7735CEM Composite Encoder with Monitoring
Closed captioning has been defined to NOT have a 7.5 IRE pedestal, but
it is placed on the first active line of video where there may be a pedestal.
The upstream closed captioning encoder should not have generated a
setup pedestal. When encoding composite video with properly keyed
captioning, a pedestal must not be generated.
This control, when set to Off, will not create the 7.5 IRE pedestal on line
21. This is the default state for properly generated captioning.
When set to On, the 7.5 IRE pedestal will be generated on line 21. Use
this state when there are no input captions.
Note: The On condition will only take effect if the NTSC Setup Pedestal
control is set to On.
Blank is used to remove captioning from line 21.
Note: The captions are Blanked 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.
If monochrome operation is desired on the composite output, colour may
be turned off with this control.
This control 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.
