What is digital television (DTV)?
The switch to digital television (DTV) will let you enjoy a dramatically clearer picture, better sound quality, and more programming choices. DTV is more efficient and flexible than the traditional broadcast technology known as analog. Since television came into being, stations have broadcast programs using an analog signal, where subtle changes in the waveform define the image and sound. With digital television, the signal is broadcast as “bits and bytes,” the same as computers use. That means DTV can deliver high-definition pictures, surround-sound audio, and several channels all at the same time. By June 12, 2009, the Federal Communications Commission is requiring broadcasters to turn off their analog transmitters and broadcast only digital signals.
