Defining High-Definition

What is HD, and how does it differ from regular TV? To learn more, here’s some helpful information about high-definition and your DIRECTV HD Receiver.

Types of TV Broadcasts

Analog TV is the type of TV broadcast you may be most familiar with. If you get your broadcasts via a standard off-air antenna, it’s the type you receive, and most broadcasts from local cable companies are analog as well.

Digital TV is a newer system for broadcasting TV signals delivering higher quality audio and video. “Digital TV” refers to a television that can receive and display digital images.

4SDTV (standard definition TV) is digital TV that offers a high picture quality that is better than older analog televisions. An SDTV can display an image at a resolution of 480i.

4EDTV (enhanced definition TV) is digital TV that can display a higher resolution picture than SDTV. An EDTV can display at 480i or 480p.

4HDTV (high definition TV) is digital TV that can provide the highest quality picture, at resolutions 1080i, 720p, 480p, or 480i.

See “Resolutions and Interlacing” on page 6, for an explanation of display resolutions.
