HDTV Tech

It's funny how everything old is new again. Forty years ago, you might have watched from the backyard as Dad carefully climbed up a ladder to the roof, strapped a bracket onto the chimney, and attached a large T-shaped television antenna so that you could watch those glorious black-and-white (and sometimes color) images from I Love Lucy, Bonanza, The Wonderful World of Disney, Gunsmoke, and other TV programs of that era.

Imagine being able to place that brand-new flat-panel HDTV anywhere in your living room without having to figure out how to hide the video cable that tethers it to your A/V receiver, DVD player, or set-top box. You won't have to imagine it much longer as wireless HD transmission moves from the drawing board to the retail shelves. As always seems to be the case in this industry, we'll go from having virtually no options to having multiple technologies competing for the attention of manufacturers and consumers alike.

You used to be able to buy a TV, plug it into an antenna or cable outlet, and start flipping channels. It was an amazingly simple system. Digital television and its high-resolution subsystem, high-definition television, aren't quite as plug-and-play . . . yet. Antennas only pick up high-def signals in some markets; cable usually doesn't pick them up at all. Satellite seems like a good bet, but it doesn't offer everything. Plus, certain DTV tuners don't work with certain displays. It's enough to drive any self-respecting videophile to drink (not that we'd fault you for that). But there is hope. The following three-step guide is intended to make setting up an HDTV system easier than following that other multistep program. First, figure out what sources are available to you, then find a tuner that works with those sources. Finally, buy a high-definition display that works with that tuner.

When we wrote this feature for last year’s HDTV Buyer’s Guide issue, the flat-panel HDTV market was much simpler. 3D was nowhere in sight, and much of our analysis boiled down to the pros and cons of LCD and plasma technology. This year, 3D is just one of the newer wrinkles in the market. The number of plasmas in the market isn’t what it was just a few years ago, but plasma is not only hanging on, the best plasmas still stake a legitimate claim to being the best flat panels available. With LCDs, manufacturers are aggressively using the backlighting techniques to market the sets. In fact, LCDs are getting more and more sophisticated and offering serious potential value. There’s a lot to learn, so let’s get going.
