Usually, but not always, referring to the accuracy of a screen display to show how the final result will look. For example, a word processor screen showing the final layout and typeface that will appear from the printer.
Industry:Software
The function used to turn or rotate an image. Rotate turns the image around the intersection of the X, Y, and Z axes, the center point for rotation. Rotate does not move or reposition the center point of the image.
Industry:Software
A coded still picture consists of a video sequence containing exactly one coded picture which is intra coded. This picture has an associated PTS, and the presentation time of succeeding pictures, if any, is later than that of the still picture by at least two picture periods.
Industry:Software
Interconnect consisting of two wires. One wire transports the luminance signal while the other transports the multiplexed chrominance signals. This system allows efficient dubbing between recorders because recorders normally record the luminance on one tape channel and the two color difference signal on a single channel. To record the two-color difference signals on a single channel, the two-color difference signals are compressed and then multiplexed together. Transferring the two video signals between tape recorders in the two-wire format prevents the two tape recorders from having to do additional signal processing.
Industry:Software
A method of transferring movies with an aspect ratio of 16:9 to film, tape, or disc to be shown on a conventional TV with a 4:3 aspect ratio. Only part of the full image is selected for each scene. Pan and Scan is the opposite of “letterbox” or “widescreen.”
Industry:Software
Video: The signal that describes the distribution of luminance levels within the image and the equation for deriving that information from the camera output.
Television, Composite Color: A signal that has major control of the luminance. Note: The signal is a linear combination of gamma-corrected primary color signals.
Industry:Software
The term “enhanced television” designates a number of different improvements applicable to 525/60 Hz and 625/50 Hz television systems. They include all television systems not specified in CCIR Report 624-4, Characteristics of Television Systems and Report 801-4, The Present State of High-Definition Television, either with unchanged or new radiation standards and without specification of aspect ratio.
Industry:Software
