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.

Two types of masks are available, Box masks and Pattern 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
Note: Pattern masks are not supported in UHDTV1.
