It may be time to start asking the question that's asked of all pastimes with hobbyist roots when their popularity surges: Is home theater a permanent cultural phenomenon or just another fad destined to burn out before its time? Recent evidence certainly shades the former. DVD-Video has been the catalyst for an unprecedented boom in the popularity of home theater and should probably be credited with completing home theater's undeniable transition from novelty act to mainstream entertainment that began with Dolby Surround and the first inexpensive multichannel speaker system. But is home theater a cultural phenomenon the way that the computer is a cultural phenomenon? Do a majority of Americans actively seek to make it a part of their lives day in and day out? Not yet—but home theater's high-water mark is still to come.

Anyone who's looked at the back of a new, high-end TV or receiver and gazed upon row after row of ports knows that there just might be too many ways to connect other devices. Believe it or not, more inputs are going to become commonplace in the next few years (a number of high-end TVs already have seven video inputs in four different formats). Whether you fall into the category of those who are just discovering the merits of S-video or those who like to argue the merits of their projector's five-wire RGB inputs, the number and type of connections, ports, and inputs has exploded in the last decade, and it isn't going to get any simpler in the next few years.

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.

You must allow me a bit of hyperbole for the sake of a powerful opening statement (which, as I assume they say in journalism school, is important). The truth is, the CD is about as dead as the analog television, which means it's alive and kicking just as it has always been. Still, the writing is on the wall for both formats. While the CD can at least take consolation in the fact that it doesn't have government mandates guaranteeing its demise, the future of audio has most definitely arrived (as with television) in the form of high-resolution. Let's not forget multichannel, either. While the hard-core music lovers are salivating over the potential of high-resolution, most are well aware that popular acceptance in America usually requires the new and different to be as big and flashy as possible. On many systems, the multichannel format is undoubtedly going to represent a more-noticeable change in the way people listen to music.

If you're thinking of buying a DVD player, the number of features most players offer might overwhelm you. Sure, you know the basics: DVD is the hottest thing since the first time man invented something round. It consists of a disc the size of an audio CD but with 10 to 15 times more storage capacity. The disc has enough room to store a full-length motion picture with a digital picture that's better than that of laserdisc or satellite broadcasts. A progressive-scan DVD player connected to a widescreen TV can even approach the quality of high-definition television. The digital audio can include up to five full-range, discrete (meaning separate) channels with one LFE, or low-frequency-effects (aka the .1), channel for impact. The best part is that DVD players and movies should be compatible with your current system, no matter how archaic it is. You can buy a DVD player now and almost certainly enjoy the benefits right away, and you can upgrade various parts of your system and glean even more performance from the DVD software that you'll undoubtedly start collecting. What you really want to know, though, is what features to look for in your first/next DVD-player purchase. As usual, we're here to explain them to you. We've also included a couple of tips on how you can take your DVD/home theater experience to the next level.
