Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
The action of retaining in memory panel parameters (in the case of switchers), edit decision lists (in the case of editors), frames of video (in the case of machines like AVA, ESS and CGs).
Industry:Software
A line using two conductors to carry a signal, where one of the conductors is connected to ground.
Industry:Software
A compressor compatible with Indeo video interactive that handles data more quickly than the offline compressor. Videos that compress in hours can take minutes using the quick compressor. Compare Offline Encoder.
Industry:Software
A type of scalability where the enhancement layer(s) contain only coded refinement data for the DCT coefficients of the base layer. SNR scalability is aimed at transmission in noisy environments, and offers a form of graceful degradation. Under poor reception conditions, only the lower layer (which is covered by the highest error protection) is decoded.
The picture quality is then not the best, of course, but at least a picture is available. The alternative is a total loss of picture (the “brick wall” effect) below a certain SNR. The lower layer and the enhancement layer operate with the same resolution, but the enhancement layer may contain the higher frequencies of the picture.

a) A visual defect that occurs when the image being sampled moves too fast for the sampling rate. A common example is wagon wheels that appear to rotate backwards. b) An alias caused by violation of the Nyquist limit on sampling in time with frames.
Industry:Software
a) Amplitude compression of the signals corresponding to the white regions of the picture, thus modifying the tonal gradient.
b) The reduction in gain applied to a picture signal at those levels corresponding to light areas in the picture, with respect to the gain at the level corresponding to the midrange light value in the picture. Note: The gain referred to in the definition is for a signal amplitude small in comparison with the total peak-to-peak picture signal involved. A quantitative evaluation of this effect can be obtained by a measurement of differential gain.
The overall effect of white compression beyond bandwidth limiting is to reduce contrast in the highlights of the picture as seen on a monitor.
Industry:Software
a) The console device which allows an operator to move a pattern around the screen. The AVC has a rate positioner as opposed to an absolute positioner. The direction of pattern movement is the same as the direction in which the positioner is moved and the rate of pattern movement is proportional to the distance the positioner is moved from center.
When it is released, the pattern stops in its current position and the positioner returns to center. The 4100 has an absolute positioner whose angle and direction correspond to the location of the pattern on the screen. b) A joystick control that allows the origin of a wipe pattern to be moved within the active picture area.
Industry:Software
Preliminary edit of raw footage to establish tentative sequence, length of approximate sequence, and content of the eventual video program.
Industry:Software
A storyboard is an animator’s sketch, or rough of all the keyframes involved in a particular piece of animation. Used as a visual script or shooting plan.
