DTV: The Future of Television

In the late 1980s, scientists and engineers began developing a new cable television system that would broadcast an all-digital television (DTV) transmission, and create the most significant advancement since color TV in the 1950s. The new technology is more efficient and allows for better sound and picture quality, as well as more programming options for consumers.

In 1998, the Federal Communications Commission (FCC) worked with Congress to pass legislation to require the conversion from analog television transmission to the new digital format. They found by converting to the DTV system, analog frequencies will be freed up to be used for public safety, such as police, fire and emergency rescue services. In addition, the frequencies will be used to advance commercial wireless service.

So what has changed so far? As of March 1, 2007 all televisions receivers shipped interstate or imported into the United States must contain a built-in digital tuner. The digital tuner will allow consumers to view free, over-the-air programming much like the programming received via antenna today, the difference being the digital capabilities for more programming and enhanced audio and video output.

Analog televisions without a built-in or external digital tuner will NOT capture the digital signal, so a digital-to-analog set-top converter box will need to be used in conjunction with an antenna. In addition, the digital tuner is not necessarily a HD (high definition) tuner, and must be specified as such; HDTV will pick up the high resolution transitions that the digital tuners will not.

The transition has been pushed back to help the public prepare for the change, and the FCC has also provided for those consumers without paid television to obtain converters. Starting January 1, 2008 and ending March 31, 2009, households in the U.S. can request coupons at $40 each to use towards the purchase of a digital-to-analog converter box.

So on February 17, 2009 all broadcasting will be in DTV format. The shift will create nationwide advancements in cable television, as well as public services. We are entering an age of technological innovation that will be touching every household in the country and simultaneously providing the same benefits to every consumer, entertainment and general safety.
