HDTV and Analog TV

What is HDTV and why is it so important?
is an entirely new system that will ultimately replace today’s existing analog "NTSC" television system. The term "HDTV" refers to a television system that can transmit, receive and display high-quality digital images.

Once the
DTV standard was set in 1996, the Federal government subsequently mandated a nationwide transition for the nation’s 1,600-plus television stations to move from analog to digital transmission. In order to facilitate this, the FCC allocated an additional channel to all broadcast TV stations. This second channel is dedicated for digital broadcasts and upon completion of the transition (the year 2006 or 85 percent household penetration, whichever occurs later), the original analog channel must be returned to the government. The FCC will eventually auction the analog channel spectrum.

What makes HDTV better than today’s television?
HDTV offers incredibly detailed, life-like picture quality with up to five times the sharpness of today’s television along with digital surround sound capability and a widescreen format.

Is my current TV obsolete?
No, analog televisions will continue to receive analog broadcasts at least through 2006, and probably longer. After that, consumers will be able to connect an inexpensive receiver to their existing TV to decode TV broadcast signals, just not in high-definition. Of course, current televisions will continue to work with cable, satellite, VCRs, DVD players, camcorders, video game consoles and other devices for many years.

What can I watch in HDTV?
The great news for consumers is that Hollywood is creating more and more digital programming at the highest levels of resolution and sound quality.
