About Output Server 2
Output Server 2 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, full
audio processing for XG inside and the ability to perform dual channel or simulcast
broadcast from a single playout server.
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.
