Panasonic PalmTheater DVD-LA95 Operating Instructions Manual page 45

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).
