Functional Overview

Video Signal Flow
The basic system architecture (Figure 7) of the KayakDD-1 system has been designed
for operational flexibility. For example, all the outputs from the M/E are routed back to
the video crosspoint matrix, making all these signals accessible to the entire system.
The 16 video inputs to the Video Processor frame can be mapped to any of the 16
crosspoint buttons. Internally generated white and three backgrounds are also
available sources, as are the four RAM Recorder outputs. This source-to-button
mapping is done through the touch screen menu and can be stored as a user profile
for any number of individual users. Button mapping is the same on all buses.
The system has a full M/Es with PGM/PST. Internally generated black and two
backgrounds are also available sources, as are the four Still Store outputs.
The selected video on each bus is deserialized and reclocked before entering the
video processing circuitry. Video processing is available for each separate M/E
background, Key, and Utility bus, providing built-in solarization, posterization and
mosaic effects. In addition, contrast, brightness, and hue can be adjusted on a bus-by-
bus basis.
The M/E has four full-function keyers with optional internal Digital Picture Manipulators
effects. Each keyer has access to its own wipe generator as well as a pair of standard
floating chroma keyers which may be assigned to any keyers in the system. Two
complex wipe generators serve each M/E, providing a wide range of wipe choices with
modulation, rotation and multiplication of each one. Wipe signals can also be taken
from the Utility bus on the M/E.
The outputs from M/E Program and Preview are fed to dedicated BNCs and sent back
to the crosspoint circuitry for the Auxiliary buses as well as the clean feed output.
Ten Aux buses are available in the M/E system. The Aux bus outputs can be utilized in
a number of ways. Every Aux bus provides individually adjustable safe area and
crosshair (center cross) capability.
