ISO/IEC 23005-6:2019

Overview

ISO/IEC 23005-6:2019 - part of the ISO/IEC 23005 series (MPEG‑V) - defines the common data types and supporting tools used across the media context and control framework. Rather than standalone interfaces, this part supplies the syntax and semantics for reusable building blocks (basic datatypes, colour types, timestamps, classification schemes) and standardized profiles and levels intended to be referenced by other parts of ISO/IEC 23005 (e.g., device, sensor and actuator descriptions, media orchestration).

Keywords: ISO/IEC 23005-6, MPEG-V, media context and control, common types and tools, colour datatypes, timestamp.

Key topics and technical requirements

• Basic datatypes: canonical definitions used as building blocks across the series (XML and binary syntaxes and semantics).
• Colour-related datatypes: colour primitives and validation rules to describe device colour characteristics and commands for lighting/visual actuators.
• Time stamp type: standardized timestamp syntax/semantics for commands, sensed data and timing-sensitive interactions.
• Binary and XML representations: schema wrapper conventions, mnemonics and a common header for interoperability between textual and binary encodings.
• Descriptor semantics: rules governing descriptor components shared across tools.
• Classification schemes (Annex A): normative vocabularies and referencing mechanisms for terms used by multiple parts (e.g., device types, 3D printing descriptors, sensor technologies).
• Profiles and levels: predefined collections and constraints (including a Media Orchestration profile) that combine tools from ISO/IEC 23005-2 and ISO/IEC 23005-5 to address specific application domains.
• Schema and examples: schema documents and full media orchestration information provided in informative annexes (Annex B, C).

Applications and who uses it

ISO/IEC 23005-6 is targeted at implementers and integrators who need consistent, interoperable data models between the real and virtual worlds:

• Device and actuator manufacturers (lighting, haptics, printers)
• Sensor and IoT solution developers
• Media orchestration platform vendors and system integrators
• Software engineers building adaptation engines between sensors/actuators and virtual content
• Broadcasters, content providers and researchers implementing multi-sensorial experiences Using these common types ensures consistent command, capability and sensed-data representations across heterogeneous systems.

Related standards

• ISO/IEC 23005 series (MPEG‑V) - other parts define sensors, actuators, scene representation
• Normative references included: ISO/IEC 15938-3 and ISO/IEC 15938-5 (multimedia description interfaces)
• Annexes in ISO/IEC 23005-6 provide classification schemes and schema documents for implementation guidance

This part is essential for building interoperable media-context ecosystems where precise colour, timing and datatype semantics are required.
