6-9-8. DVE patterns and number of channels
Operation for transitions using DVE patterns is the same as for transitions using WIPE
patterns, though different patterns can be used by a multiple number of buses with the former.
However, the number of buses available for transitions simultaneously is restricted by the
DVE channels which can be used. Available patterns and number of channels are changed
by adding DVE options.

DVE Preset Pattern
The Hanabi HVS-3800 series switchers have two kinds of DVE options. Page turns and other
complicated 3D DVE preset patterns with WARP effects are available with the HVS-38DVE
3D option. Installation of option boards enables the operations shown in the table below.

* Pattern numbers 100 and up denote DVE patterns. The numbers of 3D patterns at the end of this
operation manual are indicated by shading.

The number of buses available for simultaneous DVE transitions is given in the table below.

* Two-channel patterns are preset patterns with numbers 200 and up. These patterns can be used only
with BKGD transitions. Only 1-channel preset patterns can be used with KEY transitions.
The number of buses available for the DVE is determined by the number of available layers
and number of channels for the patterns that are used. When using a standard DVE (one
channel) pattern, simultaneous DVE transitions are possible for background and key in SD
mode with the standard configuration. On the other hand, in SD mode with an optional
configuration, simultaneous DVE transition is available using a two-channel pattern for the
background or one-channel pattern for KEY1 and KEY2.
IMPORTANT
The number of buses available for the DVE is determined by the number of available layers
and number of channels for the patterns that are used. When using a standard DVE (one
channel) pattern, simultaneous DVE transitions are possible for background and KEY1 in
SD mode with the standard configuration. On the other hand, in SD mode with an optional
configuration, simultaneous DVE transition is available using a two-channel pattern for the
background or one-channel pattern for KEY1 and KEY2.
If all available DVE channels (layers) are used, the settings cannot be made and the button
will not light up when the DVE button on each bus or the DVE button in the NEXT
TRANSITION section is pressed. In this case, cancel another DVE setting, and then press
the button again.
