# The scheduling window defines when the entries of each schedule are queued for play-out. The actual window (scheduling_window_start - scheduling_window_end)
# should be higher then the `fetching_frequency` to allow proper queuing. Otherwise the fetch might never hit the scheduling window, because the scheduling
# logic is attached to the fetching logic. 
# 
# Following operations are related to the scheduling window:
# 
#   - Deletion of schedules/timeslots: Those are only accepted until the **start** of the scheduling window
#   - Update/Delete/Assignment of playlists and entries: Those are accepted until the **end** of the the scheduling window; existing queued entries are updated
#   - Pro-active fallback handling: Within the window it is continousely evaluated if some fallback playlist should be applied. The queued items are updated accordingly
#
# After the end of the scheduling window the pre-rolling phase starts. It's recommended that the end of the windows is approximately 4x times
# higher than the preroll_offset, to leave enough space for all 4 fallback scenarios to pre-roll (normal, show, timeslot and station).
# Note, the values for windows is defined as a offset minus the actual start of the schedule in seconds.

# Sometimes it might take longer to get a stream connected. Here you can define a viable length.
