System Parameters Menu
The System Parameters Menu allows you to set the video
standard (internal black level), to select the matte generator
chroma limiting algorithm, and to set the system clock.
The System Parameters Menu selections are as follows:
INTERNAL BLACK LVL — Selects either 7.5 IRE or 0 IRE, which sets
the video standard (internal black level) for operation on the
NTSC standard used in the U.S.A. (Black = 7.5 IRE) or the NTSC
standard used in Japan (Black = 0 IRE).
FIELD DOM — Allows you to specify on which field “set” changes
made during the vertical interval will take effect.
NONE — Selection changes become effective at the beginning
of the next field, immediately after the functions have been
changed).
