Basics

After February 17, 2009, standard analog televisions that get their programming from an over-the-air antenna will go dark. If you rely on an over-the-air signal, you will have to take action if you still want to watch television! For most viewers that means you’ll get a converter box so you can keep watching on your older TV set, you’ll subscribe to cable or satellite, or you’ll buy a digital television.

Hold on there, partner. Analog? Digital? You lost me!

If you haven’t bought a television recently, chances are you’ve got an analog TV. An analog television transmits images by “painting” lines on the screen via the TV’s internal electron gun. But in the process of transmission, the signal degrades, which means details can be lost. A digital television, in contrast, sends information in bit streams (that would be lines of data made up of ones and zeroes.) These signals don’t degrade and you can see the difference in a clearer picture.

Check out the links below for answers to the most common questions about the switch to all-digital.

Why DTV?

Digital is a new format for television broadcasting which has clearer images and better sound. A digital television is one that can receive and display the new format. The best way to describe the picture quality difference between digital and analog (older format) televisions is that of DVD compared to VCR.

DTV vs. HDTV?

DTV (digital television) and HDTV (high-definition television) are referring to the type of broadcast; SDTV (standard definition television) is referring to the type of TV. Digital television means that the broadcast is being sent out digitally. HDTV is a form of digital television and is the highest quality of broadcast today. SDTV allows you to receive and display a digital picture, but not HD.

When is DTV?

February 17, 2009. This date has been backed up a few times. Find out how plans for the switchover evolved.

How much is DTV?

What you spend to get digital television depends on a lot of factors. If you want to convert your analog television, you can pay around $50 for a converter box. Or if you want to go the whole hog and splash out with a surround-sound digital home theater and a 50-inch 1080i Plasma, you’re talking thousands.
