Grass Valley DD35 Family v.3.1.5 - Manual (Page 86)

2. Panel Operation DD35 Production Switcher
2 – 52 Operating Instructions – Rev. 16 / 10.2001
The three-channel downstream keyer enables the user to insert captions, figures
or characters using Luminance, Linear or Chroma Key (option) into the program
picture which have priority over the other picture components.
The functions are identical to those in the M/E1, M/E2 and M/E3 keyer panels.
The buttons DSK1 through DSK6 are used for delegation. DSK1, DSK2 and DSK3
are internal and DSK4 , DSK5 and DSK6 are optional external keyer boxes, e.g.
Ross CDK104 or Oxtel EasyKey.
Two control modes are available to cope with different control concepts. When
leaving the factory, the control panel is equipped with the button inlays for mode
1. The inlays for mode 2 and further inlays are included in the switcher delivery and
can easily exchanged.
If the 2nd Func button is not pressed, Cut and Auto can be operated from
DSK1...6.
If the 2nd Func button is pressed, TransDur and Couple are operated from
DSK1...6.
2nd Func button toggles between DSK1...3 (Cut, Auto, TransDur, Coupled) and
DSK4...6 (Cut, Auto, TransDur, Coupled).
It is possible to toggle between the two modes by simultaneously pressing the two
arrow buttons in the Matte panel and the 2nd Func button in the DSK panel.
2.8.1 DOWNSTREAM KEYER TRANSITION
The downstream keyers may be faded in the same way as the keyers in the M/Es
by selection and actuation in the Transition panel of the downstream keyer.
It is also possible to fade the downstream keyers independently from the next-tran-
sition selection.
