Section 1 — System Overview
Video Processor Frame
The Krystal Video Processor frame contains modules that receive the
incoming video and key signals, performs the actual video manipulations,
and outputs the processed video. On single channel Krystal systems the
Video Processor frame also holds the Effect Manager modules that commu-
nicate with the Control Panel and direct the video processing activity. On
multi-channel systems some of these communications and control modules
are located in the System Controller frame.
The Video Processor frame is a 13 rack unit frame that mounts in a standard
19-inch equipment rack. The frame holds large modules installed from the
front (
Figure 1-9 ), and smaller I/O modules installed from the back
( Figure 1-10 ). Some of the front loaded modules are options, and some
modules may have standard or optional mezzanines (daughter boards).
