Signal Routing
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 Kayak system provides shifted
buttons to allow access to more input sources from the control panel.
For example, on the Kayak HD-100 system, up to 28 sources can be mapped
at one time, 14 to the unshifted source selection, and 14 to the shifted but-
tons. 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 cur-
rently selected input, then the crosspoint selector button blinks to indicate
this “out of sync” condition.
A useful configuration is to have sources normally used for backgrounds
(e.g. VTRs) mapped to unshifted buttons, and sources normally used as
keys (e.g. character generators) mapped to shifted buttons. Then you can
then set all the background buses to an unshifted preference, and all the key
buses to a shifted preference. All normal source selections can then be made
without having to use the shift modifier buttons.
It is also possible to have a different assignment for background and key
buses.
Source Scalars (HD Only)
Each Mix Effects (M/E) has 4 scalars that can be used for scaling video
sources of the same frame rate but different resolutions than the video
being processed.
The scalars are software enabled options. Two scalars are enabled on one
option, up to 2 options per M/E maximum. The scalars are fixed to a spe-
cific M/E.
