Editor’s Note: The following article is an excerpt from Take Control of Digital TV, a $10 electronic book available for download from TidBits Electronic Publishing. The 77-page ebook helps readers work through the buzzwords and acronyms to pick the best digital TV, position and configure it for optimal viewing, and find HDTV programming.
The long-hyped digital convergence of home media is finally under way. Digital TV is the key to bringing this unification to your own home. In this excerpt, I briefly explain how to bring your TV-based and computer-based systems together in perfect harmony.
Consider an A/V Receiver
Instead of attaching all your audio and video inputs to the different connectors on your DTV set, or daisy-chaining them in a potentially signal-degrading sequence from one machine to another, you can buy an A/V receiver to act as the hub of your home entertainment network. All your sources (DVD, VCR, cable or satellite box, CD player) go into the A/V receiver and back out to your DTV monitor and speakers. Almost all HTIB packages include an A/V receiver. Some A/V receivers include ambience processing , a bit of digital trickery to provide fake surround effects to music CDs.
Here are some pros and cons to using an A/V receiver:
• Pros: Stronger signals, cleaner connections, fewer remote controls, and consistent decoding of surround sound. Some home-theater experts claim you shouldn’t attempt to hook up surround speakers without an A/V receiver to route signals to them, even if your DTV set or DVD player has separate surround-speaker outlets.
• Cons: Less flexibility. It’s an extra expense ($200-$1,000 for some current models) you might not absolutely need, particularly if you’re only using two speakers.
Consider a DVD Player
Until either Blu-ray or HD-DVD players and discs find more consumer acceptance, today’s DVDs are the best tangible source of video you can get. The tens of thousands of DVD titles released in the past nine years (yes, it’s only been that long) will still play on your DTV gear, especially in widescreen and surround sound, and will look crisper and more detailed than they ever did on an analog TV.
Look for the following features in current players:
Some DTV sets contain their own deinterlacing firmware, which could do a better or worse job than the deinterlacing in a DVD player. DVD players are so inexpensive these days that you might as well buy a progressive-scan model, then experiment with the results with the progressive-scan feature turned on and then off.
If your regular viewing fare is limited to major Hollywood features and TV-series compilations, a single-region player is good enough. But if your tastes veer toward Japanese anime or Latin American drama, look for a player that is, or can be easily adjusted to become, region-free.
For more information about DVD regions, check out Home Theater Info and DVD Demystified. Sources of region-free players include Region Free DVD Player, Code Free DVD, and HKFlix.com. For discussions about which DVD players can be easily modified for region-free playback, see VideoHelp.com. (If you alter a DVD player for region-free playback, you might void its warranty.)
So, to play discs sold anywhere in the world, you simply need a player that translates the data from PAL discs into NTSC output. Fortunately, several players (even some that aren’t region-free) can do this. Others will directly output PAL data, which many DTV receivers can convert internally. Check the manufacturers’ specs and online forums to find one.
Consider a DVD Recorder
Most home computers these days have built-in DVD drives. Some of them can record discs, some can only play them, and some can record to regular CDs but not to DVDs. If your computer doesn’t include a DVD recorder, get an external one. You can also get a DVD recorder that’s made to attach to a TV, but a DVD recorder that attaches to a computer is far more useful.
Everyone reading this book should have a DVD recorder—not only to burn backups of your movies, but also—in some cases—to burn regular backups of your computer data. As even mid-price laptops now have hard drives bearing 30 GB or more, backing those gigs up to CDs has become too tedious for many users to perform as regularly as they should. A DVD recorder can record those 30 GB on as few as seven discs, each of which can get burned in as little as seven minutes depending on the disc and recorder used; the older CD-R technology needs as many as 40 discs to hold the same data.
DVD recorders come in three main flavors—DVD-R and DVD+R (two rival recording systems), and DVD±R (which can record and play both systems). DVD-R machines can’t record to DVD+R blank discs and vice versa; a DVD±R machine can record to both disc types.
The software supplied with your DVD recorder probably won’t work with copy-protected discs. You’ll need a “ripping” program, to transfer the data from a protected DVD into an unprotected version you can then burn to a DVD-R. Ripping software for Mac OS and Windows can be found via a search engine.
Why you should back up your DVDs: I’m opposed to the commercial piracy of movies. But I’m strongly in favor of the right of consumers to make backup copies of the DVDs they own. These discs are, despite advances in manufacturing, still subject to breaking, scratching, and simple overuse. You not only should have the legal right to preserve your investment by making backup discs, you should do so.
Consider a Digital Video Recorder
Digital video recorders (often abbreviated as DVRs; also known as personal video recorders, or PVRs) are the main way to record HDTV fare, and the best way to time shift DTV viewing, so you can watch your favorite shows when you want to, not when they are broadcast.
TiVo may be the first famous DVR brand, but it’s not the only one. Its competitors now include many cable and satellite providers, who increasingly offer DVRs built into their set-top boxes. If you use a cable or satellite company’s DVR, it’s an extra few bucks on your monthly bill. If you use TiVo or a similar separate product, you have to buy the box and also pay a monthly fee to connect to its electronic program guide, or EPG.
DVRs are essentially special computers. They record to, and play back from, internal hard drives. Some cable company models store channel and schedule information in RAM; if one of these DVRs loses power, its program information is lost and has to be automatically redownloaded, but the shows recorded to its hard drive remain.
A series of point-and-clicks on your remote control guide you through the EPG’s constantly updated menu of upcoming shows, allowing you to quickly set up future recordings days in advance.
The advantages of using a DVR instead of a videocassette recorder (VCR) to record and replay TV shows include having full digital quality (including HDTV on some models) and enjoying easier programming, recording, and playback. However, a DVR’s internal hard drive has a finite amount of space, and it takes know-how and equipment to move shows from a DVR to anything except old-fashioned VHS tapes.
Consider a D-VHS Recorder
One other way to record DTV and HDTV material, D-VHS, is a digital variant on the old-fashioned VHS videocassette. (Both systems were originally developed by JVC.) It can record up to 4 hours of HDTV on one tape cassette, or 24 hours of standard-definition video.
Consumer D-VHS recorders are rare, as are prerecorded D-VHS movies. (D-VHS tapes won’t play on standard VHS machines, but regular VHS tapes will play on D-VHS machines.) You can buy D-VHS machines, and blank and prerecorded tapes from DVHSmovie.com.
