System Architecture
The basic iNEWS Command system is comprised of servers that run a variety of Command
services, workstations that run the client software, and devices, such as Avid AirSpeed video
servers, Thunder production servers, and Deko graphics systems.
Avid iNEWS Command is scalable and can adapt to work in traditional newsroom-based
playlist creation to production-centric workflows where running orders are created inside the
iNEWS Command playback application. All of the services can run on a single computer, or
they can be spread out across multiple computers with redundant services configured as
backups to take control if any or all of the primary services should become unavailable.
An example of a basic Command system architecture is shown in the following illustration:
Avid recommends having all primary Command services on one designated primary server
with the backup services running on other backup servers. Command determines primary
and backup roles based on the length of time the service has been running. The server that
has been running longer is the primary. Therefore, to get all primary services on one server,
it is necessary to start the primary server first; when all services have started, start the
backup servers. This is the only way to ensure all services on the primary server take on the
primary role, which allows for more consistent behavior during times when redundancy is
needed, and it helps simplify any necessary troubleshooting efforts.
