Grass Valley iTX System v.2.6 - Manual (Page 179)

Configuring channel plug-ins
The GPI Configuration panel
In the GPI Configuration panel, you set the actions that iTX performs when it receives GPI
inputs.
In the Matrix box, you choose the matrix name of the GPI device that is to provide the GPI
inputs; the box displays the name of the service controlling the device.
To set a GPI input for an action, you click the action button (e.g. Take Next) to display the
Select Input dialog; through this dialog, you select the GPI input. When you close the dialog, the
box displays the name of the selected GPI input.
Note:
• A GPI input for Take Next takes the next schedule event (the one following the current
on-air event).
• A GPI input for Take Next Sequence takes the next sequence to air, but only if iTX
receives the trigger within the sequence availability time.
The VANC Configuration panel
Through this panel, you set the properties for VANC (Vertical Ancillary) data in a live video
signal. The available VANC message types depend on XML configuration files located in a folder
on the Output Server machine. The default path to the folder is:
C:\Program Files (x86)\iTX2.0\Services\TXPlay
After you select a message type in the Type box, the panel displays settings for properties
associated with that type. The properties are defined in the configuration file for the message
type.
For example, you set the following properties for a splicer message (used to trigger the
insertion of media content, usually advertisements, into the channel output):
• In the Insert Type box, you select a splicer message type.
• In the Line Number box, you enter the number of the VANC line that carries the
message.
