3.21 INTERNAL DVx PROCESSOR !PRELIMINARY DESCRIPTION!
3.21.1 DVX GENERAL
The FX Processor is a powerful option for the DD35 switcher mainframe. It im-
proves the feature set and the value of DD35 significantly for all production pur-
poses. It supports the user of DD35 to increase the efficiency of productions and
investments.
The FX Processor provides internal DVx (DVE) and huge video storage capabilities
to the DD35 user. The DVE is mainly designed to cover the basic effects that are
widely used in day to day productions. Integration of the DVx into the switcher
avoids the requirement of additional space for installation, additional power supply
and additional cabling. No inputs or Aux buses are required to feed the DVx. This
frees all the I/O of the switcher for other video signals.
Close integration of DVx control into the user interface of the switcher gives more
creative power to the operator and optimizes the efficiency of the operation per-
sonal.
FX Processor functions:
D
DVx
The FX Processor board provides 4 channels of DVx with linear effects in 3D
space. Every channel handles video or key signals. Sizing, Positioning and Ro-
tation in all 3 axis can be performed and perspective representation of the
images.
A combiner function combines the DVx channels on the board to not block the
keyers or transition means on the DD35 M/E. The combiner also provides Z–in-
tersection for the DVx channels.
All DVx channels can be controlled independently or a any number of channels
can be controlled together through a global control channel
Examples for applications are picture in picture, over the shoulder boxes, cu-
bes, and more.
D
RAM Recorder
The FX Processor also includes 4 channels of RAM Recorder. Each channel
can store 8 sec of uncompressed video together with embedded audio data.
The 4 channels can also be combined to form one channel of 32 sec.
The RAM Recorder can be used as large still store, for trailers and intros, an-
imated logos, and more.
D
Key Shadow
The FX Processor includes 3 key stores for generation of far shadows. The 3
key shadow stores are dedicated to M/E1 to M/E3.
For many applications it will make the need for an external DVE obsolete or enable
it to be used for more sophisticated true 3D effects.
