panel. This required the operator to account for the state of the Shift button
before selecting any source.
The Kalypso system provides an improved mechanism for shifted and
unshifted source selection, and allows setting individual shift preferences
for each bus. The result is improved source selection flexibility, speed, and
reliability.
On a 4-M/E Kalypso system, up to 72 sources can be mapped at one time,
36 to the unshifted source selection and reentry buttons, and 36 to those
shifted buttons. Instead of a single modal Shift button, an additional
Unshift button is available. Buses with a Shifted shift preference will select
the shifted source when no modifier button is held down. Unshifted shift
preference busses select the unshifted source when no button is held down.
Holding down the Shift button while pressing a source button always
selects the Shifted source for that bus, while holding down the Unshift
button always selects the unshifted source. This selection is consistent
regardless of the shift preference set for that bus. For example, holding
down the Shift button for a bus with a Shifted shift preference still causes
selection of shifted sources (same as no modifier button held down).
Each source selection bus on a Kalypso system can be individually config-
ured with a shift preference that determines which set of sources are
selected on that bus when a modifier button (
Unshift or Shift ) is not held
down. This allows different sets of sources to be made available for imme-
diate selection on different buses. Note that if only one source is mapped to
a button, that source is selected regardless of the shift preference or Unshift
or Shift hold downs.
It is recommended that shift preferences be set so they are easy to
remember. For example, you can set all the buses to have an unshifted pref-
erence. Or you can set only M/E 1 to a shifted preference, so you can
quickly access these sources on that M/E. Another 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 gener-
ators) 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 prefer-
ence.All normal source selections can then be made without having to use
the shift modifier buttons.
Mix/Effects (M/E)
An M/E is a subsystem of a video production switcher that can create a
composite of two or more pictures. An M/E includes multiple source selec-
tion buses and provides transition (mix and wipe) and keying capabilities
on the selected signals. An M/E can be organized with the keying circuitry
separate from the mixing circuitry, which permits Effect Send capabilities
(see Effects Send
on page 72 for more information).
