Grass Valley iTX System v.2.6 - Manual (Page 185)

Configuring channel plug-ins
When iTX generates timecode, it uses the timecode of the in-point of the video-clip it is playing
out as a reference for all other frames in the clip; it adds the timecode on the line you specify in
the Timecode Insertion Line box.
• The required line number for a HD channel is 10.
• If you do not want iTX to generate timecode, enter a value of 0.
In general, the setting is for video clips (such as those from an Omneon Spectrum video server)
that do not contain a timecode track.
If a video clip already contains timecode on the specified line, iTX overwrites this. If it contains
timecode on a different line, iTX simply adds a second timecode track on the specified line. You
should ensure the number in the Timecode Insertion Line box matches the number of the line
that the downstream device reads timecode from.
Through other features on the panel, you can set up iTX to play out VTR events; i.e. events
featuring video clips that are on videotape.
• Using the VTRs button, you can specify which VTRs are to be available to the channel
for playout.
• By entering a number in the VTR Live Delay box, you can cause iTX to delay playout of
a video clip by that number of frames. Although the setting is normally zero, a small
delay may be necessary for operational reasons.
Clicking VTRs displays a dialog with two panes: the Available pane has a list of all VTRs
registered in the iTX system; the Selected pane shows which of these VTRs are available for
playout. You may move VTRs to or from the Selected pane.
Note: VTRs are registered and controlled through the Device Manager service.
The Schedule Import Configuration panel
iTX uses the Schedule Import plug-in to import schedules in files from third-party traffic
systems. The schedules must be in the format defined by the iTX Import Protocol; schedule files
in this format have the filename extension ".osc".
For more information about the iTX Import Protocol, contact iTX Support.
An imported schedule may contain events that refer to generic logos (logo_0 to logo_7), CG
templates or graphics-script templates. You need to map the logos and templates to media files
on the Media Store so that iTX can play them out.
Similarly, an imported schedule may contain events that refer to generic GPI outputs (gpi_0 to
gpi_7), which you need to map to the outputs of a GPI matrix in your iTX system.
