Why are TV broadcasts switching to high definition?
The short answer is that high-definition TV provides picture and sound quality most people have never seen or heard before. The more specific answer is that HDTV shows you pictures that are unbelievable, bordering on three-dimensional. The sound is not only as good as a CD, with the right kind of equipment you’ll be able to hear your favorite TV shows and movies in one of the most sophisticated types of surround sound available–Dolby Digital.
