Principal Functions
Video level and key level
The DVS-7250 I/O expansion system has 60 primary inputs, and among
these will be paired video (key fill) and key (key source) signals, including
signals from CGs, DMEs, and so on. A key signal is principally used only for
keying, and is not normally selected on a background bus. In this system, the
key signal can be associated with a particular video signal, and the two can be
handled together by a single cross-point button assignment, thus making
button assignments more efficient.
This setting is carried out in the XPT ASSIGN menu, and after assigning a
video and key signal pair to a cross-point button, it is also applied to the
“AUTO SELECT” function.
For details of the video level and key level settings, see the section “Carrying
out setup relating to assigning input signals to the cross-point buttons (XPT
ASSIGN menu)” (page 14-53).
The signal assigned to the “key level” of a particular cross-point button
number can only be selected on certain buses . The following describes the
buses on which key signals can be selected, and how to select a required key
signal on the buses.
Key source buses
Hold down the SPLIT button in the keyer control section, and select any key
signal on the KEY bus of this keyer.
AUX buses 1 to 28, EDIT PVW bus, FM1/FM2 buses, ME UTIL bus
Hold down the V/K button in the AUX bus control section, and select any
key signal. When selecting a key signal with the BKDS-7080/7081 (AUX
BUS REMOTE PANEL), similarly hold down the V/K button and select any
key signal.
Note
On the M/E BKGD-A/B buses and KEY FILL buses, the PGM/PST buses
and the DSK FILL buses, it is not possible to select the signal assigned to the
key level.
