Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
Polygons meshed together to create closed volumes. It is a compact set of contiguous points in three-dimensional space.
Industry:Software
A four-word reference signal used in serial composite digital systems to synchronize the conversion of serial data back to parallel.
Industry:Software
Zig-zag scan of quantized DCT coefficient matrix. This gives an efficient run length coding (RLC).
Industry:Software
The line of push button switches on the control panel which select and indicate the preview output, and represents the next video that will appear when the DSK fader is pulled. It can also select and indicate key sources to other keyers due to the fact that it is a “split” bus. That is, reentries can be selected for the next video as well as bus inputs for a key source, both at the same time. This type of bus is exclusive to 4100 series switchers.
Industry:Software
The intrinsic difficulty of the image sequence to code. For example, the “talking head” video sequences which occurs often in video conferencing applications are much easier to code than an actionfilled movie for entertainment applications.
Industry:Software
a) Abbreviation for synchronization. Usually refers to the synchronization pulses necessary to coordinate the operation of several interconnected video components. When the components are properly synchronized, they are said to be “in sync.” b) Signals which control the sweep of the electron beam across the face of the display. The horizontal sync, or HSYNC for short, tells the display where to put the picture in the left-toright dimension, while the vertical sync (VSYNC) tells the display where to put the picture from top-to-bottom. c) The portion of an encoded video signal which occurs during blanking and is used to synchronize the operation of cameras, monitors, and other equipment. Horizontal sync occurs within the blanking period in each horizontal scanning line, and vertical sync occurs within the vertical blanking period.
Industry:Software
a) Time-code information stored on specific scan lines during the vertical blanking interval. A popular method for recording time code onto videotape. A time-code address for each video frame is inserted in the vertical interval (the vertical blanking retrace period) of the video signal, where it is invisible on-screen yet easily retrieved, even when a helical scanning VCR is in pause mode. The most common form of VITC is SMPTE-VITC. The Thumbs Up editor supports SMPTE-VITC (as well as RC time code). b) Time code stored in the vertical interval of the video signal. Has the advantage of being readable by a VTR in still or jog. Multiple lines of VITC can be added to the signal allowing the encoding of more information than can be stored in normal LTC.
Industry:Software
The amplitude (voltage) difference between the most positive and the most negative excursions (peaks) of an electrical signal.
Industry:Software
To listen to one mike or track of a tape without listening to the others through the use of a solo button.
