picture blur.
IPB display (DVD): With the MPEG2
which is one of the video display
methods of DVD, each picture is di-
vided into the following three pic-
ture types before being coded in digi-
tal signal.
I-picture (in-frame coding): This
is the standard video and can con-
stitute a picture by itself. As the high-
est 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 predic-
tion coding): Picture calculated by
comparing the previous and next
pictures (I-pictures or P-pictures).
This picture type contains least
amount of video information.
Dynamic range: Difference between
the minimum reproducible audio
signal and maximum reproducible
audio signal.
