Configuration (Iss. 04) • 20
Standard/VTR Mode
This menu enables the module to convert either broadcast quality or
non-broadcast quality analog input signals independently, selectable according
to the level of the video quality to be received. The level of conversion quality
required for a non-broadcast VTR signal is different than a broadcast signal. In
the default state, Standard mode, a 3-line adaptive filter is employed to assure
the highest quality conversion to SDI video output standards. In VTR mode,
however, the 3-line adaptive filter is disabled and a notch filter is used instead.
Video Level
Use this menu to adjust the video level of the SDI signal to match the white level
of the incoming video. This setting also affects the black video level menu so it
will be necessary to go back and forth between these two adjustments to get both
black and white levels set. This menu has a 2-button quick default to unity
(default). Press both up and down buttons at the same time and hold for three
seconds. Since the white and black levels are linked together, defaulting the
white level will automatically default the black level as well.
Black Level Offset
Use this menu to adjust the level of the SDI signal to match the incoming video
black level. This setting is also affected by changes in the Video Level menu
(see above), so it will be necessary to go back and forth between these two
adjustments to get both black and white levels set. This menu has a 2-button
quick default to unity (default). Press both up and down buttons at the same time
and hold for three seconds to jump to unity.
Chroma Level
Use this menu to adjust the video chroma level of the SDI signal to match the
incoming video color levels. This setting and the U-Gain setting are adjusted
together for best results using an SDI vector scope. This menu has a 2-button
quick default to unity (default). Press both up and down buttons at the same time
and hold for three seconds.
Hue
Use this menu to adjust the video Hue angle of the SDI signal to match the
incoming video color levels. This menu is disabled for component formats. This
menu has a 2-button quick default to unity (default). Just press both up and
down buttons at the same time and hold for three seconds.
U-Gain
Use this menu to adjust the gain in the U component of the SDI signal to match
that expected for the incoming video color levels. This setting and the Chroma
setting are adjusted together for best results using an SDI vector scope. This
menu has a 2-button quick default to unity (default). Press both up and down
buttons at the same time and hold for three seconds.
