Grass Valley iTX System v.2.6 - Manual (Page 155)

Configuring channels
By default, iTX displays black frames in a transition through black. From the Transition Matt
button, you can open PinPoint (the iTX search tool) and select a video clip for iTX to display,
instead of the black frames, in a transition of this type. Clicking C (to the right of the Transition
Matt entry) clears the selection; the entry returns to the default ("Black").
Output Server panel
Clicking Configure Output Server displays a dialog that enables you to set properties of the
output signal (e.g. the display resolution) and options that affect Output Server operations. See
later in this section, "Using the Configure Output Server dialog", page 159, for instructions on
using this dialog.
Alerts panel
Clicking Configure Alerts displays a dialog that enables you to set properties for alerts that
various services generate. See later in this section, "
Using the Configure Alerts dialog", page 165, for instructions on using this dialog.
Evergreen configuration panel
Evergreen content is standby content that iTX can play out when the media file required for a
schedule event is unavailable.
When Auto Replace is selected, iTX automatically replaces any video-clip event on the iTX
output server for which there is no media file at a specified time. By default, it does this when
the time to the start of the event equals the duration of the event. So, a video-clip event with a
duration of 30 minutes is replaced 30 minutes before its start time.
The minimum interval for the replacing of an event is 5 minutes; any schedule event with a
duration of less than 5 minutes is replaced 5 minutes before its start time.
iTX replaces the video-clip event with a sequence (which can itself be easily replaced if the
missing media file becomes available). In the sequence, iTX includes events based on evergreen
media items, which it selects from a PinPoint results list. PinPoint creates the list of evergreen
items by performing a search using search criteria that you specify. You can specify a different
set of search criteria for up to 5 different periods, or "windows", in a day; this way, you can
match the replacement items to the type of audience that the missing programme is intended
for.
For the first event in the sequence, iTX uses the longest available evergreen media item that
has a duration equal to, or shorter than, the media item in the original schedule event. iTX adds
other evergreen events as necessary; it tries to make the sequence fit as closely as possible, but
not exceed, the duration of the replaced schedule event.
Where the total duration of evergreen events falls short of the required duration, iTX displays
the off-air slide for gaps of longer than 1 second; otherwise, it holds the last frame of the last
event in the evergreen sequence on a freeze.
The time mode information of the clip being replaced is preserved and reassigned to the first
item of the evergreen sequence, e.g. if the first clip in a commercial break is a fixed event with
a manual hold, then the first clip of evergreen will have the same time mode settings.
Where multiple evergreen media items have the same duration, iTX selects the one least often
used.
