Full title and description

St IEC 62766-5-1-2017 — Consumer terminal function for access to IPTV and open multimedia services — Part 5-1: Declarative application environment. This International Standard defines the Declarative Application Environment (DAE) component of the OIPF terminal function (OITF): a declarative language–based browser environment for presentation of TV user interfaces, with scripting support for interaction with server-side applications and for access to OITF APIs.

Abstract

IEC 62766-5-1:2017 specifies the architecture, programming model and runtime behaviour of the DAE used in consumer IPTV/connected TV terminals. It describes application structure (application tree and display model), security and permission models, APIs available to declarative applications, resource management (caching, lifecycle and memory considerations), gateway discovery/control and the relationship to the Web standards TV profile defined in IEC 62766-5-2. The document is intended to enable interoperable DAE implementations and portable service content for TV platforms.

Scope

Defines the Declarative Application Environment (DAE) component of the OIPF terminal function (OITF) used in consumer terminals for IPTV and open multimedia services. The scope covers the DAE architecture and components, application definition and lifecycle, presentation/display model, interaction and scripting APIs, security and permission handling, resource and memory management, caching behaviour, widget concepts and gateway discovery/control — together with normative references required for interoperable implementations. The DAE is specified in the context of the Web standards TV profile given in IEC 62766-5-2.

Key topics and requirements

• DAE architecture and high-level overview: component breakdown and how DAE fits into the OITF.
• Application model: application tree, display model, active application lists and widget concepts.
• Scripting and APIs: declarative documents plus scripting interfaces to interact with server-side applications and other OITF functions.
• Security and permissions: origin handling (including broadcast-delivered documents), privileged APIs and inheritance of permissions.
• Resource management: application lifecycle, caching rules, memory usage constraints and performance considerations.
• Gateway discovery and control: mechanisms for discovering and controlling gateway functionality within the OITF framework.
• Normative references: dependency on related standards and profiles (for example 3GPP and Web-based profiles referenced in the normative clauses).

Typical use and users

Typical users include connected-TV and set‑top‑box manufacturers, IPTV and OTT platform vendors, middleware and software developers (UI and application authors), test and certification laboratories, system integrators and standards/regulatory bodies assessing interoperability and compliance for TV/web-based services. Implementers use the standard to design DAE runtimes, ensure app portability and to define conformance tests.

Related standards

IEC 62766-5-1 is part of the IEC 62766 series (consumer terminal function for access to IPTV and open multimedia services). Closely related documents include IEC 62766-5-2 (Web standards TV profile) which defines the HTML/CSS/related profile used by DAE, and other parts of the 62766 series and referenced specifications (notably selected 3GPP and CEA/UPnP related documents listed in the normative references). Implementers should consult the full IEC 62766 series and the normative reference list for complete interoperability context.

FAQ

Q: What is this standard?

A: IEC 62766-5-1:2017 specifies the Declarative Application Environment (DAE) component for consumer terminal functions that provide access to IPTV and open multimedia services — essentially a TV-focused declarative/browser environment and its runtime behaviour.

Q: What does it cover?

A: It covers the DAE architecture, application and display models, scripting and privileged APIs, security/permission rules, resource and lifecycle management, caching, widgets and gateway discovery/control, all within the context of the Web standards TV profile.

Q: Who typically uses it?

A: Set-top box and TV manufacturers, middleware vendors, IPTV/OTT platform operators, application developers creating TV apps, test labs and conformity assessors.

Q: Is it current or superseded?

A: IEC 62766-5-1:2017 is a published International Standard (edition 1.0, published 26 July 2017). The IEC entry lists a stability date (planned maintenance window) and no public superseding edition is listed as of the publication metadata; users should check the IEC Catalogue or their national standards body for any amendments or newer editions.

Q: Is it part of a series?

A: Yes — it is part of the IEC 62766 series addressing consumer terminal functions for IPTV and open multimedia services. Part 5-2 (Web standards TV profile) is directly referenced as the web profile that the DAE uses; other parts of the series address different terminal function components.

Q: What are the key keywords?

A: DAE, declarative application, OITF, OIPF, IPTV, connected TV, HTML5 TV profile, widgets, security model, application lifecycle, APIs, resource management.
