The information in this tip originally appeared in the HDTV 101 online class.
- Analog: An analog TV cannot display progressive-scan DVD or HDTV. It can show only standard-definition programs such as those found on regular TV, cable, or satellite–including digital cable and DirecTV or Dish Network.
- Digital: A digital television, sometimes called a DTV, can also display progressive-scan DVD and almost always HDTV.
- EDTV: This stands for Enhanced-Definition TV, and usually it describes a television that can display HDTV signals but doesn’t have enough resolution to really do them justice. Most often it applies to plasma TVs and denotes 852×480 pixels.
- HDTV: High-definition televisions, or HDTVs, can display standard TV, progressive-scan DVD, and HDTV signals. They’re by far the most common type of digital television.
