Adding Channels to an ITX Playout Server
This chapter explains how to add each type of channel to an iTX system, via the iTX Channel
Config dialog for TXPlay 2, and the basic rules for ensuring your combination of channels
and playout servers provide a solid resilience model.
For detailed information on setting up an iTX system, refer to the iTX System Administration
Guide.

Channel Resiliency Guidelines
When adding channels to an iTX system consider the following guidelines:
• Backup channels should be kept on separate playout servers from their main channels.
• If your playout servers have Corvid 44 or 88 SDI I/O cards, a dual channel playout type
can be used transmit the main for one channel and backup for a different channel. For
example:
• Playout Server 1 runs channel A main and channel B backup.
• Playout Server 2 runs channel B main and channel A backup.
• A simulcast channel does not provide redundancy for a main channel. If a main channel
fails its simulcast follower will also fail. Therefore, it is acceptable to run a main channel
and its simulcast channel on the same playout server.
• If your playout servers have Corvid 44 or 88 SDI I/O cards, it is acceptable to run the
main channel, its backup, the simulcast and the simulcast backup in the following
ways:
• Playout Server 1 runs the main channel and the simulcast backup.
• Playout Server 2 runs the simulcast channel and the main backup.
