A still image or photo video compression standard. JPEG compression ratios vary from 20:1 to 40:1 with a lossless ratio of 5:1. JPEG is a symmetrical standard inasmuch as it takes the same amount of time to decompress as it does to compress video.
JPEG works best with smooth transitions and little motion.
Industry:Software
A device which uses an array of electronic switches to route a number of audio/video signals to one or more outputs in almost any combination. Production quality matrix switchers perform vertical interval switching for interference free switching. Matrix switchers may be operated with RS-232 or RS-422 controls, enhancing flexibility.

The full-screen video image must be reduced to fit into a graphics window (usually a fraction of the total computer display area), while at the same time maintaining a clear and complete image. To do this, it is important to remove or avoid visual artifacts and other “noise” such as degradation caused by pixel and line dropping, and interlacing problems from the scaling process. The challenges increase when dealing with moving images and the compression/decompression of large amounts of video data.
Industry:Software
The ability to stretch a “skin” over shapes that are in fact cross-sectional ribs.
Industry:Software
TV sets, VTRs, etc., that are designed to work using more than one technical standard; i.e., a VTR which can record both NTSC and PAL signals/recordings is a multi-standard machine.
Industry:Software
The magnetizing field strength needed to reduce flux density from saturation to zero.
Industry:Software
a) A wipe wherein the screen is divided into square areas, each of which can contain the video from either bus. Initially, each square contains the first bus video, and as the wipe develops, one or more squares switch to the opposite bus video until, at the completion of the wipe, all squares contain the second bus video. b) A type of wipe comprised of multiple boxes (a matrix of boxes) which turn on various parts of the “B” video during the course of a transition from the “A” video, until all the boxes have turned on the scene is all “B” video. This operates in either direction.
Industry:Software
A camcorder feature which takes out minor picture shakiness, either optically or electronically.
Industry:Software
A logarithm is the power to which a base (usually 10) must be raised in order to arrive at the desired value.
Industry:Software
A piece of magnetic tape which can be used to store two or more discrete signals.
