I've written articles in the past explaining various TV technologies, including the differences between 720p and 1080p and 120Hz and 240Hz LCD TVs. But with Samsung, LG, Sony, and other manufacturers pushing so-called LED TVs these days, it's high time that I--with an assist from our resident video guru, David Katzmaier--sort through all the marketing mumbo jumbo and provide some insight into just what an LED TV is. Here goes.
1. An LED TV is not a new kind of TV.
I appreciate a good marketing ploy as much as the next guy, but an LED TV is just an LCD TV that's backlit with light-emitting diodes (LEDs) instead of standard cold-cathode fluorescent lights (or CCFLs). And while they've become best-known this year with Samsung's ultrathin models, LED-backlit LCDs have been on mainstream store shelves since 2007, when Samsung's LN-T4681F debuted.
Unlike plasma and OLED, which are emissive technologies where each pixel is its own discrete light source, LCD is a transmissive technology where each pixel has to be illuminated from behind, or backlit.
2.There are two types of LED backlighting.
Initially, LED-based displays like the Samung LN-T4681F were backlit by what's referred to as a "full array" of LEDs behind the LCD across the back of the panel. But to create superthin TVs, engineers needed to eliminate that extra layer of LEDs and move it to the sides of the display. With this form of backlighting, the LEDs are affixed to all four sides of the TV and light is projected inward to the middle of the TV via "lightguides." These types of TVs are commonly referred to as "edge-lit" LED-based LCDs.
Samsung is the main maker of such sets this year with three series of edge-lit sets, although Sony did release one model earlier this year, the KDL-40ZX1M, and has another flagship series, the KDL-XBR10 models, waiting in the wings. Samsung, Sony, Sharp Toshiba, LG, and Vizio all have non-edge-lit, or "full array" models, available today. See our comparison of edge-lit vs. local dimming for more info.
3. Of the two, local dimming can produce deeper black levels, but also creates "blooming."
Local dimming LED backlights can dim or turn off individually as needed.
The type of backlighting can impact how deep a shade of black a TV can produce. All current LED-based LCDs with rear-placed, "full-array" LED backlighting--except the Sharp LC-LE700UN series--feature a technology called "local dimming." With local dimming, specific areas of the backlight can be dimmed or brightened when different areas of the picture get darker or brighter.
With fluorescent backlighting and edge-lit LED backlighting, by contrast, the entire backlight dims or brightens at once, if at all.
Being able to dim specific quadrants helps reduce the amount of light that leaks through to darkened pixels, and the end result is blacks that appear darker and more realistic. Since black levels are crucial to contrast ratio, the deeper the blacks, the more the picture--and colors--appear to pop. Also, the image as a whole will seem crisper. A great example of local dimming done right is Samsung's UNB8500 series, which is one of the best-performing TVs we've ever tested.
One downside to local dimming is an effect called "blooming," where brighter areas bleed into darker ones and lighten adjacent black levels. ... Read more
Critics of Blu-ray often talk about how expensive the discs are, but in recent weeks, a growing number of Blu-ray movies have become more affordable, with several dipping below the $15 price point and some even slipping in at $9.99 on Amazon.
Cheap is popular these days and, not surprisingly, a lot of these bargain-price titles end up on the bestsellers list on Amazon. But when it comes to owning discs, most people have become pretty discerning, and don't just buy anything because it's cheap. With that in mind, we've culled down the list of bargain titles and selected 15 we think are worth owning.
As always, it's important to mention that taste is subjective, and if you don't like our picks, call us out and make your own suggestions in the comments section. If you're persuasive enough, we'll edit the list and swap in new titles. And as new budget Blu-rays come out, we'll also update the list. (Note: The discs on the list all were priced at less than $15 on Amazon at the time of this writing. Naturally, those prices are subject to change.)
For reference, here are the discs we considered but ultimately didn't include this round: "Bullitt," "Unforgiven," "Beetlejuice," "V for Vendetta," "Swordfish," "A Clockwork Orange," "I am Legend," "Fugitive," "The Road Warrior," "The Dirty Dozen," "Enter the Dragon," "Risky Business," "Dirty Dancing," "The New World," "Top Gun," and "Being There."

A few years ago, we used to do a feature highlighting some of the top DVDs that made your home theater really look and sound like one. Well, with Blu-ray in full swing, we thought it high time to come up with a similar roundup of our favorite Blu-ray Discs that will help show off your home theater in all its glory.
While my face is at the top of the column, the list was compiled with input from editors John Falcone, Matthew Moskovciak, and David Katzmaier, who look at a lot of content in their day-to-day testing of products. We also keep an eye on AVS Forum's Blu-ray picture- and audio-quality threads and have always appreciated the site's "tier" rating system.
This list is not set in stone, and we'll be adding and removing discs as new ones come out. As always, feel free to make comments and suggest your own personal favorites. They may get added to the list in the future.
Also: If you're someone who likes demoing your system and skipping around between scenes, you'll want a fast Blu-ray player. Right now, the fastest players we've tested are the LG BD390, Sony PlayStation 3, and the Samsung BD-P3600. Though not quite as fast as its step-up sibling, the Samsung BDP-1600 is among the fastest sub-$300 players we've tested. (See CNET's full list of best Blu-ray players.)

On her way back from the airport the other day, our photo editor Sarah found a Kindle in the back seat of a New York City taxi cab. Being the honest person she is, she asked me if there was any way to get it back to the owner.
Well, it's actually not that easy to track down the owner of Kindle, especially if that person has a fairly common first and last name, as the owner of this Kindle does. We actually e-mailed him at the Kindle address that's registered to the device but it doesn't appear that you can get your @kindle.com e-mail unless you have the device.
Addtionally--and rather tragically--the person who bought this Kindle never inputted his personal information into the device. The link to "edit personal info" can be accessed from the "Settings and Device Information" tab when you click the menu button from the Kindle's home screen. On this Kindle, the box is empty.
Lesson 1: If you own and Kindle or another device that allows you to enter your personal info into it, do it, because while a lot of people would just deregister a lost Kindle and make it their own without ever trying to track you down, there are some people who want to return stuff that doesn't belong to them.
Lesson 2: Get a protective case for your device. The naked Kindle Sarah found has a small gash on the front (we're not sure if it got stepped on, sat on, or what) and it really does ruin the reading experience.
Now, we thought of calling Amazon and asking customer service reps for some possible info on the owner, but we've heard that Amazon doesn't like to give out info on Kindle owners. In fact, the New York Times recently wrote a story about how one owner of a lost Kindle pleaded with the company to brick his device so the person who found it couldn't use it. However, Amazon will only deregister the device to prevent your account from being accessed, but it won't keep someone from reregistering it. (The article talks about how there should be some way to authorize use from one owner to the next in the case the device is lost or sold.)
Coincidentally--or not--Ars Technica wrote a very similar story a week earlier. (Good headline I'd like to use someday: "Did the Times rip off the stolen Kindle story?")
But I digress.The purpose of this column isn't about ribbing Amazon or the Times but about taking a shot at finding this Kindle's owner.
Here's a hint. The device's name is "John's Kindle." So, if you're a John who lost your Kindle recently in New York, e-mail me through the link in my bio and we'll see if your last name matches up to the one on the device.
If you're name isn't John, and just want to comment on losing a Kindle, an iPhone, or another device you cherished, feel free to comment. We'd like to hear about your loss whether it has good ending or not.
In recent days, a few blogs have picked up on the fact that the battery on Sony's upcoming PSP Go will be sealed into the unit and not be user-replaceable, just as it is on all of Apple's latest portable devices and plenty of other new gadgets. The integrated battery isn't new news. But what caught people's attention was an old quote from John Koller, Sony's director of hardware marketing, which PlayStation Insider recently ripped off from a June Ars Technica article that had Koller explaining that the move to a built-in battery was a least partially designed to thwart pirates.
The PSP Go's embedded battery is a security feature.
(Credit: Levelup.cn)In case you don't know the history behind PSP piracy, it goes something like this: For the original PSP-1000 and second-generation PSP-2000, Sony had a secret "backdoor" system for resuscitating frozen or "bricked" PSPs. The process involved replacing the common PSP battery with a special one that unlocked the system.
Alas, the secret didn't last long, and hackers developed their own custom battery (the appropriately named Pandora's Battery) and firmware that allowed anyone to run illicit "ripped" versions of UMD games along with home-brew applications and PSOne titles that had been converted to run on the PSP. Those in the home-brew community maintain that they're just interested in fully accessing the products they've purchased and that pirating games isn't what their creative efforts are about. But the offshoot of the whole movement has been a flourishing trade in pirated games.
Nintendo faces similar problems with hacked DS systems, but a quick check of The Pirate Bay Top 100 handheld games reveals that the majority of the illegal downloads on the list are for the PSP. As I write this, more than 2,000 people are illegally downloading Dissidia: Final Fantasy, the top game on the list.
It's also worth noting that a counter on another site says that 81,000 people have already downloaded a recent custom firmware upgrade that will potentially allow modders to play that pirated version of Dissidia. A couple of competing custom firmware upgrades are out there, both of which appear to have been created by European hackers, including the infamous Dark Alex, a Spanish programmer who hasn't been heard from for a while. Some speculate that Sony has somehow neutralized Dark Alex either through legal threats or compensation, but Sony reps tell me that while they're aware of him, they [Sony], "Really have no relationship with him."
Although Sony hasn't said that much publicly about the piracy issue, it's acutely aware that tens of thousands of people--and quite possibly hundreds of thousands--never pay for games. Over the years, it's been trying to stay ahead of hackers with a steady stream of new firmware upgrades and additional security features incorporated into the PSP-3000 and the game discs.
In a response to some questions I submitted to Sony for this article, Koller says that, "Piracy is an industry-wide issue that ultimately is bad for consumers. We're continuing to take proactive steps to address the issue of piracy and to minimize its impact on the PSP, from both a legal and technical perspective. For example, firmware updates enable us to apply security patches and enhance or add new features."
Many, if not most, new PSP releases going forward will require you to install Sony's latest firmware to run the title (the firmware comes on the game's UMD disc). At this juncture, hackers appear to be a step behind Sony, though message-board posters on sites like psp-hacks.com remain confident Sony's security measures will be breached and that the real game begins when Sony releases its 6.0 firmware (Sony hasn't announced a launch date yet).
If there's an irony in all this it's that that the UMD format was supposed to prevent piracy and now Sony is seeing the move toward digital downloads as an opportunity to keep pirates at bay. Although a bit late (many argue that the PSP should have skipped physical media from the get-go), it's the right thing to do. That said, Sony does face some serious challenges in making the transition to a UMD-less platform.
- The $250 price tag on the PSP Go is too high (this is fairly self-explanatory, but it's unclear why Sony would bring out a more expensive device unless it was actually being cautious and didn't want to sell as many PSP Gos as it could if it were priced at $179, like the current PSP-3000 is).
- It's unclear just how much people are willing to pay for downloadable games. For a UMD PSP title, you're looking at $30-$40, but the top end for a downloadable game is $29.99 max for a AAA title and $19.99 for AA stuff.
- Currently, there's no way to trade in digitally downloaded games. As it is, popular PSP titles don't fetch all that much money at Gamestop or Amazon. But they fetch something, and trade-ins are how a lot of people help finance the purchase of new games.
Koller says that based on Sony's consumer research, there's strong demand among PSP owners for digital content. "That's why we're launching the PSPgo, which specifically invites consumers who prefer digital content to download games legally," he says. "We're offering a full spectrum of games for PSP owners to download, from bite-sized games in the new 'Minis' section on PlayStation Store to full, large-scale experiences like Gran Turismo."
As far as the pirates go, if history is any indicator, Sony probably won't be able to stop hackers from cracking the Go. (Koller was smart enough not to declare it unhackable; he merely said, "The PSP Go is going to make things tougher on the pirates.")
Ultimately, the company's best defense against piracy may be to offer good, affordable sub-$20 games and applications or perhaps even move to a monthly rental/subscription model that allows you to check out titles for 30 days, with an option to buy at the end. To get to where it wants to go, Sony not only needs to stay one step ahead of the hackers, but it needs to stay one step ahead of the competition. Occasionally, that requires thinking differently.

Recently, my colleague Rafe Needleman wrote a column titled "Why consumers won't buy tablets." The article was a direct reference to the long-standing rumor that Apple may be releasing a slate-style, jumbo iPod Touch this fall. Rafe doesn't really believe Apple would be misguided enough to release a tablet and that if it does put one out in the rumored $700 to $800 price range, "it will die." He also believes that, "This whole category is a nonstarter."
I tend to agree with Rafe on a lot of his points. I think tablets and tweener devices--like Ultra Mobile PCs (UMPCs)--that are too big to put in your pocket, cumbersome to operate, and overpriced, are problematic and have no place in the marketplace.
The reason why Netbooks have been successful is that they're cheap, and their form factor makes sense, especially for those looking to take a basic, lightweight computer out with them on the road--or just out to the patio. It's a pretty simple equation and you'd think that Apple would just follow the Netbook trend and come out with something that didn't break the mold but was sexier, a little zippier, and cost an extra $100-$200 in so-called Apple tax. What I'm talking about is a 10-inch $600-$700 Apple Netbook with a keyboard.... Read more

One of the reasons people like to give for not buying a Blu-ray player is that there just aren't that many Blu-ray discs out there and that a lot of great movies haven't come out on Blu-ray. That's not totally true. There are a lot of movies out on Blu-ray--over 2,000, in fact--and more are being released every month, including "Gladiator" and "Braveheart" in September and the "Lord of the Rings Trilogy" in November.
That said, plenty of movies have yet to be given the Blu-ray treatment. A good portion of those movies are bad or inconsequential, and you probably don't care whether they make it to Blu-ray or not (or they're fine on DVD). But we're concerned about the good stuff that's not available, which is why I've put together this list of key movies that aren't out yet on Blu-ray.
To be sure, some of you may take issue with my picks. And I probably missed a few that should have made the list. But like I do with my Top 25 must-have Blu-rays list, feel free to express your opinions and if you have a legitimate case, I will gladly update the list with new picks.

CNET News Poll
According to various rumors and reports, Apple's got a new slate-style Netbook in the works that may be announced as soon as next month. While we have no confirmation from Apple--or anybody else--that such a product really exists, that doesn't mean we can't do a little market survey and ask you what the thing should be called.
If the rumors are at all on target, the final product will look something like a jumbo iPod Touch. However, what's interesting is that such a PC would most likely be a crossover product for Apple and straddle several product families, includes iPods, MacBooks, and maybe even Apple TV. So, is it part of one of those families or a whole new category unto itself?
Only time will tell, but for now you can cast your vote in our poll of popular candidates or write in your own choice in the comments section. We strongly doubt we'll have any influence whatsoever over Apple's decision, but, hey, people at Apple do read CNET. At least a couple do anyway.
In a recent MarketWatch article on Microsoft's struggling Zune portable media player, reporter John Letzing got an interesting quote from George Kurian, a vice president at Tradition Capital Management LLC, which owns Microsoft shares.
"Microsoft should abandon Zune and follow Apple's strategy to try to make its presence felt in the high-growth smartphone sector," Kurian said. He then went on to suggest that the easiest way for Microsoft to do that would be to buy Palm.
Palm and Microsoft have hooked up before, so why not quit fooling around and really tie the knot?
(Credit: Sprint)"Microsoft might pay tens of billions of dollars for Yahoo; it could pick up Palm instead for just $1 billion or $2 billion and then spend several hundred million more on transforming the Pre's user interface into a mobile OS that can run on phones made by multiple vendors," Manjoo wrote. "Microsoft would also gain a loyal Palm audience--and a base of developers looking to create apps for the device. And then Microsoft would have money left over to buy other software companies--start-ups and established firms that power the next generation of devices, or that are pioneers in the selling online software to companies."
More recently, Gary Marshall over at Techradar.com took a whack at why Microsoft should ante up for Palm. He pointed out that buying Palm "would bring the Pre's designers to Windows Phone, and it would annoy Steve Jobs, too" because the Pre team includes Jon Rubenstein, former vice president of Apple's iPod division, and former Apple developers' champion Chuq Von Rospach. Also, in the same article, Andrew Kitson, senior analyst with Juniper Research, said that a WebOS-powered smartphone would be a nice item to sell in Microsoft's forthcoming retail stores.
What's interesting about this growing cry for Microsoft to buy Palm is that a lot of people seem to be rather dismissive of Microsoft's own smartphone operating system, Windows Mobile. ... Read more
The iPod Classic may be an endangered species.
(Credit: Apple)If you've read the stories on Apple's latest earnings, you may have noticed that Apple Chief Financial Officer Peter Oppenheimer took the time to break out the sales of each model in the iPod franchise, which is seeing year-over-year declines for the first time in its history. In her piece, our own Erica Ogg wrote:
"During the third quarter, Apple sold 10.2 million iPods, compared with 11 million a year ago. It turns out that the shifting appeal of the Shuffle, Nano, and Classic model iPods are to blame. But Apple apparently saw this coming." She then goes on to quote Oppenheimer, who says those declining sales are "the reason we developed the iPod Touch. We expect our traditional MP3 players to decline over time as we cannibalize ourselves with iPod Touch and iPhone."
As rumors continue to circulate that Apple will introduce new iPod models this fall (as it traditionally has), the big question is whether the iPod Classic becomes the odd iPod out. In a recent MP3 Insider podcast, CNET editor Donald Bell points out that orders for new Samsung hard drives that would go into an updated Classic appear to be nonexistent, according to Ars Technica and Apple Insider. And shortly after the earnings were posted, TechCrunch writer MG Seigler asked whether the iPod as we know it is dying.
The prevailing bet among iPod followers is that the Classic may stick around for a little while, but it probably won't be upgraded and will be quietly put out to pasture. ... Read more
