iTX Output Server 2
Channel Configuration Guide
There are two sides to configuring SCTE104: the features you want to use need to be
configured in the SCTE104 tab on the Output Server 2 Configuration panel, while the
message types need to be configured via one of two different plugins in the iTX Desktop:
• The legacy VANC plugin
• The enhanced SCTE104 plugin
The differences between these plugins are explained below.
About the VANC plugin
The VANC plugin is the legacy SCTE104 solution, which supports the following features:
• The ability to react to inbound splice request commands sent in a Multiple Operation
Message, providing they are the only command in the Multiple Operation Message.
• Pass-through of splice request commands to downstream services. Any unsupported
commands are stripped from the message.
• Insertion of outbound splice commands.
About the SCTE104 plugin
The SCTE104 plugin supports the following enhanced features:
• The ability to react to inbound Multiple Operation Messages containing more than one
command, including:
• Splice request commands.
• Local and National Avail Insert Commands, either individually or both in the same
Multiple Operation Message.
• Legacy DTMF triggers.
• Enhanced message pass-through, which provides the following additional
functionality:
• All inbound SCTE104 messages can be either passed through or blocked.
• When pass-through is enabled, iTX allows for the passing of “NULL” SCTE messages
for heartbeating to downstream services.
• The ability to enable or disable pass-through for all commands within a Multiple
Operation Message.
Splice commands received outside of a configured available window are unchanged.
• Insertion of outbound Multiple Operation Messages containing the following
additional commands:
• Local and National Avail Insert Commands, either individually or both in the same
Multiple Operation Message.
• Legacy DTMF triggers.
