HDTV stands for "High Definition Television."
HDTV is a digital signal that delivers clearer, sharper and more vibrant images. Traditional, NTSC analog signals provide 240 to 480 lines of resolution while HDTV signals generate substantially higher resolution (720 and 1080 lines of resolution) resulting in sharper images.
High-definition is in your future
In order to find additional space for emergency communications and advanced services, Congress mandated TV broadcasting to move towards more modern and efficient "digital" techniques as of February 17, 2009. After that date, your local television broadcasters will be making only "DTV" or "digital television" broadcasts. DTV signals are sent from local transmitters to homes by modern digital techniques, as opposed to older analog signals. If you have TVs in your house that are not hooked up to your cable or satellite service, and rely on an antenna to receive conventional broadcasts, you will need to make alternative arrangements to keep watching these TVs.
Finding HDTV programming & content
Most cable and satellite programmers offer HDTV packages. If you don't have a cable or satellite package, HD programming is available for free over the air – if you have an integrated HDTV, or a HD-ready TV plus a tuner, and an antenna. Thousands of hours of HDTV programming are available weekly, including football, auto racing, primetime programming, movies, documentaries and more.
HD-ready TVs vs. integrated HDTVs
An Integrated HDTV has a tuner/decoder built into the TV, and can receive over-the-air broadcasts through an antenna. HD-Ready TVs typically don't have a built-in tuner, and an external tuner must be purchased to receive over-the-air broadcasts through an antenna. Whether or not your TV has a built-in tuner, you may still need additional equipment from your cable or satellite company to receive more than locally broadcast channels.
1080p technology vs. 720p technology
The "p," or "progressive scan," means that the entire image seen on the television screen is repainted at once, rather than line by line, which is typical in older interlace technologies. This results in a higher-resolution picture, increased image detail, and smoother action.
DLP 1080p is the next generation of HDTV technology, offering 2 million pixels on screen. That is twice theresolution of 720p. With a DLP 1080p HDTV, you can experience the best that HDTV has to offer today and be ready to enjoy all of the 1920 x 1080p sports and entertainment content that's on the horizon.
Game consoles and DVDs will increasingly move toward 1920 x 1080p resolution allowing highly realistic action and environments. Film converted to 1080p format for home theater delivers the image quality the director envisioned. Major TV networks are already broadcasting in 1920 x 1080i format and future broadcasts in 1080p will be a natural evolution in digital TV. DLP 1080p HDTVs are ready to accept all the current DTV content offerings, as well as whatever additional 1080 content lies ahead.
