Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
William and Karen Glenn, researchers for NYIT in Dania, Florida, who developed the VISTA ATV scheme. They are often cited for their work indicating that human vision cannot simultaneously perceive high spatial detail and high temporal detail.
Industry:Software
A) The black burst signal used to synchronise all the devices in the studio or station. b) Sync generated within the studio and used as a reference for generating and/or timing other signals (i.e., sync gens).
Industry:Software
A) A form of low-frequency interference, appearing as a narrow horizontal bar moving vertically through the picture. This is also observed on an oscilloscope at field or frame rate as an extraneous voltage pip moving along the signal at approximately reference black level. b) Slang for visual error, i.e., dropout on tape, spikes at switcher pattern boundaries.
Patterns that jump off screen or any other aberration. c) Slang for a fault in data transmission or other error that does not cause a total lock up.
Industry:Software
A) A colour wheel of basic pigments. All the hues of the rainbow encircle the cone’s perimeter. b) The wavelength of the colour which allows colour to be distinguished such as red, blue, and green. Often used synonymously with the term tint. It is the dominant wavelength which distinguishes a colour such as red, yellow, etc. Most commonly, video hue is influenced by a camera’s white balance or scene lighting. Video colour processors, such as the Video Equalizer, are the main tools used to adjust and correct hue problems. c) One of the three characteristics of television color. Hue is the actual colour that appears on the screen. See Chroma and Luminance.
d) Attribute of a visual sensation according to which an area appears to be similar to one of the perceived colors, red, yellow, green, and blue, or to a combination of two of them.
Industry:Software
A term used to define the voltage/time function of a single DAC step until the output video level has settled to within ±1 LSB of the final value. Glitches are apt to appear in output video as the input to the DAC changes from: 0111 1111 to 1 000 0000.
Industry:Software
Colour space system based on the values of Hue, Saturation, and Intensity. Intensity, analogous to luma, is the vertical axis of the polar system. The hue is the angle and the saturation is the distance out from the axis.
Industry:Software
A separate channel that allows additional rotations to be superimposed on an image and, in 3D systems, “motion on motion” in an effect.
Industry:Software
Nearly identical to HSI except Intensity is called Lightness. Both serve the same function.
Industry:Software
A data set with all data essence or metadata elements defined in the relevant data essence standard or Dynamic Metadata Dictionary.
