Overview
IEC 62379-2:2008 defines the audio-specific part of the Common Control Interface (CCI) for networked digital audio and video products. As Part 2 of IEC 62379, it specifies how audio formats, transport, metadata and device functions are represented for device management and control across digital networks. The standard provides machine-readable MIB definitions, status broadcast formats and examples that enable interoperable remote control and monitoring of audio equipment in distributed audio-over-IP and professional AV systems.
Key topics and technical requirements
- Audio format definitions: Identifies audio signal parameters and format identifiers (object identifiers) to represent the audio data state at any point in the signal chain.
- Transport and metadata: Defines audio transport format descriptors and metadata structures required for consistent handling of streams.
- MIB definitions for audio blocks: Provides managed object definitions for common audio functional blocks, including:
- Audio ports and AES3 ancillary data
- Mixers and crosspoint matrices
- Clip players and limiters
- Converters and level alarm blocks
- Status broadcasts and page formats: Standardizes how devices publish status pages and grouped status information for monitoring tools.
- Machine-readable annexes: Includes annexes with machine-readable audio formats, block definitions, status page groups and worked examples for integration and implementation.
Practical applications
IEC 62379-2 is designed to enable consistent remote management for systems that convey audio across digital networks. Typical applications include:
- Networked pro-audio systems and broadcast studios where centralized control of mixers, crosspoints and processors is required
- AV-over-IP installations in venues, campuses and enterprise environments needing standardized device discovery and status reporting
- Equipment firmware and control software that must interoperate with other vendors by using common audio MIBs and status pages
- Monitoring systems that aggregate device states, alarms and audio format mappings from distributed endpoints
Who uses this standard
- Audio equipment manufacturers implementing networked device management and interoperability
- System integrators and AV designers deploying networked audio infrastructures
- Broadcast engineers and operations teams managing distributed audio resources
- Firmware and control-software developers building SNMP/MIB-based or similar management interfaces
