What kinds of TV programming can I watch with the
DIRECTV
®
HD Receiver?
Your HD (High-Denition) Receiver lets you receive television programs from a wide range of sources, and display them on
virtually any TV or monitor.
Using the AIR IN, SATELLITE IN, and CABLE IN jacks on the back of the HD Receiver, you can receive television programs
from:
• HDTV and SDTV DIRECTV
®
programming via digital satellites (through the SATELLITE IN jack).
• Local off-air analog television broadcasts (NTSC), and local off-air digital broadcasts (ATSC) (through the AIR IN jack).
• Unscrambled analog cable TV services for unscrambled cable programming (through the CABLE IN jack).
To view cable TV or DIRECTV programming, programming subscriptions are also required.
Analog TV, Digital TV, NTSC, ATSC, SDTV, and HDTV
The following list shows the differences between the types of signals your HD Receiver can decode.
Analog TV – NTSC
Analog TV is the TV you’re probably most familiar with. Most of the TV broadcasts you receive via a standard off-air
antenna or from your local cable company are analog TV broadcasts. NTSC (National Television Standards Committee)
refers to the group that rst established the standards used for conventional analog television broadcasts and TV equipment.
Digital TV – ATSC
Digital television (sometimes called DTV) is a newer method of broadcasting TV signals that delivers higher quality audio
and video. Digital TV is broadcast in two sets of formats, SDTV and HDTV. ATSC (Advanced Television Systems Committee)
has been working to establish the standards for digital television broadcasts and digital television equipment — including
both SDTV and HDTV.
SDTV
SDTV is a digital TV format that provides a high quality picture at resolutions that can be displayed on standard TV
sets (see more on resolutions on the next page).
HDTV
HDTV is a digital TV format that provides the highest quality picture at resolutions that can be displayed on computer
monitors and HDTV-ready TV displays.
What equipment is required to view HDTV programming?
To view HDTV programming, you'll need a television set or HD monitor in addition to your HD Receiver. For access to
DIRECTV High-Denition programming, you'll need a triple LNB Multi-Satellite antenna, along with a DIRECTV HD Receiver
and an HD monitor.
To receive analog and digital off-air television broadcasts, you’ll need an off-air antenna (reception may vary based on
geographic location). To receive cable TV programming, you’ll need a cable TV connection (provided by your local cable
TV service provider).
