Full title and description

Information technology — MPEG systems technologies — Part 13: Media orchestration. This international standard specifies an architecture for media orchestration and defines associated messaging and control mechanisms, timed metadata types, carriage methods for timed metadata, and the structure of orchestration data used to coordinate media capture, processing and presentation across devices and streams.

Abstract

ISO/IEC 23001-13:2019 defines a media orchestration framework that enables temporal and spatial coordination of primary media and ancillary timed content. It details control and messaging constructs (including a wall clock reference and a MORE communication channel), timed metadata models (position, orientation, regions of interest, quality and capture metadata), and recommended carriage/transport mechanisms for embedding and delivering that metadata alongside media in common container and streaming systems.

Scope

The standard specifies an architecture and normative concepts for orchestrating media and associated timed metadata across heterogeneous capture, transport and playback environments. It covers temporal orchestration (synchronizing timelines across sources and sinks), spatial orchestration (position/orientation and spatial relationships), messaging and control channels, the definition and timing of metadata elements that describe ancillary content, and the carriage options for that metadata within common file and streaming formats. The scope includes normative models and examples for aligning ancillary timed content with primary media to enhance multi-device, multi-stream and immersive media experiences.

Key topics and requirements

• Architecture for media orchestration: definitions for source-side, sink-side and media-processor components supporting temporal and spatial orchestration.
• Temporal orchestration: timeline synchronization, wall clock reference, timeline mapping and alignment mechanisms for multi-stream coordination.
• Spatial orchestration: metadata for global/relative position, altitude and orientation to support spatially consistent rendering (e.g., multi-camera or immersive setups).
• Messaging and control: definition of the MORE communication channel, signaling for control channels, and use of protocols such as WebSocket for low-latency messaging and control.
• Timed metadata types: standardized metadata elements including position, orientation, regions of interest, quality metrics/stream-monitor data, capture-mask, camera metadata and depth information.
• Carriage and transport: recommendations for embedding and transporting timed metadata using common formats and systems (ISO Base Media File Format, DASH-related metadata, MPEG-2/MMT carriage mechanisms, and other container/streaming options).
• Orchestration data models: object models, timeline structures and message formats for conveying orchestration instructions and annotations.
• Normative and informative annexes: examples, implementation guidance and mapping to existing carriage mechanisms and reference technologies.

Typical use and users

ISO/IEC 23001-13 is intended for implementers and architects of multimedia systems who need coordinated media capture, delivery and presentation. Typical users include broadcast and OTT service providers, live and remote production integrators, device and camera manufacturers, developers of second-screen and synchronized multi-device applications, immersive/VR/AR system designers, and researchers working on multi-sensor and multi-stream synchronization.

Related standards

Related parts of the MPEG-B (ISO/IEC 23001) family and other MPEG/streaming standards are often used alongside Part 13, for example: ISO/IEC 23001-10 (carriage of timed metadata metrics in ISOBMFF), ISO/IEC 23001-11 (energy-efficient media metadata), ISO/IEC 23001-12 (sample variants), ISO/IEC 23001-14 (partial file format), ISO/IEC 23001-15 (carriage of web resources in ISOBMFF), and relevant streaming and transport standards such as DASH and MPEG Media Transport (MMT). Implementations typically map Part 13 metadata and signaling into the container and transport formats specified by those related standards.
