Masking
To mask unwanted portions or defects in the key or background, there are
two masks you can use: the main mask and the subsidiary mask.
• The main mask uses as source signal the box generator built into each
keyer, or a dedicated mask pattern generator.
• The subsidiary mask uses as source signal a wipe generator from an M/E
bank or the PGM/PST bank or a signal selected on the utility bus.
You can use the main mask and subsidiary mask independently, or you can
use both simultaneously.
Using the main mask
By way of example, the following procedure uses the main mask on keyer 1
of the M/E-1 bank.
