High Definition Television (HDTV) is a new way of broadcasting television signals in a digital, rather than analog, manner. In order to view HDTV programs, you must own a television that is HDTV compatible. The television will either come equipped with an HDTV tuner or you will have to purchase one separately.
HDTV is valued because of its crystal-clear images and its high quality sound output. HDTV was originally designed because studies showed that people who sat up close in a movie theater and were able to see the images displayed in a wide, close format enjoyed the movies more and felt more immersed in the show.
HDTV has copied that premise. It provides pictures that are sent in a 16 by 9 aspect ratio, compared to the 4 by 3 aspect ratio that regular analog TVs have. Another important aspect of HDTV is the picture resolution. An HDTV will provide you with at least double the picture resolution that a regular TV offers. This is why the picture looks so crisp. Also, HDTVs provide a higher quality sound than a regular TV.
HDTV works in a somewhat similar manner to a digital camera. It takes an image and transforms it into a digital signal. The digital signal is actually made up of a combination of 1’s and 0’s. This digital signal is then transmitted to the television through the broadcast station. An HDTV works like an analog TV in the sense that it receives the signal from the broadcast source. However, an HDTV is made to pick up digital signals, not analog. There is a definite advantage because digital signals stay crisp and strong no matter how far they travel.
If you are looking for a television that will provide you with a very clear picture and excellent sound quality, you might want to consider purchasing a HDTV. The number of television shows being broadcast in HD increases all the time.
