ISO IEC 23005-3-2019 PDF

Full title and description

Information technology — Media context and control — Part 3: Sensory information. This part of ISO/IEC 23005 specifies description languages and vocabularies for representing sensory effects (e.g., light, wind, fog, vibration, scent, temperature) to enrich audio‑visual content and enable interoperability between media and multisensory devices.

Abstract

ISO/IEC 23005-3:2019 defines the Sensory Effect Description Language (SEDL) — an XML Schema–based language — and the Sensory Effect Vocabulary (SEV), an XML representation of concrete sensorial effects. The document specifies syntax and semantics for describing sensory effect metadata that can be associated with media and mapped to device commands by an adaptation/mediation engine; the adaptation engine itself is outside the scope of this part.

Scope

This part specifies the description languages and vocabularies used to express sensory effects that complement traditional audio‑visual streams. It defines SEDL (Sensory Effect Description Language) and SEV (Sensory Effect Vocabulary) as XML‑based representations for authoring sensory effect metadata; it does not define the adaptation engine that maps sensory metadata to concrete device commands. The scope is limited to information representation (metadata) for multisensory media, not device control implementations.

Key topics and requirements

• Definition of Sensory Effect Description Language (SEDL): XML Schema–based model for sensory effect metadata.
• Specification of Sensory Effect Vocabulary (SEV): XML representations of concrete effects (light, colored light, flash, temperature, wind, vibration, sprayer, scent, fog, color correction, motion/kinesthetic, tactile, etc.).
• Syntax and semantics for sensory metadata elements and groups, including declarations, references and effect composition.
• Extensibility model allowing application domains to extend or derive new effects via XML Schema mechanisms.
• Separation of concerns: metadata representation is standardized while mapping/adaptation to device commands (rendering) is intentionally left outside this part.

Typical use and users

Authors of multisensory media content, system integrators, platform and device vendors, multimedia application developers, and research groups working on immersive media or quality‑of‑experience (QoE) extensions will use this standard. Typical uses include annotating video/games/VR with sensory effect metadata for synchronized rendering on fans, lights, scent dispensers, haptic actuators, temperature devices and other interaction hardware via a mediation/adaptation engine.

Related standards

ISO/IEC 23005-3:2019 is part of the ISO/IEC 23005 (MPEG‑V) series. Closely related parts include: Part 1 (Architecture), Part 2 (Control information — device capabilities and user preferences), Part 4 (Virtual world object characteristics), Part 5 (Data formats for interaction devices / Device Commands and Sensed Information) and Part 6 (Common types and tools). Normative and referenced links also include related MPEG and MPEG‑21 items used for multimedia adaptation and delivery.

FAQ

Q: What is this standard?

A: ISO/IEC 23005-3:2019 is the part of the ISO/IEC 23005 (MPEG‑V) family that standardizes representation formats for sensory effects (sensory information) so media can be enriched with metadata describing non‑auditory/non‑visual effects.

Q: What does it cover?

A: It covers the Sensory Effect Description Language (SEDL) and the Sensory Effect Vocabulary (SEV), defining syntax and semantics (XML‑based) for expressing sensory effect metadata such as light, wind, fog, vibration, scent and temperature. It does not define the adaptation engine that converts metadata into device‑specific commands.

Q: Who typically uses it?

A: Content creators, multimedia system developers, device manufacturers, integrators of immersive systems (theme parks, cinema/haptics setups, VR/AR platforms), and researchers working on multisensory experiences and QoE evaluations.

Q: Is it current or superseded?

A: ISO/IEC 23005-3:2019 is the published edition that superseded earlier 2011/2013/2016 editions; the 2019 edition is the current published version of Part 3 (replacing the 2016 edition).

Q: Is it part of a series?

A: Yes — it is Part 3 of the ISO/IEC 23005 series (commonly referred to as MPEG‑V), which includes parts for architecture, control information, virtual world object characteristics, data formats for interaction, common types/tools and conformance/reference software.

Q: What are the key keywords?

A: SEDL, SEV, sensory effect, multisensory metadata, MPEG‑V, XML Schema, haptics, scent, ambient effects, device capabilities.
