About Key Chaining
About Key Chaining
Key Chaining allows you to chain keys to coordinate their keyer states (on and off ) on a
single M/E or from one M/E to another. There are 15 Key Chains available in a GV Switcher
System. All keys in a chain transition on and off together. Key Chaining is performed in the
User Setup, Suite Prefs, Key Chaining menu.
Some uses for Key Chaining are:
• Keyers within an M/E for language or Ident separations of clean feeds,
• Aspect ratio-specific graphics across more than one M/E, or
• Advertising graphics on bus-linked M/Es which already substitute background pictures.
In the Key Chaining menu, you can configure which keyers are chained together in each
chain. The following rules apply:
• Each keyer may not be in more than one Key Chain.
• All keyers in a Key Chain will be equal in command priority.
Key Chaining is part of the GV Switcher configuration and saved as part of File Ops, Suite
Prefs. A layer of load granularity (
Key Chaining button) has been added to this menu.
Keyers are controlled from the Transition Module on the GV Switcher Control Panel. They
can be cut on/off or transitioned on/off using the dedicated Key Cut and Auto buttons. Key
chaining allows for a single button push to transition all the keys in the chain. A single keyer
selection in the Next-Transition area will similarly cause the other keys in the chain to be
selected. Then a single push of the
Auto button or movement of the Lever Arm will cause all
of the keys in the chain to transition on one or more M/Es simultaneously.
Creating a Key Chain
To create a Key Chain or chains in a single M/E, simply select a Chain parameter data pad
(Chain 1, Chain 2, etc.) to select it (turns blue), and select the keys you wish to add to the
chain. Select another Chain parameter data pad and repeat the process (for the same M/E in
this case).
The Chain parameter data pads display each M/E and either dashes (if empty) or Keys 1-4/6
if keys are enabled for that M/E in the chain.
