- Company Profile:
Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
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.
Industry:Software
The magnetising 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
The maximum value of the intrinsic coercive force.
The intrinsic coercivity is a basic magnetic parameter for the material and requires complete saturation of the sample for its measurement as does the saturation flux density.
Industry:Software
To perform a colour coordinate transformation by computation or by electrical, optical, or other means.
Industry:Software
In a uniformly magnetised sample of magnetic material, the product of the intrinsic flux density and the cross-sectional area.
Industry:Software
Parent of Panasonic and Quasar, majority owner of JVC, first company to demonstrate an HD camera and display in the U.S., has continued demonstrations, and developed the QUME and QAM ATV schemes, which popularised the idea of quadrature modulation of the picture carrier.
Industry:Software
In a sample of magnetic material for a given value of the magnetising field strength, the excess of the normal flux density over the flux density in vacuum.
Industry:Software
An operational image or signal carrying only transparency information and intended to overlay and/or control a conventional image or image signal. a) Without shine or gloss. Relatively unreflective of light.
Removal of a portion of a TV picture and replacement of it with another picture. b) A solid color, adjustable in hue, luminance, and saturation.
Matte is used to fill areas of keys and borders. Ampex switchers generate many internal matte signal keys. c) A film term used to describe the film effect analogous to a key. Sometimes this definition is carried over into video and used to describe a video key. d) A black and white high contrast image that suppresses or cuts a hole in the background picture to allow the picture the matte was made from to seamlessly fit in the hole.
Industry:Software
Graph of magnetic flux (B) plotted against the magnetising force (H) producing it. The value of B when H has dropped to zero is the residual magnetism, and the reverse force needed to reduce B to zero is known as the coercivity. Units used are: magnetising Force (H) in oersteds and Flux Density (B) in gauss. Coercivity is measured in oersteds.
