Panasonic DVD-LA95 Operating Instructions Manual page 47

Pan&Scan/Letterbox
In general, DVD-Video are produced with
the intention that they be viewed on a
widescreen television with an aspect ratio of
16:9. This means you can view most mater-
ial with the intended aspect ratio on a
widescreen television.
Material with this ratio will not fit onto a stan-
dard television with an aspect ratio of 4:3.
Two styles of picture, "Pan&Scan" and
"Letterbox", deal with this problem.
Pan&Scan: The sides are cut off so the
picture fills the screen.
Letterbox: Black bands appear at the top
and bottom of the picture so the
picture itself appears in an
aspect ratio of 16:9.
Playback control (PBC)
If a Video CD has playback control, you can
select scenes and information with menus
(called menu play in these instructions).

Play list
This is a collection of scenes. It enables you
to play these scenes in succession or to
select specific ones to play.
Program
This is a division on DVD-RAM.
Sampling rate
This is the number of samples of sound
taken per second during conversion to a
digital signal. Sampling frequency is ex-
pressed in kilohertz (kHz). A high sampling
frequency results in a sound close to the
original when played back.
Title/Chapter
DVD-Video are divided up into large sec-
tions, titles, and smaller sections, chapters.
The numbers allocated to these sections
are called title numbers and chapter
numbers.
Track
This is the smallest division on DVD-Audio,
CD, and Video CD, and usually equates to a
single song.
