Section 4— Switcher Operations
Starting Conditions
The switcher, and any connected external devices, should be in a
“known,” or User Default state before beginning any of these
tasks. Select “GVG Defaults” on the Config/User Prefs/Define
Defaults Menu, if you are not sure what setups you need.
Switcher Hardware Setup
The following requirements are needed in order to complete the
procedures in this guide.
■ Two separate video sources. These can be any still or moving
video sources and will be referred to as Source 1 and Source 2.
■ A Character Generator set up with three lines of text available
with a key signal. This will be referred to as the Title 1.
■ A Digital Video effects source (such as Kaleidoscope, Krystal
or DPM-700) with key, to be referred to as DPM. Set up with
a box with soft white borders and positioned in the top right
of the screen.
■ Two video monitors - 1 for Program (on-air) and 1 for Preview.
The preview monitor is useful if you have the Look Ahead
Preview option.
■ These video sources should be mapped to known switcher
crosspoint buttons along with the internal Black and the
Background signals. If this has not been done refer to the
switcher configuration information in
Software Setup in
Section 2 of this guide.
