I/P/B
To efficiently store video on DVD, common elements among frames
are used in common, and different elements are recorded with each
individual frame. The frame that contains the common elements is
called an I-picture, a complete frame in itself. A P-picture is
calculated from past I or P-pictures. The frame that fills in the
spaces between the I-and P-pictures is called the B-picture.
I-pictures have the best picture quality, so they should be used
when making picture adjustments.
≥
Frame
Individual images in a video or on the television are called frames.
≥
Field
Half of the video information (video signal) in a frame is called a
field. With conventional TV systems, a single frame (a single
screen) consists of two fields.
≥
Frame still
The two fields are displayed alternately on the TV screen, so the
image may be blurry. However, the image quality is better than field
images.
≥
Field still
Only one field (half of the video information) is displayed on the TV
screen, so the apparent resolution is low. However, there is no
blurring on the screen.
The names given to the television picture modes depends on the make of your television. There may also be slight differences in how the pictures
appear on the screen. Refer to your television’s operating instructions for details.

picture mode your TV is set to.
