About Output Server 2
iTX Output Server 2 is Grass Valley’s next generation iTX video engine. It integrates with the
current iTX framework, allowing customers to easily upgrade their existing channels.
Working alongside our next generation video engine is our new automation controller,
TXPlay 2, which supports the new features and functionality that Output Server 2 provides,
and our new caching mechanism, Media Cache 2.
Output Server 2 has improved standards compliance, more flexibility and greater stability,
and forms the basis for future iTX development. Among the new features and functionality
offered by Output Server 2 are improved image quality, the ability to perform on-air
updates for AFD and duration changes, per stream configuration for Dolby D and E and full
audio processing for XG inside.
Whilst Output Server 2 supersedes the previous video engine, Output Server 1 is still
supported and it is even possible to run both video engines in the same iTX system. See
Transitioning to Output Server 2 on page 15.
