Overview
IEC 62379-1:2007 defines the common control interface and general framework for products that convey audio and/or video across digital networks. Part 1 establishes the core model and services used across the IEC 62379 family, enabling consistent control, discovery and management of networked digital audio and video devices. This edition covers unit modelling in terms of blocks, management via a Management Information Base (MIB), status broadcasts, calls, privilege levels, automation and procedures such as software uploads and scheduled operations.
Key Topics
- Control framework and block model: Devices are represented as “units” composed of functional blocks (inputs, outputs, processing). The framework defines how blocks are described, linked and discovered to enable modular, scalable designs.
- Management Information Base (MIB): Standardized MIB objects convey unit identity, block configuration, real-time clock and reference clock information, software upload status and scheduled operations.
- Status broadcasts and page groups: Mechanisms and formats for broadcasting unit status (basic identity, time-of-day, scheduled operations) to facilitate monitoring and “plug-and-play” behaviour.
- Procedures and operations: Defined procedures for uploading software components, defining file formats and areas, requesting/executing/delaying/aborting scheduled operations.
- Control transport and encapsulation: Guidelines for how control and status messages are carried and encapsulated over networks (see Parts 5 and 6 for network-specific transports).
- Security and management: Support for privilege levels, calls, automation and migration pathways (e.g., OIDs and XML) to integrate with enterprise management systems.
Applications and Who Uses It
IEC 62379-1 is intended for professionals and organizations designing, deploying or managing networked AV systems, including:
- Manufacturers of networked audio, video and multimedia equipment (encoders, decoders, mixers, routers)
- Broadcast system integrators and facility engineers seeking interoperable control interfaces
- Network architects implementing AV over IP, broadcast distribution or studio automation
- Software developers building device management and monitoring tools that use MIBs or status broadcasts
Practical benefits include plug-and-play discovery, consistent device control, easier integration of new functionality, and standardized mechanisms for software updates and scheduled tasks.
