Display settings
Although the Display setting page has various settings, the bulk of the settings deal with the
OVERFLOW and UNDERFLOW properties, which are set on this page and reported in the
Overflow column in the Playlist Editor.
At the center of the overflow/underflow discussion are TIMESLOTS . A timeslot is a set of
playlist elements between two hard-starts (a hard-start is a playout type for bringing playlist
elements to air). The total time available in the timeslot is determined by the difference of
the two hard-start times. Ideally, the timeslot should be filled with enough content to exactly
fill this time.
Overflow (or underflow) refers to the difference between the total time of the content in a
timeslot and the time available in the timeslot. When the total time of the content in a
timeslot exceeds the time available, there is an overflow. Similarly, when the total time of
the content in a timeslot is less than the time available, there is an underflow.
The overflow column in the playlist indicates if a timeslot has an overflow or an underflow.
The time difference is displayed as a positive value for overflows and a negative value for
underflows. Furthermore, it is possible to specify thresholds for overflow and underflow.
When the overflow or underflow in a timeslot exceeds the threshold, the overflow column is
colored to draw attention to the problem.
Figure 6-5. Xplay’s Display settings
• Overflow/underflow error color 1 - Specifies the color used to in the playlist’s
Overflow column to indicate that a timeslot contains an overflow or underflow that
exceeds acceptable thresholds.
• Overflow/underflow error color 2 - Specifies a second color used to indicate that a
timeslot contains an overflow or underflow that exceeds acceptable thresholds. The
need for a second/alternating color is to distinguish between successive timeslots that
contain an error.
• Normal status color 1 - Specifies a color used to in the playlist’s Overflow column to
indicate that a timeslot does not contain an overflow or underflow that exceeds
acceptable thresholds.
