2-1. Sending Signals

2. IMPORTANT OVERVIEW

Digital broadcasting is a new way of sending programs over the airwaves with superior qual-

ity video and audio. The DIRECTV

High-Definition Receiver enables you to take full advan-

tage of digital broadcasting. To fully enjoy it, you need to understand the ways the 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.
