3.4 Digital ProcAmp Functions
These functions allow the adjustment of different parameters for both the analog
and digital video outputs. Y, Cb and Cr gains may be adjusted individually or
simultaneously; the black level, hue and saturation may also be controlled.
Additional controls are also provided for horizontal picture positioning and cable
equalization.
3.4.1 Y, Cb, Cr Gain Adjustments
Individual components of the video output may be adjusted by performing the
following steps. Each component has an absolute gain range of –800 of +800,
with unity gain (the default value) being set at 0. To change the value more
quickly, depress and hold the “+” or “–“ pushbutton.
1. Press SELECT to enter the menu.
PROC
is displayed..
2. Press SELECT to enter the ProcAmp menu.
Y
is displayed. To adjust the Cb
or Cr component press the “+” push-button until
Cb
or
Cr
is displayed.
3. Press SELECT to enable the selected gain menu. The current value is
displayed.
4. Use the “+” or “–“ push-button to set the required gain level for the selected
component. Press the “+“ and “–“ push-buttons simultaneously to set the
selected gain level to unity.
5. Press SELECT to store the new gain level for the selected component.
6. Press ESC to return to
PROC
.
7. To return to normal mode, press ESC.
3.4.2 Overall Gain Adjustment
The overall gain applies to the Y, Cb and Cr gains simultaneously. Note that
relative gain setting differences are maintained between the individual
components: as an example, if Y is set to 100, Cb to 50 and Cr to 0, an overall
gain adjustment of 10 will result in Y=110, Cb=60 and Cr=10. Values range from –
800 to +800, unity gain (the default value) being set at 0. Perform the following
steps to adjust overall gain:
1. Press SELECT to enter the menu.
PROC
is displayed..
2. Press SELECT to enter the ProcAmp menu.
Y
is displayed. Depress the “+”
push-button until
ALL
is displayed.
3. Press SELECT to enable the overall gain menu. The current value is
displayed.
4. Use the “+” or “–“ push-button to set the required overall gain. Press the “+ “
and “–“ push-buttons simultaneously to set the overall gain to unity.
5. Press SELECT to store the new overall gain.
6. Press ESC to return to
PROC
.
7. To return to normal mode, press ESC.
3.4.3 Saturation Adjustment
The saturation adjustment (chroma gain) affects both the Cb and Cr gains
simultaneously. Note that relative gain setting differences are maintained between
the Cb and Cr components: as an example, if Cb is set to 100 and Cr to 0, an
overall gain adjustment of 10 will result in Cb=110 and Cr=10. Values range from
