HDTV FAQ

By Tony Brown

What are DTV and HDTV?
DTV is Digital Television. It is any broadcast that uses a digital signal. HDTV is High Definition Television. This is a digital broadcast offering the highest quality picture and sound available. SDTV is a digitally produced broadcast that delivers better resolution than analog TV, but lower resolution than HDTV. Analog TV is what you have been watching for years.

How can I see Your TV20's Digital Signal (KBWB-DT)?
Like traditional TV, our digital signal is a free over-the-air broadcast that you can receive via a UHF antenna. In addition you will need a digital tuner, which can be purchased as a stand-alone box or built into a digital television. If your receiver does not automatically find our signal, it is on digital channel 19. Depending on your location, you may need a UHF antenna outside or in your attic.

What shows are in HDTV?
Many network programs and movies are in full HDTV. Look for programs marked HD on our program grid.

What are the benefits of DTV?
Wider Format:
HDTV screens are about one-third wider than existing TV screens. They have similar dimensions to movie screens. HDTV screens closely match the peripheral vision range of the human eye, making it more natural to watch.

Higher Quality Picture and Sound:
HDTV uses the same amount of bandwidth (six megahertz) as used in the current analog system, but HDTV can transmit more than six times the information as the analog system. This translates to higher quality in picture and sound.

Higher Resolution:
SDTV television pictures are made up of 525 lines that are scanned horizontally. HDTV pictures are created by scanning 1,080 lines. Adding twice the amount of lines multiplies the amount of pixels (the small dots that create the picture). Current sets have about 300,000 pixels, while the HDTV screen is composed of more than 2 million pixels. Having more pixels on your screen will also improve the sharpness of your pictures, allowing you to read on your television screen small text commonly found on computers.

True Surround Sound:
Complimenting the lifelike pictures are 5.1 channels of CD-quality digital audio. Current stereo TV sets offer only two channels of audio. HDTV delivers true surround sound: front speakers on the right, center and left, along with two back speakers and a sub-woofer.

Strong Signals Always:
The days of static and ghosts on your TV set are over. The digital signal will also strengthen signal quality, meaning the signal will be just as brilliantly clear and sharp up to 65 miles away if there are no obstructions between you and the tower and a quality antenna and preamp are used. If you can receive our digital signal, you will always get studio-quality video and audio.

Interactive Possibilities:
Thanks to digital broadcasting, we can also broadcast data (datacasting), which will revolutionize the way you communicate, entertain yourself and live your life. We will be able to marry the convenience of television with the power and freedom of the Internet. Datacasting will make truly interactive TV possible, empowering the viewer to make television-viewing an incredible experience.

More Than One Channel (Multicasting):
We can also squeeze in more than one "channel" of television or data into our digital TV channel. In special circumstances, we can choose to send a channel of high-definition TV, up to two channels of standard-definition TV (SDTV) and a channel of data at the same time.

Will my current TV become obsolete?
Originally, Congress set the year 2006 as the final date to turn off the existing analog television systems. However, that date was delayed until more than 85 percent of the people had access to digital television signals. Since digital television is now prevalent across the country, TV stations will be required to turn off the analog signal on February 17, 2009 at Midnight. Therefore, if you receive your signal with an antenna, you will need a DTV converter box to continue receiving TV programming. However, you will not be able to enjoy the crisp high-definition picture associated with HDTV or High Definition Television. Your analog sets can always be used with your existing video equipment, like VCRs, DVD players and video games.
