There are three parameters that can be modified when configuring your schedule information:
Playout Rate
The amount of bandwidth you want to allocate for schedule and present/following
information (the higher the playout rate, the shorter the rotation time).
Playout Limit
The amount of schedule information being sent out.
Priority
The number of times schedule information for the next 12 hours is repeated in your
carousel.
Actual Schedule
Only
When enabled, the EIT-Schedule Actual table will only be sent on this output. The
EIT Schedule Other will be disabled.
Assuming 1 rotation =
r
, the figures below illustrate these three parameters and how they can influence
the output of schedule information.
