Pan and Scan — dynamic cropping technique used to translate between materials with different
aspect ratios. Pan and Scan is used to translate movies shot on wide screen film formats to 4:3
television display. In the pan and scan process, the image is cropped to the new aspect ratio and
the transfer operator pans within the wider original image to include important details that are
near the edge. (These details would be lost by a simple cropping technique.) Pan-and-scan
movies don't have black bars (letterboxing) and completely fill the television screen.
Path — the sequence of directories that must be traversed to get from one directory to another.
On the Internet, a path is essentially the directions to a given folder, page, graphic, etc. See
Absolute Path, Relative Path and URL.
Pause — EventStream event that pauses a movie at a specified time.
P-frame (Predictive Frame) — MPEG difference frame that looks to previous frames. Same as a
