Introduction
In general, any video switcher receives multiple video inputs, performs
signal processing on selected input signals, and then outputs the processed
video. Efficient real time switcher operation is essential for live production,
and can save valuable time in post production environments as well.
Several innovative concepts are employed in the Zodiak Digital Production
Switcher to enhance its operational speed and flexibility. Understanding
these concepts, as well as basic switcher fundamentals, will help you take
full advantage of the exceptional power of the Zodiak system.
Zodiak System Configuration Overview
The Zodiak Digital Production Switcher is designed for operational flexi-
bility, and can be configured to fit various applications. Different Zodiak
systems can have different capabilities, or the same Zodiak system can be
re-configured to have different capabilities at different times.
The way a Zodiak Digital Production Switcher is wired into your facility
affects the Zodiak system’s capabilities. For example, the number and
types of sources physically connected to the system obviously determines
what video the system can handle. However, because Zodiak system
video/key inputs and Aux Bus outputs can be configured, once video
cables are physically connected they need not be moved. Configuration set-
tings also control many other capabilities that affect Zodiak system
behavior.
