On this page, we'll answer some frequently asked questions about this exciting new technology.

What is Digital Television?
Digital television is new technology television, yielding clearer pictures, better sound, more network channels, and more viewing excitement that traditional analog television. Digital TV offers a picture free of "ghosts," "snow" or interference. The crisper, sharper image is due to the increased number of pixels the digital signal puts on the screen - the higher the number, the sharper the picture - and High-definition Television ( HDTV) has the highest resolution available. Furthermore, Digital TV provides 5.1 channels of Dolby Digital CD quality surround sound, adding to the ultimate home theater experience Digital TV also enables broadcasters to multicast, delivering up to three or more simultaneous programs in a Standard-Definition (SDTV) format.

What is the coverage area for KWWL-DT?
KWWL-DT, on digital Channel 7.1, and 7.2 began operating at full power in early June of 04. When at full power the KWWL-DT coverage area will equal the current analog signal now broadcast on KWWL-TV. The transmitter used by KWWL-DT is manufactured by Harris Corporation in Quincy, Illinois.

Why is Digital TV better than "regular" analog TV?
DTV brings viewers five times the picture resolution and clarity of analog TV, making viewers feel like they are right in the middle of the action on their screens. Digital TV uses binary code, the same system of ones and zeroes that run on computers and digital is like switching from cassette tape to Compact Disc or from a VHS tape to a DVD - the pictures are clearer and sound is improved, giving viewers the opportunity to experience their favorite programs on a whole new level. What's more, with a 16:9 aspect ratio compared to today's 4:3 aspect ratio of analog television, Digital TV lets viewers see much wider images.

What about my existing analog TV?
Until the total conversion to Digital TV is made, broadcasters will generally simulcast the same programs on two different channels - one in a digital format and one in analog. Viewers with analog sets will be able to convert a digital signal to an analog signal by hooking up a digital tuner decoder box to their sets; they will not be able to experience the crystal clear pictures and sound quality that a DTV set provides, nor will they experience the advantages of datacasting or interactive television.

What are the different signals that viewers will see on a Digital TV?
Digital TV gives broadcasters the flexibility to bring viewers programming on different types of digital signals - ranging from high definition. Digital TV signals have better resolution than analog TV, which has been in use for more than 50 years. High-definition digital broadcasting is much clearer and sharper than digital cable.

With Digital TV, broadcasters can send various signals to consumers, including:
* High-Definition Television ( HDTV) - An HDTV signal allows a broadcaster to transmit a wide screen picture with many times more detail than is contained in current analog TV pictures. HDTV brings viewers programming so crisp and so clear, it produces an image as sharp as reality. In addition, HDTV offers unsurpassed audio quality.

* Standard-Definition Television (SDTV) - A SDTV signal is another type of signal that viewers experience through DTV. While a SDTV signal also has higher-quality video and audio than an analog signal, SDTV is particularly remarkable because it can bring viewers multiple channels of free over-the-air programming from the same station. In effect, one digital television signal has the ability to carry either a program broadcast in HDTV, and in some cases one additional standard definition signal, or several programs broadcast simultaneously in standard definition television on different channels.

What should consumers look for when shopping for a new TV set today?
When shopping for a new TV set, consumers today have choices...

1. An integrated Digital TV set - This option allows viewers to receive analog and digital signals. An integrated set can project high-definition (HD), enhanced-definition (ED) or standard-definition (SD) signals. A HDTV set has the highest resolution available and provides the ultimate home theater experience. An integrated Digital TV set provides consumers the most convenient, hassle-free way to experience Digital TV.

2.A Digital TV monitor and a separate digital tuner decoder box. This option allows consumers to upgrade to Digital TV when ready. As of March 1, 2007, all television receivers shipped in interstate commerce or imported into the United States must contain a digital tuner. Make sure you ask your retailer. If consumers choose to purchase only a Digital TV monitor, they will get a wide-screen format and improved picture. In order to receive an over-the-air signal with a Digital TV monitor, consumers must purchase a set-top decoder box. These boxes may be used with HD, ED or SD monitors.

3. An analog set. If consumers buy an analog set today, they will not receive any of the benefits of Digital TV, including the clearest pictures and sound ever available. Because an analog set does not have a digital tuner, consumers will have to purchase a digital tuner decoder box to watch Digital TV without the quality benefits offered by Digital Television.

Are the new DTV sets readily available?
Digital TV sets are available at both retail stores nationwide as well as online. Like CD players, computers and personal digital assistants, the prices for Digital TV sets continue to drop, as the technology becomes more prominent. In fact, prices for Digital TV sets have decreased by 50 percent over the last two years and are available in stores today starting at under $1,500.

Equally important, sales of DTV monitors and sets (monitors with integrated tuners) are rising each month. According to the Consumers Electronics Association, manufacturer-to-retailer sales figures of DTV monitors and sets in October 2001 showed a 113 percent increase over October of the previous year. October 2001 alone saw 187,464 Digital TV sets and monitors shipped from manufacturers to retailers. As of the end of October, 1,050,460 Digital TV units had been sold in 2001. CEA projects that 2.1 million Digital TV products will be sold in 2002, 5.4 million in 2004, 8 million in 2005 and 10.5 million in 2006.

Do I need to convert to digital right away?
The Digital TV transition is happening NOW!. More than 600 local stations are broadcasting a digital signal, ensuring that almost 94% percent of U.S. TV households live in a market with at least one digital signal. The government has loaned each broadcaster an additional TV channel to permit the transition to the new system. Throughout the transition, the government will review penetration of new Digital TV receiver sales every two years. This will ensure that the penetration of Digital TV is progressing as anticipated, so that the total conversion to digital will be a smooth one.

If I have digital cable, do I have digital television, and if I buy a Digital TV, will it work with digital cable?
Digital cable is not the same as digital television. In fact, most cable companies do not yet carry broadcasters' digital signals. Digital cable refers only to how signals are transferred across cable. Moreover, because there are not yet universal interoperability standards, a digital set that is plugged into a digital cable set-top box will only receive an analog signal, withholding all the advantages of digital television from a consumer. While inter-industry cooperation is yielding some progress on these issues, digital cable does not yet deliver digital signals into digital television sets.
