In 2002, the video world was just getting comfortable with component analog video. HDTV and DVD were only starting to acquire mass-market status. We were using three separate video cables to connect our shiny new HDTVs to our best sources. Add to that up to six audio cables to our A/V receivers. This forest of cables wasn’t heaven (except to cable vendors), but it worked, and it provided most viewers with their first real taste of high-quality video. We also had DVI, a standard for digital video borrowed from the computer world. But because its clunky connector only carried video and not audio as well, it never achieved critical mass.

In May of 2009, Home Theater ran an article titled “BD-Live in Action” with an overview of the Internet features available on Blu-ray. Even though that piece was written a good three years into the high-def format’s life, the BD-Live aspect was still very much in its formative stages. Many of the Internet features available at that time were gimmicks or filler material. Few could be classified as essential to the experience of owning a Blu-ray Disc. The article concluded with the statement, “We’ve only started to see the building blocks of BD-Live’s potential. Now is the time for a true innovator to step in and show us what it can do.”

You know the drill. You’re just getting into the latest action blockbuster on your new home theater rig when a still, small voice wafts gently into your SPL-addled ear. “Isn’t that a bit loud?” Or perhaps the voice comes screeching in from another room. “I can’t hear myself think in here.” Or there’s a knock at the front door from the men in blue, demanding that you surrender your assault rifle in exchange for a fun stay in the slam with Tony the Hammer.

There’s more that goes into making a good display than accurate color, but it’s certainly one of the biggies. Color in a video display may seem like a relatively simple subject, but it’s not. In this Gear Works, I’ll outline the two most important factors in assessing and measuring the color accuracy of the HDTVs we review—color tracking and color gamut. I’ll also show you how we present this in the HT Labs Measures graphics that accompany our reviews. This article will shed some light on what these important measurements tell us about the color accuracy of the displays we test here at Home Theater.

For all the dramatic improvements they’ve given us in the picture and sound quality of movie playback in our homes, sometimes it feels like the new high-definition disc formats—both Blu-ray and HD DVD—also make our lives needlessly complicated in some respects. Case in point is the process of getting high-resolution surround sound audio from the disc player to an A/V receiver or processor. Let’s be frank here and admit that, in this regard, things were a lot simpler with standard DVD, where there was far less confusion about the different audio formats and hardware hookup requirements.

Nestled deep within the corridors of the sprawling NIST (the National Institute of Standards) campus lives the Flat Panel Display Lab. This special facility is dedicated to the development and implementation of metrology, or the measuring methodology, for flat-panel displays. Founded in 1992 and located in Boulder, Colorado, the lab's scientists have created a comprehensive and robust set of measurement methods for accurately evaluating the quality and accuracy of displays.

With the SilverPC up and running, (check the August and September issues for that), it comes time to talk about software. After all, you can't run a PC without software.
