Frame Store Module (064814)
The Frame Store function allows storage and retrieval of images at a 10-bit
resolution. Two 10-bit channels, video and key, enter the module from the Mixer
Interface Module. The signals are processed on the module according to the
controls on the Frame Store subpanel, delayed and sent to the Frame Store output
on the optional Serial Output Module and to the reentry crosspoints. The Frame
Store Mezzanine Board mounts on the Frame Store Module.
Microprocessor control of the module is from a resident microprocessor on the
module and the HOS processor.
