Digital Television (DTV) is an entirely new technology that will ultimately replace today’s analog television system. Digital signals are transmitted using computer code – ones and zeroes – which means they are less susceptible to interference and provide a higher quality picture and sound than analog.
High-definition TV (HDTV) is the best quality DTV. HDTV’s sound and picture quality are many times better than today’s analog TV. DTV also can be standard definition (SD) [good] or enhanced definition (ED) [better].
What you need to watch DTV:
DTV (including HDTV) is available over-the-air using a standard antenna or via digital cable or satellite. No matter how you receive your TV signal (cable, satellite or over-the-air), you will need DTV equipment to watch the DTV programming.
DTV equipment may be purchased as an all-in-one or component solution.
“Integrated” DTV sets with built-in tuners are an all-in-one solution for DTV – they include a digital tuner to receive over-the-air DTV broadcasts and a monitor to display the programming.
A “component” solution includes a DTV monitor (screen) without a DTV tuner (these monitors are sometimes labeled “HD Ready”). Monitors must be paired with a cable or satellite set-top box, or stand-alone DTV tuner.
“Digital cable ready” (or ”plug-and-play”) televisions are also available that can be used to receive digital cable TV without a separate set-top box. A CableCARD that can be plugged into the set is needed for certain cable programming.
Analog TVs will need additional equipment to receive over-the-air television when the DTV transition ends.
