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.”)
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 tuner in order to view programs in the new digital TV transmission standard (which includes HDTV formats) on such a set.
Over-the-air digital set-top boxes 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 NTIA program digital-to-analog converter box, described below, used to convert free over-the-air digital broadcasts for viewing on an analog TV set.)
