Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
Coding that aims to reconstruct the waveform of the original (audio) signal as close as possible, independently of the material.
Includes linear PCM, differential PCM, adaptive differential PCM, sub-band coding, adaptive transform coding, etc.
Industry:Software
A pattern system effect that creates a design for revealing video using segments that have angular movement. This definition is our internal view, but not consistent within the industry.
Industry:Software
A term loosely used to describe the phenomenon of tape adhering to transport components such as heads or guides.
Industry:Software
On 1/4" wide tape, the arrangement by which only two channels of sound may be recorded, either as a stereo pair in one direction or as separate monophonic tracks (usually in opposite directions).
Industry:Software
The amount of digital information recorded along the length of a tape measured in bit per inch (bpi).
Industry:Software
Inaccurate digital representations of an analogue signal that occurs during the analog-to-digital signal processing. Typically, the digital interpretation of video resolution is limited through the digital sampling of the analogue video input signal.
Industry:Software
Information in the bit stream necessary for controlling the decoder.
Industry:Software
A device for displaying large, readable text on a partially transparent screen for video production. The teleprompter uses a monitor mounted under the camera lens, facing up, and a mirrored glass which reflects the monitor’s image toward the talent. Since the camera shoots through the mirrored glass and the mirrored glass is transparent to the camera, the talent can look directly into the camera lens as they read the script from the glass.
Industry:Software
A piece of test equipment which displays waveforms (analog video signals) at a horizontal and/or vertical rate. A specialised oscilloscope for evaluating television signals.
a) DC Restore - A circuit used in picture monitors and waveform monitors to clamp on point of the waveform to a fixed DC level. Typically the tip of the sync pulse or the back porch. This ensures the display does not move vertically with changes in the signal amplitude or average picture level (APL). The DC Restore speed can be set to SLOW or FAST DC. SLOW allows hums and other low-frequency distortions to be seen. FAST DC removes the effects of hum from the display so it will not interfere with other measurements.
b) AFC/Direct - This selection allows the waveform monitor’s horizontal sweep to trigger on each individual horizontal sync pulse (direct mode). This will allow the user to see any jitter that might be in the signal. Or the waveform monitor can trigger horizontally in the AFC mode which causes the horizontal sweep to trigger on the average value of the horizontal sync pulses. The AFC mode eliminates jitter.
