Product Review: Samsung UN46C7000 3D LCD TV

If you attended CES back in January, you couldn’t escape 3D. It was everywhere in every booth, staring down from plasma and LCD TVs, projected from hanging screens, and dazzling on super-thin OLED monitors.

There is no question that TV manufacturers put some heavy bets on 2010 being the year of 3D. And most of the heavy betting came from Samsung, who originally announced 19 different models of LCD and plasma 3D sets at their press conference.

As things played out, public reception to 3D TV has been mixed. Numerous surveys have been taken that show consumers think 3D is certainly cool, but not many of them plan to buy a 3D TV this year. Is it too early in the technology curve? Is the lingering recession keeping wallets shut? It’s hard to say, but the fact is that 3D is coming along slowly – perhaps more slowly than manufacturers would like.

No, those cute lil' monsters do NOT come with the TV.

Samsung’s UN-46C7000 ($2,599 list) is one of the smallest 3D TVs available. For this review, I purchased Samsung’s BD-C6900 3D Blu-ray player for $249 at Amazon.com, as it was difficult to procure a press sample. (You can now buy this player for $214 at several different online stores.) Of course, right after it shipped, Samsung’s PR agency sent me the new BD-C6800 player. Figures!

OUT OF THE BOX

The UN46C7000 is ready to rock and roll. You’ll spend a few minutes assembling the support stand and trying to figure out how to attach it to the back of the incredibly-thin TV (something Samsung’s lab folks have had to deal with, too).  The finish around the bezel and on the stand is a shiny silvery color, which I find a bit distracting. But it goes to the old saying that “televisions are furniture,” I guess.

Samsung has provided plenty of input connections on this TV. There are four HDMI inputs, all of them version 1.4a compatible. Input #1 also supports connections to a personal computer, while Input #2 is the audio return channel (ARC) connection for an external AV receiver.

Believe it or not, THOSE are the analog video connections, along with the antenna input (far left).

There’s also a single analog component video (YPbPr) connection, a sign of the times. How much longer before this connection goes away altogether?  Of course, composite video connections just WON’T go away, and there’s one of those, too. Note that all of these analog connections do not use conventional RCA jacks – there’s no room for ‘em.

Instead, Samsung provides special breakout cables for component and composite video, along with analog video hookups. The actual plugs are stereo mini types. The same space/size problem applies to the Antenna input – Samsung provides an adapter to go from the standard threaded F-connector to a mini slide-on coaxial connector.

All of the HDMI connections support CEC, so when you turn on your Blu-ray player, the TV also powers up and switches to that input automatically. Want to feed digital audio from TV programs to your AV receiver? Samsung’s gotcha covered with a Toslink output jack, but you’ll need to come up with the cable. And as I just mentioned, HDMI input #2 will provide an audio return path to your receiver.

Four HDMI inputs are arrayed vertically along the left side of the rear panel.

MENUS AND ADJUSTMENTS

Samsung’s menus haven’t changed much over the years.  There are four image presets, labeled Dynamic, Standard, Natural, and Movie. Suffice it to say that you won’t want to run the TV for very long in Dynamic mode, as the pictures are extremely bright and over-enhanced. Standard, Natural, and Movie modes all work well for everyday viewing, but if you are into calibration, you’ll need to use Movie mode.

In addition to the Big 5 adjustments, you can also select from four different color temperature settings, five different aspect ratio settings, and a host of ‘green’ energy setting modes called Eco Solution. There are five different settings for screen brightness – including one that turns the image off, but leaves the sound on – and there’s also an ‘Eco Sensor’ that adjusts picture brightness based on ambient room lighting conditions.

If you think all of these settings play havoc with gamma, you are correct! And there are other image ‘enhancements’ that Samsung has included that will also result in some strange gamma curves, including three different black levels, three settings for dynamic contrast, and a shadow detail enhance/reduce adjustment. My advice is to leave them all off.

Samsung's backlit remote controls have gotten pretty snazzy in recent years.

Thanks to former home theater magazine editor Mike Wood, who know runs Samsung’s test lab in Los Angeles, we’re seeing more calibrator-friendly adjustments in the image menu. There are two Expert Patterns (grayscale and color) for basic brightness, contrast, saturation, and hue calibrations. You can also select red, green, and blue-only modes, as well as Auto, Native, and Custom color spaces. The Custom mode lets you define your own x,y coordinates for primaries.

For color temperature calibration, Samsung provides two-point and ten-point RGB gain and offset adjustments. The theory is to do most of the calibration in two-point mode, then go back through a multi-step grayscale in ten-point mode for fine-tuning. (It almost worked for me, with one hiccup.)

Other adjustments include Flesh Tone enhance (leave it off), xvYCC mode (leave it off as well, no one currently supports extended color in packaged content), and the usual edge enhancement (peaking) stuff. (Remember, HDTV doesn’t need edge enhancement – it’s high-definition, savvy?)

There are a couple of noise filters that have some effect on image quality. The MPEG noise filter attempts to use low-pass filtering to get rid of mosquito noise and macroblock (excessive compression) artifacts. Be warned that low-pass filtering softens high-frequency image detail, so go easy on these controls. There’s only so much you can do to turn chicken turds into chicken salad, as my old college film professor used to say.

We’ll wrap things up with a discussion of Auto Motion Plus. This feature, which is pretty much de rigueur on all new LCD TVs, corrects for 24-frame judder by pulling the frame rate up to multiples of 60 Hz. In the case of the UN46C7000, the corrected frame rate is supposedly 240 Hz. What this actually does to images is to make filmed content look like it is live, or shot at video rates.

Whether this is esthetically a good thing to do is a matter of debate. The result is a very smooth presentation, free of flicker and judder, but it just doesn’t look the same as a movie. The motivation behind Auto Motion Plus (and every other TV manufacturers implementation of it) is to get rid of motion blur and smearing, something that all LCD TVs suffer from to various degrees. Try it – you may like it, you may hate it.

3D MENUS

Thought I’d forgotten about these, eh? Samsung 3D TVs are quite smart enough to recognize when 3D content is streaming through their inputs, unless it is encoded in the HDMI v1.4a frame packing format. This format, which delivers movies in the 1920x1080p @24 Hz format, is so unique that if you start playing a 3D Blu-ray disc, the UN46C7000 will automatically switch into 3D mode – no further adjustments required.

The two frame-compatible 3D formats (1080i side-by-side and 720p top+bottom) require some help from you to be shown correctly. Once you’ve established that you are indeed seeing the unprocessed 720p or 1080i 3D program from your content provider, go into the UN46C7000’s 3D menu and turn 3D mode ON.

Your will then be presented with a menu of 3D frame compatible formats to choose from, including side by side (1080i), top & bottom (720p), and several esoteric formats like line by line, vertical stripe, checkerboard (also known as quincunx), and frequency. That last format alternates full-frame left and right images in a similar manner to active shutter 3D, but at slower frame rates.

Aside from frame packing and side-by-side/top & bottom, you are most likely to run into the checkerboard format when playing back 3D games and other non-standard media. The other formats are not widely used, but you may come across them with Internet-delivered or broadcast content in the future.

Samsung also has a 2D to 3D conversion algorithm built-in to all of their 3D TVs. Try it – the effect is noticeable at times, but still doesn’t look quite right to me. My advice is not to try and add synthetic 3D effects to everyday TV shows and movies, but stick with content that has been specifically formatted for 3D. (Readers who saw Clash of the Titans in 3D know what I’m talking about.

ON THE TEST BENCH

Given all of the image enhancement adjustments present in this TV – and the auto-dimming circuitry that boosts black levels – it is difficult to get an accurate read on gamma performance and contrast. Nevertheless, I did run a basic set of test patterns and came up with some mostly-believable numbers, using 1920x1080p test patterns from an AccuPel HDG4000 generator and ColorFacts 7.5 calibration software.

After my best calibration, I measured brightness in Movie mode at 110 nits  (32 foot-Lamberts). That number ranged as high as 400 nits in Dynamic mode (tanning lamp mode), 201 nits in Standard mode, and 210 nits in Natural mode. ANSI (average) contrast was clocked at a respectable 621:1, with peak contrast from  checkerboard pattern at 722:1.

Because of the auto dimming feature with low-level content, peak contrast can reach amazingly high levels. In Movie mode, a sequential white/black measurement reached 20,567:1, and soared to 400,000:1 in Dynamic mode. (Not that your eye can actually see that level of contrast.)

It's kinda wobbly-looking, but this 2.44 gamma was the best I could pull from the TV.

White balance uniformity was respectable for an LCD TV. Maximum color temperature shift across a full white screen was 388 degrees Kelvin, while maximum color shift across a nine-step grayscale was 287 degrees Kelvin. During one of my ten-point calibrations, the gray pattern at 30 IRE shifted noticeably blue-green, resulting in a bump up to 7260K. I’m not sure why it happened – going back and recalibrating in two-point mode fixed the problem.

That's a pretty impressive grayscale track!

And here's the reason why - look at the RGB levels, which vary little from black to 100 IRE.

I mentioned the screwy gamma curve performance earlier. You’ll tear your hair out trying to get a consistent gamma on the UN46C7000, so you’ll just have to settle for your ‘best shot.’ That’s what I did with an effective but wobbly 2.44 gamma in what I called my ‘best’ calibration out of ten. Not satisfied, I came back and tried it again with a ‘final’ calibration and didn’t see a significant difference.

But both curves were a lot cleaner than what I started with, which was S-curve gamma response in almost every picture mode. The culprit? That doggone auto-dimming circuit that forces deep blacks when the on-screen content has low luminance levels. Needless to say, you don’t want to be using a TV like this as a reference-grade monitor.

The UN46C7000 has a surprisingly accurate color gamut when compared to the BT.709 standard color space for HDTV. It just comes up a bit short on red and is oversaturated with green and blue. You can fix this to some extent using the Custom color space control, but red, yellow, and green are then undersaturated as a result. Can win ‘em all…

 

Here's the UN46C7000's factory color gamut...

...and here's the corrected color gamut, albeit light on green, yellow, and red.

IMAGE QUALITY

Because this TV is primarily marketed for 3D use, I decided to make most of my image quality judgments based on 3D content.  Of course, that didn’t leave me a lot of options for programming as I could only choose from 3D sports on ESPN, or the sole 3D Blu-ray disc in my possession – Monsters Vs. Aliens.

My thoughts on 3D football have already been published and can be found here. As for image quality, I found myself switching to Natural or Standard mode to pick up the additional brightness I was losing through Samsung’s active shutter glasses – about 50%, according to the basic physics of light. Movie mode was not bright enough for viewing 3D unless I had all ambient room lighting dimmed and there was little or no outside light.

Of course, switching out of Movie mode when watching a 3D movie tosses all of your calibration efforts out the window. How’s that for a conundrum? Your best image quality isn’t bright enough for watching 3D movies. (I knew there was a catch to this 3D thing…)

Switching in and out of Auto Motion mode fixed up quite a few motion blur problems observed in ESPN’s 3D telecast of the Ohio State – Miami football game, which I also elected to watch in Standard mode so I could throw away 100 of those 200 nits, yet still have acceptable screen brightness. I didn’t have a chance to use it to watch conventional movies.

This is the 21st-century version of the old Indian chief test pattern.

The 3D experience using frame compatible formats isn’t quite the same as watching frame-packed 3D from a Blu-ray. The latter format has more detail, more contrast punch, and  is just a lot more satisfying to watch. Because the two frame-compatible formats are half-resolution, image detail on long and medium shots didn’t quite measure up to ‘straight’ HD as seen from ESPN’s 2D telecast of the same game on my adjacent Panasonic 42-inch 1080p plasma.

Monsters in 3D was a very enjoyable experience. I did observe a slight amount of crosstalk through Samsung’s glasses, mostly when bright or near-white objects were present in the frame, such as Dr. Cockroach’s white lab coat, or white text on signs. Auto Motion was disabled and I didn’t see much in the way of objectionable judder, although animated movies tend to be ‘cleaner’ in this regard than live action films.

In general, it’s tough to make critical observations about 3D image quality because the images are so much dimmer. And it is discouraging that the best calibrated mode was too dark for my liking, resulting in dull colors and lower contrast. But given the screwy gamma response I saw in all modes, maybe I should have just sat back and enjoyed whatever appeared on the screen.

2D was a different story. In Movie mode, images had saturated, accurate color, plenty of contrast pop, and more than enough brightness for everyday viewing. Once ambient room light levels get to a certain point, you don’t really see any elevated black level issues. But you will see a flattening of contrast and a drop in brightness as you move off the center axis, something all LCD TVs have to contend with.

CONCLUSION

Samsung’s UN46C7000 is representative of current 3D LCD TV technology, using edge LED backlighting, auto dimming, and a super-thin design.

In terms of 2D performance, it is a strong performer despite those issues relating to gamma performance. In fact, it’s one of the best ultra-thin LCD sets I’ve examined in recent years, even though the patterned vertical alignment (PVA) liquid crystal layer still has some problems with color shifts when viewed off-axis.But it is bright, the colors pop, and images are detailed and crisp, especially after you go through and disable all of the so-called enhancements. And as you can see from the charts, once you calibrate it, it stays tight when tracking a specific color temperature.

As a 3D set, it does a workmanlike job, but could use more help with critical adjustments at higher brightness levels. You can’t calibrate anything in any mode other than Movie, so your only option is to crank up the brightness and try to recapture some of the light lost in Samsung’s active shutter glasses. That may screw up the TV’s gamma response, through.

SAMSUNG BD-C6900/BD-C6800: Samsung’s 3D Blu-ray players are very easy to set up. Plug them in, power up, and the CEC sensor will automatically turn on the TV and switch to that input. Both players are WiFi enabled, and will prompt you for a connection to your home network using manually-configured IP setup or the default automatic (DHCP) configuration. If you don ‘t know much about TCP/IP configurations and addresses, use the automatic mode to set it and forget it.

Both players can stream content from Netflix and also from your home media servers, so you can watch video clips, look at digital photos, and listen to MP3 music files and Internet radio from Pandora. The players will automatically configure themselves to the 1080p/24 frame-packing format when a 3D Blu-ray disc is loaded, and the default output resolution is 1080p for Samsung LCD and plasma TVs.

Current Web prices on this TV range from $1,370 to $2,200 as of November 10, 2010.

Power consumption tests – Over an 8-hour period, the UN46C7000 consumed an average of 106.4 watts while in Movie mode with full-screen content.

The 3D Fire Sales have Begun

PriceSCAN has just released its latest 3D Blu-ray Player Index, and it’s a doozy.

The 3D BD Player Index is a composite of all models currently at retail, and the average price for those models has dropped by 26% in six months, with a 10.6% drop in just the past week.

PriceSCAN listed Sony’s BDP-S570 as a good example of aggressive discounting. This player, which required a firmware upgrade to support 3D playback, has fallen from a retail price of $250 to $170 since late February.

From my own experience, I was able to score Samsung’s BD-C6900 3D BD player for just $244 plus shipping from Amazon in early September. Its original list price was closer to $400 when unveiled shortly after CES.

These rapid drops in retail prices reflect the low level of enthusiasm for 3D TV that has been evidenced to date. In an earlier post, I referenced an NPD Group study that showed only 11% of respondents in a recent poll had any plans to buy a 3D TV in the near future, citing concerns about technology, cost issues, the lack of content, and the need to wear expensive, proprietary glasses.

Can prices on BD players and TVs drop low enough to overcome the other objections? Probably not, as the lack of content is still a big problem. There needs to be bucketloads of 3D content available to drive sales, and right now, we’re talking about glassfuls.

If you are thinking about taking the dive into 3D, you’d be best off sitting on your hands for a few more weeks. I have a feeling we’re going to see even deeper discounts on BD players and TVs, probably on the order of 30 – 40% by the time January rolls around.

Think I’m nuts? I just Googled retail prices for the BD-C6900, and it’s now down to $214 (plus shipping) at Amazon, Tiger Direct, PC Richard, Vann’s, and ABT.  (Buyer’s remorse alert – I bought one too soon!!)

Memo to 3D TV manufacturers: First, you build the highway. Then, you build the cars!

The latest PR blurb from CEA headquarters shows that, in a survey taken of 250 sales associates in retail stores, consumer enthusiasm for 3D is strong, with 50% of customers reporting a positive response to 3D technologies, and only 2% reporting a negative response.

That’s not necessarily good news. Do the math, and you’ll see that 47% of customers had no feelings about 3D TV one way or the other, or didn’t respond. (Or were distracted by their teenagers repeatedly begging Mom and Dad for an iPhone or iPod Touch.)

The CEA report does go on to say that “…While nearly 70 percent of sales associates feel well trained to answer questions about 3D, there is still consumer confusion. According to the retail associates interviewed, roughly half of consumers had some confusion about the technology.” That pretty much covers the 47% who didn’t respond positively or negatively.

And now for the devil in the details! “…For most retail associates, 3D content is pivotal. Nearly 80 percent of the associates interviewed believe sales of 3D technologies will not be strong until more 3D content is available.  Moreover, some of the most frequently asked questions by consumers revolved around the availability of 3D content. “

World Cup in 3D…Been there, done that. What else ya got?

There’s the rub. 3D may look great in the store, but how much 3D World Cup coverage can you watch before nodding off? (Hey, did you catch Paraguay and Japan fighting to a 0-0 tie?) And there are only a couple of 3D Blu-ray discs out there that haven’t been exclusively linked up to a 3D TV bundle promotion.

DirecTV is taking some steps to solve the problem today, announcing the launch of its 24-hour 3D channel in conjunction with Panasonic at a New York City press event. That’s good news for DirecTV customers, but it’s not much help to cable or Dish Network subscribers who are currently limited to ESPN 3D.

If this seems like déjà vu all over again (apologies to Yogi Berra), it is. Remember the start of the digital TV transition in 1998, when exactly two DTV stations went on the air? (For trivia buffs, they were WRAL (CBS) in Raleigh, NC, and WFAA (ABC) in Dallas-Ft. Worth, TX.)

Set-top boxes cost about two grand. You needed component inputs on your TV that could accept the 1080i signal from the box (good luck with the 720p outputs), plus an antenna, and maybe a preamp, and a bunch of coax, and a compass to tell you where to aim the antenna.

Oh, and yes – you needed HDTV content. But there was very little of it back then, aside from some CBS prime-time programs and the ABC Saturday Night Movie. It wasn’t until four years later (2002) before most of the TV networks were carrying a majority of their evening programs and sports coverage in HD. Can 3D TV manufacturers afford to wait that long?

It’s encouraging that 70% of the sales associates interviewed by CEA felt competent enough to answer questions about 3D. But that’s not the problem, based on my experience last Sunday at Best Buy. Only two out of four 3D TV demos in the store were actually working, and one was located in the worst possible spot for a demo. The other had only one pair of working 3D glasses. How do you answer questions about 3D, when customers can’t even see a demonstration of it?

This is where a company like Sony has a leg up with their Sony Style company stores. They can ensure (and they’d better!) that potential customers get the best possible 3D demo, with a large screen LCD TV and comfortable seats positioned at the correct viewing distance. And they can put together a nice mix of live 3D (Sony is a World Cup sponsor) and clips from Sony Pictures 3D movies (think Cloudy with a Chance of Meatballs).

Samsung’s ‘experience’ store in the Time-Warner Center in New York City is also an excellent place to demo 3D. (Hmmm. Maybe Samsung should be thinking about opening their own company stores!) Alas, Panasonic has no such showcase and is at the mercy of Best Buy and Sears. And Mitsubishi (who has some of the most compelling 3D TV value propositions right now) has no 3D showcases at all. (Too bad they can’t just truck their June NYC line show around the country!)

Now, THIS is how ALL 3D demos should look. (Dream on…)

But all the demos in the world won’t do any good if there is nothing to watch in 3D. And for the vast majority of potential 3D TV customers, there just isn’t enough to watch in 3D right now, so the credit cards and checkbooks are staying in pockets and purses.

Hopefully, that problem will sort itself out by year’s end, when we should see a flurry of 3D BD releases, more coverage of sporting events, the launch of Discovery’s 3D channel, and maybe even some 3D streaming from Netflix. (That last possibility assumes Netflix can get over some significant technical hurdles, such as bandwidth.)

Hint to TV manufacturers, and to Fox Sports: S-U-P-E-R B-O-W-L I-N 3-D. (Think that was subtle enough?)

So, we’re back to 1998. Grab some shovels and picks, and let’s get started on those highways! (Maybe there are still some stimulus funds available?)

3D TVs: Not Selling like Hotcakes?

Thinking about buying a 3D TV? You might be wise to sit on your hands for a while longer, because you’ll save a few hundred dollars and get more equipment at the checkout line to show for your patience.

Sunday’s Best Buy insert showed a Panasonic 3D TV package that includes the TC-P50VT20 3D plasma TV (comes with one pair of glasses, PLUS an extra two pairs of active shutter glasses, PLUS Geek Squad delivery and setup, all for $2249.96. That supposedly reflects a $700 savings over full list price. (The extra two pairs of glasses are valued at $300).

A few months ago, Panasonic announced a 3D bundle of the TC-P50VT20, one pair of glasses, and their BDT-300 3D Blu-ray player ($399.00) for $2,899, exclusively at Best Buy. That package likely ran out of gas quickly because there are only a handful of 3D Blu-ray discs available to watch right now.

So Best Buy’s new deal shifts focus to ESPN’s 3D coverage of the World Cup soccer matches, which started on June 11. All fine and dandy, but the ‘catch’ is that some cable TV customers will have to upgrade to newer Samsung, Pace, Motorola, and Cisco set-top boxes to receive the ESPN 3D channel – it can’t be done on older set-tops. (And good luck finding out exactly where and if ESPN 3D pops up in your service area!) UPDATE: Comcast is carrying the ESPN 3D signal in the 1080i side-by-side format, encoded as MPEG2 @ 18 Mb/s.

Samsung and Best Buy may have put together an even better deal. For $2769, you can get a UN55C7000 55-inch 240Hz LCD TV (LED backlit, of course) PLUS a BD-C6900 Blu-ray player, PLUS a 3D starter kit (two pairs of AS glasses and a copy of Monsters vs. Aliens in 3D), PLUS the Geek Squad delivery and setup as before. Don’t need a 55-inch screen? Substitute a UN40C7000 40-inch LCD 3D TV, and the price drops to $1799.

The 3D ‘kit’ is all yours for about $2800 bucks.

‘New kid on the block’ HH Gregg (at least, new in eastern Pennsylvania) has the same deal on the 55-inch set, or you can go with a 46-inch model for $2139. (They don’t mention anything about installation and setup, though.) Sixth Avenue Electronics also has the 55-inch and 46-inch packages, and will do free delivery and installation on both.

The Sears Sunday flier states that you can get the BD-C6900 BD player and the 3D starter kit free with the purchase of any Samsung 3D TV, which might be the best deal of all. They’ve priced the 46-inch LN46C750 3D TV (CCFL backlight) at $1529, while Samsung’s PN-50C7000 3D plasma TV is tagged at $1799.

Imagine that. We’re barely three months from all those big 3D product launches in New York, and prices have already started dropping like a stone. To make matters even more interesting, XpanD announced a few months ago at the NAB show that they plan to introduce universal ‘learning’ active shutter glasses to the marketplace later this year, which will directly impact the sales of proprietary AS glasses.

These bundled prices make you wonder about the real value of the glasses and Blu-ray players. In a business where margins are very tight, accessories such as glasses, cables, and even installation services are very important to the bottom line. Both the Panasonic and Samsung BD players list for $400, but my guess is that neither is selling very well right now: Hence, Panasonic’s decision to de-emphasize the player and Samsung’s ploy to throw theirs in as an extra to drive TV sales.

What will be telling is how much this year’s World Cup 3D coverage drives TV sales. You may recall that the World Cup did little or nothing to stimulate sales of HDTVs four years ago because Asian TV manufacturers overlooked an obvious fact: World Cup fanatics in Europe prefer to watch matches in pubs and taverns with their pals – not at home.

While ESPN is to be commended for making a substantial effort and investment to produce 3D coverage, it’s unfortunate that one of the least-appealing sports to Americans (historically speaking) is the focus of this coverage and not something like baseball, or basketball (NBA Finals), or even tennis.

What happens after July 11, when the Cup tournament concludes? How much 3D coverage will be available to drive TV sales throughout the summer?

Apparently not very much, based on the announcements made to date. And that means we’re likely to see even bigger discounts on 3D TV packages by September.

(By the way, none of the package deals I mentioned includes an HDMI cable. Hey, retailers have to make a buck someplace!)

NAB 2010: A Show in Transition

Some of the big questions facing attendees as their flights landed in Las Vegas were these: Can NAB survive? Will it evolve into something different? Is it even that important to attend NAB anymore?

The answer to all three questions is “yes.” Even though attendance was still down from 2008 (NAB claimed 83,000 ‘officially;’ my guesstimate was more like 55,000 to 60,000), there were plenty of companies in attendance with lots of cool products to check out.

That said, the show is undergoing a rapid transformation away from a traditional ‘broadcasting’ show to a mix of InfoComm and CES – hot new products for professionals. Of course, 3D was all over the place. But so was networked video, which dominated the upper and lower South Hall exhibit areas.

Booths were smaller this year, and that’s not going to change any time soon…not when the typical booth is showing products that have price tags in the hundreds and low thousands. Contrast that with NAB shows 15 years ago, when most of the price tags had three and four zeros in them!

You know attendance was off when this was one of the largest booths in the Central Hall!

On the other hand, the alternative wasn’t too attractive…

The smaller booths and lower number of exhibitors resulted in wider aisles and less traffic – a plus. But it also resulted in NAB placing the main registration area smack in the middle of the Central Hall, something I’ve never seen before.  And there was plenty of wide-open space at the end of that hall, as well in the North and South Halls.

Can NAB be staged in three halls? Absolutely! And can you see everything you need to see in three days? Try two days. (Thursday has become ‘exhibitor bonding day,’ to quote a fellow editor.) I could have covered my beat in two days if necessary.

THE TRENDS

Not surprisingly, 3D was a big topic this year, although not to the same extent as it was at CES. The SMPTE/ETC/EBU Digital Cinema Summit focused entirely on 3D for both days, and I was fortunate enough to deliver one of the papers to a jammed room of 500+ attendees.

Sony, Panasonic, JVC, Canon, Grass Valley, AVID, Doremi, Harris, Evertz, and Ross Video were just some of the companies showing 3D products in Vegas. Those products ranged from 3D monitors and cameras to 3D workflow (acquisition, editing, post, effects, and playout) software and hardware.

Sony’s LM4251TD 42-inch LCD monitor uses micropolarizers for passive 3D viewing.

Other specialized 3D brands were in attendance, too. TD Vision, Miracube, Mistika, and HDlogix had nice exhibits in the South Hall, down the street from Grass Valley. Smaller companies like Cine-tal occupied the 3D Pavilion nearby, while Motorola and Ericsson showcased 3D transport and format recognition products upstairs.

Although the consumer TV market is seeing a big push towards active-shutter 3D TVs and monitors, the emphasis at NAB was on passive 3D viewing (cheaper glasses, more expensive displays). JVC, Hyundai, and LG all manufacture them, and there were plenty of folks standing around with RealD X-pol eyewear watching the demos.

The projector guys were on top of things, too. projectiondesign showed a stacked pair of 3-chip 1080p lightboxes in the Mistika booth, using linear polarized glasses. HDI showed a 100-inch, 1080p LCoS rear-projection TV in the HDlogix booth, also using X-pol glasses. Christie also had suitable 3D projection systems out for inspection.

There were also some demos that left me scratching my head, such as Canon’s dual-projection X-pol 3D demo, using a pair of REALiS WUXGA (1920×1200) LCoS projectors. While it worked well, it requires two separate projectors and outboard 3D filter holders – too klunky! (A Canon rep told me that was because of the 60 Hz frame rate limitation on the internal video processor.)

Well, it IS 3D, but I doubt Canon will sell very many of these rigs…

Broadband video and IPTV were also big this year. This market for MPEG-4 AVC over Ethernet, fiber, or private data networks is exploding, and encoder companies such as Adtec, Vbrick, Harmonic, Ericsson, Harris, Motorola, and Digital Rapids were showing a full range of compatible products.

Sezmi also occupied a booth at the show. This company has a unique selling proposition – a set-top box that receives both terrestrial (read: free) digital TV and selected cable channels carried on secondary terrestrial channels. It also accesses a video-on-demand server through broadband connections (SDTV only) and has a customizable program guide for each user.

While not technically broadband, the nascent MH broadcast format was in abundance at NAB. MH uses MPEG-4 AVC coding in multiple streams with IP headers to send low-resolution video to handheld receivers, such as mobile phones and combo PDA/receiver products. MH is catching on in popularity with broadcasters, who see it as a more sensible alternative to simple multicasting of secondary channels that very few people may be watching.

ATSC MH on an iPhone? Brilliant! (There’s an app for everything!)

MY PICKS

After three days of walking around, I came up with a list of “finds” that I’ll share here. These are all products that represented clever thinking, breakthrough technology, and/or new price points. Some were easy to spot; others required quite a bit of digging. But they all made the trip to Lost Wages worth it (and that’s saying a lot, considering how airlines jam you in like sardines these days!).

TV Logic: This manufacturer of LCD broadcast monitor showed the world’s first active-matrix OLED broadcast monitor (unless you think Sony’s press announcement hit first, which it didn’t.) The LM-150 ($6,200) uses a LG Display 15-inch OLED panel with 1366×768 pixel resolution and come equipped with all the expected niceties including markers, crop marks, caption displays, over/underscan, and HD/SDI, HDMI, and analog video jacks. There’s also a 3D version in the works (TDM-150) that will sell for about $7,700.

This was the coolest product at the show. But will it REALLY last 30,000 hours?

Ericsson: In addition to a host of MPEG-4 and IPTV encoders, the ‘big E’ also showcased an innovative, iPad-like LCD touchscreen remote control/video viewer. Dubbed the IPTV remote, this product can dial up video from broadband, cable, satellite, and even your home network. Not only that, it can monitor weather sensors and your home security system. (Sound much like a Crestron product?) The IPTV remote will not be offered for sale at retail. Rather, it’s intended to be a content provider offering.

Christie: Have you seen their MicroTiles yet on the Colbert Report? These innovative ‘mini’ DLP projection cubes use LED light engines to power 800×600 DMDs (the actual working resolution is 720×540) and measure about 12” x 16.” They can be configured in just about any format you wish, including floor and ceiling projection, and up to 1024 can be driven at one time. The LED light source is specified to last over 60,000 hours. Think of LED-powered LEGOÔ blocks, and you’ve got the concept.

And YOU thought iPads were all the rage…

SmallHD: It wasn’t easy finding these guys behind the Sony booth, but they’d come up with a focus assist monitor for video and still cameras that they claim is the world’s smallest HD video monitor. The actual size is about 5.6 inches and the glass is WXGA (1280×800) LCD. It comes in two flavors – one for digital SLRs ($899) and one with SDI input ($1199). The monitors are an inch thick, weigh 10 ounces, and mount to hot shoes.

Z3 Technology: I found this booth on my last pass through the South Hall, and it was worth the stop. They showed the Z3-MVE-01 MPEG encoder, a compact box that codes HD up to 1920×1080 resolution using H.64 High Profile (up to 30Hz), with Ethernet and ASI outputs. Input compatibility includes composite, component, HDMI, DVI, and HD-SDI video…all for $5,000.

JVC’s 46-inch X-pol monitor always drew a crowd.

Adtec: I didn’t expect to see an HDMI-to-QAM modulator at the show, but that’s exactly what Adtec pulled out for me. The HDMI2QAM is a dual-channel design that encodes anything from the HDMI inputs (yes, they are HDCP-compliant) to a pair of quadrature amplitude modulation (QAM) channels, using MPEG-2 encoding. The modulation format is selectable between 64-QAM (SD), 128-QAM (not widely use), and 256-QAM (HD). Bit rates are constant and optimized for each mode (i.e. 38.8 Mb/s for each HD channel).

 

Cydle: This new start-up demonstrated an app for iPods and iPhones that allows viewing of ATSC MH (A/153) video. Along with it comes the i30,  a battery-powered docking station with built-in antenna (UHF). This means that your ‘i-whatever’ has two batteries to draw from, so if you run low on talk power, simply switch to the i30 battery. Both can charge simultaneously. Cool!

Sezmi’s personal program guide rivals TiVo for user-friendliness.

Panasonic: I’ve seen it before at CES, but it now has a model number. The company’s first production camcorder now goes by the moniker AG-3DA1 and is yours for the low, low price of just $21,000. (Well, all things are relative, I guess.) The camera weighs about 6 and a half pounds and uses a pair of 2.l07 MP sensors (full 1920×1080) to record 1080i and 720p HD content to SD memory cards. Convergence and horizontal and vertical displacement are fully adjustable.

Panasonic gets another mention for the AG-AF100, which they claim is the world’s first Micro 4/3-inch (1.33:1) HD camcorder. That’s a big deal because the 4/3” format matches the coverage area of 35mm film frames…which means you can use standard 35mm film camera lenses to get effects like shallow focus, soft focus, and vignettes. The camera records to SD/SDHC/SDXC memory cards using the AVCHD format and supports 1080i/p and 720p formats, including 23.98/24/25 Hz.

Sony gets extra credit for announcing the world’s second (or first) AM-OLED professional video monitor. The PVM-750 ($3,850) is a bit smaller than TV Logic’s offering at 7.4 inches (16:9), and is not quite full HD resolution at 960×540 pixels. (Not that you’d notice on such  small screen!)  The PVM-750 has 3G HD-SDI, HDMI, and composite video inputs, the full range of adjustments from tally and markers to blue screen mode and AC/battery power operation. No word on lifespan of the display, but Sony uses small molecule (SM) OLED technology, as does LG Display.

LP Technologies rounds out my list with one of those ‘too good to be true’ products: An LCD-based 9 kHz to 3 GHz spectrum analyzer with USB 2.0 interface, built-in preamp, and Ethernet connectivity for remote monitoring. Sorry, no internal battery pack!) The USB hook-up can be used to save data in the Excel format, while the internal memory can tore 900 different waveforms. The display is a 6.4” 640×480 (VGA) LCD type. And the cost? Just $4,500…

Stick one of these on a Canon 5D MK II, and you can shoot an entire episode of ‘House!’ (No kidding!)
