Configuration Menu
FIELD 1 or FIELD 2 — Changes become effective at the
beginning of the selected field. If a change takes place prior to
the other field, it will be delayed by one field so that it also
becomes effective at the beginning of the selected field. This
way, all changes are synchronized to take place at the
beginning of the same field.
MATTE GEN LIM — Selects the desired matte generator
chroma limiting algorithm. The selections are as follows:
XMITABL — Prevents the total signal (luminance and
chrominance) from exceeding the NTSC transmission
standard.
VALID RGB — Limits colors to those which generate red,
green, and blue values within the 0 to 100% range.
BOTH — Selects a valid RGB color limiter that also prevents
the encoded signal envelope from exceeding NTSC
transmission level. (This is the system default mode.)
NONE — Turns off all algorithm methods for matte generator
limiting.
START HORIZONTAL BLANKING — Adjusts the start of H blanking
over a range of -16.0 clocks to +16.0 clocks. Default is 0.0 clocks.
END HORIZONTAL BLANKING — Adjusts the end of H blanking
over a range of -16.0 clocks to +16.0 clocks. Default value is 0.0
clocks.
SUPERBLACK OUTPUT — Adjusts the superblack output level
over a range of -20.0 IRE to +7.5 IRE for U.S.A. NTSC, or -20.0 IRE
to 0.0 IRE for the Japanese NTSC.
H-BLANKING DEFAULT — Resets the horizontal blanking start and
end values to GVG default settings (0.0 clocks).
ASPECT RATIO — Selects either 4x3 or 16x9 Aspect ratio for those
installations equiped for this format.
SET CLOCK> — Displays the Set Clock Menu, which allows you to
set the date and time for the system.
