Section 1 — System Overview
Extender Modules
Two module extenders are supplied for use in troubleshooting Signal Processor
Frame modules to the module level only. The longer extender is for the modules
in front bays A (top) and B (bottom). The shorter one is for the input and output
modules in rear bays C (top) and D (bottom). These extenders allow you to extend
a circuit module beyond the depth of the signal frame, so that components are
readily accessible for testing and maintenance.
Frame Store Option
The Frame Store option allows storage and retrieval of images at a resolution of 10
bits. Frame Store is source oriented in that its inputs are fed with an AUX/effects
send bus (Aux 4) and the outputs are available as primary inputs to the crosspoint
matrix. Frame Store can be connected in the effects send loops. Frame Store
features are listed below:
■
Video hue functions include rotate or blur (mutually exclusive).
■
Frame Store functions can be controlled by E-MEM.
■
Real-time video bit map effects include Mosaic, Posterize, Solarize, Color
modulate, Contrast stretching or Hue modulate and subpixel repositioning.
Effects can be applied to frozen or live video.
■
Write after read capability allowing layering of stills in a recursive manner.
(i.e., frame store could receive output from an M/E that is using the frame
store as one of its inputs).
■
Ability to provide a real-time drop shadow on a key that can be positioned
anywhere in the raster. Shadow can be blurred and opacity adjusted
independently of Video and Key framestores.
■
Frame Store Video and Key may be keyed on top of a background source.
■
Four pages of two-field images may be captured at 525 line rate (3 pages at 625
line).
■
If Field 1 or Field 2 are frozen, interpolation modes can be applied.
■
Independently adjustable crop on video and/or key.
