More and more people are going high-def. Even in a bad economy, HDTV sales continue to be a bright spot for electronics retailers such as Best Buy and Circuit City, based on their recent financial reports. In the first quarter, worldwide sales of just LCD displays -- almost all of which are HDTVs -- increased 45 percent over the same period a year earlier, according to the NPD Group.A major reason is that U.S. consumers are switching to HDTVs in advance of the government-mandated switch to digital-TV broadcasts in February. But people also just like to keep up with the times.If you're new to HDTV, here's a guide to what kind of high-def programming is available for your high-tech viewing pleasure. To see specifically what's available in these categories in your area, visit the Web site Where Is HD? (www.whereishd.com).BroadcastThis is the easiest option because it's essentially free, especially if you already have a decent over-the-air antenna. Even if you don't, a relatively inexpensive set-top antenna, such as the Philips PHDTV1 for $25, will do the trick. (Go to www.antennaweb.org to gauge reception quality for your address.)CableThe high-def options broaden considerably with cable TV. Comcast (www.comcast.com), for instance, offers 39 high-def channels, including networks that offer high-def shows virtually around the clock, such as Animal Planet HD and ESPN HD. In addition, Comcast has more than 400 on-demand high-def programs that can be watched at the viewer's whim. Of course, all of this comes at a price. It ranges from $20 a month for a basic package that includes just the local HD channels to $115 a month for everything, including the required HD receiver. (Otherwise, leasing the set-top box costs $7 a month.) Prices and selection might vary depending on where you live, your cable operator and promotional offers.SatelliteSatellite-TV services offer even more high-def channels, but not the same on-demand options as cable. DirecTV (www.directv.com) wins the numbers game with 97 channels that offer high-def programming at least some of the time. High-def channels add $10 a month to DirecTV's monthly packages, which cost $30 to $82, depending on the number of channels you want. You also have to buy a DirecTV HD receiver, $100 to $200 depending on the model. The Dish Network (www.dishnetwork.com) has 72 high-def channels. A basic package with 45 high-def channels costs $30 a month, including equipment, while other programming packages -- $33 to $95 a month, depending on channel selection -- can have high-def channels added for an additional $10 to $20 a month.Blu-rayBlu-ray Discs are the high-def version of DVDs. More than 550 titles have been released to date. They offer the best high-def presentation in picture and sound. Players -- which also play standard DVDs -- start at about $300, although the best model, the PlayStation 3, starts at $400. Discs typically retail for $35 to $40 each, but retailers such as Wal-Mart, Best Buy and Amazon.com have had sales discounting titles to $15 to $20. If you don't want to buy the discs, the online rental service Netflix (www.netflix.com) offers Blu-ray titles at $17 a month for unlimited rentals of three discs at a time, its most popular plan. (Other plans cost $5 to $24 a month.)DVDStandard DVDs don't offer high-def resolution, but they can fake it. You just need an up-converting player, which includes Blu-ray models. Such players increase the lines of resolution to make a standard DVD look better on HDTVs. The result is a picture that isn't as good as Blu-ray but nevertheless will please many viewers, especially those who already have a sizable DVD collection. The only catch is that you must connect the player to your setup using an HDMI cable. Oppo (www.oppodigital.com) makes award-winning up-converting players starting at $169. But reliable models can be found for less than $50 through bargain sites such as Dealnews (www.dealnews.com).OnlineStreaming high-def content from the Internet is still relatively new and problematic, but it is largely free. You'll need a computer, an adapter and other cables to get things going, or a special interface box such as the soon-to-be-released HP MediaSmart Connect ($349). A recent article at Dealnews explains how to do it by someone who gave up cable TV for a month to try online streaming exclusively. His conclusion: "Despite its great strides ... Internet TV just isn't ready for prime time."(Contact Randy A. Salas at rasalas(at)startribune.com.)(Distributed by Scripps Howard News Service, www.scrippsnews.com.)

Think About Up-Grading Your Off-Air Antenna For Better Reception
You're right about recommending viewers to try their current over-the-air antenna before buying a new one. But many of the TV antenna designs in use now and on the market today, such as the outdoor Yagi (on many chimneys) and rabbit ears, have technology roots going back 30 years or more.
The transition is coming, whether Off-Air only viewers are informed or not. To add to the dilemma, much has been written about the need for converter boxes for viewers with older TV sets, but completely ignore where reception starts at home, at the antenna.
And many articles and blog post have said an antenna is an antenna, they’re all the same. Not true. These people think of antennas as low-tech devices, but there is more behind some of the newer antenna designs than just bent metal and plastic.
The switch to free digital broadcasts has brought consumers back to Off-Air reception and the increasing sales are providing the motivation and investments necessary to develop new models and new technology.
The fact that most designs on the market now were developed prior to the advent of much of the computer technology, software and algorithms in common use today has left open numerous avenues to improve upon tried and true designs and develop new ones.
Additionally, recent regulations and standards are opening new doors for antenna engineers to develop smaller antennas with greatly improved performance and aesthetics.
The correct antenna, installed and aimed properly, unimpeded by obstacles such as building, hills, trees, etc. will receive desired local stations in range it’s aimed at. And the new antennas, working with the newer generation ATSC chips will mitigate multi-path (bounced signals). Multi-path, multiple signals, reaching the antenna out of phase, can confuse the ATSC (Digital) chip set in the converter box or digital TV tuners.
If the signal reaching the front of the antenna is not 2 to 3 times stronger than a bounced signal from the same station reaching the back of the antenna, the ATSC chip doesn’t know which signal to use, so it just keeps searching. The answer is to up-grade to a new digital indoor antenna (outdoor is much better if you can install one), tuned to receive digital signals and help reject Multi-path signals for better reception.
The more powerful the antenna, the further from the towers your antenna can be located, up to 70 miles or more. Signals bounce off many things, even walls inside the reception room, in the case of an indoor antenna. But sometimes a bounced signal can be stronger than trying to receive the signal aimed at the towers in metro/urban locations. If you’re going with a new indoor antenna, try several different locations and directions in the room.
And Off-air antennas will receive several free HD programs, almost completely uncompressed, not available from cable or satellite and multi-cast programming adding several additional local off-air programs. Some viewers may even be able to receive out-of-town channels, carrying blacked out sports programs or network broadcasts not available in their home town. As an added benefit, an OTA antenna provides reception for second sets in homes not wired for whole-house signal distribution.
While cable and satellite program providers will continue to serve the great majority of homes as the primary signal source, missing HD local reception, compression issues, higher costs, billing add-ons, service outages, contact difficulties, in-home service waits and no shows have left many of these subscribers looking to OTA antennas as a good alternative.
To check out free OTA options, viewers can go to antennapoint.com to easily locate the broadcast stations within range, aiming directions and other OTA helpful information.
Depending on their level of desire to receive all the free Off-Air signals available to them, considering the investment in TV entertainment already made by many viewers, shouldn’t they consider up-grading to a new Digital Off-Air Antennas, designed and tuned to receive post transition digital broadcast signals.
If they buy a new antenna, they should buy one from someone who will refund their purchase price, no questions asked, until they find the right antenna for their location.
