Switching scenarios for component video sources.

Switching component video sources is a double-edged sword. For a number of reasons, there's plenty of need for it; however, until recently, it was fairly expensive to do it well (read: without adversely affecting the video signal). Still, there are a number of scenarios in which video switching, transcoding, or distributing high-resolution video (particularly HDTV signals) is important.

A three-step guide to receiving HDTV signals.

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.

The truth behind progressive-scan DVD players.

Conspiracy theories are like computer problems—almost everyone has one. From JFK's assassination to the demise of TWA flight 800, it's rare that everyone will accept the simplest explanation as the truth. Consumer electronics has its fair share of conspiracy theories, as well. They may not be as complex as a Louisiana district attorney's triangulated-bullet-trajectory theory, but they exist, nonetheless. What do you expect to happen when a large number of obsessive-compulsive personalities have too much free time and join a chat room?

. . . especially when it allows you to make the most of your viewing experience.

I occasionally peruse Internet A/V forums to see what the techier web denizens have to say about the latest news and reviews.

One thing I've noticed a lot of lately, especially after our big projector 3fer, is a fixation on black level, with no mention or thought about contrast ratio.

This is a big deal, as black level without contrast ratio can result in some pretty terrible picture quality.

“What’s in a name? That which we call a rose. By any other name would smell as sweet.”

Quick! Name the play! It’s Romeo and Juliet, of course. And it’s certainly one of Bill Shakespeare’s best lines, particularly in the way it encapsulates Juliet’s whole Montague/Capulet dilemma.

My dad called me the other day. He had just rented Avatar and he wanted to know if I had seen it and if the version I watched was in 3D and why his wasn't. A client sent me an e-mail asking whether he could use a new 3D TV to watch regular, non-3D programming.

Starting with the September issue (and now, online), we're adding a new measurement to our objective TV/projector tests. It's called "input lag" and while it's not as important as contrast ratio or color accuracy (which we already test for), it's an important metric for gamers, and anyone who notices issues with "lip sync."

So here's what it is, how we test for it, and what, if anything, you can do about it.

Did you read that headline in Seinfeld's voice? While contrast ratio, black level, and light output all rightly occupy the top of the list of specs one considers when purchasing a new display, color is often completely overlooked.

Good color reproduction usually won't make or break a display, but it can make one that's good into one that's great.

Yet for all its importance, it's rarely understood - and it's regularly done wrong.

Today, 3D has become a de facto feature on almost every higher-end TV and even many projectors, and it continues to make headlines. But the biggest news to come out of the CEDIA Expo trade show this past September wasn’t of the three-dimensional variety. The news that took many attendees by surprise was 4K.
