Transition to New TV Technology Has Perils

December 21st, 2009

There are a lot of advantages to digital TV. That’s why the US Congress has mandated that all over the air TV signals will be in digital TV format by February 17, 2009. At that time, analog over the air TV signals will be discontinued and only digital TV signals will remain. This will also free up a lot of telecommunications bandwidth for other telecommunications applications like emergency services communication and widespread wireless networks.

There are some major problems with this switch to the digital TV format. For one thing, many people don’t know exactly what digital TV is. Worse yet, even fewer people know that the switch to digital TV for over the air broadcasts is taking place.

There are many misconceptions about digital TV. Perhaps the most major one is that digital TV is the same thing as high definition TV (which is known as HDTV for short). In reality, while HDTV is digital, not all digital TV is high def. Digital TV simply means that the TV signal is transmitted in a digital format like how video is encoded on a DVD. This results in a much clearer picture that’s more resistant to interference. It also takes up less bandwidth, thereby increasing the number of channels that can be transmitted using any given number of frequencies.

Of course, people don’t need to know the technical aspects of digital TV in order to enjoy it. The much bigger problem with this planned transition is that most people don’t know that the transition is going to happen. While there are only about twenty two million Americans who rely on over the air transmission for their TV programming, less than half are aware that the transition is imminent or even what it will mean to them. Basically, anyone who’s been watching over the air TV in analog format and who doesn’t have a digital tuner built into their TV set or a special converter box to change the digital TV signals into analog signals before feeding them into the TV set, won’t be able to watch TV on February 17, 2009.

The prospect of people all over the country being taken by surprise when they wake up that morning and are suddenly unable to watch TV has led to reactions from analysts ranging from “Who cares?” to “The public will be outraged with us. ” to “There will be riots in the streets and people will be looting consumer electronics stores to get digital TV’s!” While the last reaction seems pretty extreme, if things keep going the way they have been leading up to the transition, a lot of people could be very upset and justifiably so. So far, the government has set aside less than two million dollars to subsidize the purchase of converter boxes for analog TV owners and only five million dollars to educate the public about the transition. TV manufacturers- who have known about this for years- have continued selling analog-only TV sets and only recently bothered putting warnings on them stating that they will be obsolete when the transition comes. TV stations that broadcast over the air and are in the situation of being in the best position to educate the public- and have the most to lose by not educating the public- are waiting for the government to do something about the situation. All of this while the deadline approaches and many TV viewers remain blissfully ignorant that anything will change at all.

5 Reasons Why A DLP HDTV Should Be In Your Future

September 27th, 2009

Television technology has been essentially static for several decades until just recently. The old CRT tube TVs reigned supreme for years simply because the broadcasting technology could not allow for anything better to come along. Even if you had sophisticated monitors and sound systems, they wouldn’t be of much use because the TV signal couldn’t transmit enough information to reaaly make use of them.

But HDTV has changed the whole TV viewing horizon, and there is no better time to make the switch from analog to HDTV. Here are five reasons why a HDTV DLP should be in your future soon:

1. The FCC has passed a law that requires all TV stations to broadcast in digital format by the end of 2006, and that means that almost all broadcasting will be done in HDTV by sometime in 2007. After that, if you want to be able to receive over the air TV signals on your old analog TV set, you will need a digital to analog converter box to do that. So why not be ready for that change by getting the necessary equipment in place now as prices have fallen dramatically lately?

2. HDTV not only means improved picture resolution, but it also makes use of the widescreen format that is more compatible with the way that movies are actually filmed, so you get to see the whole screen image instead of having some of it cut off by an incompatible screen ratio.

3. HDTV also enhances the sound capabilities as it even supports Dolby 5.1 surround sound that is used by many movie theaters today. This makes true home theater sound easy to achieve.

4. DLP TVs employ newer screen technology to be able to display much brighter, sharper, and color dense images than has ever been possible before. They run cool, use relatively little electricity, and can come in very large screen sizes if you wish.

5. DLP TVs also are thin, making them a perfect choice for those with limited space. Because of their thin configuration they can be placed closer to the wall or even mounted right on it, allowing more viewing area in the room that would not have been possible with older bulky TVs.

All in all, HDTV and DLP TVs are a great choice for the ultimate in home television viewing. If you haven’t actually seen a demonstration of a DLP HDTV, why not visit a local electronics retailer and ask to see it for yourself? Many people just don’t understand what all the fuss is about until they actually see it in person, but once you do, you will no doubt come away very impressed. Just be sure that you don’t let this wave of the future in home entertainment pass you by!
