From a recent article in the Los Angeles Times:

“A South Korean Company aiming to transform the way Americans experience movies at the multiplex is bringing its ‘4-D’ technology to Los Angeles.”

What’s 4-D? The technology is actually called 4DX, and instead of just picture and sound it adds, as needed, moving and vibrating seats, wind, strobe lights, fog, rain, and scents, all of them supporting what’s happening on the screen.

Some time back I was in the South Bay area of Los Angeles to pick up some gear at our California headquarters in El Segundo, some 30 miles from my home in the Valley (that’s the San Fernando Valley, the pre- and near post- WWII home to hundreds of western movie shoots and, more recently, to freeways, mega suburbia, and Valley Girls). Even Angelinos may not be aware that El Segundo got its name from being the site of the second Standard Oil refinery built on the West Coast. As far as I know there’s no town immortalizing El Primero or El Tercero.

But I digress.

Ultra HD Blues…and Reds, and Greens I recently completed a review of Sony’s new VPL-VW600ES Ultra HD (4K) projector. This isn’t a sneak peak—that would cannibalize our coverage. The review will appear in the May 2014 issue of Sound & Vision. But for those who can’t wait, I’ll just say here that while the 600ES isn’t the champ in all respects, it’s still, overall, the best-looking projector I’ve yet had in my home theater.

I recently completed a review of The Right Stuff on Blu-ray, which will appear in an upcoming issue of Sound & Vision as well as on this website. Since space is limited in my print review, I've decided to dedicate this blog to how I evaluated the 96kHz audio offered on the disc.

Last year, Dolby announced a new variation on its TrueHD audio codec for Blu-ray, a process that uses 96kHz upsampling of the. Its purpose is to eliminate some common digital artifacts (see Geoff Morrison's article for a more detailed explanation of how this works).

The process has only been used to date, however, on a few releases. The Right Stuff, originally released on Blu-ray in November 2013, was supposed to be one them. Through a mastering error, however, the process was not engaged. Now, two months later, Warner Brothers has re-released the film with the 96kHz upsampled soundtrack.

The International CES for 2014 is history. But don’t call it the Consumer Electronics Show any longer. Just CES will do. The CEA, which runs the show (I guess it’s still OK to call the CEA the Consumer Electronics Association) wants to drop the long form, probably so we can now call it the CES show without being redundant.

In any case, a consumer electronics show by any other name is still a consumer electronics show. And it continues to be the biggest game in Las Vegas every January. Over the years it has outgrown its roots as an audio/video show to encompass all manner of electronic detritus. Computers and gadgets of all sorts now deck the halls. After the show I heard something about a Bluetooth toothbrush, but I missed out on seeing it. My life is now without meaning.

If you’re a fan of science fiction and haven’t heard of the TV series Farscape (1999-2003) you don’t get out much. If you’re not a sci-fi fan, this series might just make you one. It offers more compelling characters, action, humor, drama, weird plot twists, sudden mood shifts, poignancy, and stunning performances than any other dozen TV shows you might name.

It all begins when astronaut John Crichton encounters a wormhole on an experimental mission. He’s flung to a distant quadrant of the galaxy, encounters a gigantic vessel nearby, and docks with it. It turns out to be a living ship, know to the locals a leviathan, operated by a bonded pilot. The ship’s occupants are alien prisoners escaping from their captors. The latter, the Mr. Bigs in this area of space, call themselves the Peacekeepers, and from all appearances (externally at least) appear indistinguishable from humans.

Lasers, or Light Amplification by Stimulated Emission of Radiation, have been with us for half a century. A laser produces a highly focused (spatially coherent) beam of light having a very specific wavelength, the latter depending on the design and application. They’re used in medicine, industry, laser printing, barcode scanners, CD, DVD, and Blu-ray players, laser light shows, and innumerable other applications.

Lasers can also be used as a light source for digital projection. While this is still under development, we’re likely to see it first in movie theaters. Lasers can not only produce a much brighter image—which can help overcome the dimness of 3D presentations—but also offer cost benefits to theater owners. Conventional xenon lamps are expensive to replace, and have a useful life of perhaps 1000 hours (some theaters try to stretch this as much as possible, often with negative effects on picture quality). A laser light source can stretch this by at least twenty-fold or even more. While replacement lasers will likely be significantly more expensive to early on, they’ll still be cheaper per hour of use. Another possible cost saving might come from using a centralized “light farm,” with the light from a single remotely located bank of lasers routed to multiple projectors via fiber optics.

A week ago this past Monday I was fortunate to be one of Chinese consumer electronics manufacturer TCL’s guests at the premier of Ender’s Game at the TCL Chinese IMAX Theater in Hollywood. (The theater is still best known as Grauman’s Chinese; see my earlier blog here about TCL’s purchasing and remodeling this classic movie palace into an IMAX theater with stadium seating).

CEDIA began its annual event in 1989. At that time it was launched in a modest venue full of table-top exhibits and educational seminars, with a strong emphasis on the latter. This was appropriate, as we all had a lot to learn about home theater.

I’ve been attending CEDIA since 1994, when then Stereophile publisher Larry Archibald decided it was time to begin a new publication dedicated to the burgeoning home theater business—the Stereophile Guide to Home Theater. But even in the first year or two I attended, accompanied by Archibald, the Guide’s founding editor, Lawrence B. Johnson, and the requisite marketing crew, you could cover all of the exhibits in a couple of hours.

I don’t think we’re in Kansas anymore. Follow the yellow brick road. And your little dog, too! I’m melting! Ding dong the witch is dead. Pay no attention to that man behind the curtain. Lions and tigers and bears, oh my!

The Wizard of Oz has likely contributed as much to the American lexicon as anything prior to Star Trek. (Just kidding— though “I’m giving ‘er all she’s got, Capt’n, He’s dead, Jim, Engage, Fascinating, Make it so, and I’m a doctor, not a bricklayer” do have their loyal fans.) The movie wasn’t a huge hit when it first opened in 1939, but it made up for it years later, particularly starting in the 1950s when it became an annual TV event.

On July 11, LG Electronics launched its latest 4K Ultra HDTVs at the Video & Audio Center, a major electronics retailer in Santa Monica, CA. The new LA9700 series includes two models, at 55- and 65-inches (diagonal) and selling for $6,000 and $8,000, respectively.

Despite all the talk about 4K (or Ultra HD) displays, there are already a bazillion hours of “standard” 2K HD programming out there in videoland. Consumer 4K sources will be slow in coming, and they might well arrive over the Internet. The question remains as to whether or not the inherent data rate limitations of streaming video could dilute or eliminate the supposed benefits of 4K resolution—apart from the marketing hype.

Over the next couple of years, therefore, and assuming that 4K sets take fire in the marketplace, the smart money will be on upconverting 2K sources to 4K. No form of upconverting can add real resolution; genuine Ultra HD starts and ends with 4K resolution. Nevertheless, we expect plenty of action on the 2K to 4K upconversion front. Since consumer 2K is largely (though not entirely) 1920 x 1080 pixels, and consumer 4K is 3840 x 2160, it would appear that such upconversion might simply involve taking the content of each 2K pixel and quadrupling it (with no added enhancement) to fill a 2 x 2 pixel area on the 4K display. But that will gain nothing in subjective resolution, and may actually reduce image quality due to the added processing required. Most upconversion, therefore, will likely include enhancement and/or other digital manipulation, designed to both eliminate possible upconversion losses and better simulate the look of true 4K.

Last week Sony put on its best April clothes and entertained the foreign press in Los Angeles. Consumer electronics scribes attended from the U.K, Germany, France, the Netherlands, Denmark, Norway, Australia, New Zealand, and likely others that I (with apologies) can’t recall. Only a few of local CE press were in attendance, including your humble reporter.

In my review of Samsung’s flagship UN75ES9000, 75-inch LCD-LED HDTV, I remark that potential buyers should beware of bad demos of this very expensive set ($9000). Such a demo could make it very difficult to justify the expense.

In our experience, most active 3D glasses are sensitive to head position or, more precisely, head tilt. With most of them, however, the effect is minor and limited to a slight darkening of the picture.

But Sony's active 3D glasses, up to now, have been different. When using the company's HDTV 3D glasses, a 3D image on the Sony displays we've tested doesn't darken as you tilt your head from side to side. Instead, the left and right images break up, producing significant 3D crosstalk or, as this artifact is more colorfully known, ghosting. In addition, the Sony's 3D color varies with head position, shifting reddish with a tilt in one direction from vertical and bluish in the other. The latter effect makes it impossible to do a reliable 3D calibration; one eyepiece of the 3D glasses has to be placed over the lens of the measurement meter for a 3D calibration, and even a slight tilt can affect the result. Fortunately, the Sony 3D sets we've tested recently have produced visually satisfying 3D color even without a 3D calibration, though it's unlikely to be accurate. Nevertheless, the head-tilt ghosting and color shifting are annoying.
