Full title and description

Information technology — High efficiency coding and media delivery in heterogeneous environments — Part 1: MPEG media transport (MMT). This international standard specifies MPEG Media Transport (MMT) technologies including a single encapsulation format (MPU/mpuf), associated signalling messages and delivery protocol(s) for transport and delivery of multimedia data across heterogeneous packet‑switched and broadcast networks.

Abstract

ISO/IEC 23008-1:2023 defines MMT (MPEG Media Transport): an ISOBMFF‑based MPU format (mpuf) for encapsulating timed and non‑timed media, signalling message formats for managing delivery and consumption, and delivery payload/transport protocol elements that allow fragmentation, aggregation and codec‑independent delivery of media over both bidirectional (IP) and unidirectional (broadcast) packet‑switched networks. The standard provides mechanisms to enable advanced delivery features and cross‑layer optimisations for multimedia services.

Scope

The standard specifies the formats and procedures required to encapsulate multimedia content into Media Processing Units (MPUs), to signal media locations and delivery configuration, and to deliver payloads in a codec‑agnostic way suitable for heterogeneous networks (IP and broadcast). It addresses MPU file/stream structure (mpuf ISOBMFF branding), signalling message formats for media management, payload formats enabling fragmentation and aggregation, and an application‑layer transport protocol to support advanced delivery scenarios and error‑resilient operation.

Key topics and requirements

• MPU (Media Processing Unit) format based on ISOBMFF; mpuf branding for self‑contained media consumption.
• Signalling message formats for media location, delivery configuration and consumption control.
• Delivery payload formats that are independent of media codec types, allowing fragmentation and aggregation of media data.
• Application‑layer transport protocol and mechanisms to support delivery over packet‑switched and broadcast networks (IP and unidirectional broadcast).
• Error‑resilience and transport‑conversion features to enable robust delivery across heterogeneous networks (including support routes for forward error correction via later amendments/extensions).
• Interoperability guidelines for combining MMT with other MPEG systems and profiles.

Typical use and users

Implementers and users include broadcast system designers, OTT and streaming platform engineers, middleware and CDN developers, codec and player vendors, network engineers working on multicast/unicast convergence, conformance/test laboratories, and standards working groups. Organisations adopting MMT typically seek flexible, codec‑agnostic delivery for mixed IP and broadcast distribution scenarios.

Related standards

ISO/IEC 23008 is a multi‑part suite (MPEG‑H). Key related parts include: ISO/IEC 23008-2 (High Efficiency Video Coding / HEVC) and its editions/amendments; ISO/IEC 23008-3 (3D audio / MPEG‑H 3D audio) and other parts covering image file formats and related tools (for example later parts such as Part 12 — Image File Format). These parts together form the MPEG‑H family addressing efficient coding, transport, audio and image file formats.

FAQ

Q: What is this standard?

A: ISO/IEC 23008-1:2023 is Part 1 of the MPEG‑H suite that defines MPEG Media Transport (MMT) — an encapsulation, signalling and delivery framework for multimedia over heterogeneous packet‑switched and broadcast networks.

Q: What does it cover?

A: It covers the MPU (mpuf) file/stream format, signalling message formats to manage delivery and consumption, delivery payload formats that are codec‑independent, and an application‑layer transport protocol to support advanced delivery features, fragmentation/aggregation and network heterogeneity.

Q: Who typically uses it?

A: Broadcasters, streaming and OTT platform developers, CDN and middleware vendors, device and player implementers, network engineers working on convergence of IP and broadcast, and standards/test labs.

Q: Is it current or superseded?

A: The 2023 edition (3rd edition) is the current published edition (replacing the 2017 edition). There are subsequent amendments in development/published to extend features (for example an Amendment for adaptive FEC signalling was published in 2025). Check the ISO catalogue for the latest amendments.

Q: Is it part of a series?

A: Yes — ISO/IEC 23008 is a multipart family (MPEG‑H). Part 1 is MMT; other parts address HEVC (Part 2), 3D audio (Part 3), image file formats and additional related specifications.
