mentioned earlier, something in the neighborhood of 3000 lumens would be required to (a) perform a full 2D calibration and (b) provide enough illumination in 3D mode to low-gain (1.0 to 1.3) screens in the 82-inch to 102-inch range, assuming  a projection distance of 10 – 12 feet.

However, if you are sitting closer to a smaller screen, then you will be in better shape: The HC9000’s measured light output after calibration should be adequate for 3D viewing on a 72-inch screen at a distance of 6 to 8 feet, as you will wind up with 3x to 4x brighter images. And you DO want to sit closer to 3D screens to get the maximum impact: My recommended seating distance is 1x to 1.3x the screen diagonal measurement. That will make the 3D images fill 50% or more of your field of view, and give you that theater-like immersive experience!

NAB 2011: It’s All About Streaming, Displays, and Connectivity

With each passing year, NAB looks less and less like a broadcaster’s show and more like a cross between CES and InfoComm. It’s a three-ring circus of product demos, panel discussions, conferences, and media events that all points to the future of ‘broadcasting’ as being very different than what it was at the end of the 20th century.

 

Officially, slightly less than 90,000 folks showed up to walk the floors of the Las Vegas Convention Center, and it was elbow-to-elbow in some exhibits. But there was another trend of smaller booths for the ‘big name’ exhibitors like Panasonic and JVC.

 

That reflects the reality of selling products that have mostly three and four zeros in their price tags. At my first NAB in 1995, it wasn’t unusual to see $50,000 cameras and $80,000 recorders. Now, you can buy some pretty impressive production cameras for about $5,000.

 

Streaming and over-the-top video was big this year. Ironically, NAB featured an enormous streaming media pavilion back in 1999, but it vanished the next year. The reason? A lack of broadband services across the country that could support streaming at reasonable bit rates.

 

Obviously, that’s all changed now, what with Netflix at 21 million subscribers and climbing, and MSOs deploying multi-platform delivery of video and audio to a plethora of handheld devices. Concurrently, the broadcast world is trying to roll out a new mobile handheld (MH) digital TV service to stand-along portable receivers and specially-equipped phones.

 

And behind all of this, the FCC continues to make noise that it wants to grab an additional 100 – 120 MHz of UHF TV spectrum to be repurposed for wireless broadband, a service you’ll have to pay for. Attendees had mixed thoughts on whether the Commission will actually be able to pull this off – there is some opposition in Congress – but there appeared to be a high level of opposition to the plan, considering there is plenty of other spectrum available for repurposing, much of it already used exclusively for government and military purposes.

 

Like last year, there were lots of 3D demos, but the buzz wasn’t really there. 3D still has a ways to go with its roll-out and it simply can’t compete with the interest in content delivery to smart phones, tablets, and other media players. Still, there were some cool 3D products to be found here and there.

 

Here are some of the highlights from the show.

Is that an MH receiver in your pocket, or are you just glad to watch DTV?

ATSC MH Pavilion – several companies exhibited a range of receivers for the MH services being transmitted during the show from Las Vegas TV stations and low-power rigs in the convention center. LG and RCA both showed some snazzy portable MH receivers, with LG’s exhibit putting the spotlight on autostereo 3D MH (as seen at CES) and a service call ‘Tweet TV’ which would allow viewers to comment on shows they’re watching and have those tweets appear on their MH receiver.

 

Another demo had CBS affiliate KLAS-DT transmitting electronic coupons for local retailers and restaurants during the show. These showed up on a prototype full-touch CDMA smart phone with a 3.2” HVGA screen.

 

In a nearby booth, RCA unveiled a lineup of hybrid portable DTV receivers. There are two 3.5” models (DMT335R, $119, and DMT336R, $159), a 7” version (DMT270R, $179), and a pocket car tuner/receiver that connects to an existing car entertainment center. It will sell for $129.

Believe it or not, this was a commercial for Coca-Cola.

Motorola had two intriguing demonstrations. The first showed full-bandwidth 3D content distribution, using the full 38.8 Mb/s bandwidth of a 256 QAM channel to transport frame-packed 1080p video with full 1920×1080 left eye and right eye images, encoded in the MPEG4 H.264 format and sequenced through active shutter glasses.

 

Nearby, an HD video stream was encoded for four different displays, with all four signals carried simultaneously in the same bit stream. First up was a 1080p/60 broadcast; next to that a 720p/60 version, followed by a standard definition version (480i) and a version sized for a laptop computer or tablet. Both MPEG2 and MPEG4 codecs were used.

 

Red Rover attracted quite a crowd with their 28″ 4K (3840×2160) 3D video monitor which uses two 4K LCD panels arranged at 90-degree angles to each other (one on top, facing down). A half-mirror with linear polarization is used to combine the left and right eye images for passive viewing. Both LCD panels are Samsung vertically-aligned models, and the whole works will sell for (ready for this?) $120,000.

Only $120K? That's a steal!

Volfoni showed dual-purpose 3D glasses at NAB. When powered on, they function as active shutter eyewear. Powered off, they are usable as passive 3D glasses. The whole shebang is controlled by an external power pack the size of an iPod nano that clips to your pocket or shirt, and this ‘pod’ can ‘learn’ any IR code from active shutter TVs.

 

The pod controller can step through several neutral density filters and there are several levels of color correction possible from the remote power pack. (Electronic sunglasses – imagine that!) The glasses use 2.4 GHz RF signaling technology to synchronize with any active shutter monitor or TV. And despite all of the bells and whistles, they weigh just over an ounce.

 

Sony’s 17″ and 25″ BVM-series OLED monitors that were first shown at the 2011 HPA Technology Retreat now have siblings. The PVM-E250 Trimaster OLED display is structurally the same as its more-costly BVM cousin, but has fewer adjustments and operating features. And it’s going to sell for quite a discount over the BVM version – just $6,100. There’s also a 17-inch version which wasn’t operating at the show, and it is expected to retail for $4,100.

 

Up at the front of the Central Hall, Panasonic was showing the TH-42BT300U, their first plasma reference-grade monitor. It’s not all that different from the exiting 20-series industrial plasma monitors in appearance, but there’s a big difference in operating features. Black levels have dropped and low-level noise has been minimized with a half-luminance PWM step. This results in more shades of gray and a smoother transition out of black.

 

In addition, the TH-42BT300U supports 3D playback for side-by-side and top + bottom color and exposure correction. Panasonic has also added automatic ’snap-to’ color space menu options, along with a user-definable color gamut option. When calibrated, it was an eye-catcher. There’s a 50-inch version also in the works, and both monitors will go on sale this fall.

Sony knows OLEDs. Make. Believe. (Nah, it was real...)

Panasonic's TH-42BT300U (left) maps color accurately to the BT.709 color space, unlike its sibling the TH-42PF20U (right).

Hyundai unveiled the B240X, a new 24″ passive stereo LCD monitor. It sports a 1920×1200 display with circularly-polarized film-patterned retarders and supports 3D side-by-side and top + bottom viewing formats. The pixel pitch is about .27 mm and brightness is rated at 300 nits. Hyundai also created an eye-catching 138″ (diagonal) 3×3 3D video wall for NAB, using its flagship S465D 46″ LCD monitor.

 

Sisivel has come up with a unique way to deliver higher-resolution 3D TV in the frame-compatible format. Instead of throwing away half the horizontal resolution for 1080i side-by-side 3D transmissions, Sisivel breaks the left eye and right eye images into two 1280×720 frames. The left eye frame is carried intact in a 1920×1080 transmission, while the right eye is broken up into three pieces – the top 50% of the frame, and two half-frames that make up the bottom.

 

All of this gets packed in a rather unusual manner (see photo), but some simple video processing and tiling software re-assembles the right eye fragments into one image after decoding. Then, it’s a simple matter to sequence the lefty eye, right eye images as is normally done. The advantage of this format is that it has higher resolution than ESPN’s top+bottom 3D standard (two 1280×360 frames).

So THAT's how you pack two 1280x720 3D frames into a 1920x1080 broadcast. Clever, eh?

 

JVC announced two LCD production monitors at NAB. The DT-V24G11Z is a 24-inch broadcast and production LCD monitor that uses 10-bit processing and has a native resolution of 920×1200 pixels. The extra resolution provides area above and below a 1080p image for metering, embedded captions, and signal status. The incoming signal can also be enlarged slightly to fill the entire screen.

 

The DT-3D24G1Z is a 24-inch passive 3D monitor with circular polarization patterned films. It has 1920×1080 pixel resolution, 3G HD-SDI and dual-link inputs, a built-in dual waveform monitor and vectorscope, left eye and right eye measurement markers, and side-by-side split-screen display for post production work including gamma, exposure, and color/white balance correction.

 

Nearby, crowds gathered to see two new 4K cameras that use a custom LSI for high bitrate HD signal processing. The demo used a Sharp 4K LCD monitor, and the cameras were running at 3840×2160 resolution. They have no model numbers or price tags yet.

 

Ikegami’s field emission display (FED) monitor that attracted so much attention a few NABs ago, but was written off when Sony pulled out its investment from the manufacturer, is now back. Its image quality compared favorably with Sony’s E-series BVM OLED monitors, and the images displayed with a wide H&V viewing angle and plenty of contrast pop. It was being used to show images from a Vinten robotic camera mount at NAB, and no pricing has been announced.

Forget the Canon SED, Ikegami's got an FED! (A 'what?')

Dolby showed their PRM-4200 42-inch HDR LCD reference monitor at NAB. While this product is not new, there was a substantial price cut announced at the show to $39,000.  Initial comments from the post production community have indicated the price is too high for today’s economic environment. As a result, Dolby has apparently sold a few to video equipment rental houses for location and studio production work.

 

Digital SLRs are being used to shoot TV productions such as “House” and independent films, and they could use a couple of good monitors with hot shoe mounts. Nebtek had a 5.6” model at the show, as did TV Logic. Both models sport 1280×800 (WXGA) resolution, compatibility with HD-SDI and HDMI inputs, and have on-screen display of waveform/vectorscope details, focus assist, and chroma/luma signal warnings. Embedded audio from the cameras’ HDMI output can be displayed on screen, and there are several scan and pixel mapping modes.

 

One of the more significant announcements at the show – at least, at first reading – was Verizon’s Digital Media Services. The idea is to serve as an electronic warehouse for everyone from content producers to digital media retailers – in effect, an Amazon e-commerce model, except that Verizon wouldn’t sell anything; merely ‘warehouse’ the assets and distribute them as need to whomever needs them.

 

Numerous companies showed real-time MPEG encoders, among them Z3 Technology, Visionary Systems, Haivision, Vbrick, Adtec, Black Magic Designs, and (of all people) Rovi, otherwise known for their electronic program guide software. Many of these encoder boxes can accept analog video (composite and component) as well as HDMI and DVI inputs. The general idea appears to be ‘plug-and-play’ encoding for IPTV streaming across a broad range of markets. The Black Magic encoder was the cheapest I’ve seen to date at $500, while price ranges on other models ranged as high as $9,000.

A Tektronix monitor for color anaglyph 3D? REALLY?

Do NOT let your children get any ideas from this photo...

Tektronix had one of the funnier (unintentionally) demonstrations of test and monitoring gear. A new combination monitor, the WFM300, has a color anaglyph mode where you can see the interocular distance for red and cyan color anaglyph program material. Never mind the fact that color anaglyph isn’t being used for much of anything except printed 3D these days, so what were the folks at ‘Tek’ thinking?

 

Finally, Sony showed they can be all wet but still on top of things with their demonstration of an HXR-NX70U 1080p camcorder operating normally while getting a pretty good hosing. The camera is completely water-sealed and dust-sealed for use in hostile environments, and records to internal hard disc drives and memory cards. The shower ran continuously during the show and the camera never even hiccupped. Fun stuff!

One Size Fits All

Yesterday, Panasonic and XPand announced that they have developed M-3DI, which is intended to be a new interoperability standard for active shutter 3D glasses.

 

M-3DI is actually a communications protocol used to signal and sequence the glasses in step with the rapid flashing of left eye and right eye 3D images. Until now, you couldn’t use one manufacturer’s brand of active shutter glasses to view another manufacturer’s TV, due to different signaling codes. Panasonic AS glasses do work with 2010-vintage Samsung 3D TVs, but that was the exception.

 

This incompatibility problem was one of the reasons consumers cited for holding off on 3D TV purchases last year. It will still be an issue for Samsung TVs in 2011, as the new line employs the Bluetooth communications protocol instead of infrared linking.

XPand announced last year that they would come out with so-called “universal” active shutter glasses that could learn IR signaling codes, just like a universal TV remote control does. But this announcement takes things a step further by ensuring greater support among multiple manufacturers, including Changhong Electric Co., Ltd., FUNAI Electric Co., Ltd., Hisense Electric Co., Ltd., Hitachi Consumer Electronics Co., Ltd., Mitsubishi Electric Corporation, Seiko Epson Corporation, SIM2 Multimedia S.p.A. and ViewSonic Corporation.

 

What really caught my eye in the press release was this statement: “The technology will let consumers enjoy the immersive 3D experience across all types of compatible 3D displays as well as at movie theaters, with a single pair of 3D active-shutter eyewear.”

 

Currently, movie theaters do not use active shutter viewing systems as the cost of glasses would be prohibitive – and they’d break down pretty quickly. Apparently, Panasonic has plans to expand into that arena, possibly with their line of high-brightness digital cinema DLP projectors, but we’ve not heard any details previously.

 

The M-3DI standard will also cover active shutter eyewear for computer monitors and front projectors for home theater and commercial AV applications.  But the big question remains: Will the other major players in active shutter 3D (Samsung and Sony) come aboard?

 

Rumors have abounded that Sony may add passive 3D TVs to their product line in the near future, something that will no doubt be influenced by LG’s success – or lack of it – with their new passive Cinema 3D TV line.

 

Regardless, this announcement is long overdue. And Samsung and Sony really ought to join the parade if only to help 3D TV sales pick up some momentum.

CES 2011: Afterthoughts

CES is a strange show. It’s so big and has so many exhibitors that you keep thinking about what you’ve seen for weeks afterwards – kinda like mental ‘aftershocks’ and flashbacks. And I’ve had a few of those since returning home almost a week ago.

Here, in no particular order, are some afterthoughts from CES:

It looked much more impressive than it worked.

Gesture Recognition – Hey, Where’d it Go? In 2007, 2008, and 2009, gesture recognition for TV operation was a BIG deal at CES. Hitachi, Toshiba, JVC, and others all showed sophisticated gesture-recognition systems at previous CES shows, and last year’s Toshiba exhibit managed to combine GR, their Cell processor, and 3D in a most impressive demonstration.

This year? Hardly any GR demos at all, aside from some rather crude examples found in the Hisense and TCL booths that barely worked. The TCL demo was so insensitive that visitors to that particular exhibit looked like they were swatting at flies, while the Hisense demo consisted of someone doing a work-out while following an animated trainer on a nearby LCD TV.

Yawn…

OLED TVs are coming any day now. About the same time the Cubs win the World Series.

OLEDs – We’re Still Waiting: Every year, Samsung, Sony, LG, and others tease us with demonstrations of gorgeous-looking OLED TVs in a variety of screen sizes. Yet, we continue to wait, and wait, and wait for production models to come to brick-and-mortar stores. (The XEL-1 doesn’t count.) Sony even built an autostereo screen into a 24.5-inch AM OLED display, while Samsung’s 19-inch AM OLED was 50% transparent.

We’d all like to replace our LCD and plasma TVs with OLEDs, but it looks like we’re going to be drooling and waiting a LONG time before that happens. Smart phones have already beaten us to the punch and it looks like tablet computers will be the next place to roll out (literally) OLED screens.

And yet, every year, we get our hopes up again…

These must be figments of my imagination.

Picoprojectors: Vaporware? After reading a recent Display Daily post by colleague Matt Brennesholtz at Insight Media, I fired off an email to eight different IM analysts, asking them if they had ever seen a picoprojector in use in 2010 other than at a trade show or a display technology conference.

This may surprise you, but each one of them responded with a simple, “No.” None of them had spotted any at retail, either. And yet, companies like Pacific Media Associates continue to issue optimistic sales forecasts for picoprojectors, while Texas Instruments had a full suite of “picos” at CES that were built into smart phones, a tablet computer, cameras, and pocket projectors.

I think tablet computers may derail picoprojectors, or obsolete them completely. How about you?

Maybe they didn't get the memo last year?

Hey Sharp, 3D was SO 2010! Sharp once again had an enormous CES booth filled with big, colorful LCD TVs (70-inches was the big news this year) and finally had a few 3D Blu-ray demos to go with them. Well, a year late isn’t too bad, I guess. The only problem is; Sharp’s share of the U.S. TV market has been steadily dropping since 2005 and is below 3%, according to NPD Display Search’s 3rd quarter 2010 numbers. That’s embarrassing! Even Panasonic now ships more LCD TVs than Sharp, who pioneered the LCD TV biz a couple of decades ago.

The four-color Quattron technology, while intriguing, doesn’t appear to have caught on with consumers so far, and we all know how disappointing sales of active shutter 3D TVs have been to date. To add to Sharp’s problems, Sony has not fully committed to fund its share of Sharp’s new Gen 10 LCD plant. Sony was originally on the hook for a 34% stake, but according to multiple reports may cap that investment at 12% and look to China for a cheaper source of LCD panels.

This would be a good time for a comeback, kid…

There's a contrarian in every crowd...

Mitsubishi Thumbs its Nose at the Experts: Yep, those ‘diamond’ guys are still making rear-projection DLP TVs, and apparently selling plenty of them, too. Their 92-inch roll-out at CES drew big crowds and will probably ticket around $5,000, which is less money than a decent front projector, screen, and home theater in a box will cost you. Did I say it could do 3D, too? Side-by-side, top+bottom, frame packing, checkerboard – you name it.

We “experts” predicted Mits would fall by the wayside as the LCD and plasma juggernauts rolled through the market. Uh, not quite. And with Mits’ new laser light engine, the issue of lamp replacement will eventually fade into the sunset. Texas Instruments is thrilled that they still have a RPTV customer, and as long as Mits can manage its bill of materials (BOM) costs, they can remain in the catbird seat for a few more years until something better comes along.

(Sound of a big raspberry coming from Irvine…)

DisplayPort: On Your Mark…Get Set…Get Set…Get Set: Is DisplayPort ever going to take off? I saw several cool demos of multi-monitor support and embedded 3D notebooks through DisplayPort in the IDT suite, along with a basic booth in the lower South Hall showing wireless DisplayPort over WHDI and a multi-channel audio concept demo.  But who’s using it, aside from Apple?

In the meantime, HDMI (Silicon Image) showed ViaPort (multiple connections to a TV hub and one to a AVR with automatic streaming for the highest-supported audio format), MHL (Mobile content through a mini HDMI interface to TVs and other devices), and ViaPort for digital signage (Blu-ray at full resolution to eight daisy-chained TVs through single HDMI connections).

Maybe they misplaced the starter’s gun.

What's next? VIZIO appliances? Cars? An Airline?

VIZIO – The Next Apple? Not only has VIZIO staked a big claim in the TV marketplace, they also rolled out a tablet computer and a smart phone at CES. The VIZIO Phone has a 4-inch display, GPS, WiFi, two built-in cameras, HDMI output (MHL), 2 GB of storage and doubles as a universal remote for VIZIO products.

The VIZIO tablet is pretty impressive, too. It also has WiFi, GPS, and a high-rez camera for videoconferencing, HMDI output, three internal speakers, and 2Gb of internal storage plus a MicroSD card slot. And yes, it can also work as a universal remote. The guys at VIZIO also thumbed their noses at all of the active-shutter 3DTV manufacturers and opted to go with passive 3D in a 65-inch LCD set that uses inexpensive RealD (circular polarization) glasses.

What’s next, Mr. Wang? Brick-and-mortar ‘VIZIO Zone’ stores in selected cities and malls? (Don’t laugh, he might just try it!)

Ghandi was into passive, too.

Active Shutter 3D – Has it Peaked Already? In addition to VIZIO, LG and JVC also showed new large LCD TV products with embedded micropolarizers and inexpensive passive 3D glasses. I saw a few passive demos here and there, but these were the big three as far a product rollouts. LG even had large bins with passive glasses at the numerous entrances to their booth.

While passive 3D certainly solves the problems with fragile and expensive glasses, it can play funny tricks with screen resolution as every other horizontal row of pixels has micro-sized circular polarizers that work in opposite directions. That can make the screen appear to have noticeable black lines on it when viewing normal content, a problem that would be solved by moving to 4K native resolution (thereby adding to panel complexity and costs).

Still, passive 3D could put a crimp in 3D TV sales this year as it feeds into the average consumer’s wariness of another TV ‘format war.’

Step Right Up and Getcha 3D Camcorder! This product category went from 0 participants in 2010 to “I lost count’ in 2011. Panasonic, Sony, ViewSonic, JVC – you name the company, they had a 3D camcorder out for inspection somewhere in their booth. And it wasn’t just the big boys, either. Ever hear of Aiptek? Didn’t think so. They showed a palm-sized 3D camcorder under their name that coincidentally appeared in the nearby ViewSonic booth.

 

Coming to a home near you! Check newspapers...

The question is how many of these cameras were using conversion lenses (Panasonic) and how many were capturing video through true 3D optical assemblies (JVC, Sony).  The Aiptek model in question may also have been converting 2D on the fly, but it was hard to tell from the sketchy details in their booth. Also, Sony’s and JVC’s cameras use the full-resolution frame-packing format, similar to Blu-ray DVD.

OK, who wants a 3D camcorder? (And a 3D TV to go with it?)

Wonder if their booth was open on Saturday?

Hey, Didn’t You Guys Just Lose $8.5B? Once again, the United States Postal Service occupied a healthy-sized booth in the upper South Hall. And once again, they were shilling for Priority and Overnight Mail, package shipping, and a new service called PremiumPostcard.com direct mail marketing.  They also featured something called the Fast and Furious Challenge, although no racecar was in sight this year.

Ordinarily, I’d be kinda upset that taxpayer money was spent this way…except that the USPS operates as a quasi-private agency, living entirely off revenues from mail delivery. So maybe I should instead give them props for trying to drum up more business, except that it’s hard to understand how many of the surrounding Chinese manufacturers would benefit from any USPS offerings.

As long as they don’t drop Saturday delivery, I guess I don’t care…

CES 2011: Applications? Plenty! Buzz? Ahhh, Not So Much…

How do you like THIS for a videowall?

If you still needed any convincing that the U.S. economy is on the rebound, the 30-minute-long cab line at McCarran Airport did the trick. Attendance at this year’s running of the world’s ultimate gadget expo was WAY up, probably hitting 2007 levels. (CES claimed 140,000 in attendance, but my guess is that the real number was more like 90,000 – 100,000, based on cab lines and traffic.)

But CES was a vastly different show than in recent years. True “wowza!” product demos were few and far between. Instead, what we saw were ‘apps’ – practical, real-world applications of technologies introduced in the past couple of years. (And of course, umpteen million tablet computers.)

Smart phones were huge this year, and they were doing everything from shooting videos to doubling as game controllers and even talking to ovens and refrigerators. The Android OS rules this space, with Windows coming up far behind. If there was a possible use for a smart phone, someone demonstrated it in a booth (including 3D).

Ever expect to see 3D on an MH receiver? Neither did I.

A wonderful moment, indeed.

Discussions of “the cloud” were heard in every hallway. For those readers who don’t know what “the cloud” is, it’s the concept of storing and accessing media files from remote servers, streaming or downloading it to view on portable and desktop displays. Netflix streaming is a good example of “the cloud,” and many industry analysts believe “cloud” delivery of content is where everything is headed – no more big hard drives or optical disc readers, just fast wireless and wired Ethernet connections.

Speaking or wireless, it’s all the rage. I lost track of all the wireless connectivity demos, ranging from wireless USB 3.0 docking stations to full-bandwidth 1080p video and multi-channel audio streaming to TVs from Blu-ray players, using the 6 GHz radio frequency band.

And those tablet computers…they were everywhere, so many that tablets suffered the ignonimous fate of moving from the most anticipated new product at the opening of the show to “so what?” products by its closing. I saw just as many off-brand and white label tablets in the lower regions of the South Hall as I did at the Blackberry, ViewSonic, Samsung, Sharp, Sony, and Panasonic booths. Can you say, “buzz kill?”

That's a complete nVidia workstation graphics card, connected through 6 GHz wireless links.

How does a Wireless USB 3.0 docking station grab ya? Samsung's got it.

3D TRENDS

Last year’s show was dominated by 3D. You couldn’t get away from it! This year, the 3D pickings weren’t quite as abundant, although a few companies (Sony and Panasonic) continued to place a heavy emphasis on stereoscopic TV viewing in their booths.

Toshiba did too, except they chose to emphasize glasses-free (autostereo) 3D exclusively in their booth. LG opted to show passive 3D products that use inexpensive circular-polarization glasses, along with a single autostereo LCD TV. Meanwhile, Sony had concept demos of a portable 3D Blu-ray player and a 24-inch autostereo organic light-emitting diode (OLED) TV.

The reduced emphasis on 3D might have something to do with the paltry sales of active-shutter 3D TVs in 2010. Sales numbers were nowhere near what anyone predicted, which could partly be blamed on the recession. But it could also be blamed on a perception that there is a format war brewing in the world of 3D TV (shades of the 1080i vs. 720p battles from ten years ago).

Toshiba's 15-inch prototype autostereo notebook display uses a built-in camera to adjust the 3D viewing angle to your position.

HELLO, 1958! Polaroid actually showed a blue-yellow anaglyph 3D demo at CES. (CAUTION: Don't watch Avatar this way...)

Toshiba’s recent announcements of glasses-free 3D TV certainly added to that perception, and that’s all they showed at CES. Meanwhile, LG and JVC seem to be leaning towards passive 3D (embedded polarizing filters) in their LCD TVs, and in fact LG had large baskets of passive 3D glasses available to both visitors.

The LG autostereo LCD TV worked about as well as the Toshiba models. As you change your viewing position, patterned film retarders (PFRs) built-in to the LCD surface create a new perspective and viewpoint, blocking some pixels and revealing others. It works, but you’ve seen the same effect before with static digital signage displays in retail stores and in airports. And it’s not easy to watch 3D video this way for very long.

There were plenty of autostereo handheld display demos. LG’s new Optimus smart phones were shown as game controllers for 3D gaming systems, but were also displaying mobile 3D content. Nearby, LG had a demonstration of autostereo 3D as broadcast from Las Vegas DTV station KLVX, using the MH mobile digital TV standard.

Sony showed an autostereo media player in its booth, along with the aforementioned portable Blu-ray player with autostereo screen. (Frankly, I think the market for portable BD players is pretty miniscule, but the autostereo images looked quite nice.)

Sony's 24.5-inch autostereo AM OLED was a show-stopper.

JVC's got some skin in the 3D game with this 65-inch passive 3D LED LCD TV.

Sharp, who last year missed the boat on 3D – and whose U.S. market share in TV sales continues to drop precipitously – rolled out the 3D bandwagon this year, with a full line of Quattron 3D TVs out for inspection, including a new 70-inch model. Hidden away in another part of their booth were demos of 3.8” and 10.6” autostereo LCD displays for handheld devices.

JVC, who has been concentrating more on projection products lately, unveiled their first consumer passive 3D TV. It’s a 65-inch, edge-lit LED model with embedded micropolarizers that work with RealD theater glasses. Back in the Central hall, Hisense, Konka, and TCL all showed Chinese-made 3D sets with active shutter glass technology, while VIZIO threw its hat in with the passive 3D crowd, unveiling several models that use embedded polarizing filters and passive eyewear.

Hmmm…maybe there IS something to this 3D format war, after all…

NETWORKED TVS

It was hard to find a TV at CES that didn’t sport some sort of Internet connection. Panasonic (VieraCast), VIZIO (VIZIO Internet Apps), Sony (Google TV), LG (Smart TV), and Samsung (Samsung Apps) all had full plates of NeTVs out for inspection, along with numerous connected Blu-ray players. By the way, the ‘connected’ part of Blu-ray players is the big reason they are finally selling so well, as consumers apparently can’t get enough of YouTube and Netflix streaming.

There were also plenty of demos of smart phone control of TVs, using WiFi to stream back a lower-resolution version of the content being displayed on-screen. I’m not really sure why anyone would need that functionality, especially if they are already sitting in front of the TV watching whatever program or movie is playing out. Maybe it’s just in case you need to run to the bathroom?

Don't have Internet connectivity on your plasma or LCD TV? LG's got the fix.

You want a TV remote? I'll show you a TV remote!

LG went everyone better with their ST600 Smart TV adapter. Remember ATSC set-top boxes from the DTV transition? Well, the ST600 is an Internet TV adapter that works with any set through its HDMI port.  It costs about $150, and gives you a Web browser, plus one-button access to popular Internet TV sites like Netflix, CinemaNow, VUDU, Hulu Plus, YouTube, MLB TV, Pandora, and others.

Sony prominently featured their Sony Smart TV product line, based on Google TV. This product has really stumbled out of the gate, probably because of the incredibly complex keyboard remote control (remember Web TV, anyone?) and the fact that a majority of Web video surfing can be accessed with directed one-button Hulu Plus, Netflix, and YouTube apps. Maybe we’ll see a simplified version of the product from Sony in 2011.

Panasonic rolled out its own tablet computer, as previously mentioned. The Viera Tablet is part of a “cloud” focused content delivery strategy (there it is, again!) that will let consumers access on-demand and VIERA Connect content. The tablet will actually be available in several different sizes, ranging from 4” to 10,” and also functions as a TV remote control.

Sharp also featured connected Blu-ray players, with directed apps for VUDU taking center stage. Three new models use wireless connections to access Netflix, VUDU, Pandora and YouTube content via streaming connections. They also took the wraps off a 70-inch Quattron LCD TV with built-in WiFi and a support for CinemaNow, Netflix, VUDU, and DLNA video streaming.

Sharp's got a new 70-inch LCD glass cut, and wireless Internet connectivity to go with it.

Samsung didn’t have quite as many sexy NeTV announcements, but they did have the largest LCD TV at the show (75 inches) and prominently featured their Smart Hub technology. You can access the usual suspects through wired and wireless Ethernet connections, along with Blockbuster, MLB.TV, AccuWeather, Facebook, Hulu Plus, and History Channel content, among others.

PROJECTION TRENDS

There wasn’t a lot of projector news from CES. Texas Instruments used the event to launch a new line of DLP Pico HD chipsets. These are tiny WXGA-resolution (1280×800 pixels) digital micromirror devices (DMDs) that are used in picoprojectors and pocket projectors, and there were plenty on display in the TI suite. They had picos running in GE digital cameras, Sharp smart phones, and even a prototype tablet computer.

Sony even showed a DLP-based picoprojector in a new digital camera at Digital Experience, an interesting development considering that both companies parted ways back in 1996 after Sony built its first and only SVGA DLP high-brightness projector.

Yes, Pico DLP chips really are that small.

Even digital cameras are equipped with picoprojectors nowadays.

Other picoprojectors were shown from LG, ViewSonic, Acer, and Optoma. The Optoma iPod docking station with built-in picoprojector was a clever product, as was the GE digital camera. But most of these projectors cast small, dim images, and you have to wonder how the explosion of tablet computers will affect this market, considering that both picos and tablets would be used for very small group presentations.

Several 3D projectors took a bow in Las Vegas. Mitsubishi finally has a model number for its LCoS 3D projector (HC9000), while Sharp announced the XV-Z17000 DLP 3D chassis. Samsung’s also got a new 3D box, the SP-A8000, which also uses DLP technology. Over in the JVC booth, the previously-announced DLA-X9 and DLA-X7 D-ILA (LCoS) 3D front projectors now have THX 3D certification – apparently the only models to earn that appellation so far. The general consensus is that DLP produces better blacks and higher contrast than LCoS 3D projectors, but that will remain to be seen. (I expect to have a review sample of the Mits unit in mid-March.)

Mitsubishi’s big screen TV division continues to hang on in the rear-projection DLP marketplace and is actually doing quite well, thank you very much. (It’s easy to capture 100% market share when you are the only player!) They launched a 92-inch DLP set with 3D compatibility, and while it doesn’t have a model number yet, expect it to sell in the mid-$5000 range, with active shutter glasses an extra.

Is a 92-inch 3D screen big enough for ya?

NO?? OK, then how about a 155-inch OLED screen?

WIRED VS. WIRELESS NETWORKING

I met with most of the major networking groups at CES. Two of them (HDBaseT and DiiVA) are very close in theory and practice, with structured wire being used to distribute video and audio between connected devices. Both systems also support USB connectivity for remote gaming control, and both systems can deliver power to connected devices (100 watts for HDBaseT and 24 watts for DiiVA).

Many commercial interface manufacturers are incorporating HDBaseT infrastructures into their AV switching products, the latest being Crestron (Digital Media) and Gefen. AMX already uses a version of HDBaseT in their AV switchers and distribution amplifiers.

DiiVA is apparently gaining popularity in China, where new apartment buildings and houses all have structured wire pulls. Most of the companies that have DiiVA-compatible products are also (not surprisingly) based in China.

Keep your eye on Diiva for both consumer and commercial applications.

A touch of the button is all it takes to get you in a surround-sound sweet spot, courtesy of Summit Semiconductor.

On the wireless side, Summit Semiconductor, Aeleron, and Amimon all showed system-on-chip solutions for high-bitrate video and audio distribution. Amimon is the founder of the Wireless High Definition Interface (WHDI) and showed wireless display connectivity to remote PCs, as well as Blu-ray 1080p playback to specially-equipped LG and Hisense wireless LCD TVs.

Aeleron featured Ultra WideBand (UWB) connectivity of 1080p streaming and docking systems that work with TVs, laptops, smart phones, and other media players. They also featured DLNA-compatible UWB adapters for in-room signal distribution (UWB can’t go between rooms) and driverless HDMI interfaces.

Summit’s demo was perhaps the most interesting. It featured uncompressed distribution of wireless multi-channel surround audio to randomly-placed powered speaker columns. A special remote activates a supersonic Doppler system that automatically adjusts the levels of all speakers so that you are sitting in t ‘sweet spot,’ no matter where you are in the room, or where the speakers happen to be placed. It takes all of ½ second for this adjustment to be made.

Back over in the Hilton, Sigma Designs has found a way to reduce line noise and broad spectrum interference in HomePlug systems. Turns out, all those battery chargers and AC adapters are pretty ‘dirty,’ which clips the available bit rate for moving video and audio through decoupled AC power lines. With the Sigma enhancements, the receive speed (to a media player or TV) is as much as 65% of the transmit speed (from the playout source). With normal HomePlug appliances, the receive speed can drop to as little as 20 – 25% of the transmit speed.

Who knew HomePlug systems were so noisy? (not to mention iPad AC power adapters...)

Guess what? Your smart phone can talk to your oven now. And your refrigerator, and washer, and dryer, and...WHAT??? No! Not the TOILET!!!

THE WRAP

There was so much more to report on from CES. Many of the new TVs and accessories will be featured in upcoming spring line shows, where I’ll take a closer look at each. You can also find news about specific model numbers and pricing at many other media outlets, along with each manufacturer’s specific Web sites.

If there was anything to take away from the show, it was that TVs were not the big news at CES this year. Instead, multi-function smart phones and connected media appliances generated all the buzz. We’re definitely in for a protracted battle between the “your TV should be the hub!” advocates and the “Connect outside the TV!” evangelists, not to mention the “go wireless!” and “use wired connections!” camps.

I tend to favor the “connect outside the TV” and “go wireless” arguments, although it is a tricky task to stream high-definition video in an uncompressed format between rooms in a house. (And no, the FCC taking away more UHF TV channels won’t help at all – there’s not enough spectrum space in the UHF band for 512 MHz channels!)

3D will continue to muddle along this year, as the economy slowly recovers and consumers sit on their hands. The confusing “glasses or no glasses” messages won’t help. Active-shutter 3D and passive 3d are clearly superior to autostereo 3D for viewing TV shows and movies, but you have to test-drive all three modes first to understand why. Look for the passive systems from LG, JVC, and VIZIO to pick up more market share as the year winds on and consumers realize they can use their freebie movie theater glasses at home.

LG's placing its bets on passive 3D TV.

Samsung's flexible OLED displays don't get bent out of shape.

NeTVs are here to stay and potentially a lot more popular than 3D. Sony’s Google TV approach may be too complicated for most consumers, who are likely to favor the simpler direct channel apps offered by everyone else. And if they can access Netflix, YouTube, and Hulu Plus, they may not need much else. Look for LG’s Internet converter box to be copied by other manufacturers so that older TVs can join in the fun.

It was nice to see a few OLED TV demos this year, but once again the technology just isn’t ready for prime time. Look for Samsung to show an OLED Galaxy tablet later this year, if for no other reason than to prove they can make one. But it will be a while before you can buy it. The rest of the tablet and smart phone crowd will stay with tried-and-true LCD technology for the time being.

Blu-ray disc and player prices will continue to plummet. I’ve predicted that major brands will stop making conventional DVD players altogether in 2011, moving to Blu-ray as their exclusive platform. While we didn’t see any BD players with internal hard drives like those sold in Japan, they’re not far off. Too many people are using Netflix streaming and would like to try a straight digital download for improved image quality. What better place to enable a DVR than in a BD multifunction media hub?

And get used to using your smart phone to do everything. Game console controls, TV remotes, autostereo displays, even diagnostic tools to use with connected major appliances – all of these smart phone applications were shown at CES.

So was a iPhone case with a built-in bottle opener, which might turn out to be one of the most useful smart phone “apps” of all…

No comment!
