Histogram
A statistical analysis of all the luminance values in a frame or a band
lines pre-selected with Line Select. The average weighted Histogram
display is useful for identifying bad coding with missing values, super
black level problems and APL characteristics. In terms of 8 bit coding
there should not be a high percentage below the value 16 (super black)
or above 235 (super-white).
RGB Parade
With a component source such as SDI or DV, Vidscope matrixes the
signal according the either Rec.601 or 709 (see page Error! Bookmark
not defined.) to produce RGB components. These are fed to the
Preview Monitor and the RGB waveform display.
The RGB display is related to the line selection used. There are 3
modes of display according to the settings on the Stack and
Superimpose option buttons that are revealed in the RGB mode.
