LATEST ADDITIONS

One of the few loudspeaker-related audio demos on the floor at South Hall was the DTS demo of 11.1 surround with extra channels for height and width enhancement. It actually started with a mere 7.1 movie demo and worked its way up to footage of two savvy musician slash sound designers using a combination of acoustic instruments and electronic processing to create a height- and width-enhanced soundscape. The instruments included one that combined the functions of bass violin, cello, viola, and fiddle. A tree was also used as a musical instrument. It was noteworthy that the demo relied on 11.1 more for aesthetic effect (hmmm, that sounds nice) than for realism -- that is, an evocation of something that happens in the real world and is reproduced convincingly. From our seat in the back and off center, the effect was pleasing but not something we'd cite as grounds for adding numerous speakers to a basic 5.1 surround system. However, our colleague Josh Zyber saw another DTS 11.1 demo at Nobu two nights prior and said it was very impressive, with strong imaging in places you wouldn't expect. The pic, incidentally, is what folks saw while waiting in line for the 11.1 demo: other showgoers in raptures over DTS headphone technology.

What to our wondering eyes should appear on the floor of South Hall but the Grey Lady herself, The New York Times, touting her apps for computers, smartphones, e-readers, and of course this year's particular CES obsession, tablets. The paper's show coverage also refers to (other) media companies chasing partners at this year's CE extravaganza.

LG opened the "press day" by announcing its line of "Smart" products. Smart appears to be the company's new go-to word for many of its new products, ranging from Smart washers, dryers, ranges, and refrigerators ("Honey, the fridge says we need milk and ice cream"), to HDTVs, with cell phones and other devices occupying the vast middle ground in between.

To touch briefly on that middle ground, there was prototype of an LG mobile 3DTV that can be viewed glasses-free (autostereoscopic—easier to do for a single viewer). And there's a new LG smart phone, the Optomus 2X, said to do full 1080p. Better sit close.

But it's LG's TVs that interest us most. There are 31 new LG LCD sets, 10 of which are 3D. The Cinema 3D sets employ LED edge lighting. Three "Nano" 3D sets have full LED backlighting with local dimming. Nano technology, which is new this year, employs smaller LEDs imbedded in a membrane that also incorporates the required diffusion, making the entire structure thinner and, presumably, more easily and efficiently produced.

There are also 12 new LG plasmas, 8 of them 3D.

LG's Smart TV technology, used in many of the higher end models, is a new menu layout that simplifies use of the sets' extensive Internet features. In addition, the new LG ST600 module/set top box, available separately, can bring SmartTV to any HDTV with an HDMI input. Another approach to adding this feature to your existing HDMI HDTV is the new BD690 3D Blu-ray player, which includes an on-board 250GB hard drive plus the SmartTV platform.

But the big LG story is the use of passive glasses in many of the company's new LCD 3DTVs, rather than the active shutter glasses now employed in most current 3D sets. LG calls its passive glasses technology FPR, for Film Pattern Retarder. The sets in the LG lineup that will continue to use shutter glasses include all of the Nano models (and all of the plasma sets as well). There are many upsides to passive glasses, but downsides as well (see the following blog entry).

No prices were quoted, but all of the new sets should begin shipping by early spring.

One real advantage of LG's passive glasses technology is the lighter, cheaper passive glasses, shown here in this lightheaded demo setup. Notice the flip-down glasses on the right, for eyeglass-wearers. The FPR technology employs circular polarization, so you can tilt your head without the image fading out.
