Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
An organized assembly of equipment, personnel, procedures, and other facilities designed to perform a specific function or set of functions.
Industry:Software
Expressed on the waveform monitor by the voltage level of the whitest whites in the active picture signal. Defined as the range of light-to-dark values of the image which are proportional to the voltage difference between the black and white voltage levels of the video signal.
Video gain is related to the contrast of the video image.
Industry:Software
A picture defect caused by unequal delay (phase shifting) of different frequency components within the signal as they pass through different impedance elements - filters, amplifiers, ionosphere variations, etc. The defect in the picture is “fringing”-like diffraction rings at edges where the contrast changes abruptly.
Industry:Software
Since it can take considerable time to render a single 3D image, and most of that time is CPU compute time, many facilities using PC-based rendering systems have used large Winchester disks to which they send their final rendered images. This frees up the frame buffer for other work in the meantime. Later, when the animation is fully computed, the disk images can be quickly recalled and placed in the frame buffer, before being sent to videotape.
Industry:Software
Artistic effects added to a video production in order to enhance the production by creating drama, enhancing the mood or furthering the story. Special effects may vary from the limited addition of patterns or the mixing of several video images together, to sophisticated digital effects such as picture compression, page flipping, and three-dimensional effects. Special effects are usually created using SEGs such as those included in the Video Equalizer, Video TitleMaker 2000, and Digital Video Mixer.
Industry:Software
A complex function of frequency response (and correlated levels) relating the output to the input of the device as a function of frequency. A mathematical, graphical, tabular statement of the influence which a module has on a signal or action compared at input and at output terminals.
Industry:Software
a) Assemble mode. b) Edit that has a start time but no designated stop time.
Industry:Software
a) Procedure for solving a problem, coded into a form suitable for use by a computer. Frequently referred to as software. b) A collection of program elements. Program elements may be elementary streams. Program elements need not have any defined time base; those that do have a common time base and are intended for synchronized presentation.
c) A concatenation of one or more events under the control of a broadcaster, e.g., news show, entertainment show.
Industry:Software
A coded video sequence that commences with a sequence header and is followed by one or more groups of pictures and is ended by a sequence end code.
Sequential Color and Memory (Sequential Couleur avec Memoire) – a) French developed color encoding standard similar to PAL. The major differences between the two are that in SECAM the chroma is frequency modulated and the R'-Y' and B'-Y' signals are transmitted line sequentially.
The image format is 4:3 aspect ratio, 625 lines, 50 Hz and 6 MHz video bandwidth with a total 8 MHz of video channel width. b) A composite color standard based upon line-alternate B-Y and R-Y color-difference signals, frequency modulated upon a color subcarrier. All applications are in 625/50/2:1 systems.
Industry:Software
The tasks associated with setting up, maintaining, and troubleshooting a networked or stand-alone workstation or a network of workstations.
