An event during which an external input signal is routed directly to the specified output channel. See Logo Event. A measure of resolution often used in film and print media. There is often confusion when comparing film and video lines of resolution. In film, line pairs are measured as the number of line transitions measured per millimeter or per inch.
Vertical resolution is measured with horizontal lines.
Diagonal resolution is measured with diagonal lines. In video, lines of resolution are a measure of the maximum number of line transitions perceived over the entire length or width of the picture screen. Line Select A feature of a waveform monitor permitting selection of any video line within a video field for display. Linear Distortion A video system suffers from linear distortions when it cannot transfer all the amplitude and phase properties of a video signal faithfully at all frequencies. Typical linear distortions include peak overshoot, color smearing and brightness variances at edges of the display.
