On February 17, 2009., full-power
TV stations in the United States will cease broadcasting on their current analog channels, and begin digital-only operations.
Why are TV broadcasters switching to DTV?
DTV
broadcast technology is more flexible and efficient than today's more
widespread broadcast technology, which is called "analog." For example,
rather than being limited to providing one analog programming signal, a
broadcaster will be able to provide a sharp "high definition" (HDTV)
program or multiple "standard definition" digital programs
simultaneously. Providing several program streams using the digital
spectrum is called "multicasting." The number of programs a station can
send using the digital spectrum depends on the level of picture detail,
also known as "resolution" in each programming stream. DTV can provide
picture resolution, interactive video, and data services that easily
surpass the capabilities of "analog" technology. Converting to DTV also
will free up parts of the scarce and valuable broadcast spectrum. Those
portions of the spectrum can then be used for other important services,
such as public and safety services (police and fire departments,
emergency rescue), and advanced wireless services.
When will the DTV transition be complete?
TV
stations serving all markets in the United States are airing digital
television programming today, although most will continue to provide
analog programming through February 17, 2009. At that point, full-power
TV stations will cease broadcasting on their current analog channels,
and the spectrum they use for analog broadcasting will be reclaimed and
put to other uses.
How do I get DTV?
Receiving
DTV signals over the air requires an antenna and a receiver that can
decode the digital signals. In general, an antenna that provides
quality reception of over-the-air analog TV signals (VHF and UHF) will
work for DTV reception. Cable subscribers may need new DTV equipment to
view DTV programming in digital format. You should ask your cable
provider what you will need and when. Cable subscribers may buy a
"Digital Cable Ready" (DCR) or "Plug-and-Play" television that plugs
directly into the cable jack and does not require a separate set-top
box. In order to receive scrambled programming and premium one-way
services, cable subscribers with a DCR TV will need to obtain a
CableCARD from their cable company. Alternatively, cable subscribers
may lease a separate set-top box from their cable provider or buy one
at a retail outlet. Satellite subscribers may need new DTV equipment to
receive and view high-definition digital programming. You should ask
your satellite company what you will need and when. A list of the
operating DTV stations is available at www.dtv.gov. Satellite TV
providers and most cable television systems are currently offering DTV
programming. Subscribers should check with their service providers to
see what programming is available in their areas.
Will I need a new TV if I have an analog TV?
When
full-power broadcast stations stop analog service, you still will be
able to use your analog TV with a set-top converter box. Converter
boxes for analog TVs receiving over-the-air broadcasts will be
available in retail stores at that time. These boxes receive digital
signals and convert them into analog format for display on your analog
TV. Beginning in 2008, your household may be able to obtain up to two
coupons worth $40 each toward the purchase of converter boxes. The
National Telecommunications and Information Administration (NTIA) has
responsibility for administering the coupon program and will issue
rules regarding the coupons. Additional information can be found at
www.ntia.doc.gov. If you are a cable or satellite subscriber, contact
your provider about whether you will need a converter box for your
analog TV.
What about digital receiver availability and FCC tuner requirements?
Remember,
even with a set-top converter box, your current analog TV will not
display the full picture quality of DTV. To enjoy the full picture
quality, you must have a DTV set or a separate DTV receiver and a
digital display monitor. The FCC requires that many new television
receivers sold in the U.S. today include the capability to receive
digital TV signals. By March 2007, all TVs (and other devices that are
designed to receive broadcast television signals) are required to have
digital tuners built in.
What do DTV sets look like, and what will they cost?
Most
DTV sets have wider screens than current analog TVs. The wider screens
allow for wider images that are similar to those you see in a movie
theater. DTV sets come in a range of sizes. As with most new consumer
electronics technologies, DTV sets have become less expensive since
their introduction a few years ago. Prices are expected to continue to
fall over time and will vary depending on screen size, display
technology, and other features.
What is the difference between Integrated DTVs and digital monitors?
An
Integrated DTV set is a digital television with a built-in digital
receiver and decoder. If you have an Integrated DTV and live in an area
served by a DTV broadcast station, you only need an antenna (preferably
an outdoor antenna) to receive over-the-air DTV broadcast programming.
Integrated TVs also can receive and display current analog signals. In
contrast, a digital monitor is not capable of receiving and tuning DTV
programming without additional equipment. A DTV set-top box must be
connected between the antenna and the monitor to receive and display
DTV programming that is broadcast over the air. Also, if you are a
cable or satellite subscriber, you may need a new set-top box to
receive digital broadcast content. Confirm with your retailer that the
DTV receiver or set-top box is compatible and has the proper connectors
to interface with the DTV monitor that you are purchasing. Many
monitors have a built-in analog receiver and can display analog TV
programming. They also can display video from DVD players and VCRs
through their connectors.
Will Integrated DTVs and Digital Monitors Display HDTV?
Integrated
DTV sets and digital monitors do not necessarily display programming in
full HDTV format. Some integrated sets and monitors will display DTV in
lower-resolution "enhanced definition" or "standard definition" format.
So although sets may be marketed with labels or descriptions that imply
HDTV resolution, check with your retailer before purchasing if you want
HDTV quality.
Why can't we have both DTV and the TV system we now have?
Broadcast
and wireless services depend on the use of the airwaves. DTV technology
is much more efficient than the current analog technology and will
allow the broadcast of more program content using less broadcast
spectrum. Transitioning to digital broadcasting will free up resources
for public safety and other new and innovative services for American
consumers.
