The Digital Transition
What is the digital TV (DTV) transition?
The switch from analog to digital broadcast television is
referred to as the digital TV (DTV) transition. In 1996, the U.S. Congress
authorized the distribution of an additional broadcast channel to each broadcast
TV station so that they could start a digital broadcast channel while
simultaneously continuing their analog broadcast channel. Later, Congress
mandated that February 17, 2009 would be the last day for full-power television
stations to broadcast in analog. Broadcast stations in all U.S. markets are
currently broadcasting in both analog and digital. After February 17, 2009,
full-power television stations will broadcast in digital only.
Return to Questions
Why are we switching to DTV?
An important benefit of the switch to all-digital
broadcasting is that it will free up parts of the valuable broadcast spectrum
for public safety communications (such as police, fire departments, and rescue
squads). Also, some of the spectrum will be auctioned to companies that will be
able to provide consumers with more advanced wireless services (such as wireless
broadband).
Consumers also benefit because digital broadcasting allows stations to offer
improved picture and sound quality, and digital is much more efficient than
analog. For example, rather than being limited to providing one analog program,
a broadcaster is able to offer a super sharp “high definition” (HD) digital
program or multiple “standard definition” (SD) digital programs simultaneously
through a process called “multicasting.” Multicasting allows broadcast stations
to offer several channels of digital programming at the same time, using the
same amount of spectrum required for one analog program. So, for example, while
a station broadcasting in analog on channel 7 is only able to offer viewers one
program, a station broadcasting in digital on channel 7 can offer viewers one
digital program on channel 7-1, a second digital program on channel 7-2, a third
digital program on channel 7-3, and so on. This means more programming choices
for viewers.
Return to Questions
What do I need to do to be ready for the end of analog TV broadcasting?
Because Congress mandated that the last day for full-power
television stations to broadcast in analog would be February 17, 2009,
over-the-air TV broadcasts will be in digital only after that date. If you have
one or more televisions that receive free over-the-air television programming
(with a roof-top antenna or “rabbit ears” on the TV), the type of TV you own is
very important. A digital television (a TV with an internal digital tuner) will
allow you to continue to watch free over-the-air programming after February 17,
2009. However, if you have an analog television, you will need a
digital-to-analog converter box to continue to watch broadcast television on
that set. This converter box will also enable you to see any additional
multicast programming that your local stations are offering.
To help consumers with the DTV transition, the Government
established the Digital-to-Analog Converter Box Coupon Program. The National
Telecommunications and Information Administration (NTIA), a part of the
Department of Commerce, administers this program. Every U.S. household is
eligible to receive up to two coupons, worth $40 each, toward the purchase of
eligible digital-to-analog converter boxes. Beginning in January of 2008, the
NTIA has begun accepting applications for coupons. The coupons may only be used
for eligible converter boxes sold at participating consumer electronics
retailers, and the coupons must be used at the time of purchase. (Please note
that these coupons will expire 90 days after mailing). Manufacturers
estimate that digital-to-analog converter boxes will sell from $40 to $70 each.
This is a one-time cost. For more information on the Digital-to-Analog Converter
Box Coupon Program, visit
www.dtv2009.gov, or call 1-888-388-2009 (voice) or 1-877-530-2634
(TTY).
Cable and satellite TV subscribers with analog TVs hooked up
to their cable or satellite service should not be affected by the February 17,
2009 cut-off date for full-power analog broadcasting.
Return to Questions
Do I have to wait until after February 17, 2009 to watch DTV?
No, digital television is available now. If you watch
over-the-air television today, you should be able to receive all or most of your
local stations’ digital signals if you have a DTV receiver. You may view high
definition and multicast programming from your local stations. Check your local
program listings or contact your local TV stations to find out more about the
digital television available now. The FCC’s special website,
www.dtv.gov, has more information on digital
television, or call 1-888-225-5322 (TTY: 1-888-835-5322).
Return to Questions
Will the February 17, 2009 date for the end of full-power analog television broadcasting be pushed back?
Federal law mandates that February 17, 2009 is the
last day of full-power analog television broadcasting. Government
agencies, industry, public interest groups, and other interested
organizations are working hard to make sure that the deadline is met and
that everyone is prepared for the end of full-power analog television
broadcasting.
Return to Questions
If I have an older analog television, will I have to throw it away after February 17, 2009?
No. A digital-to-analog converter box will allow you
to continue using your existing analog TV to watch over-the-air digital
broadcasts. You do not need to get rid of your existing analog TV. In
addition, analog sets should continue to work as before if connected to
a subscription service such as cable or satellite TV. Also, analog sets
should continue to work with gaming consoles, VCRs, DVD players, and
similar products that you use now.
Return to Questions
Your Television
If I want a new TV, will I have to buy a High Definition TV (HDTV) to watch digital broadcast television after the transition?
No. It is important to understand that the DTV transition is
a transition from analog broadcasting to digital broadcasting. It is not a
transition from analog broadcasting to High Definition broadcasting. Digital
broadcasting allows for High Definition broadcasts, but High Definition is not
required, and you do not need to buy a HDTV to watch digital TV. A Standard
Definition DTV (which is simply a TV with an internal digital tuner), or a
digital-to-analog converter box hooked to an analog TV, is all that is required
to continue watching over-the-air broadcast television. Digital broadcast
television includes Standard Definition (SD) and High Definition (HD) formats.
You can watch High Definition programming on a Standard Definition DTV (or on an
analog TV hooked to a digital-to-analog converter box), but it won’t be in full
High Definition quality. It is also important to know that Standard Definition
DTVs are comparably priced to similar sized analog TVs.
Return to Questions
How can I be sure that I am buying a digital TV (DTV)?
By law, beginning March 1, 2007, all television
reception devices (including TVs, VCRs, DVRs, etc.) imported into the
U.S. or shipped in interstate commerce must contain a digital tuner.
Retailers may continue to sell analog-only devices from existing
inventory, but must prominently display on or near the analog-only
device a Consumer Alert label with this advisory:
CONSUMER ALERT
This television receiver has only an analog broadcast
tuner and will require a converter box after February 17, 2009, to receive
over-the-air broadcasts with an antenna because of the Nation’s transition to
digital broadcasting. Analog-only TVs should continue to work as before with
cable and satellite TV services, gaming consoles, VCRs, DVD players, and similar
products. For more information, call the Federal Communications Commission at
1-888-225-5322 (TTY: 1-888-835-5322) or visit the Commission’s digital
television website at: www.dtv.gov.
Therefore, all television equipment being sold should
contain a digital tuner, or should be identified at the point-of-sale as not
having one. Be aware of this label and the limitations of analog-only devices if
you are purchasing a new TV or other TV equipment.
Return to Questions
How do I know if I already have a digital TV (DTV)?
Many DTVs and digital television equipment will have
labels or markings on them, or statements in the informational materials
that came with them, to indicate that they contain digital tuners. These
labels or markings may contain the words “Integrated Digital Tuner,”
“Digital Tuner Built-In,” “Digital Receiver,” or “Digital Tuner,” “DTV,”
“ATSC,” or “HDTV” (High Definition television). If your television
equipment contains any of these labels or markings, you should be able
to view digital over-the-air programming without the need for a
digital-to-analog converter box. (Remember, you do not need an HDTV to
view free over-the-air digital programming. As long as your television
equipment contains a digital tuner, you can view over-the-air digital.
An HDTV is only necessary if you want to view High Definition
programming in full HD quality.) You should also check the manual or any
other materials that came with your television equipment in order to
determine whether it contains a digital tuner.
If your television set is labeled as a “Digital Monitor” or
“HDTV Monitor,” or as “Digital Ready” or “HDTV Ready,” this does not mean it
actually contains a digital tuner. Thus, you still will likely need a separate
set-top box which contains a digital tuner in order to view over-the-air digital
programming.
Over-the-air digital set-top boxes for Digital or HD
“Monitors” can be purchased at retail stores. Cable and satellite TV providers
also sell or lease digital set-top boxes for their specific services. (Note: the
digital set-top box described here is not the same as the digital-to-analog
converter box, described above, used to convert free over-the-air digital
broadcasts for viewing on an analog TV set.)
If your television set is labeled as “analog” or “NTSC,” and
is NOT labeled as containing a digital tuner, it contains an analog tuner only.
If you cannot determine whether your television set or other
television equipment contains a digital tuner, you are advised to check your
equipment for the manufacturer name and model number, and then contact your
consumer electronics retailer, or the manufacturer, to determine whether it
contains a digital tuner. This information also may be available online through
the manufacturer’s website.
Because most broadcast stations in all U.S. television
markets are already broadcasting in digital, consumers can watch DTV today. You
can contact your local broadcast stations to determine the channel numbers on
which the stations are currently broadcasting digital programming. You should
then ensure that your television is set up to receive over-the-air programming
(as distinguished from being connected to a paid provider such as cable or
satellite TV service), and then tune to the over-the-air digital channels to see
if your set can receive the digital broadcast programming.
Return to Questions
What is the difference between “Integrated” DTVs and DTV or HDTV “Monitors”?
An Integrated DTV set is a television with a
built-in digital tuner (also referred to as “a DTV”). A digital tuner is
also sometimes called a DTV decoder or DTV receiver. If you have an
Integrated DTV, you will not need any additional equipment, with the
exception of a broadcast antenna (either a rooftop antenna or “rabbit
ears” connected to the set), to receive over-the-air digital broadcast
programming. Integrated DTVs can also receive and display analog
broadcast programming, so you can continue watching analog broadcasts.
In contrast, a DTV Monitor is not capable of receiving
digital broadcast programming without additional equipment; it is simply a
display device without the processing capability for DTV reception. A digital or
HD set-top box must be connected between the antenna and the monitor to receive
and display over-the-air digital or HD programming.
If you have a digital or HD “Monitor” and would like to
purchase a digital or HD set-top box to view over-the-air programming, confirm
with your retailer that the set-top box is compatible with your Monitor.
Return to Questions
What about my VCR, DVD player, camcorder, and gaming console? Will I be able to use them with a digital television set?
Yes. Digital television sets are “backward
compatible,” meaning existing analog equipment (VCRs, DVD players,
camcorders, video games, etc.) will work on digital TV sets. However,
their video will only be displayed in the maximum resolution that is
available with each analog product. Manufacturers are producing a number
of different connectors to hook equipment together and improve picture
and sound quality when DTVs are used with existing analog equipment.
Check with your retailer to determine the types of connectors that will
work with your equipment.
Return to Questions
How do I get DTV or HDTV programming?
In order to receive over-the-air digital programming (as
opposed to digital programming provided by a paid provider such as cable or
satellite TV service), you will need: (1) a DTV (a TV with a digital tuner) or
an analog TV connected to a digital-to-analog converter box and (2) a
broadcast antenna (either a rooftop antenna or “rabbit ears” connected to your
set). In general, an antenna that provides quality reception of over-the-air
analog TV broadcasting will work for digital TV broadcasting.
A listing of the U.S. TV stations that are broadcasting
digital programming is available at
http://www.fcc.gov/mb/video/files/dtvonair.html. Satellite TV providers and
many cable systems are currently offering digital programming. Subscribers
should check with their service providers to see what digital programming is
available in their area.
Return to Questions
Will I need a special antenna to receive DTV over-the-air?
In general, dependable reception of over-the-air
digital TV programming will require the same type of signal reception
equipment that currently works to provide good quality reception of
analog TV programming. If you need a roof-top antenna to receive analog
TV broadcasts, the same antenna generally will work to receive digital
TV broadcasts. You should not have to purchase new antennas that are
marketed as “digital ready” or “HD ready.”
Return to Questions
What will happen to the old analog TVs that will be replaced by DTVs? Will there be an effort to recycle them?
There are recycling programs for those who choose to
discard old analog TVs or other old electronic products (but remember,
analog TVs can continue to be used after the transition). One such
program is myGreenElectronics. Through this program you can learn about
disposal options and locate recycling programs near you. Go to
http://www.mygreenelectronics.org for more information.
Return to Questions
Cable and Satellite
Does the DTV transition affect TV sets that are connected to cable
services?
No. If you subscribe to cable service, the DTV transition should not
affect any TV sets that are connected to your cable services. The DTV
transition applies only to full-power broadcast television stations –
stations that use the public airwaves to transmit their programming to
viewers through a broadcast antenna.
Return to Questions
Is the FCC making cable companies switch to digital service?
No. Cable companies are not required to switch to digital service. Cable
companies may choose to make their service all or partly digital, but they
are not required to change from the analog service they offer today. In
fact, the FCC requires cable companies to continue to provide local stations
in analog as long as they provide any analog service, even after February
17, 2009.
Return to Questions
Can my cable company make me get a box to receive the cable channels I
receive today without a box?
Some cable companies have decided to switch to digital service. This is a
business decision made by the cable companies and is not required by the
federal government. Your cable company may decide to move certain cable
channels off of its analog service tier and onto a digital service tier, or
it may decide to switch to all-digital service at once, so that there is no
analog service tier for any subscribers. If your cable company decides to
move some or all of the channels it provides onto a digital service tier, it
may notify you that you need to get “digital cable” equipment to continue
receiving that cable service. This may include renting or purchasing a
digital cable set-top box or purchasing a digital cable ready TV equipped
with a “CableCARD” slot. The digital cable equipment is different from the
digital-to-analog converter boxes that are used to receive over-the-air
broadcast signals.
Return to Questions
How do I know if I already have digital programming through my cable or satellite TV service?
You may receive digital programming if you subscribe
to a digital or HD package from your provider and you are viewing the
digital programming on a digital set. However, the digital cable tier
and satellite TV service are not necessarily DTV. Your cable or
satellite TV system may be using digital technology as a more efficient
way of delivering analog programming to you. If you have an analog
television set, then you are probably not getting digital, even though
the reception may be somewhat improved. Check with your cable or
satellite TV provider to find out what kinds of programming you can
receive, and what equipment you need to receive it.
Return to Questions
My cable operator offers a digital cable package. Is this the same as HDTV?
No. “Digital cable” and high definition programming
on cable are not the same. If you want to watch HDTV programming on
cable, you will need to subscribe to your cable provider’s HDTV package
and view the programming on an HDTV set. You may also need a set-top box
or other equipment to view HDTV programming. Check with your cable
provider to find out what kinds of programming you can receive, and what
equipment you need to receive it.
Return to Questions
Do cable TV networks, like CNN, MSNBC, Lifetime, etc., have to switch to digital broadcasting as well?
No. The current requirement to switch from analog to
digital only applies to full-power broadcast TV stations, which use the public
airwaves to provide free over-the-air programming. However, as cable providers
convert to digital transmissions over their systems, you may need to subscribe
to their digital tier to continue to receive this non-broadcast programming.
Return to Questions
Can my cable system move programming to a digital tier that makes me subscribe to digital service?
Your cable system decides when and whether to carry
programming on a digital tier, which may mean that you will need digital
equipment. However, all of your local stations will continue to be
available in analog format for as long as your cable system offers any
analog service.
Return to Questions
Will cable customers with analog TVs have to buy or rent a set-top box from their cable company? If so, how much will it cost?
First, it's important to know that the February 17,
2009 deadline for the digital television transition only applies to
full-power broadcast stations. Cable companies are not required by the
government to transition their systems to digital, and can continue to
deliver channels to their customers in analog. Cable companies are
actually required by FCC rules to continue offering local broadcast
stations to their customers in analog as long as they offer any analog
service. This requirement will continue for at least three years after
February 17, 2009. The Commission will decide in 2011 whether the
requirement should be continued beyond February 17, 2012. This means
that customers who receive analog cable service (without a cable set-top
box) will be able to continue to do so.
However, for business reasons (among other things, digital
is much more efficient than analog), cable companies may be interested in
transitioning their systems from analog delivery to digital delivery. If a cable
company makes the business decision to go all-digital (meaning it will stop
offering any channels to its customers in analog), it must ensure that its
analog customers can continue to watch their local broadcast stations. This may
require customers with analog televisions to get a set-top box. If the cable
company provides the customer with a set-top box, any costs related to it will
be determined by the cable company. Therefore, it is recommended that analog
cable customers contact their cable company to ask if a set-top box will be
needed, when it will be needed, and if there will be a cost.
It is also important to note that a cable set-top box is
different from a digital-to-analog converter box. A digital-to-analog converter
box is necessary only for analog televisions that receive their programming
over-the-air using a rooftop antenna or "rabbit ears" connected to the set. A
digital-to-analog converter box is not necessary for a TV connected to a paid
television service such as a cable or satellite TV provider. Information on any
set-top boxes needed for a paid service such as cable or satellite should be
obtained from the service provider.
Return to Questions
Does the DTV Transition affect TV sets connected to satellite TV
service?
The DTV transition will not affect satellite TV subscribers who receive
their local TV stations through their satellite dishes. Satellite TV service
is a digital service and all satellite subscribers must have a set-top box
connected to their TVs to receive the satellite-delivered programming. As a
result, there should be no change in service for satellite subscribers
unless the local TV stations are not provided by the satellite carrier. If
you subscribe to a satellite TV service, you should check with your provider
to find out if you receive a local TV station package through your satellite
dish.

Return to Questions
Can I hook up more than one TV and video recorder to a single digital-to-analog converter box?
You will need one digital-to-analog converter box
for each TV set or other device (such as a VCR) that only has an analog
tuner. The digital-to-analog converter box basically replaces the analog
tuner in one piece of equipment. So if you want to use your analog TV
and VCR at the same time (for example, to watch one program and record
another simultaneously), you will need two digital-to-analog converter
boxes.
Return to Questions
Will digital-to-analog converter boxes (used to convert over-the-air digital TV broadcasts for viewing on analog sets) also convert digital closed captioning?
Yes. FCC rules require that digital-to-analog
converter boxes be able to convert over-the-air digital closed
captioning for display on analog TV sets. See
http://www.fcc.gov/cgb/consumerfacts/dtvcaptions.html.
Return to Questions
I have an old antenna that attaches to my TV with two wires. Will I be able to use a converter box with this antenna?
Yes, but you will need to get two adapters (also called "baluns" or "matching transformers," which are pictured below). Unscrew the existing twin-lead antenna wire from your TV “Antenna In” twin-lead terminals. Attach the existing twin-lead antenna wire to the twin-lead terminals on the
twin-lead adaptor (first picture below). Then plug the twin-lead
adaptor’s coaxial connector into the “Antenna In (RF)” port on the Converter Box. Using coaxial wire, plug one end into the “Out To TV (RF)”
port on the Converter Box. Plug the other end into a coaxial adaptor
(second picture below). Then attach the coaxial adaptor to your TV “Antenna In” twin-lead terminals.

General Questions
What about my portable, battery-powered analog
television? Will I be able to use it to watch broadcast television after February 17, 2009?
Portable, battery-powered analog televisions can receive over-the-air
digital programming if they are connected to a digital-to-analog
converter box and a separate broadcast antenna. The battery-powered
analog television must have an "antenna in" port in order to connect it
to a digital-to-analog converter box. Also, if local utility power
service is not available, another power source will be needed to supply
power to the digital-to-analog converter box. There are several options
available for consumers to supply back-up power to a digital-to-analog
converter box. These external power sources include rechargeable battery
packs, uninterruptible power supplies, car battery adapters, and small
power generators. Also, there is at least one converter box manufacturer
that offers a separate battery pack for its converter box. Check with
your local and online retailers for further information on these
devices.
Another option for consumers is to obtain a battery-powered digital
television. Battery-powered digital televisions are marked with words such
as “Integrated Digital Tuner,” “Digital Tuner Built-in,” “Digital Receiver,”
“DTV,” “ATSC” or “HDTV.” Check with your local electronics stores or online
retailers for product availability.
It is also important to note that consumers still can turn to their
battery-powered radios for important information during weather emergencies.
Return to Questions
Will the AM/FM radio in my analog TV still work after February 17, 2009?
Although the digital television transition does not affect AM/FM
radio broadcasting, the functioning of an integrated radio within an
analog television depends on the device and your particular
configuration.
If there is no digital-to-analog converter box attached to the
radio/television combination unit, the radio in your television will
continue to function as it did before.
If there is a digital-to-analog converter box attached to your
radio/television combination unit, and the unit relies on the external
antenna connected to the converter box for radio reception, the radio will
function if the digital-to-analog converter box contains an analog pass-through
feature. The NTIA maintains a list of analog pass-through capable boxes at
www.ntiadtv.gov/cecb_list.cfm
(denoted with an asterisk). The radio will also function if the unit is not
connected to a digital-to-analog converter box.
If the radio/television combination unit relies on a separate antenna for
AM/FM radio that is not connected to a digital-to-analog converter box, it
should be able to receive AM/FM radio broadcasts whether the unit is connected
to a digital-to-analog converter box or not.
Return to Questions
My radio currently receives the audio portion of TV channels. Will it work after February 17, 2009?
Radios that are designed to tune the audio portion of analog TV
broadcasts will not be capable of receiving the audio portion of digital
TV broadcasts. You may wish to consider obtaining new portable digital
televisions or radios that can receive the audio portion of digital
television broadcasts as they become available on the market.
Return to Questions
My local AM/FM radio station re-broadcasts a TV channel’s audio. Will the radio station continue this service after February 17, 2009?
The audio and video in a digital television broadcast signal is
combined in a manner that may require an AM/FM re-broadcaster of TV
station audio to install additional equipment to continue such a
service. Please check with your local radio AM/FM broadcaster to see if
they will maintain TV channel audio re-broadcasting.
Return to Questions
My local television station re-broadcasts AM/FM radio stations on a television channel. Will I still be able to listen to these radio station re-broadcasts on my television after February 17, 2009?
If your local television station re-broadcasts radio stations on a full-power
television station channel, you will need a digital-to-analog converter box to
watch that television channel and hear any associated audio on an analog TV.
Return to Questions
Will digital television stations continue to provide emergency alerts?
Yes. Digital television stations are required to continue operating the
Emergency Alert System (EAS). For more information about EAS, please visit

What are low-power (LPTV), Class A, and TV translator stations and how does the DTV transition affect them?
You may have noticed that Congress mandated that
“full-power” TV stations will not be able to broadcast in analog after
February 17, 2009. While the majority of the viewed TV broadcast
stations are full-power stations, three other categories of TV stations
exist – “low-power” stations, “Class A” stations, and “TV translator”
stations. There is currently no deadline for these stations to convert
to digital broadcasting.
The FCC created low-power television (LPTV) service in 1982
to provide opportunities for locally-oriented television service in small
communities. These communities may be in rural areas or may be individual
communities within larger urban areas. LPTV stations are operated by diverse
groups and organizations including high schools and colleges, churches and
religious groups, local governments, large and small businesses and individual
citizens. More than 2,100 licensed LPTV stations are in operation. LPTV
programming can include satellite-delivered programming services, syndicated
programs, movies, and a wide range of locally-produced programs.
Class A TV stations are former LPTV stations that have
certain interference protection rights not available to LPTV stations. These
stations are technically similar to LPTV stations, but unlike LPTV stations must
air at least three hours of locally-produced programming each week and comply
with most of the non-technical regulations applicable to full-power stations.
Approximately 600 licensed Class A TV stations are in operation.
A TV translator station rebroadcasts the programs of a
full-power TV broadcast station. Translator stations typically serve communities
that cannot receive the signals of free over-the-air TV stations because they
are too far away from a full-power TV station or because of geography (such as
uneven terrain or mountains). Many of the 4,700 licensed TV translator stations
operate in mountainous or more remote areas of the country.
There are several ways to determine whether the broadcast
stations you view over-the-air (with a rooftop antenna or “rabbit ears” attached
to your TV) are LPTV, Class A or TV translator stations. Class A stations are
required to visually or aurally identify their stations with their community of
license and call sign (that includes the suffix “-CA” for Class A) at sign on,
sign off, and on an hourly basis. LPTV stations also must regularly identify
their station call sign. When locally originating programming, they must
visually or aurally identify their call sign and community of license at sign
on, sign off, and hourly. LPTV call signs may consist of four letters followed
by the suffix “-LP” (for low power) or, alternatively, five characters beginning
with the letters K or W followed by two numbers (their operating channel) and
two additional letters. Also, some TV translators are identified by the
full-power TV stations whose signals they rebroadcast. Further, LPTV, Class A,
and TV translator stations may regularly broadcast information as to their
status, and may include information regarding the DTV transition.
While the February 17, 2009 deadline for ending analog
broadcasts does not apply to low-power, Class A, and TV translator stations, the
FCC will require these stations to convert to digital broadcasting some time
thereafter. Nearly 2,000 of these stations have been authorized to construct
digital facilities and some are broadcasting in digital already. The FCC is
currently considering the remaining issues involved with the low-power digital
transition and will make decisions regarding these stations in the future.
If you have an analog-only television that receives free
over-the-air programming (with a roof-top antenna or “rabbit ears” on the TV),
you will need to purchase a digital-to-analog converter box in order to watch
digital broadcast television. Each U.S. household is eligible to receive two $40
coupons to be used toward the purchase of two digital-to-analog converter boxes.
The National Telecommunications and Information Administration (NTIA) is
administering the coupon program. (Please note that these coupons will expire 90
days after mailing). More information can be found at
www.dtv2009.gov,
or by calling 1-888-388-2009 (voice) or 1-877-530-2634 (TTY).
If you purchase a digital-to-analog converter box to watch
digital broadcasts on an analog TV and also wish to continue watching analog
LPTV, Class A, or TV translator stations, you should purchase a converter box
with “analog pass-through” capability, which allows analog broadcast signals to
pass through the converter box to be tuned by your analog TV. NTIA’s TV
Converter Box Coupon Program has certified converter box models that have analog
pass-through capability. A current list of coupon-eligible converter boxes is
available at
https://www.ntiadtv.gov/cecb_list.cfm. The converter box models that
have analog pass-through capability are noted on the list with an asterisk next
to them. In addition, NTIA will mail a list of current coupon-eligible converter
boxes, noting with an asterisk those that have analog pass-through capability,
to each household that receives converter box coupons. You can also check with
your retailer to determine whether the converter box you are purchasing has
analog pass-through capability.
If you purchase a digital-to-analog converter box without
analog pass-through capability, you may have to connect an antenna switch or a
signal “splitter” to bypass the box if you wish to view analog TV broadcasts.
Check with the manufacturer of the digital-to-analog converter box and your
retailer if you need instructions on how to connect the box to view broadcasts
from both analog and digital stations.
Viewers should look for information from their LPTV, Class
A, and TV translator stations about plans to convert from analog to digital
broadcasting. Viewers should also visit www.fcc.gov for any updates on the
digital transition of low-power, Class A, and TV translator stations.

What are my options for watching over-the air analog TV broadcasts from LPTV or translator stations after the digital transition?
To watch analog LPTV and translator station
broadcasts received through an antenna, you can take one or more of the
following actions:
-
Keep an analog TV connected to a broadcast antenna to view
analog LPTV and translator station broadcasts.
-
Purchase a digital-to-analog converter box that has analog
pass-through capability. For a current list of digital-to-analog converter
boxes that have been certified by NTIA as eligible for the TV Converter Box
Coupon Program, click on
https://www.ntiadtv.gov/cecb_list.cfm and look for the boxes with the asterisk (*)
next to them. Analog pass-through allows you to watch analog television
broadcasts as well as digital television broadcasts through the converter box.
-
Purchase a digital-to-analog converter box without analog
pass-through capability, and then connect a "splitter" or antenna switch to
receive both analog and digital broadcasts. Check with your consumer
electronics retailer if you need instructions on how to connect the box to
view broadcasts from both analog and digital stations.
-
Purchase a digital television set. A television with a
built-in digital tuner can receive both analog and digital stations, so you
will be able to watch both digital programming and analog LPTV and translator
station programming for as long as these stations continue to broadcast in
analog.
-
Subscribe to a cable television or other pay service that
carries the analog station(s) you want to watch.

Will I be able to use parental controls like the V-chip with digital TV the same way I now can with my analog TV?
Yes. The V-chip is a technology that enables parents
to block television programming based on a program’s rating. The ratings
are encoded within the television signal. The V-chip reads the encoded
rating information of each program and blocks shows according to the
parents’ blocking selections. FCC rules require that V-chips be built
into digital televisions and other DTV reception devices just as they
are in analog televisions. You can learn about the ratings system, also
known as “TV Parental Guidelines,” at
www.fcc.gov/vchip.

Why doesn’t the picture on my digital television fill up
the entire screen? Why do bars on the top and bottom or sides of the picture appear with different programming?
Traditional analog TV has an aspect ratio of 4:3 (almost
square). This means that a TV screen is 4 inches wide for every 3 inches it
is tall. Most digital televisions have an aspect ratio of 16:9 (rectangular)
and are called “widescreen.” The 16:9 aspect ratio more closely approximates
the look of movies and the amount of programming that is being offered in
16:9 is increasing.
When the aspect ratio of the television program and your
television set do not match, bars on the top and/or sides of the image may
appear to ensure that the image is not distorted.
In order to properly display 16:9 content on a 4:3 set, your
digital television or digital-to-analog converter box may place bars at the
top and bottom of the image – a process called “letterboxing.”
Similarly, to properly display 4:3 content on a 16:9
television set, bars may be placed on the sides of the screen – a process
called “pillar boxing.”
Also, some programs are “letterboxed” or
“pillar boxed” during broadcast. For example, many commercials are produced
in analog with a 4:3 aspect ratio, but are broadcast with letterboxing for a
“modern” look or to leave room for text or subtitles. When such a commercial
is aired during a widescreen (16:9) program, it will also be pillar-boxed.
This results in a 16:9 format broadcast that already has bars above and
below it. When such a broadcast is viewed on a 16:9 set, it results in bars
appearing above, below, and on the sides – a result called a “postage
stamp.”
Many digital-to-analog converter boxes and digital televisions
allow you to “zoom” into the image to eliminate the bars. This may result in
part of the image being cut off or “cropped.” Some digital-to-analog
converter boxes and digital televisions also provide the ability to alter
the image to fit the screen, either by “stretching” or “squeezing” the
image. Please consult the owner’s manual of your digital television or
digital-to-analog converter box for details on how to eliminate the bars
through zooming, stretching or squeezing the image on your screen.

Why do some programs look “clearer” than others on my digital television?
Depending on your television, you may notice the resolution of the
picture changing between programs. With a higher resolution television,
lower resolution channels or programming will appear in their lower
resolution. Therefore, switching between a channel or program that is
broadcast at a high resolution to a channel or program of a lower resolution
will result in a visible loss of image quality.
Resolutions that broadcasters may use include:
Standard Definition TV (SDTV)
- SDTV is the basic level of quality display and resolution
for both analog and digital. Transmission of SDTV may be in either
the traditional (4:3) or widescreen (16:9) format and consists of
480 interlaced lines of resolution. |
|
Enhanced Definition TV (EDTV) -
EDTV is a step up from analog television and Standard Definition
digital television. EDTV comes in widescreen (16:9) or traditional
(4:3) format and provides 480 progressively scanned lines of
resolution. This is approximately twice as much resolution as SDTV
and is the format most often found on DVDs. |
|
High Definition TV (HDTV) -
HDTV in widescreen format (16:9) provides the highest resolution and
picture quality of all digital broadcast formats. It consists of
either 1080 interlaced or 720 progressively scanned lines of
resolution and includes the ability to transmit digital surround
sound. |

Will my building’s master antenna system work with digital TV signals?
What is a Master Antenna System?
Some people who live in an apartment building, condominium, home owners’
association, high-rise, co-op or other multiple dwelling unit (MDU) receive
local TV stations through a master antenna system, sometimes called a common
antenna or a MATV system. These antenna systems receive TV signals through an
antenna on the roof or in a central location and provide the signals through
wiring in the building or development that connects to the TV set in individual
apartments or homes. Some of these systems provide the local TV stations for
free, and some of them are packaged with satellite programming and charge a fee.
These shared or community antenna systems are sometimes known as “satellite
master antenna systems,” or “SMATVs”. Also, some people who live in MDUs receive
local TV stations through a private cable operator (PCO) serving just one
building or homeowners’ development.
How is this different from having cable in my building?
If you subscribe to the cable TV service offered in your city or town, or if
you subscribe individually to satellite TV service and receive your local
channels through your own satellite dish, you will continue to receive your
local broadcast channels without having to buy a digital television or DTV
converter box.
Will my apartment building master antenna system work with digital TV
signals?
If you receive local TV stations through a shared antenna or private cable
system serving just your building or homeowners’ development, then you need to
check with your building, landlord, condo association, co-op association, home
owners’ association, or private cable operator to find out if you need to take
action to continue to receive local stations after the analog signals are turned
off on February 17, 2009.
Many of these antenna systems will need some adjustment so that the digital
signals can be received and delivered through the wiring to your apartment or
home for you to view with a digital converter box or with a digital television
set. Each building’s antenna system is different, so check with your landlord,
building manager, homeowner or condo association or video provider to find out
how you are affected.
