eliP/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 l-picture, a complete frame in itseft. 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.
eFrame
Individual images in a video or on the television are called frames.
eField
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.
eFrame 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.
eReld still
Only one field (haft of the video information) is displayed on the TV screen, so the apparent resolution is low. However, there is no blurring Onthe
screen.

picture mode your TV is set to.
