Overview
ISO/IEC 14543-5-11:2018 specifies a Remote User Interface (RUI) for the ISO/IEC 14543-5 series on Intelligent Grouping and Resource Sharing (IGRS) for Home Electronic Systems (HES) Class 2 and Class 3. The standard defines the architecture, configuration models and mechanisms that allow an adaptive user interface to be displayed on - and controlled from - remote devices or control points. It is a normative part of the HES architecture family and includes a formal RUI Description Language (RDL) with a schema.
Key topics and technical requirements
- RUI architecture and components
- Definitions of RUIS (RUI Server) and RUIC (RUI Client) types and their roles.
- Detailed component and interaction diagrams for RUI Server, RUIC and abstract entities.
- Configuration models
- Internet model, 2‑tier model, and 3‑tier model for RUI deployment and retrieval.
- Operation scenarios
- Discovery and retrieval of server information, connection/handshake procedures, and controlling IGRS devices via RUI.
- RUI Description Language (RDL)
- RDL element set and schema (Annex A) including Package, LayoutContainer, SceneContainer, Item, Layout, Scene, Group, Asset, ItemRef, LayoutRef, Annotation, Descriptor, Condition, Choice, Selection, Statement, and DCCondition.
- Mechanisms for adaptive UI composition, navigation and conditional presentation.
- Conformance
- Clauses describing conformance requirements and normative references within the IGRS framework.
Applications and who uses it
This standard is targeted at stakeholders working on interoperable smart-home interfaces and remote control solutions:
- Device manufacturers building HES Class 2/3 devices that expose or host remote UIs.
- Smart-home platform providers and system integrators implementing IGRS-based resource sharing.
- Software developers and UI designers creating adaptive, cross-device interfaces (mobile apps, set-top boxes, in-vehicle displays).
- Standards engineers and test labs verifying conformance to IGRS RUI behavior.
Practical uses include remote control of lighting, HVAC, media and grouped device sets using adaptive UIs delivered over varied network topologies.
Related standards
- Other parts of ISO/IEC 14543 (HES architecture) that define device types, services and IGRS core mechanisms.
- Normative references cited in ISO/IEC 14543-5-11 for correct application and conformance testing.
