is used to remove captioning from line 21.
Note: The captions are

ed from the main, high quality, output only. This will allow the monitoring of
upstream captioning on the
monitoring output
even when it is not desirable to have them passed
downstream on the program video.
8.11.3. Composite Display Mode
If monochrome operation is desired on the composite output, colour may be turned off with this
parameter.
8.11.4. Video Level
This parameter allows the user to adjust the output level of the analog video (including sync). When set to
0, the nominal output video level will be 140 IRE.
Warning: The brightness and contrast controls will also affect video level. Set this control by measuring
sync level rather than video level. After calibrating the brightness and contrast, come back to this control
and verify the video level.
8.11.5. Hue
This parameter allows the user to adjust the Hue of the analog video in steps of 0.5 degrees.
8.11.6. Saturation
This parameter allows the user to adjust the saturation level of the analog video.
8.11.7. Contrast
This parameter allows the user to adjust the contrast (white level) of the analog video.
8.11.8. Brightness
This parameter allows the user to adjust the brightness (black level) of the analog video.
8.11.9. H Blanking
When set to
Narrow
, the H blanking will be 10.7µsec wide. When set to
Wide
, the H blanking will be
11.2µsec.
8.11.10.
VBI Processing
The Vertical Blanking Interval may be passed to the component outputs or may be blanked (removed) to
not interfere with display of the image.
8.11.11.
Y Filter Selection
The Y channel may be filtered with a standard composite filter or may be wideband. When
Wide
Bandwidth
is selected, the following control allows the frequency response to be adjusted.
