iTX Output Server 2
Channel Configuration Guide
When disabled, the Start Window and End Window times for sequences are
applied relative to the start time of the item.
Note: Once an availability window has been set and applied it cannot be
removed. If the availability window is changed, the new window will take
effect, but the previous window will not be removed until the Output Server
2 service is restarted.
• In Event Editor for the sequence item:
• Specify the sequence’s availability window by entering timecodes in the Start
Window and End Window fields.
How these times are interpreted is dependent on the Fixed Availability
Windows option in Channel Config 2.
• If required, enable SCTE104 LocalAd.
iTX inserts an SCTE 104 message to trigger the insertion of local advertisement.
It does this when it plays out a sequence as a result of receiving an SCTE
message containing a delay.
Unless you require this specific functionality, you should ensure the option is
not selected.
For more information on configuring availability windows see the iTX System Administration
Guide.
For more information on working with sequences see the iTX Desktop Operator Guide.
Configuring Subtitles
IMPORTANT
• For basic closed captions or subtitles to function you must configure a
minimum of one stream and one service (e.g. page 888).
• The Subtitles tab is a placeholder for future development. The following
functionality is not currently supported:
• The
Channel section
• Multiple language closed captions.
• Open captions.
Accessing the Subtitles Tab
To access the Subtitles tab:
1 Open the Output Server 2 user interface for the channel you want to configure, as
described in Accessing the Output Server 2 User Interface , on page 31.
2 Go to Configuration > Subtitles tab.
The Subtitles configuration options appear. By default all of the subsections are
collapsed.
