IEC 62766-5-2:2017

Overview

IEC 62766-5-2:2017 - Web standards TV profile defines a common, interoperable profile of web technologies (HTML5, CSS and selected Web APIs) specifically tailored for connected TV and IPTV consumer terminals. Rather than extending or modifying core web standards, it selects a stable subset and - where needed for the TV environment - adds clarifications or constraints so content and service providers can reliably target TV devices and manufacturers can implement consistent behavior.

Key topics and technical requirements

• HTML5 and CSS profile: Specifies which HTML elements, global attributes and CSS modules are required or recommended for TV deployments (see Annex A support tables).
• Scripting and APIs: Defines support expectations for ECMAScript, event models, DOM/CSSOM interaction and specific Web APIs useful on TV such as:
  • XMLHttpRequest, WebSocket (RFC 6455), Web Storage and Web Workers
  • Canvas 2D APIs and Media-related APIs (media fragment URIs, media events)
• Media and responsive behavior: References media queries, media fragments and other mechanisms to adapt content and media playback to TV screens and remote-control navigation.
• Device constraints and clarifications: Adds TV-specific guidance (layout, fonts, device adaptation, remote control keycodes) and minimum device requirements such as memory usage guidance and virtual keycode mappings.
• Interoperability emphasis: The profile is intentionally a conservative subset designed for stability so real-world interoperability between service/content providers and multiple TV manufacturers can be achieved.

Practical applications

• Develop cross-device connected TV applications and interactive TV UIs that work consistently across compliant set‑top boxes and smart TVs.
• Enable service providers and OTT platforms to deliver web-based TV apps (menus, EPGs, overlays) without per-manufacturer customization.
• Guide manufacturers and firmware engineers implementing browser engines and app runtimes optimized for TV hardware and remote‑control input.
• Provide a baseline for test labs and QA teams verifying conformance and interoperability of TV web clients.

Who should use this standard

• Consumer electronics manufacturers (smart TV / STB vendors)
• Application and content developers targeting TV/IPTV platforms
• System integrators, platform operators and test labs
• Standards and compliance teams evaluating web-capable TV devices
