depend on location, terrain and environmental factors. Outdoor or attic

antennas will generally be more effective than a set-top antenna. For cable,

check with your local cable provider to find out if they will carry the DTV signal

in your area.

Digital Picture Formats

DTV supports eighteen (18) Advanced Television System Committee (ATSC) ＊

display formats, which are variations of the four (4) following formats : 1080i

(interlaced), 720p (progressive), 480p (progressive) and 480i (interlaced). The

larger the number means the higher the resolution of the picture.

Interlaced Scan

For interlaced pictures, the odd number lines (picture information) are scanned,

creating field 2. The two fields are interlaced to provide the entire image (one

frame). This process takes 1/30th of a second and is invisible to human eye.

Progressive Scan

For progressive pictures, all lines in an entire frame are scanned sequentially in

1/60

of a second. With progressive scan, you will generally not see the thin

black horizontal scan lines (venetian blind effect) associated with an interlaced

picture.

Digital Audio

For all HDTV formats, Dolby＊＊ Digital surround sound (also commonly

referred to as AC-3＊＊ or DD 5.1) is the audio standard. AC-3 will provide

CD-quality sound. The system provides 3 separate audio channels for the front

speakers (left, center, right), 2 channels for the rear surround sound speakers,

plus one channel for subwoofer sound. You will need an external audio system

capable of decoding the AC-3 encoded sound to get the full surround sound

effect. Otherwise, it can be connected directly to your TV or audio system

using only the stereo (left/fight) audio outputs.

Note: The stereo audio outputs are Dolby Surround compatible. You can

connect a Dolby Surround Pro Logic＊＊ decoder (not included) to the stereo

audio outputs and receive surround sound.
