KayakDD - Digital Production Switcher
In the upper part of Figure below, the video component of source 2 in the figure has
been selected on the key fill bus and becomes the key fill signal for subsequent keying.
The key component of source 2 selected on the key cut bus becomes the key cut
signal for keying. The lower part of Figure 4 below shows how the same source
(source 4) can be selected for both the key fill and key cut signals.

2.6.6 Shifted Sources
An operator may need to quickly access many sources during a production. However,
a control panel has size limitations, since all the source selection buttons must remain
within reach. The KayakDD system provides shifted buttons to allow access to more
input sources from the control panel.
For exemple, on the KayakDD-1 system, up to 28 sources can be mapped at one time,
14 to the unshifted source selection, and 14 to the shifted buttons. A dedicated
Shift
button is provided as the farthest right crosspoint button (Crosspoint 15) for every bus.
Two shift modes are available: Normal and Latched.
In Normal mode, shifted or unshifted status of the bus is indicated by the state of the
Shift button light. Holding down the Shift button while pressing a source button always
selects the shifted source for that bus.
The
Shift button will light when the row of buttons to its left are shifted.
In Latched mode, the Shift button toggles on and off in a manner similar to the Caps
Lock button on a standard keyboard. When on, it lights to indicate that the subsequent
selection(s) on the crosspoint selector row will be made from the shifted set of sources
(15 through 28). When off, the subsequent selection(s) come from the unshifted set
(1 through 14). If the user toggles the
Shift button to the state that is opposite from the
shift state for the currently selected input, then the crosspoint selector button blinks to
indicate this "out of sync" condition.
