Why Are Broadcast TV Stations Switching to All-Digital?
- Congress mandated the conversion to all-digital television broadcasting, also known as the digital television (DTV) transition, because all-digital broadcasting will free up frequencies for public safety communications (such as police, fire, and emergency rescue). Also, digital is a more efficient transmission technology that allows broadcast stations to offer improved picture and sound quality, as well as offer more programming options for consumers through multiple broadcast streams (multicasting). In addition, some of the freed up frequencies will be used for advanced commercial wireless services for consumers.
What Do I Need To Do To Be Ready For The DTV Transition?
- What you need to do depends on the source of your television programming, whether you receive programming over-the-air or from a paid provider such as a cable or satellite TV company.
How Do I Receive Digital Broadcasts If I Don’t Subscribe To Cable Or Satellite?
- If you receive only free over-the-air television programming, the type of TV you own, either a digital TV or an analog TV, is very important. Consumers who receive only free over-the-air television may view digital programming through a TV set with a built-in digital tuner (integrated DTV) or a digital-ready monitor with a separate digital tuner set-top box. (Both of these digital television types are referred to as a DTV). The only additional equipment required to view over-the-air digital programming with a DTV is a regular antenna, either on your roof or a smaller version on your TV such as “rabbit ears.”
- If you have an analog television, you will have to purchase a digital-to-analog set-top converter box to attach to your TV set to be able to view over-the-air digital programming (see “What About My Analog TV?” below).
How Do I Know Whether I Own a DTV?
- As of March 1, 2007, all television receivers shipped in interstate commerce or imported into the United States must contain a digital tuner. In addition, effective May 25, 2007, the Commission required sellers of television receiving equipment that does not include a digital tuner to disclose at the point-of-sale that such devices include only an analog tuner, and therefore will require a digital-to-analog converter box to receive over-the-air broadcast television after the transition date. Retailers must inform consumers by prominently displaying the following text if they are selling TV equipment with only an analog tuner:
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, after May 25, 2007, all television equipment being sold should contain a digital tuner, or should be identified at the point-of-sale as not having one. Be sure to look for this label if you are purchasing a new TV.
- As for how to determine whether your television equipment purchased prior to May 25, 2007 is a 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” or “Digital Tuner Built-In.” “Receiver” may be substituted for “Tuner,” and “DTV,” “ATSC,” or “HDTV” (high definition television) may be substituted for “Digital.” 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 digital programming in “high definition.”)
What About My Analog TV? Will It Still Work?
- After February 17, 2009, you will be able to receive and view over-the-air digital programming with an analog TV only by purchasing a digital-to-analog set-top converter box. Between January 1, 2008, and March 31, 2009, all U.S. households will be able to request up to two coupons, worth $40 each, to be used toward the future purchase of eligible digital-to-analog converter boxes. Eligible converter boxes are for the conversion of over-the-air digital television signals, and therefore are not intended for analog TVs connected to a paid provider such as cable or satellite TV service.
- The National Telecommunications and Information Administration (NTIA) is administering the coupon program. For more information, visit the NTIA website at www.dtv2009.gov. The Commission’s DTV website, www.dtv.gov, also provides information for consumers on the upcoming digital-to-analog converter box coupon program. More detailed information regarding NTIA’s coupon program, what digital-to-analog converter boxes will be eligible, where and when they may be purchased, and the related costs involved will be provided by the Commission and NTIA as the commencement of the coupon program on January 1, 2008, approaches.
How Much Will DTV Improve My TV Viewing?
- While picture quality will vary according to whether you watch digital programming in high definition (HDTV) or standard definition (SDTV) format, over-the-air digital programming provides a better viewing experience than over-the-air analog programming, as long as you have good quality reception through your antenna.
