A Brief Primer on Digital TV and What You Need to Know

Beginning with Luxembourg in 2006, followed then by ten other European countries, the advent of government mandated digital tv began. The United States decision to transition came soon after. The U. S. Required all television stations to move from analog to digital transmission effective June, 2006. 2011 will mark Asia's entry into the digital tv era with Japan coming on board.

The U. S. Congress' decision to mandate the switchover from analog to all-digital television was based primarily on two factors. First, the government's desire to free up precious broadcast bandwidth for those organizations concerned with public safety such as police and fire departments, and second, to provide viewers a better picture and sound experience. One other consequence of freed-up bandwidth is that some of it can be auctioned off by the government to companies which provide advanced wireless services.

To facilitate the conversion process the government addressed the need of those people who did not own a digital-ready television. It offered to those owners a coupon, worth up to forty dollars, which could be traded in for a digital converter box. Congress also stipulated that non-digital televisions could not be imported, nor could they be manufactured in the U. S. Retailers still selling analog television stock were required to prominently display at the point of sale a statement informing the customer that a converter box would be required for those sets.

The biggest difference in quality between an image generated by an analog tv signal and one generated by a digital tv signal centers around resolution. The level of detail and clarity of the picture the viewer sees is based on the number of pixels, arranged in a grid pattern, on the screen. Simply, the more pixels, or discrete points on the screen, the better the resolution will be. An analog generated grid usually tops out at 500 x 400 pixels. A digital image can create an image up to nearly ten times the number off pixels.

Multicasting is another advantage of digital television transmission. In an analog environment only one channel can be allocated to a chunk of bandwidth, whereas in a digital environment that same chunk can be divided into multiple channels. This provides television stations the opportunity to provide more programming to its viewers.

Interactive programming is another advantage of digital television. People subscribing to cable or satellite services will discover enhanced functionality. Example include movies-on-demand, text-messaging via the television's remote to live television shows, and VCR-type choices such as pause, slow motion and fast forward.

Today, consumers have four options when considering televisions. Analog TV's can still be used but require a converter box. A digital-ready set comes with its own converter but will usually lack in picture resolution. An HD-ready set may or may not include a converter which will generally offer good resolution. The most expensive option is the HDTV which will include a digital tuner and will have high resolution. Selecting which type of TV to go with is a matter of budget or other preferences.

With digital television viewers can realize new highs in picture quality and enhanced functionality. The developments of today represent only the beginning. As manufacturers seek out new technologies and competitive edges, the consumer can reasonably expect an even more compelling viewing experience.

Reasons To Get A Home Theater System

by Adrian Fletcher

Going to the movies is a great experience, especially on a rainy, gray day when you can suspend reality at the door of the movie theater and go into a fantasy world for a couple of hours. One thing that may be better though is to share your favorite movies at home. With developments in technology, our movie viewing experience can be comparable or better than the movies theaters. VCR's are a yesterday's news. With today's VCD and DVD players, watching movies on TV can be an awesome experience. But with Blu-Ray or HD-DVD technology and huge LCD screen TV's along with ear-busting surround sound you can take home movie watching to the next level.

Home theater systems have been increasing in popularity in the last few years and it's easy to understand why. With the new technology and the convenience of watching a movie at home, you can save money and still enjoy a good movie. An increasing number of households are having home theater systems installed in their homes that are comparable to the sound and features you would find in a real movie theater.

With the array of modern home theater systems, you don't need any special skills to select the parts that comprise a good home theater system. Even better, many home electronics retailers will offer different configurations ranging from separate components that you assemble on your own to complete home-theater-in-a-box setups.

So that you can really get the best experience and emulate the movies, you must have the right tools and equipment. The sound system is very important. A great surround-sound setup will allow you to hear the sound all around, and in a high quality.

You've most likely already heard of a surround sound system, in which the speakers on the right or left side produce sound depending upon where in the screen the action is taking place. For example, if the sound is heard from the left side of the screen, the sound produced by the left speaker will be louder than on the right. In order to do this, you must have at least four speakers and equipment to split up the surround sound signal and send it to the speakers.

You must consider the size of the movie screen as well as the resolution. So this means a TV of at least 27 inches when measured diagonally is the minimal requirement. If you can afford one a bigger one, 36 inches or larger is a better choice. Again this depends on the size of the room where the screen will be located but in many cases bigger is better (so they say !)

to this extent, you should consider the space in which you arrange the components. They can be arranged in many ways, but you should keep in mind how much you want to spend, and how much room you have. Ideally, a separate room with windows that can be darkened is a perfect option but not everyone has the space so often a compromise has to be reached. Experimenting with set ups is the best bet if this is the case.
