This section presents a general description of the Grass Valley
Products Model 2200-2 Production Component Digital Switching
Systems.
The Control Panel and Signal Processor descriptions provide a
basic knowledge of the Model 2200 basic architecture.
Basic Architecture
The Model 2200 is a component digital switcher. It can manipulate
CCIR 601 serial component digital and analog component video
and key signals through the use of 10-bit digital processing. An
Analog Chroma Keyer Input Module is also available.
The Model 2200-2 provides two full function mix/effects
subsystems. Up to 32 serial digital inputs which can be mapped to
switcher crosspoint buttons and used as video and/or key
sources. Internal sources are also available, such as Black, Masks,
Color Bars, and Background.
Effects animation functionality may be used to build and run a
sequence of effects. Effects are stored in E-MEM registers as a list
of “keyframes” (see the User Guide), for a definition of
Keyframes). The E-MEM register operations are used to learn,
recall, copy, and link effect registers.
The layout of the Control Panel is logically structured for efficient
control of video signals.The Menu Display Subpanel allows quick
changes to switcher system parameters.
