Masks

A mask is a technique in which a pattern is combined with the key source to block out unwanted portions of the key source.

Three types of masks are available, box masks, pattern masks, and utility bus masks. All key types can be masked.

  • Box Mask — uses a simple box shape to mask out a portion of the key.
  • Pattern Mask — uses a pattern from the pattern generator to mask out a portion of the key.
  • Utility Bus Mask — uses a video source selected on utility bus one to mask out a portion of the key.
