Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
This type of display shows the phase relationship of the colour oscillator and the 50% point on the leading edge of the horizontal sync pulse. The phase of these two can be within 0 to 360 degrees of each other. In the example below, there is a 12 degree phase difference between the two.
Industry:Software
A lack of vertical synchronisation which causes the picture as observed on the picture monitor to move upward or downward.
Industry:Software
A B/W video output available as an option on AVC series switchers that provides display of all switcher adjustments, pattern menus, and diagnostic tools.
Industry:Software
Term used for a type of camera movement where the camera actually moves left to right (or vice versa) across a scene.
Industry:Software
A 13-bit code in the transport packet header.
PID 0 indicates that the packet contains a PAT PID. PID 1 indicates a packet that contains CAT. The PID 8191 (all 1s) indicates null (stuffing) packets.
All packets belonging to the same elementary stream have the same PID.
Industry:Software
Distortion resulting from the asymmetry of sidebands used in vestigial-sideband television transmission. Quadrature distortion appears when detection is used, but can be eliminated by using a synchronous demodulator.
Industry:Software
The 2D function that moves or sizes the image on the 2D plane, which is “Target Space.” In 3D systems, Target is used to move an image without perspective and to “fine tune” an effect.
Industry:Software
This video effect is related to morphing except that a warp consists of transforming one video image into one of a completely different type. For example, a scorebox might be twisted on and off a screen containing video action. Some examples of video transitions include flyons/ offs, slide ons/offs, zoom in or out to/from a pinpoint, shattered glass transition, pixelization where on screen explodes into thousands of pixels, and fades out at a controlled rate.
Industry:Software
Refers to the polarity of the black portion of the picture signal with respect to the white portion of the picture signal.
For example, in a “black negative” picture, the potential corresponding to the black areas of the picture is negative with respect to the potential corresponding to the white areas of the picture; in a “black positive” picture, the potential corresponding to the black areas of the picture is positive.
The signal as observed at the broadcasters’ master control rooms and telephone company television operating centres is “black negative.”
Industry:Software
The effect that occurs when a piece of equipment can no longer process the frequency which is being fed into it (a reduction in amplitude with an increase of frequency).
