Overview
ISO/IEC 23001-13:2019 - "Information technology - MPEG systems technologies - Part 13: Media orchestration" specifies an architecture and mechanisms for coordinating multimedia capture, processing and playback in heterogeneous device and network environments. The standard addresses temporal and spatial orchestration, messaging and control, timed metadata and its carriage, and orchestration data to enable synchronized, coordinated media experiences across sources and sinks.
Key topics
- Architecture: Defines overall architecture for temporal (time-based) and spatial orchestration, including source-side, sink-side and media-processor elements.
- Messaging & control: Specifies control channels and signaling concepts such as a wall clock reference, the MORE communication channel, and use of WebSocket for messaging.
- Timed metadata: Standardizes metadata types and timing for synchronization and spatial context:
- Position (global, relative, altitude)
- Orientation
- Regions of interest
- Quality metadata and stream-monitor information
- Capture-mask, camera and depth metadata
- Transport / carriage: Describes how timed metadata and orchestration information are carried in common container and streaming systems:
- ISO base media file format
- MPEG-2 systems
- MMT (MPEG Media Transport)
- DASH (for metadata in MPD)
- Orchestration data: Includes timeline synchronization, dvb-css correlation timestamps and other synchronization mechanisms to align media and metadata across devices.
- Normative and informative annexes: Provide source-side timeline synchronization, object models and control architecture guidance.
Applications
ISO/IEC 23001-13:2019 is intended for systems that require coordinated multi-device/media workflows, including:
- Live multi-camera production and remote production orchestration
- Multi-device synchronized playback (second-screen, collaborative viewing)
- Immersive media (VR/AR) where spatial positioning and orientation must be consistent
- Distributed capture and sensor fusion (e.g., multi-mic / multi-camera arrays)
- Broadcast and OTT services that need reliable metadata carriage and synchronization
Who uses this standard
- Device and camera manufacturers implementing coordinated capture features
- Broadcasters and studios designing multi-source live production systems
- Streaming platform and OTT engineers integrating synchronized metadata (DASH/MMT)
- Application developers for AR/VR, telepresence and multi-screen playback
- System integrators, CDN and middleware vendors implementing orchestration and timing services
Related standards
- ISO/IEC 23001 series (MPEG systems technologies)
- ISO base media file format (for metadata carriage)
- MPEG-2 systems, MMT and MPEG-DASH (referenced transport/profile mechanisms)
- DVB-CSS (correlation timestamp concepts referenced)
