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 pic-
ture fills the screen.
Letterbox: Black bands appear at the top
and bottom of the picture so the
picture itself appears in an as-
pect 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 se-
lect 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
sections, 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.
