Update: Wireless HDTV

Digital TV and HDTV have been changing the way we entertain ourselves for a while now: super-lifelike images, integration with computers, and near-effortless access to content are just a few of the things that make it feel like future technology is coming to fruition now.

But, there’s one aspect of HDTV technology that makes us feel like it’s still the 20th Century: all those damn wires to trip on. Your cell phone doesn’t need wires. Why should your TV?

Luckily, there’s a movement in the electronics industry dedicated to establishing a new standard for wireless transmission of high definition audio and video content. It’s called the Wireless Home Digital Interface (WHDI) Special Interest Group, and has been established between Sony, Samsung, Sharp, Motorola, Ammion, and Hitachi. They are hoping to implement the new standard in a video-modem that can transmit 1080p HD content, wirelessly on the 5GHz band, throughout several rooms in a house.

For more information, check out WHDI’s news page or their FAQ page.



What’s Hot Now: Samsung LN46A650

Samsung LN46A650 HDTVSamsung’s new 120 Hz, 1080p, super-fast and super-sharp A650 is winning huge praise from consumers for its performance and quality. None of its specs are much different from the other top-of-the-line LCDs, like those from Sony and Sharp, though. So why is the Samsung so hot?

A high performance HDTV is a fickle beast, and those exciting new features sometimes come at the expense of something else, like reliability or display problems. The LN46A650 seems to be one of the first HDTVs to blend all the latest features into a good, solid, reliable package.

Is Plasma HDTV Coming Back?

The answer is no, of course, since Plasma didn’t really go anywhere.

Sales of LCD sets have been increasing fast over the last few years, mainly because LCD technology has enabled builders to make sets in the 40 and 50 inch size range that can compete well with Plasmas, in terms of picture quality and cost. In the past, LCD dominated the smaller sizes and Plasma dominated the larger, so this trend seemed like a death knell for Plasma.

However, North American sales of HDTVs have surged since last quarter, with Plasma sales growing about 17% faster than LCD. One possible cause for this is the emergence of smaller sizes, like the Vizio 32 inch Plasma and the Panasonic 37 inch UK Series Plasma.

Should I Wait for an OLED HDTV?

One of the big questions most HDTV buyers have these days is: which of the three most popular technologies (LCD, Plasma, DLP) should I choose? Or, should I wait for the next big thing I’ve been hearing about, OLED (Organic Light Emitting Diode)?

The answer is no- unless you’re willing to wait several years. Buy your favorite HDTV that’s on the market now, and when that one wears out, you will probably be seriously considering an OLED. Here’s why:

  • OLED screens are made with a synthetic organic substance, which is similar to the chemical that lights up fireflies and deep-sea fish. This substance shines bright and cool, doesn’t need a backlight like LCD sets, and so consumes very little energy.
  • The construction process allows OLED screens to be extremely thin- an 80-inch HDTV might be as thin as a quarter inch.
  • The OLED screen will be more durable, will handle greater temperature ranges, will change images quicker, and will even be flexible.
  • They will eventually be produced in much larger sizes then current HDTV sets, and should be cheaper when production gets up to a certain level.

There are still a few bugs to work out, though. Here’s an example: the OLED screen is made of several layers of the organic substance, each of which is responsible for displaying a different color. The red and green layers have proven to last up to 40,000 hours in some laboratories, but researchers are having trouble getting the blue layers to last more than 4,000 hours in prototype screens.

The bugs aren’t preventing the big HDTV companies from spreading the word, though. Here are some recent updates and press releases on OLED:

Sony Updates the Bravia XBR HDTV

Sony makes what is arguably the highest-quality LCD HDTV on the market, the Bravia XBR series. Over the past few years, the latest model has been the XBR, XBR2, XBR3, XBR4, and XBR5. Now, to the surprise of no one, they have named their new model XBR6.

The word on the street is that this one has a little bit better picture than the XBR4 and 5, and a lower introductory price, but it is lacking a few of the advanced features. The first ones to be available online are the 32 inch, at about $1100, and the 37 inch at about $1500.

NASA to Release Updated Footage for HDTV

NASA (the National Aeronautics and Space Administration, of the US government) has recently restored hundreds of hours of space footage from the Mercury, Gemini and Apollo missions in the 60s and 70s. Much of this footage had only existed on film, and has been converted to digital files with HDTV resolution.

The main archive for NASA’s HD video is here: http://www.nasa.gov/multimedia/hd/HDGalleryCollection_archive_1.html

The restored footage might not be on the site quite yet, but that’s where it will be available soon. And for a little more information, check this news item or NASA’s Home Page.

To see this footage in its full glory, you’ll have to connect your HDTV to your computer. For some tips, check here: Connecting your HDTV to your PC 



The HDTV Experience: Buying Online

Buying a big-ticket item like an HDTV through the internet is a pretty scary prospect for most people. There are several anxiety issues: Will my stuff get damaged in shipping? What if I have to return it? Will I waste the better part of a day (or two) waiting for the delivery truck? And isn’t it crazy to send several thousand dollars into cyberspace, to someone who may or may not even be a real person?

Those are all reasonable fears. But, the last one is not as reasonable as it was back in the 90s. The rise of major online retailers like Amazon.com has raised online customer service standards to a level where the overall experience, though different, is in many ways better than the experience at your neighborhood electronics store. Let’s look at some of the concerns behind buying online:

  • My HDTV may be damaged in shipping. It’s certainly possible. But the policy of Amazon and most other online retailers takes this into account, and gives you several ways to deal with it. With their standard shipping, the delivery person will typically help you take the set out of the box, wait for you to plug it in and see if there is any shipping damage. If there is, it’s a no-brainer- the set goes back and you get a replacement immediately.
  • The set may be damaged in a way that is not immediately obvious. Even if you don’t notice anything wrong with the set right away, you can still send it back for a replacement within 30 days, and Amazon will pay for the shipping. And when you think about it, this problem is equally likely when buying from a physical store: the set had to be shipped to the store in the first place, and the store is certainly not going to test every unit for every kind of defect. That means you’re the “test pilot” whether you buy from Circuit City or Amazon.
  • I will have to wait all day for the delivery truck. Yeah, this one’s annoying. But fighting traffic and hanging around in a big-box electronics store for several hours can be infinitely frustrating as well.
  • It’s easier to talk a salesperson into a lower price. If you’re a genius at haggling low prices out of retail sales managers, you might enjoy the buying process more at a physical store. Unfortunately, while most salespeople can be talked into matching the price you found down the street, they will rarely match the best price you can find online. Beating the other neighborhood stores is one thing, but beating every store on the internet is quite another. And to top it off, Amazon will actually give you a rebate on your purchase if the price of your HDTV goes down within 30 days after your purchase.
  • It’s hard to trust a faceless online merchant. Given the speed with which the world is changing, that’s understandable. The best way to get around this one is to start spending more time online, do your research, interact with real people in chat rooms, read industry newsletters, and so on. Once you become aware of the potential pitfalls and the ways to safeguard against them, buying online will feel as natural as putting money in the bank.
