IEC 62481-6-1:2017

Overview

IEC 62481-6-1:2017 is the DLNA (Digital Living Network Alliance) guideline that defines the HTML5 Remote User Interface (RUI‑H) for home networked device interoperability. The standard enables developers and device manufacturers to deliver web-based user interfaces that are “write once, play anywhere” across browsers and platforms. By specifying device models, networking architecture, discovery, transport and presentation rules, IEC 62481-6-1 helps repurpose single HTML5 codebases to provide native, consistent UIs on TVs, set‑top boxes, media players and other consumer devices.

Key topics and technical requirements

• RUI‑H scope and device model
  • Defines DLNA home networking architecture, device capabilities and system usages (notably 2‑box and 3‑box interaction models).
• Discovery and service listing
  • Rules for discovery of HTML5 Remote UI services and UIListing representations.
• Transport and protocols
  • Guidance on RUI‑H transport, service URIs and caching, plus interaction with AV transport and control.
• Media formats and AV metadata
  • Requirements for supported media types, MPEG streams and AV metadata mapping for synchronized UI and media playback.
• Presentation and control (HTML5 specifics)
  • Detailed guidance for HTML/DOM, CSS, image and font formats, JavaScript APIs, input events and accessibility-related presentation.
• Security and interoperability
  • Content protection guidelines, Cross Origin Resource Sharing (CORS) considerations, and protocolInfo extensions (DLNA‑HTML5‑1.0).
• Quality of Service (QoS) and synchronization
  • Recommendations for media transport QoS and synchronized media/web content presentation.
• Normative and informative annexes
  • Client capability detection, web content authoring guidelines, input event mapping, examples and an XSD schema for extended protocolInfo.

Practical applications and who uses this standard

IEC 62481-6-1 is targeted at professionals involved in the digital home ecosystem:

• CE manufacturers (smart TVs, set‑top boxes, Blu‑ray players) implementing HTML5 RUIs.
• Software and UI developers building device‑side and remote browser‑based user interfaces.
• Service providers and operators deploying interactive services that must interoperate with customer premises equipment.
• System integrators and test labs verifying DLNA compliance and cross‑device interoperability.
• Content authors creating web‑based overlays, subtitles, ads and synchronized media experiences for home devices.

Benefits include reduced development cost through single codebases, consistent cross‑device UX, and clearer integration between web UI and AV playback.
