The U. S. Was not the first to mandate this transmission nor will it be the last. Luxembourg and ten other European countries have already implemented the digital transition, while Japan will go all digital in 2011.<br /> <br /> 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.<br /> <br /> The conversion process ushered in additional legislation. Starting March 1, 2007, consumers had to be informed by stores selling analog only sets that a digital conversion box was required. This had to be done at the point of sale and had to be clearly displayed. Moreover, no longer were analog television sets allowed to be imported into the U. S., and any television manufactured in the U. S. Had to be digital-ready. For those individuals who owned only analog televisions, the government authorized vouchers which could be exchanged for a digital converter valued up to $40.00.<br /> <br /> A television's resolution, or quality of image, is defined by its detail and clarity. It is based on the number of pixels displayed. Pixels are dots on the screen arranged along the horizontal and vertical. The more pixels arranged on the screen the better the resolution of the image. In an analog environment the maximum array of pixels is typically around 500 by 400. A digitally created image is comprised of up to ten times the number of pixels.<br /> <br /> 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.<br /> <br /> Digital tv also facilitates interactive programming. Cable and satellite subscribers can take advantage of functions such as movies-on-demand, and VCR-like capabilities such as pause or fast forward when watching programs. Even sending a mobile text message to a live television broadcast via the television's remote control is possible.<br /> <br /> In today's digital television environment there are now four types of television available to the consumer. Analog televisions(which require converter boxes), digital-ready sets which have a digital converter(or tuner) but suffer from low resolution, HDTV-ready units which provide high resolution but may not have a converter, and an integrated HDTV set which provides high resolution and a tuner. Budget and personal preference play heavily into which choice is made.<br /> <br /> 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.</p> <br /><br /><b>Author Resource:-></b> Looking for the <a href=http://www.cable-internet-packages.com/specials/best-cable-internet-deals/>Best Cable Internet Deals</a>, then visit our site on how to choose the best <a href=http://www.cable-internet-packages.com/>Cable Internet Packages</a> for your needs.<br /><br /><b>Article From</b> <a href='http://www.articleonlinedirectory.com/'>Article Directory Online : Free Online Article Submission - Articleonlinedirectory</a><br /></body></html>
