Description
With the development of standards such as SMPTE ST 2110 suite for transmitting signals and AMWA NMOS for controlling systems, there is a move toward replacing broadcasters' infrastructure with IP-based production systems.
This movement starts with smaller parts such as OB vans and a few studios. Since the advantage of IP network is connectivity, it is desirable that each of these independently introduced systems can be connected and operated as one large program production system that can be shared among many program productions.
An NMOS-compliant program production system has an RDS with information on all equipment in the production system. The challenge is how to configure and operate RDSs when connecting multiple NMOS-compliant systems.
In addition, to share resources in the system among multiple program production, it is imperative that the equipment in operation is protected from accidental operations.
To achieve this, a function to manage the operational schedule of each equipment and a mechanism to issue authorizations based on the schedules are needed.
The NMOS IS-10 specification defines an authorization method but authorizations are issued by the decision the operator requesting authorization makes, and there is no study to issue authorization based on a schedule managed by resource administrator.
In this presentation, we propose a method for managing multiple RDSs and issuing authorizations based on operational schedules in order to form a large program production system consist of multiple NMOS-compliant systems. The equipment already in place can be used with the proposed method because the APIs for registration and authorization are the same as a standard NMOS-compliant system.

- A method of connecting multiple NMOS-compliant systems to form a large program production system is proposed. - The proposed method is based on AMWA NMOS so that NMOS-compliant equipment already in place can be used. - The proposed method utilizes an equipment usage schedule management service to protect equipment from accidental operation and allow resource sharing.
