Frame still/Field still (DVD, VCD): Types of still pictures ob-
tained by temporarily stopping a moving picture. The frame
still picture may produce blur in the picture because it displays
two specific fields alternately, but the picture quality is higher.
The field still picture has lower picture quality because it uses
half the picture information of frame still, but is not accompa-
nies with picture blur.
IPB display (DVD): With the MPEG2 which is one of the video
display methods of DVD, each picture is divided into the fol-
lowing three picture types before being coded in digital signal.
I-picture (in-frame coding): This is the standard video and
can constitute a picture by itself. As the highest picture quality
can be obtained, the still image of I-picture is most suitable for
use when adjusting the picture quality.
P-picture (forward prediction coding): Picture calculated
based on past pictures (I-picture or P-picture).
B-picture (bidirectional prediction coding): Picture calcu-
lated by comparing the previous and next pictures (I-pictures
or P-pictures). This picture type contains least amount of video
information.
P.B.C. (PlayBack Control) (VCD): VIDEO CDs carrying mes-
sages such as "Playback Control Capable" can be played inter-
actively by selecting the desired play position or information
in hierarchical structures while watching the menus displayed
on the TV screen.

erations using the menus and icons displayed on the TV screen.
