Grass Valley DD35 Family v.3.1.5 - Manual (Page 20)

1. General DD35 Production Switcher
1 – 6 Operating Instructions – Rev. 16 / 10.2001
1.1.7 OUTPUT PROCESSOR (GENERAL)
D
One Output Processor (see below) is mandatory
D
AUX buses (e.g. for DVE Video+Key, Aux-PVW) with auto-follow for various
preview functions.
D
On Aux buses 1–5, the automatic internal line synchronization can be switched
off in order to allow external device loops (e.g. color correction ...). A feedback
of processed signals into the inputs works without additional 2V synchroniza-
tion, provided their delay is some micro seconds only.
1.1.7.1 Output Processor RY 2154 with 15 Aux Busses (1–15)
D
Output Processor with 15 Aux Busses
1.1.7.2 Output Processor RY 2153 with 10 Aux Busses (1–10)
D
Output Processor with 10 Aux Busses
1.1.7.3 Output Processor RY 2155 with 5 Aux Busses (1–5)
D
Output Processor with 5 Aux Busses
1.1.7.4 Options for Output Processor
D
Texture / Matte Store RC 2181
4:0:0 Image store for freezing textures (derived from the wipe generator), re-
spectively key signals for modulating the gradient between the two mattes of
the color background.
The Wash-Key signal can be determined with a wipe generator or from a keyer.
The option does not store the actual colors, but the transition information be-
tween them; i.e. with a stored color transition (via wipe), both mattes still can
be changed. Store content lost as soon as mixer is switched off.
Store gets inputs signals from M/E 1.
D
Image Store (frame grabber) RC 2182
4:2:2 store for freezing one full frame. Frame, Field 1/2 select possible for sepa-
rate save as well as readout. This allows for 2 separate videos to be stored with
half vertical resolution. Horizontally the store contents can be shifted +/– 128
pixel in +/– 64 steps. ”Grab” function implemented for photo snapshot function-
ality on video.
The input of the store can access all primary sources, as well as the internal
signals PVW, PGM and Clean Feed.
The image store content gets lost as soon as the mixer is switched off.
