• The above signal selection operation can only be carried out from a
switcher control panel (BKDS-7011/7012/7021/7022/7023) or editor
which can be directly connected to both the DVS-7000A and DMK-
7000 processors. It cannot be carried out from other controllers (such as
an M/E remote panel using the BKDS-2010).
• Switching the preview output for a switcher M/E bank or DMK-7000's
downstream keyer: Select PVW, KEY or CLEAN as the preview output of
a switcher M/E bank or DMK-7000's downstream keyer.
• Defining the PVW output of a switcher M/E bank or DMK-7000's
downstream keyer:
For M/E banks 1 to 3: Select L-PVW (look-ahead preview) or K-PVW
(key preview).
To carry out K-PVW in an M/E block, you require the optional
BKDS-7280 M/E PVW board.
For DSK1 to 4:
Option
• When the DMK-7000's keyer configuration is set to CASCAD
• When the DMK-7000's keyer configuration is set to PARA
About L-PVW, K-PVW, and F-PVW
• L-PVW (look-ahead preview)
The L-PVW output consists of the output video after a transition
executed according to the settings made with the next transition
selection buttons in the transition control section has been applied.
For the downstream keyers (DSK1 to DSK4), L-PVW can be selected
only for a 3.5-M/E system with the keyer configuration set to CASCAD
(cascade).
• K-PVW (key preview)
For the M/E-1 to M/E-3 banks, the K-PVW output consists of
background video in which both key 1 and key 2 have been inserted.
For the downstream keyers (DSK1 to DSK4), the K-PVW output
consists of background video in which the key has been inserted. If the
keyer configuration is set to CASCAD (cascade), the program output of
the preceding downstream keyer is used as the background video.
(cascade) in the SYSTEM CONFIGURATION menu, select L-
PVW, K-PVW, or F-PVW (full-key preview).
(parallel), INDPND (independent), or DUAL (dual cascade) in the
SYSTEM CONFIGURATION menu, K-PVW is selected
automatically.
