High Definition Television
HDTV, which stands for high definition television, first appeared in 1998. Manufacturers claim that high definition television provides an extraordinary viewing experience. Consumers, however, have to contend with the price. The question at the back of almost everyone's mind is, is it worth it? HDTV's prices range from $1000 to $5000. That's about 10 times the price of the regular television sets.
Critics (the positive ones) say high definition television is the future of television much like how we kept the black and white TV in the garage when the colored screens came, or how VHS replaced BETAMAX, and how CDs took the place of VHS, and so forth.
High definition televisions are digital. They can receive signals from analog, as well as progressive-scanning from DVDs. To date, there are three known formats of HDTV: 720p, 1080p and 1080i. These formats differ in the resolutions of their screens. The resolution of 720p is 1,280x720. It produces high definition images that display progressively. Pictures look smooth with this resolution since the lines go on display simultaneously.
The second format, 1080p, displays 1,920 x 1,080 resolutions. The high pixel resolution and continued progressive-scanning results to smoother and highly-detailed images. This format is known as the ultimate standard in high-definition televisions.
The third format, meanwhile, display interlaced but high-definition images with 1,920 x 1,080 resolution. The odd lines are followed by the even lines of pictures. This format is not compatible with DVDs that perform progressive scanning. Critics, additionally, claim that actions are not well emphasized in this format and it is best suited for documentaries as well as wildlife videos. Several stores sell HDTV-ready televisions. They have high definition capabilities but still require high definition tuners in order to produce HD signals.
