Overview
IEC 62379-7:2015 is Part 7 of the IEC 62379 series, defining the measurement aspects of the common control interface for networked digital audio and video products. It specifies information models and managed objects that are specific to measuring the service experienced by audio and video streams, aligned with the requirements of the EBU ECN‑IPM Measurements Group. The standard complements IEC 62379‑1 by detailing measurement blocks, textual conventions and machine‑readable MIB definitions for monitoring media quality and device conditions.
Key topics and requirements
- Measurement information blocks (MIBs): Defines structured measurement blocks for network, audio, video, receiver point and temperature information.
- MIB tables and entries: Standardized tables such as nMtBlockTable, aMtBlockTable, vMtBlockTable and rxPointTable with blockId and related fields to report measurements.
- Audio and video format definitions: Specifies format descriptors used in measurement reporting (audio component numbers, video source formats, coding and bit‑rate types).
- Network measurement fields: Network transport type, multicast/IGMP details, IP addresses and port identifiers needed for stream measurements.
- Receiver point measurements: Buffer sizes, occupancy, media delivery index (MDI) and timestamping fields for receiver‑side quality assessment.
- Temperature and device health: Managed objects to report temperature location, status, warnings and trends for environmental monitoring.
- Machine‑readable conventions & examples: Includes machine‑readable block definitions and informative worked examples (annexes) to aid implementation.
Practical applications
- Broadcast and IP‑media monitoring: Use to monitor Quality of Experience (QoE) for live streams and multicast distribution in radio and television facilities.
- Networked AV equipment manufacturers: Implementers use the MIB definitions to expose standardized measurement data for interoperability.
- System integrators and operators: Enables centralized monitoring, troubleshooting and SLA verification across IP audio/video installations.
- Network management / NMS integration: The defined MIBs can be integrated into SNMP‑based network management systems for automated alarms and reporting.
- QA and lab testing: Provides a consistent framework for measuring stream performance and device health during testing.
Who should use this standard
- AV equipment vendors and firmware developers
- Broadcast engineers and media network operators
- System integrators deploying IP audio/video infrastructures
- Network management and monitoring tool vendors
- Standards and QA teams working with EBU ECN‑IPM measurement practices
