Figure 4-12. Genlock Menu (sample)
The Genlock Menu changes depending on the type of destination selected — widescreen
or single screen. Please note:
• For single screen destinations, the menu tells the ScreenPRO-II Controller
which type of analog genlock signal is connected to each ScreenPRO-II’s
Genlock BNC connector, and indicates the current setting of the selected
ScreenPRO-II’s
Termination Switch.
• For widescreen destinations, the menu tells the ScreenPRO-II Controller which
type of analog genlock signal is connected to BlendPRO-II’s
Genlock connector.
Remember that in this mode, each ScreenPRO-II’s
Genlock In connector must
be connected to BlendPRO-II’s
Widescreen Lock output — and not to an
external Genlock source. In Chapter 3, refer to the “
BlendPRO-II Widescreen
Lock Connections” section on page 77 for details.
The following functions are provided:
• Source — (applies to all types of destinations). This function sets the genlock
source, either
Black Burst, CSync or None.
• Type — (applies to all types of destinations). Displays the type of genlock:
~ When Source = None, Type = [Free-Run]
~ When Source = Black Burst, Type = [V Lock]
~ When Source = CSync, Type = [V Lock]
• Termination — (applies to single screen destinations only). This field indicates
the current setting of the selected ScreenPRO-II’s
Termination Switch.
Please note:
• If you elect to use external Genlock for single or widescreen configurations, PAL
or NTSC black burst or composite sync signals are recommended.
• In widescreen mode, you can optionally connect external Genlock to BlendPRO-
II’s
Genlock In connector — but not to the individual ScreenPRO-II units.
