Digital broadcasting is a new way of sending programs over the airwaves with superior quality video and audio. The DIRECTV® HD Receiver enables you to take full advantage of digital broadcasting. To fully enjoy it, it is helpful to understand the ways that program signals are sent.

There are two types of TV signal formats; analog (often called NTSC format; National Television System Committee) and digital (ATSC format; Advanced Television System Committee). Digital formats are classified into three categories: High-Definition (HD), Enhanced Definition (ED), and Standard Definition (SD) according to the resolution or digital picture quality.

There are also three ways that program signals can be received; over-the-air (NTSC, ATSC), cable and satellite.
