Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
The number of discrete sample measurements made in a given period of time. Often expressed in megahertz for video.
These samples are then converted into digital numeric values to create the digital signal.
Industry:Software
A spatial resolution smaller than that of a pixel. Although digital images are composed of pixels, it can be very useful to resolve image detail to smaller than pixel size, i.e., sub-pixel. For example, the data for generating a smooth curve on television needs to be created to a finer accuracy than the pixel grid itself, otherwise the curve will look jagged.
Again, when tacking an object in a scene or executing a DVE move, the size and position of the manipulated picture must be calculated, and the picture resolved, to a far finer accuracy than the pixels, otherwise the move will appear jerky.
Industry:Software
To make a file system that is accessible from a specific directory on a workstation temporarily inaccessible.
Industry:Software
A digital video interface which uses twisted pair wiring and 25-pin D connectors to convey the bits of a digital video signal in parallel.
There are various component and composite parallel digital video formats.
Industry:Software
Colour intensity extracted from a “smooth” set of predetermined values varying from an initial to a final intensity.
Industry:Software
Special programme that simulates the logical operation of the microprocessor. It is designed to execute machine language programmes on a machine other than the one for which the programme is written. This allows programmes for one microprocessor to be debugged on a system that uses another processor.
Industry:Software
A chart with special patterns, placed in front of a television camera to generate a known reference signal that can be used to adjust the camera and all the equipment downstream from the camera.
Industry:Software
Initialization process whereby storage elements within a system are preset to defined conditions when power is first applied.
Industry:Software
In digital video, the sampling is orthogonal if the luminance and color-difference samples are generated from pixels arranged in common, continuous vertical and horizontal lines on a rectilinear grid that remains constant field/frame to field/frame.
Industry:Software
Self-contained portion of a programme that performs a welldefined task. May be used at any place in the same program.
