walls also include a secondary tally indicator for Look Ahead. Look Ahead
tributaries do not necessarily leave the switcher as video signals. For
example, an ME has four program outputs but only two physical preview
outputs. The LAP information for all four program outputs may be
included in a tally calculation.
However, if an ME is placed down stream of Pgm-Pst the On Air tally cal-
culation can be configured to start at that ME's program outputs. If this sit-
uation is planned, it is recommended that aux buses be set up to provide
the real program outputs for the switcher and the On Air calculation con-
figured using those aux buses as the tributaries.
You can use more than one starting point for tally calculations. Program-
mable clean feed (FlexiKey) and DoubleTake allow the exclusion of video
signals from the ME main output (PGM A) that appear on one of the other
program outputs. Include the other program outputs with the ME main
output (PGM A) as calculation starting points to tally all the On Air
sources.
The Bus Selection tally calculator indicates which sources are selected on a
specified set of switcher buses. The tally calculator using this method does
not trace tributaries upstream; it only tells what sources contribute to the
specified bus(es), even if the source is an ME. For example, a Bus Selection
tally calculation could be set up to indicate which source is selected on the
Pgm-Pst A bus, permitting audio-follow-video selections to be run by the
tally system.
Switcher Relay Tally Calculator Menus
The Switcher Tally menus are used to select calculators, methods, and
levels, name calculators, and assign items to Tributaries.
Kayenne K-Frame has six independently running tally calculators. For
example, the system can calculate On Air tally independently for suite 1
and suite 2, and at the same time can calculate Look Ahead tally, and ME
output tallies for three MEs. The first of the tally calculators is reserved for
On Air tally calculations for the currently logged in suite (1 or 2). The other
four tally calculators can be assigned to either suite 1 or suite 2.
Up to four tributaries can be included as the basis for each tally calculation.
For example, multiple program outputs of the PGM/PST bank are typically
included in the On Air tally calculation. The final tally source list is a union
of the sources found on each of the four tributaries. If aux buses are used as
the program outputs of the switcher, up to four aux buses can be the basis
of On Air tally calculations. Tally calculations do not require actual outputs,
for example, LAP tributaries are virtual and may never leave the ME.
Selecting an

Tally Calc 1-4
tab delegates the menu controls to the
selected calculator. The On Air Tally menu is shown in Figure 94 .
