At this year's CEDIA Expo, two technologies ruled the day: A/V servers and Internet Protocol (IP). It's safe to say that convergence really has invaded every part of the home theater arena. If your eyes tend to gloss over when your computer-savvy friends toss around words like IP, network, and Ethernet, I've got some bad news for you: You can run, but you can't hide. First, the computers took over our offices; now they're invading our entertainment space. Someday, they'll kill us all—but hey, we'll probably be gone by then, so let's talk about how IP can enhance your home theater experience.

Several years ago, I attended a David Copperfield show in Las Vegas and was invited onstage to be a part of one of his magic tricks. Sadly, it wasn't anything exciting, like being levitated or sawed in half. He just guessed my phone number after I wrote it down on a piece of paper and quickly burned up the paper. (No, he never did call.) Still, it was fascinating to try and figure out how he did that trick and the other more-impressive ones I witnessed that evening.

As HDTV broadens its horizons, the role of the standalone HDTV tuner has diminished but certainly not disappeared. Sure, this year, the FCC ordered TV manufacturers to begin incorporating internal ATSC tuners into new 36-inch-or-larger TVs that have an NTSC tuner, but what if you've built your home theater around a high-end projector or a flat panel with no internal tuners? Sure, the satellite and cable companies are offering more HDTV content by the minute and adding DVRs to their new HD set-top boxes, but that doesn't help the person who can't have a satellite dish, isn't getting much (if any) HDTV from their cable company, or doesn't want to pay a monthly fee to watch and record HDTV.

It baffles me that the digital video recorder hasn't caught on with mainstream consumers. Everyone I know who's spent 10 minutes with one of these gems is instantly addicted. It has a VCR's functionality, a digital cable box's user-friendliness, and a computer's brain. As far as I can tell, only two things are preventing the DVR from making it big: price and permanent storage.
