Replicated patterns (MULTI): This tiles the video space with multiple
copies of the pattern, with a maximum of 63 copies in both horizontal
and vertical directions. There are four different arrangements for the
tiling (1 to 4).
Pattern rotation (ROTATION): this rotates the pattern, in any of three
ways. These are shown in the following figure, along with the names of
the parameters used to control them.
Modulation (H MODULATION and V MODULATION): This
modulates the signal with a sine wave, applying a wavy effect either
vertically or horizontally.
Modulation is not available on the PGM/PST bank or downstream keyer.
To use modulation for an M/E wipe requires the optional BKDS-2070
Enhanced Wipe Generator Board to be installed.

through the specified
angle during the course
of the complete
transition.
Parameter: “Magnitude”
Rotating the pattern
through an angle (which
does not change as the
transition progresses)
Parameter: “Angle”
Rotating the pattern at
the specified angular
speed during the
transition.
Parameter: “Speed”
