NMOS API Mirroring for IP Receiver Flow State Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In media production environments, there is a need for standardized communication protocols to enable efficient interaction and mirroring of receiver nodes, particularly for testing and maintenance purposes, as existing systems lack seamless integration and automation capabilities.
Innovation Solution
The implementation of Networked Media Open Specifications (NMOS) APIs allows for IP-based communication between nodes, enabling a mirror node to replicate the flow state of a receiver node through polling mechanisms or connection manager control, ensuring synchronized data transmission and reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If standardized communication protocols are implemented, then interoperability and ease of operation are improved, but device complexity increases due to integration of multiple protocols and interfaces
Solution Approach 1:
The patent introduces a standardized API layer as an intermediary between diverse media production equipment and control systems. This API acts as a mediator that translates various equipment-specific protocols into a common interface, enabling seamless interoperability without requiring complex point-to-point integrations between each device pair.
2Measurement precision
If receiver node mirroring is implemented for testing purposes, then measurement precision and reliability are improved, but loss of time occurs due to configuration setup and synchronization overhead
Solution Approach 1:
The patent implements a receiver node mirroring capability that creates a virtual copy of the target receiver's flow configuration and state. This copy can be used for testing and verification purposes without affecting the original receiver, allowing precise measurement of flow states and configuration validation while reducing setup time through template-based replication.
Solution Approach 2:
The system performs preliminary configuration actions by pre-setting up mirror receiver nodes with identical flow states and configurations before actual testing begins. This advance preparation allows testing to start immediately with accurate baseline data, eliminating the need for time-consuming configuration during test execution.
3Productivity
If automated interactivity is implemented through standardized protocols, then productivity is improved, but device complexity increases due to automation infrastructure requirements
Solution Approach 1:
The patent implements self-service automation where the standardized API enables equipment to automatically discover, register, and configure themselves within the media production network. Devices can autonomously manage their own connections, flow states, and mirror relationships without requiring manual configuration or complex centralized control infrastructure, thereby improving productivity while keeping the automation infrastructure simple.
Data Source
AI summary
Disclosed is a mechanism of operating a Networked Media Open Specifications (NMOS) Application Programming Interface (API) at a node controlling a local device including a local receiver. A flow message is received via the NMOS API. The flow message contains a flow state of a target receiver at a remote node. A local receiver at the local device is configured to mirror the flow state of the target receiver at the remote node. The NMOS API then notifies a registry with an updated flow state of the local receiver at the local device.
