CES 2010: Is 480Hz the new 240Hz?

At CES, at least two companies, LG and Toshiba, are touting new LCD TV models with "480Hz" technology, seemingly upping the ante on efforts to reduce or eliminate motion blur during fast-moving scenes. 

Similar to the way they've approached 240Hz technology, both these companies are combining actual increases in the TV's frame rate (motion estimation-motion compensation) with a scanning (flashing) backlight to create a 480Hz effect. The key question, of course, is whether 480Hz offers a noticeable improvement in performance over 240Hz technology—and whether it will be worth buying a high-priced TV to get it.

We'll certainly test this new feature when these TVs are released, but remember that the improvements we've seen with 240Hz technology are most evident on our test patterns, not standard TV programs or movies. It's even possible that these technologies might introduce some artifacts we find more objectionable than slight motion blur.

Stay tuned for more detailed reports on 480Hz and some of the other new technologies we're seeing here at CES.

CES 2010: Motorola flips over an Android phone

Motorola yesterday demoed the Android-powered (initially version 1.5, with a later upgrade to 2.1) Backflip phone with an interesting design: its QWERTY keyboard is on the back and flips around when you need it. Grips on the underside of the keyboard allow you to place the phone on a tabletop so you can type on it like a laptop computer.

The Backflip has a 3.1-in touch screen that does something else cool: You can interact with it via a trackpad located behind the screen. The idea is that you can select objects and perform other on-screen tasks without your fingers blocking your view. Not sure how practical it is, but it does work.

The phone, which seems to be a good ½-inch thick when closed, also has a 5-megapixel camera, Wi-Fi, a full Web browser, and GPS navigation. Its Motoblur feature backs up all of your home screen customizations, e-mail, and social network messages in case your phone breaks, or is lost or stolen. And if your phone is lost or stolen, Motoblur uses GPS to help you find it, or lets you remotely wipe all of your personal information to protect you from identity theft.

The Backflip will be available in Q1 this year. Though no carrier was announced, the spec sheet shows it supports AT&T 3G data network.

CES 2010: 3D TV is everywhere, but prices are still MIA

With most major brands announcing 3D TVs, we're getting a clearer idea of how the various companies will be integrating 3D into their TV lines. But what still remains to be seen is how much of a premium 3D TVs will command over more traditional sets.

Panasonic, which has been promoting 3D for more than a year, expects to
be among the first to actually ship a 3D TV when its
VT25-series “Full HD 3D” models arrive this spring. The four plasma
sets, in 50-, 54-, 58-, and 65-inch screen sizes, come with one pair of
active shutter-style 3D glasses. One of the company's guest speakers
was Jon Landau, producer of the 3D movie Avatar, which partnered with
Panasonic last year to promote both the movie and 3D technology.

Sony hit CES with a splashy press conference featuring a live performance by Sony Music artist Taylor Swift and a 3D demo for those lucky enough to be in the front rows. The company said it will launch three series of LED-backlit 3D HDTVs this summer, one of which—the flagship LX900 series—comes with two pairs of active-shutter glasses and the transmitter required for viewing 3D content on the TV. Two other “3D-ready” series (HX900 and HX800) will be similarly featured, except you’ll have to buy the glasses and transmitter separately. Screen sizes will range from 40 to 60 inches.

Samsung said half its LED LCD TV introductions in 2010 will be 3D models, many using a new “inspired by nature” design scheme. Heading the lineup are what could be the best-looking TVs I’ve seen so far, the ultra-slim 9000 Series. These sets achieve their svelte profiles by housing the TV’s electronics circuitry inside the stand. They come with a unique touch-screen Wi-Fi remote that doubles as a second display, so you can watch a TV program on the remote while a Blu-ray movie is playing on the TV. Samsung's other 3D-enabled models are 8000 and 7000 series LED LCD sets, plus a 3D-ready 7000 plasma series. Samsung said its 3D processor can convert standard 2D images to 3D on the fly.

Toshiba was at CES touting its new “Cell TV Series," a line of ultra-premium models that use the powerful Cell processor it helped develop originally for the PlayStation 3 video game console. ZX900-series sets, which have a two-piece design that includes a separate settop box with an integrated Blu-ray player and 1-terabyte hard drive, use the Cell processor to power its 3D engine, convert 2D content to 3D on the fly, and upconvert standard-def content for 1080p output. These sets have lots of bells and whistles, including a Kira2 LED panel with 512 zones that can be separately dimmed, wireless networking and Wireless HDMI, and video phone capability. Cell TV XV900-series models will be available in 55- and 65-inch screen sizes, though no firm shipment dates were announced.

LG Electronics unveiled a new family of Infinia-brand LCD TVs with LED backlights, including the LE9500 sets, which will be the company’s first 3D-ready models in the US. These ultra-slim sets, less than an inch deep, will be available in 47- and 55-inch screen sizes. They come with a new “Magic Wand” remote that can respond to gestures, much like Nintendo’s Wii video game remotes.

Although Sharp’s main TV focus was its “Quad Pixel” technology, which expands the color gamut on some Aquos sets by adding a fourth primary color—yellow—to the traditional red, green, and blue, it does have a 3D prototype at the show. However, there was little information about when it will ship its first model.

We'll be filing more reports on the new TV lineups, which include features such as wireless HDMI, increased access to online content such as streaming movies, 480Hz anti-blurring technologies, and LED backlights with more zones that can be locally dimmed, later in the week, so keep checking back with us for CES updates.

CES 2010: Opening Day—wireless woes plague reporters

Though the Consumer Electronics Show officially opens today, the Consumer Reports team has already posted plenty of news. There was the Google Nexus One smart phone announcement; QuadPixel technology from Sharp, which promises HDTVs that can display trillions of colors; electronic book reader or e-reader developments; and a new Lenovo smart phone destined for China.

This year, our coverage will include more video—that is, if the wireless connections hold out. (See my first video at right!) As in previous years, legions of media folks, bloggers, Twitter addicts, iPhone users, and Facebook fanatics seem to have overwhelmed some wireless networks and areas where free Wi-Fi is available. 

Co-workers here with personal iPhones have had only sporadic connections with AT&T's 3G network. In some cases, it took hours for text messages to get through to their cell phones. Interestingly, I've had no such slow-downs on Sprint's 3G network, though it's one of the lower-rated carriers in our recent Ratings of cellular service providers (available to subscribers).

My only complaint: The Samsung Moment, one of our recommended smart phones and powered by Android 1.5, doesn't have the battery life to keep up with my wireless connection needs, giving out in much less than the five-plus hours we achieved in our tests. These wireless woes have me wishing that I had one of Sprint's new 4G modems, which are supposedly available here in Las Vegas (one of Sprint's trial cities).

Check back soon for more news about e-books, our perspective on the keynote address made by Microsoft's Steve Ballmer, and some more video on YouTube.

CES 2010: Samsung NX10 compact camera breaks new ground

It's been nearly a year since Samsung introduced its concept of a new kind of digital camera, a compact with the power of a digital SLR, that appeared to go head-to-head with the SLR-like Micro Four-thirds models introduced by Panasonic and Olympus.

Now, that concept has a name, and the specs to go with it: At CES, Samsung has announced the 14.6 megapixel NX10, a new compact that accepts interchangeable lenses and is said to be small and light, just like a Micro Four-thirds camera.

The most important difference between the NX10 and the Panasonic and Olympus models is that the Samsung camera's sensor is based on an APS-C size sensor. Samsung's sensor is larger than the Four-thirds sensors used in Panasonic and Olympus cameras, which may mean that it will handle low-light situations better, although a larger sensor is only one of many factors in improving low-light performance.

Other important specs include:

  • A large 3-inch AMOLED (Active-matrix organic light-emitting diode) screen, which Samsung claims will be brighter and have lower power consumption than current LCDs.
  • HD video capability at 720p HD using the MPEG4 (H.264) codec.
  • A sharp electronic viewfinder.
  • A built-in popup flash.
  • The first three lenses for this system are the 18-55mm OIS, 50-200mm OIS, and the 30mm pancake.
  • There will also be a K-mount adapter, for Pentax SLR lenses (with the K mount) and Samsung's lenses that fit their GX-series SLRs. Some Pentax enthusiasts were hoping the NX10 would have a K-series mount, instead of an adapter, which apparently won't allow for you to autofocus the lens.

Price has not yet been set, but the NX10 will ship this spring.
