a) A form of low-frequency interference, appearing as a narrow horizontal bar moving vertically through the picture. This is also observed on an oscilloscope at field or frame rate as an extraneous voltage pip moving along the signal at approximately reference black level. b) Slang for visual error, i.e., dropout on tape, spikes at switcher pattern boundaries.
Patterns that jump off screen or any other aberration. c) Slang for a fault in data transmission or other error that does not cause a total lock up.
Industry:Software
A term used to define the voltage/time function of a single DAC step until the output video level has settled to within ±1 LSB of the final value. Glitches are apt to appear in output video as the input to the DAC changes from: 0111 1111 to 1 000 0000.
Industry:Software
A separate channel that allows additional rotations to be superimposed on an image and, in 3D systems, “motion on motion” in an effect.
Industry:Software
A data set with all data essence or metadata elements defined in the relevant data essence standard or Dynamic Metadata Dictionary.
