Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
A number used to compare the amounts of light passed through optical systems, such as camera lenses. Transmission aperture takes into consideration both the f-stop (geometric aperture) and the amount of light absorbed or reflected in the optical system.
Industry:Software
Circuit that allows the microprocessor system to output signals to other devices.
Industry:Software
A colour relationship scheme in which a colour table contains available colour values; an index into this table is used to refer to a color. If a desired colour is not found in the table, it may be matched to the closest available entry or an existing entry may be overwritten.
Industry:Software
Function of entering edit in- and out-points in the time-code format. Preceding the numeric entry with a + or - adds to or subtracts from already existing edit points.
Industry:Software
A term used to describe a condition as seen on the waveform monitor when the black peaks extend through reference black level.
Industry:Software
The fine details in a video picture. A picture appears sharp when it contains fine details and has good contrast. Picture sharpness is easily lost during the recording/playback process. Advanced video enhancement equipment is used to improve picture sharpness, especially contrast, and can precompensate for potential losses which might alter an image during processing.
Industry:Software
The amount of resolvable detail in the vertical direction in a picture. It is usually expressed as the number of distinct horizontal lines, alternately black and white, which can be seen in a test pattern.
Vertical resolution is primarily fixed by the number of horizontal scanning lines per frame. Beyond this, vertical resolution depends on the size and shape of the scanning spots of the pickup equipment and picture monitor and does not depend upon the high-frequency response or bandwidth of the transmission medium or picture monitor.
Industry:Software
A) The effect of a spotlight falling on a video scene, and the switcher feature that allows this to be accomplished. On the AVC, the spotlight control adjusts attenuation of the A bus video. A typical spotlight effect is obtained by selecting the same source on both buses, a soft bordered circle wipe, and using size and position control. Many other effects are also possible with this feature. b) A highlight effect produced by a fullstrength video signal shaped by a wipe pattern and an attenuated (darkened) signal from the same video source. This is activated by selecting spotlight on the M/E effects group of buttons, and adjusting spotlight control on the pattern adjust group of controls to darken the desired area.
Industry:Software
A standard to be used for transmitting signals to the home, not necessarily for producing them. The scanning structure of NTSC is identical for both production and transmission, but this need not be the case in ATV schemes. For example, an HDEP standard of 1125 scanning lines might be used with a transmission standard of 1050 lines.
Standards converters translate one standard into another.
