Refers to a cathode-ray tube and its associated circuits, arranged to view a television picture.

In the practical sense, resolution is usually judged by imaging test targets bearing sets of spaced black-and-white lines in a square-wave pattern, and determining the minimum spacing for which the lines are distinguishable in the resultant image. With instrumentation readout, resolution target charts are less ambiguous and more useful if they bear sets of spaced “black” and “white” lines sinewave modulated in density, rather than square-wave modulated. Whereas square-wave targets introduce a Fourier series of higher frequencies, sinewave targets limit the analysis to a single frequency for each line set. Quantitative measurement of the modulations provides convenient determination of the transfer function.
Industry:Software
a) The electrical transfer of a signal, message, or other form of intelligence from one location to another. b) The transfer of a video waveform from point to point by conductive cable or fiber.
Industry:Software
a) Sampling of a line of repetitive video signal in such a way that samples in each line are in the same horizontal position.
b) Picture sampling arranged in horizontal rows and vertical columns.
Industry:Software
A set of elementary streams offered to the user as a program.
They are related by a common synchronization. They are made of different data, i.e., video, audio, subtitles, other data.
Industry:Software
The standard file format for highresolution bit-mapped graphics, especially from scanners.
Industry:Software
The area of a video signal which will be visible on a receiving monitor. Often denoted by marks within the viewfinder of the video camera.
