ResearchUnderstanding DTV
What exactly is DTV? This is a fair question, with all the acronyms out there it can be difficult to keep them all straight let alone understand the different technologies that are actually behind all of these different things! DTV is the acronym and the commonly used term for digital television. Digital television is becoming more and more common and has had growing support over the last few years. Many television programs are already shot and displayed digitally, and when you watch them on an older analog television they look terrible! Because of the poor display quality of digital signals on an analog television, digital television or DTV will become the standard worldwide.
How It Works
Digital television is simply the most modern way of broadcasting. DTV is truly changing the television viewing experience for the better, though there is always some resistance to change. With digital television images as well as sounds are captured or taken in using digital technologies. It is this digital technology that brings us the high quality picture that is always associated with DTV. The digital technology can deliver a movie quality experience as well as multicasting and interactive capabilities that are more impressive than ever before.
Why You Want It
Digital television isn’t a mediocre technology that will come and then go as fast as it arrived. This truly is the way television will be done in the future. You want digital television because it provides you with better quality, more choices in what you watch and when you watch it, and simply more control over your television viewing experience. If you compare digital television with the television choices of ten years ago you will see how far television has come and why you want and even need it now, to a certain extent. Digital television allows you to create your unique television viewing experience.
Differences In Digital Television
While digital television is the future of all television, there are varying levels of DTV already in use. Understanding the type of digital television you may be dealing with will help you determine what type of television you need now and whether it will work for you in the future.
First, there is standard definition TV, also known as SDTV. SDTV is a basic level of quality digital display and resolution for both analog and digital displays. The transmission or broadcast of SDTV can be in either the 4:3 aspect ratio or the 16:9 widescreen format.
Next there is enhanced definition TV, or EDTV. EDTV is actually a set up from analog television and is broadcast in either 16:9 or 4:3 formats. EDTV is a better display quality than SDTV but is not as good as the popular and crisp and clear HDTV.
Thirdly there is HDTV or high definition TV. High definition is in widescreen format and provides the best picture and highest resolution of all the digital broadcast formats currently available. When HDTV is coupled with state of the art sound systems the overall experience is unlike any other as the HDTV sets new standards for both sound and picture quality.
Digital television simply makes sense, as we spend so much money on televisions and cable and such, it might as well look as good as possible. It’s thought that by 2010 that almost all television will be broadcast digitally with the change taking place slowly. For those that do not upgrade their analog televisions, their viewing experience will be compromised, but they will continue to work for a time. Over time it is thought that everything from cable, satellite, video games, VCR’s, and even DVD players will only work with newer televisions. This means that the analog television is quickly becoming obsolete, and this is driving more and more people to upgrade to a new television now instead of later. There is no doubt that the future of television is in the digital capabilities just getting started today.
