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, e 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.
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.
• Frame still
The two fields are displayed alternately on the TV screen, so the image may be blum/. 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.
DVD software is recorded in a variety of picture formats, and how they appear on your "IV depends on the software, the kind of'IV you have, and the
picture mode your TV is set to.
• Letterbox refers to pictures where black bands appear at the top and bottom.
• Pan and scan refers to pictures where part of the picture is cut off so it fills the whole screen.
