  1. 1. Digital Television (DTV) What is DTV? What You Need to Know By Worldwidesatellites
  2. 2. What is DTV? Digital Television (DTV) is an advanced broadcasting technology that will transform your television viewing experience. DTV enables broadcasters to offer television with better picture and sound quality. It can also offer multiple programming choices, called multicasting, and interactive capabilities. source: dtv.gov
  3. 3. The Transition to Digital TV 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 set June 12, 2009 as the final date that full power television stations can broadcast analog signals. As of June 13, 2009, full power television stations will only broadcast digital, over-the-air signals. Your local broadcasters may make the transition before then, and some already have.
  4. 4. The digital transition is underway. Prepare now! On Feb. 17, some full-power broadcast television stations in the United States may stop broadcasting on analog airwaves and begin broadcasting only in digital. The remaining stations may stop broadcasting analog sometime between April 16 and June 12. June 12 is the final deadline for terminating analog broadcasts under legislation passed by Congress.
  5. 5. 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). Continue…..
  6. 6. 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. Continue…..
  7. 7. 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. Further, DTV can provide interactive video and data services that are not possible with analog technology.
  8. 8. What You Need to Know  What is the date set by Congress for the end of full- power analog television broadcasting?  Do I have to wait until after June 12, 2009 to watch DTV?  Digital Television Tuners  Digital Television Quality Levels
  9. 9. What is the date set by Congress for the end of full-power analog television broadcasting? Congress has set June 12, 2009 as the final deadline for terminating analog broadcasts. Under the law, on Feb. 17, some full-power broadcast television stations in the United States may stop broadcasting on analog airwaves and begin broadcasting only in digital. The remaining stations may stop broadcasting analog sometime between April 16 and June 12.
  10. 10. Do I have to wait until after June 12, 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).
  11. 11. Digital Television Tuners The Commission's digital tuner rule specifies that as of March 1, 2007, all new TVs must include digital tuners. This rule prohibits the manufacture, import, or interstate shipment of any device containing an analog tuner, unless it also contains a digital tuner. Despite this prohibition on manufacture and shipment, retailers may continue to sell analog-only devices from existing inventory. As a result, at the point of sale, many consumers may not be aware that this equipment will not be able to receive over-the-air- television signals after June 12, 2009. source: dtv.gov
  12. 12. Digital Television Quality Levels There are many quality levels of digital television programming. The most common are: •Standard Definition TV (SDTV ) •Enhanced Definition TV (EDTV) •High Definition TV (HDTV) source: dtv.gov
  13. 13. 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. source: dtv.gov
  14. 14. Enhanced Definition TV (EDTV) EDTV is a step up from Analog Television. EDTV comes in 480p widescreen (16:9) or traditional (4:3) format and provides better picture quality than SDTV, but not as high as HDTV. source: dtv.gov
  15. 15. High Definition TV (HDTV) HDTV in widescreen format (16:9) provides the highest resolution and picture quality of all digital broadcast formats. Combined with digitally enhanced sound technology, HDTV sets new standards for sound and picture quality in television. (Note: HDTV and digital TV are not the same thing - HDTV is one format of digital TV.) source: dtv.gov
