Long name	High efficiency coding and media delivery in heterogeneous environments — Part 2
Status	Published
Date	2015
Committee	ISO/IEC JTC 1/SC 29/WG 11

ISO/IEC 23008-2 is a standards document addressing high efficiency coding and media delivery for high bit-rate audio-visual services. It defines technical constructs for coding, encapsulation, and carriage intended to interoperate with contemporary audio-visual systems and distribution infrastructures. The standard interacts with organizations, technologies, and media formats widely used across broadcasting, streaming, and archival institutions.

Overview

ISO/IEC 23008-2 sits within a suite of standards produced by International Organization for Standardization, International Electrotechnical Commission, ITU-R, European Broadcasting Union, and industry groups such as Moving Picture Experts Group and Society of Motion Picture and Television Engineers. It complements work from ISO/IEC 14496, ISO/IEC 11172, MPEG-2, MPEG-4, H.264, and HEVC initiatives. Implementations frequently reference specifications from Digital Video Broadcasting, Advanced Television Systems Committee, 3GPP, DVB Project and national standards bodies like British Standards Institute, Deutsches Institut für Normung, and American National Standards Institute.

Scope and Purpose

The scope of ISO/IEC 23008-2 covers container structures, signalling, and metadata constructs for delivering coded audio-visual content between production, distribution, and consumption points such as studios, broadcasters, and consumer devices. Stakeholders include broadcasters like BBC, NHK, and NAB, technology vendors such as Sony, Samsung Electronics, Panasonic Corporation, and content providers including Netflix, Amazon (company), and YouTube. The purpose is to enable interoperability among encoders, decoders, transport systems, playout servers, and media players used by institutions like Smithsonian Institution and Library of Congress for preservation and distribution.

Technical Specifications

Technical specifications describe file format box structures, timing models, sample entry definitions, synchronization mechanisms, and signalling elements used in packaging. The standard references timestamping conventions similar to those used by RealNetworks, Apple Inc., and Microsoft media frameworks, as well as container lineage from QuickTime (software), ISO base media file format, and MP4. It defines mechanisms to carry multiple essence streams, timed metadata, and captioning services comparable to SMPTE, EBU, and ATSC signaling methods. Requirements relate to transport over networks deployed by Cisco Systems, Juniper Networks, and interconnection models used in Internet Engineering Task Force work.

Profiles and Codecs

While codec specification remains under the purview of codec-focused standards bodies such as MPEG-H, Joint Collaborative Team on Video Coding, and Fraunhofer Society, ISO/IEC 23008-2 specifies profiles and constraints for carrying streams encoded with codecs originating from HEVC, AV1, Dolby Laboratories, and legacy codecs like MPEG-2 Part 2. Profiles align with playback and streaming needs of consumer device ecosystems produced by LG Electronics, Intel Corporation, AMD, and mobile platforms from Apple Inc. and Google. The document permits interoperability with subtitle and audio systems standardized by DVB Project, CEA-608, and Dolby Laboratories metadata schemes, facilitating delivery to platforms such as Roku, PlayStation, and Xbox (console).

Implementation and Compliance

Implementers include encoder and packager vendors, content delivery networks like Akamai Technologies and Cloudflare, broadcaster playout systems, and software players developed by VLC media player, FFmpeg, and proprietary stacks in Microsoft Windows and Android (operating system). Compliance testing often references conformance suites and test vectors produced by consortia such as MPEG, ETSI, and AV1 test groups, and uses validation tools from institutions like Fraunhofer Heinrich Hertz Institute and academic labs at MIT, Stanford University, and Tsinghua University. Regulatory and procurement contexts involve agencies such as Federal Communications Commission and procurement rules used by European Commission programs.

History and Development

Development traces through collaborative international efforts convened in ISO/IEC JTC 1, with working group contributions from experts affiliated with companies and institutions like NTT, NHK Science and Technology Research Laboratories, Samsung Research, and university research groups including ETH Zurich and University of California, Berkeley. Influences include prior media packaging standards such as ISO/IEC 14496-12 and codec evolutions from MPEG-4 to HEVC and beyond. Revision cycles and amendments reflect stakeholder feedback from broadcasters, content platforms, and hardware vendors, paralleling standardization patterns seen in JPEG, MPEG, and SMPTE publications.
