Epson's entrance into the home-theater projector arena has long been anticipated. For years, Epson has had the best color-management system of any maker of LCD projectors, and their ability to tame the uneven spectral output of short-arc metal-halide lamps has been impressive.

If you've been following the plasma marketplace, you've surely figured out that there's a lot of product re-selling and "private labeling" these days. It's not unusual for five or more companies to be selling the same 42- or 50-inch plasma panel, albeit with different-colored trim plates and bezels. Some re-sellers even go so far as to put their own processing electronics inside, but these days, that's largely the exception to the rule. There's no end to the companies who are offering plasmas for sale, but only a handful of them actually make the things.

Home Theater's guide to using indoor and outdoor antennas to pick up digital TV broadcasts.

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.

Hitachi's PJTX100 UltraVision front LCD projector replaces the short-lived Home 1, a low-cost, 964x544-pixel design that made a brief appearance earlier this year. I liked many things about the Home 1, but it suffered from very low light output—too low to be practical for most home-theater applications.

One man's quest for the ultimate Super Bowl party included HDTV in every room.

It started out innocently enough, back in January 2000. ABC had concluded a season of Monday Night Football broadcasts in their 720p HDTV format and was putting the icing on the cake with an HD telecast of Super Bowl XXXIV from Atlanta, Georgia. Since I had watched a few of the MNF games in HD, I decided to set up a front projector and an HD monitor and invite some friends and neighbors over to give 'em a taste of sports in high definition. The game turned out to be a big hit. Over 30 folks attended and marveled at the widescreen images from my Sony VPL-VW10HT projector and Princeton AF3.0HD monitor. Never mind that I had to jury-rig an antenna on my rear deck and run coaxial cable into my basement to feed a single Panasonic set-top tuner, then use a video-distribution amplifier to run two component video feeds into my living room and my basement theater. Everyone was amazed at the picture quality and gorged themselves on a feast of wings, subs, pizza, chips, dip, and assorted desserts.

When it comes to selling front projectors into the home-theater market, JVC has always gone its own way. When other manufacturers were jumping into Digital Light Processing (DLP) and high-temperature polysilicon LCD, JVC introduced the direct-drive image light amplifier (D-ILA)—basically, a liquid-crystal-on-silicon (LCoS) imaging device. When others were adopting short-arc metal-halide and vapor lamps, JVC opted for xenon arc lamps to improve white balance.

Key Digital Systems (KDS) is no stranger to the world of video signal processing. They've been manufacturing video scalers for several years, including some models that had more functions than a Swiss army knife.

Flat-screen imaging technologies like LCD and DLP are slowly toppling the cathode-ray tube (CRT) from its pedestal. How much do you really understand about these new ways of watching TV?

It was easy to be overwhelmed with all the plasma and LCD flat-panel displays at CES 2005. But upon closer inspection, there were a few clear trends and some truly significant advances in technology.

The struggle to displace CRT front projectors from their lofty perch continues in the home-theater world. Cathode-ray tubes still produce the most lifelike images, with wide gray scales and excellent contrast, but they require a fair amount of setup, calibration, and periodic maintenance to keep looking their best.
