About Playout Types for Output Server 2
iTX Output Server 2 supports three different types of playout.
Single Channel Playout
Single channel playout means the channel has a single input and a single output. This
playout type can be used for main channels in any iTX system, including backup channels
running on their own playout servers.
Dual Channel Playout
Dual channel playout means there are two independent channels running on a single
playout server, each with a single input and output. This can be used to run a main channel
and the backup of another channel on a single playout server (providing it is equipped with
a Corvid 44 or Corvid 88 SDI I/O card, such as the Grass Valley Playout Appliance 2 server).
Simulcast Playout
In a simulcast system, two channels share two inputs, but have independent outputs. A
typical use case for a simulcast system is to generate HD and SD transmissions from a single
schedule that is loaded on to the main channel. Because the main and simulcast channels
have different requirements for the resolution, aspect ratio control (ARC) and audio output,
the two channels are configured independently.

Note:
• * Output Server 2 does not support playout servers with dual SDI I/O cards (i.e. two
Corvid L/P cards). If your playout server is equipped with dual SDI I/O cards, only
the card that Windows identifies as device 0 will be used and only in single channel
mode.
• Although iTX 2.x supports the Kona 3G SDI I/O cards, it does not support Kona 3
card.
