Full title and description

St IEC 62766-2-1-2016 — Consumer terminal function for access to IPTV and open internet multimedia services - Part 2-1: Media formats. This part specifies audio/video and associated media formats (including 3D video delivery) used by IPTV services and voice/video telephony over fixed and mobile access networks, and defines the media formats used at the UNI reference point UNIT-17 of the Open IPTV Forum functional architecture.

Abstract

IEC 62766-2-1:2016 defines the set of media formats, codec usage rules and system-layer formats required for interoperable delivery of IPTV and open-internet multimedia services. The document covers audio/video media combinations, video codecs and usage, subtitle and teletext formats, audio codecs, graphics and still image formats, and provisions for 3D video; it targets delivery to fixed terminals.

Scope

This part specifies formats for audio/video content provided by IPTV services (fixed-line and mobile access) and for voice/video telephony services. It excludes broadcast channel inputs of hybrid devices except where explicitly stated. The document defines media formats for 3D video and is primarily targeted at fixed terminals; it establishes the formats used on the UNI reference point UNIT-17 of the Open IPTV Forum architecture.

Key topics and requirements

• Audio‑video media format combinations and a media‑formats stack covering content and system layers.
• Defined video codecs and usage guidelines (profile/level, container/streaming constraints).
• Subtitle and teletext formats and their integration with streaming and broadcast services.
• Audio codec specifications and interoperability requirements.
• Graphics and still-image formats for user interfaces and on-screen displays.
• Support for 3D video delivery modes (targeted at fixed terminals).
• Mapping of formats to the UNI reference point UNIT-17 (OIPF functional architecture) to ensure terminal‑to‑network interoperability.

Typical use and users

Used by manufacturers of consumer terminals (set‑top boxes, smart TVs), middleware and chipset vendors, IPTV and broadband service providers, content packagers, interoperablity and conformance test laboratories, and systems integrators to ensure consistent media format handling and interoperability across networks and devices.
