Digital TVs and Captioning
June 2005
Editor: You've probably heard the buzz about digital TV, and may have
wondered what's involved in upgrading to this new technology. Oh, and
are captions required, as they are for "regular" TV? Here's an
article from NVRC News with answers to these questions and more. You
might want to save this article. I bet it won't be long before you start
thinking about one of the new sets!

The FCC Requirements
Starting July 1, 2002 digital TVs were required by the Federal
Communications Commission (FCC) to include an 'EIA-708B' (DTVCC)
captioning decoder. Digital TV programs also must meet the same
requirements as conventional analog TVs. This means that all new TV
programs must be captioned 75% of the time for both digital and analog
TVs - and that goes up to 100% as of January 1, 2006. There are
exceptions for some commercials, for programs between 2 and 6 am, and
for some older programs.
Buying a Digital TV
Buying a digital TV can be complicated if you depend on captions some
or all of the time. It's rare to find a store where the sales people
know how to operate all the new captioning features in digital
televisions. It's also rare to find one that will connect its digital
televisions to real broadcasts rather than something on tape. This means
you may not get the complete ability to see how crisp and readable the
captions are, and how they compare with other digital TV choices. You
will have to be prepared to return the digital TV.
Helpful Hints From the FCC
The FCC has a website that is very helpful in understanding digital
TV. You can enter your zip code and then view a schedule of all the
digital programs being broadcast in your area. There's a section that
explains all the digital TV terms and a DTV Shoppers Guide. You can find
it at:
http://www.dtv.gov/
One of the sections also has tips you should know about DTV before
you buy, such as:
Compare DTV picture quality. DTV comes in several levels of picture
quality. The most common are: High Definition Television (HDTV),
Enhanced Definition Television (EDTV) and Standard Definition Television
(SDTV). HDTV is DTV at its finest. With HDTV, you can enjoy a true home
theater experience. EDTV is a step up from basic television. SDTV is the
basic display.
Make sure you have all the DTV equipment you need. DTV equipment can
be purchased as an integrated set or as separate components.
"Integrated" digital televisions have built-in tuners and a
monitor to display the programming. If you buy a DTV monitor (without an
integrated tuner), you will need a stand-alone tuner, cable set-top box,
or satellite set-top box to watch DTV.
HDTV is not the same as DTV. HDTV requires special equipment, so make
sure to ask about HDTV-capable equipment and talk to your cable or
satellite provider to verify you have the proper set-top box to view
HDTV.
"Digital cable ready" (or "plug-and-play")
televisions are also available. These can be used to receive digital
cable TV (and often HD over cable) without a separate set-top box. A
CableCARD is needed to watch certain cable programming. These
televisions do not work directly with satellite - you still need a
set-top box to view satellite programming.
Compare screen types. You have a choice in DTV screens. Today, the
primary options are: Cathode ray tube (CRT) screens - traditional color
television screens updated for digital; Rear Projection TVs - rear
projection TVs can create brilliant, wide angle pictures on ever-larger
screens; LCD screens - are very thin and produce extremely clear
pictures, but are currently expensive and limited in size; Plasma
screens - create a bright, clear picture up to enormous sizes while
remaining very thin.
Ask what connectors you need to make sure your new DTV set works with
your other electronic equipment (DVD player, digital video recorder (DVR),
camcorder, VCR, computer, video games, and other equipment). The
electronic equipment you have now should work with your new DTV, but you
may need new connectors. Make a list of what you have now and ask your
retailer what you need to connect the components.
