Yamaha DVD-S796 Owner's Manual - Page 35

For your reference ³I/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. ³Frame Individual images in a video or on the television are called frames. ³Field 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. ³Frame 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. ³Field 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. How different kinds of software appear on your television DVD software is recorded in a variety of picture formats, and how they appear on your TV depends on the software, the kind of TV you have, and the picture mode your TV is set to. ³Letterbox refers to pictures where black bands appear at the top and bottom. ³Pan and scan refers to pictures where part of the picture is cut off so it fills the whole screen.
