Frequently asked Questions about watching High-Definition TV (HDTV) and Digital TV (DTV)

How can I watch ABC ACTION NEWS in HD for free, over the air?

WFTS-DT, available on digital Channel 28.1, is a free, over-the-air broadcast. There is no need for a cable service or satellite dish. All you need is an HDTV television or a digital tuner and a TV antennae, the same kind you've used for your old analog signal. You can check with your local TV retailer for more advanced "smart" over-the-air antennas as well.

ABC ACTION NEWS's digital signal and HD programming is a free service. Any program that you enjoy currently on ABC ACTION NEWS on cable or satellite in the analog form is also available FREE over-the-air on WFTS-DT Channel 28.1.

What exactly do I need in order to receive HDTV?

For free reception, you'll need an antenna and an HDTV compatible television set or projector with built-in digital tuner. If the tuner is not built-in, you'll need to purchase a separate set-top digital tuner box. Ask your local electronics retailers about availability. Some receivers are bundled with cable or satellite services as well. Depending on your location, you may need either a small set-top antennae or a larger unit installed outside. Be aware that an HDTV signal is an all-on or all-off signal. Unlike the old analog signals, a digital signal does not weaker or stronger as you tune it in; either it's all there or, not there at all, depending on distance and signal strength.

The way you position your antenna is important. To help you receive the HDTV signal, you should know that ABC ACTION NEWS's transmitter is located in Riverview, FL.

What programs can I see in High Definition on WFTS-DT?

All of the local ABC ACTION NEWS newscasts are available in high definition. You'll find a list of ABC shows available in high definition at ABC.com.

What's the difference between analog and digital television sets?

The most obvious difference is the screen size. The current NTSC system uses a 4:3 picture ratio, which is somewhat square. Digital TV, however, uses 16:9 screen format that is considerably more horizontal, much like a movie screen. Consequently, you can view movies in a format much closer to what the film director intended, and view sports events in a much grander scale. Also, in NTSC analog format, your picture is made up of horizontal lines. In digital TV, however, your picture is composed of millions of individual picture elements (pixels) much like a digital camera or computer screen. Consequently, there is a fineness of detail and richness of color that the older NTSC system cannot match. The result is a stunningly clear television picture in your home.

What's the difference between 1080i and 720p?

There are two formats available for hi-definition television. First is 1080i, which is an interlaced scanning format similar to your analog television. Currently, CBS and NBC have adopted this format. The second format is 720p (progressive), which is a picture that is composed of pixels; similar to the way your computer screen operates. The ABC and FOX networks currently broadcast in this format. Keep in mind that some digital receiver/monitors that are capable of receiving the highest quality signals sometimes down-convert them to a lower-quality 480p format (SD, or standard definition) for display. Check with you local retailer to make sure you are getting a display capable of true high definition resolution.

What other extra services can I expect from HDTV?

Being a digital format, your HDTV set is able to interface with the Internet and your home computer. You can merely hook up the DVI output from your computer to your large screen display to view your computer's output.

You'll also receive other non-traditional programming, such as TV schedule guide information and other data services such as stock tickers, sports scores, news headlines and the like. Some broadcasters may choose to compress their digital signals into lower resolution, or a combination of both HD and SD programs (like public broadcasting) resulting in more channel streams.

As a bridge to the digital future, the federal government will make available a $40 coupon good towards the purchase of a digital to analog set-top converter. This box will enable you to use your old analog TV receiver to display the newer digital format. This will not, however, be a high definition picture. It will downgrade the high definition signal so that your non-digital TV can display the programming in a lower resolution.

Background

What is Digital Television?

DTV: A Federal Government Mandate for 2009. Here's what you need to know to be prepared for the Digital TV switch.

By law, television stations nationwide must switch from the old method of transmitting TV signals known as analog to digital television (DTV) on February 17, 2009. Television sets connected to cable or satellite will not be affected, and will continue to receive programming after that date. But those television sets not connected to cable or satellite, or without a DTV converter box, will not receive any television signal after the DTV switch.

Why the switch?

Under legislation passed by Congress - the Deficit Reduction Act of 2005 - free local broadcast television stations are required to turn off their analog channels on February 17, 2009, and continue broadcasting exclusively in the digital format.

What is DTV?

Digital television (DTV) is an innovative new type of over-the-air broadcasting technology that enables TV stations to provide dramatically clearer pictures and better sound quality.

DTV is more efficient and more flexible than the traditional broadcast technology known as analog. For example, DTV makes it possible for stations to broadcast multiple channels of free programming simultaneously (called multicasting), instead of broadcasting only one channel at a time. DTV technology can also be used to provide future interactive video and data services that are not possible with analog technology.

What is analog television?

Analog television service is the traditional method of transmitting television signals. Analog transmission has been the standard broadcast technology since the inception of television. Analog is not as efficient as digital television: it uses up much more of the valuable spectrum than digital, and TV stations can only transmit one channel of programming with an analog signal versus up to four or more programs with a digital signal in the same amount of spectrum. Analog is also susceptible to interference and "snow" that make a picture less clear.

What is the DTV transition?

The DTV transition is the switchover from analog (the traditional method of transmitting television signals) to exclusively digital broadcasting of free television programming. The transition from analog to digital television represents the most significant advancement of television technology since color TV was introduced. The DTV transition will be completed on February 17, 2009, as set by Congress. Television stations have been preparing for the transition from analog to DTV since the late 1990s, when they began building digital facilities and airing digital channels alongside regular analog broadcasts. Today, 1,624 out of 1,762 full power television stations nationwide offer digital programming.

What equipment do I need?

If you currently receive free over-the-air television programming on an analog television set, you will need a DTV converter box to continue to receive television service after February 17, 2009. DTV converter boxes will be available in early 2008. To help consumers cover the cost of the converter box, the National Telecommunications and Information Administration (NTIA) will be issuing up to two converter box coupons valued at $40 each to households in early 2008. Information about the DTV converter box coupon program is available at www.ntia.doc.gov.

What is a DTV converter box?

A DTV converter box is an easy-to-install electronic device that hooks up to your analog television set and over-the-air antenna and converts the digital television signal into analog, making it viewable on your analog TV. The National Telecommunications and Information Administration (NTIA) will issue up to two converter box coupons valued at $40 each to households to help defray the cost of the converter box.

How do I switch?

You can prepare for the transition to digital television by following one of three simple steps:

1) Purchase a DTV converter box that will convert the digital signal into analog for an existing television set.

The DTV converter box, sometimes referred to as a set-top box, is an electronic device that makes the new digital signal viewable on an older “analog” television set. DTV converter boxes will be available for purchase in early 2008, and are expected to cost between $50 and $70. To help consumers cover the cost of the converter box, the federal government will offer up to two converter box coupons valued at $40 each to households beginning in early 2008. Each coupon may be used toward the purchase of a single DTV converter box and the coupon program will be administered by the U.S. Department of Commerce through the National Telecommunications and Information Administration (NTIA) www.ntia.doc.gov.

You will still need an over-the-air antenna in addition to the converter box to receive a digital signal on your analog television set. Your current antenna should work the same as before.

2) Purchase a new television set with a built-in digital tuner.

Another option you may choose is to upgrade to a new television set with a built-in digital tuner. As with older sets, you will need an over-the-air antenna that provides quality reception of over-the-air analog television signals to pick up free digital broadcast programming from local stations. Before deciding to purchase a new digital TV, you should make sure your current TV doesn't already have a built-in digital tuner. Most sets sold in the last few years that are larger than 27 inches will likely have a digital tuner.

To check whether your TV set can receive over-the-air digital broadcast signals, take a look at your owner's manual or look on the set for an indication that it has a built-in Advanced Television Systems Committee (ATSC) tuner. You can also go to the manufacturer's Web site and check the capabilities of the set by manufacturer model number.

3) Subscribe to cable, satellite or a telephone company television service provider.

All of these services will allow you to receive digital television signals on your analog television set. No additional equipment is required if you decide to go this route. However, be sure to check that the pay service you choose carries all of the program services provided by the local broadcast stations.
