1. The generator treats double-clocking and pixel repetition as two totally separate items.
NCPP controls the number of clocks per pixel, while NPPP controls pixel repetition factor.
All library formats set pixel repetition factor NPPP to zero (i.e. OFF) by default. Dou-
ble-clocking and pixel repetition cannot be applied simultaneously due to AVI:RP field
constraints. Therefore, double-clocked formats do not support pixel repetition. Pixel rep-
etition is only applicable to the "4x" formats, where HRES remains at 2880-pixels as the
pixel repetition factor NPPP is varied between 1 and 10 - thereby varying the effective
resolution.
2. Double-clocked formats have the same horizontal resolution as single-clocked formats -
the horizontal active (as we define it), is not doubled in the double-clocked case. Some
formats are distinguished by a horizontal active that is 4-times the normal value of 720.
Here, pixel repetition may be applied, by a special "PixelRep" test image, after the format
has loaded. The "PixelRep" test image allows the number of pixels-per-pixel (NPPP) to
be varied and an image with repeated pixels to be rendered for test purposes.
3. Some formats are distinguished by having a slightly different vertical line total.
