What Is the Difference Between Analog and DTV Broadcasting?
DTV is an advanced broadcasting technology that replaces analog over-the-air broadcasting. Digital broadcasting allows stations to offer improved picture and sound quality along with a host of other advantages over analog broadcasting. 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. Digital television offers many advantages over analog television for viewing broadcast TV. A broadcaster also can use its DTV signal to provide video and data services that are not possible with analog technology. Full-power television stations serving every market in the U.S. are delivering DTV programming.
