Given two databases with the same number of vertices, a metamorphosis causes the first to become the second. This is an animation tool.
Industry:Software
In a CAV system, this refers to the overall amplitude of all three signals that make up the CAV signal and is measured as the peak-to-peak voltages of the three video signals (usually including sync on luminance levels).
Industry:Software
The range in measured luminance between the lightest and the darkest element of a luminous scene or its display.
Industry:Software
The process of combining two video signals such that the resultant video signal is instant-by-instant the same as the brighter of the two weighted input signals. For example, at 50% fader, the brighter of the two videos predominates. The net effect of this type of mix is a superimposed appearance, with the picture balance controlled by the fader.
Industry:Software
a) A signal that can electronically “cut a hole” in the video picture to allow for insertion of other elements such as text or a smaller video picture.
b) A video that has been overlaid on top of another video. Keys may W2 W1 B2 B1 SD 5% C Grat. B 2% K2T 5% be either determined by the luminance or brightness of the key video, or determined by the chroma or hue of the key video. c) A push-button.
Industry:Software
Contribution level quality encoded high definition television signals. Typically split into two levels: high level at approximately 140 Mbps and low level at approximately 39 Mbps (for high definition with the studio, 270 Mbps is being considered). These levels of compression are necessary for signal routing and are easily re-encoded without additional compression artifacts (concatenation) to allow for picture manipulation after decoding. DS-3 at 44.736 will be used in both terrestrial and satellite program distribution.
Industry:Software
The luminance range that can be displayed on a CRT is the ratio of maximum to minimum luminance on the tube face. The maximum practical output is determined by beam current, phosphor efficiency, shadow-mask distortion, etc. The minimum is the luminance of that portion of the tube face being scanned with beam current set to cut-off. The contributions from room illumination, external and internal reflections, etc., must be recognized.
