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.
