What is Digital TV?

In 2009, TV stations transitioned from analog broadcasting (NTSC) to digital broadcasting (ATSC). Digital television, or DTV, is both the content that is received and the technology which makes it viewable in homes. DTV offers high-quality pictures and sounds, multiple programming choices from single stations (multicasting), and interactive options. The analog system is outdated and has been replaced by a more flexible system.

What’s the difference between standard definition (SD) and high definition (HD)?

Not all digital signals are high definition. HDTV and Digital TV are not the same thing; HDTV is one format of digital TV. There are three kinds of DTV signals:

  • Standard Definition (SDTV) which is basic quality of both analog and digital; transmission can be in either traditional (4:3) or widescreen (16:9).
  • Enhanced Definition (EDTV) which is a step up from analog and comes in widescreen (16:9) or traditional format (4:3). It provides better picture quality than SDTV, but not as good as HDTV.
  • High Definition (HDTV) with widescreen format (16:9), has the highest resolution and picture quality of all broadcast formats.

What if I subscribe to digital cable or satellite?

Cable and satellite subscribers are not affected by the DTV transition.  Your equipment will continue to work as it did before.

Where can I find out more information about DTV?

Visit the FCC’s website for DTV,, for up-to-date information about digital TV.  You may also call 1-888-CALL-FCC (1-888-225-5322).

Who should I contact about closed captioning problems?

For captioning problems during non-emergency programming, you may file a written complaint with either the FCC or your video programming distributor (i.e., your cable or satellite TV service). If you do not pay for cable, satellite, or another subscription video service, WTIU viewers can receive informed assistance with an immediate closed captioning complaint by calling Television Master Control at (812) 855-9239, faxing to (812) 855-0729 or e-mailing to If the need is not immediate, or the WTIU viewer would prefer to send the comment via postal mail, letters can be sent to:
