HDTV Q A

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.

How can I see KSEE-DT? Like traditional TV, our digital signal is a free over-the-air broadcast that you can receive via a UHF antenna. You can receive both KSEE-DT and KSEE Weather Plus this way.

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 38. Depending on your location, you may need a UHF antenna outside or in your attic.

Advice on what kind of antenna you need at your home can be found on KSEE-DT is also available on Comcast digital cable channel 904. KSEE Weather Plus is also available on Comcast digital channel 195. What shows are on KSEE-DT?

All shows broadcast on KSEE are also simulcast on KSEE-DT. Some are in full HDTV, while others are up-converted. We also broadcast NBC Weather Plus on our secondary channel, 24.

2 (see below). What are the benefits of DTV? 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. 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. 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.

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. 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. 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. 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? The FCC has set the date of February 17th, 2009, as the date for all TV stations in the U.S.

to cease their analog broadcasts. As of that date you will be able to receive our digital broadcasts in one of three ways: 1. Over the air on a television with a built-in digital tuner The FCC has mandated that all new TVs, VCRs, and DVRs include a digital tuner by March 1, 2007 2.

Over the air utilizing a stand-alone digital tuner or converter box attached to an older television This option will not allow you to receive the full benefit of HDTV, but you will be able to continue to use your existing television 3. Via a cable or satellite service that is re-broadcasting our signal Check with your provider for availability. Your provider may charge an additional fee for HDTV signals.

Your analog television can always be used with your existing video equipment, like VCRs, DVD players and video games.
