Grass Valley DD35 Family v.3.1.5 - Manual (Page 52)

2. Panel Operation DD35 Production Switcher
2 – 18 Operating Instructions – Rev. 16 / 10.2001
The pre-processed signals can be selected on
D
logical DVE buses (see also section: DVE Integration)
D
any AUX bus (it is an application setup whether the AUX bus takes the pro-
cessed video or the processed key)
D
Montage Processor
(MPR1 always uses the video and MPR2 always uses the key)
D
VideoStore (always the video)
The pre-processed signals cannot be selected on the Mask buses and on the exter-
nal AUX buses.To select a specific signal:
D
Press and hold down the respective M/E button
D
Press the button of the signal to select
D
Release the M/E button
Since each stage can send only one out of the four or five possible signals, there
might be a conflict. For example:
D
AUX1 has selected Key1 of M/E 1.
When a selection for AUX2 is made to send Key2 of M/E 1, there is a conflict,
because only either Key1 or Key2 can be sent.
D
To resolve this conflict, the DD35 switcher uses the principle ”the last one wins”.
D
In this case, Key2 of M/E 1 is then selected on both buses AUX1 and AUX2.
