Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work. In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for
the different types of document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
Details of any patent rights identified during the development of the document will be in the Introduction
and/or on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT), see the following URL: Foreword — Supplementary information.
The committee responsible for this document is ISO/IEC JTC 1, Information technology, Subcommittee
SC 29, Coding of audio, picture, multimedia and hypermedia information.
ISO/IEC 23008 consists of the following parts, under the general title Information technology — High

Introduction
This part of ISO/IEC 23008 specifies technologies for the delivery of coded media data for multimedia
services over concatenation of heterogeneous packet-based network segments, including bidirectional IP
networks and unidirectional digital broadcasting networks. In this part of ISO/IEC 23008, “coded media
data” includes both timed audiovisual media data requiring synchronized decoding and presentation of
each specific unit of data at a designated time and non-timed data that could be decoded and presented
at an arbitrary time based on the context of the service or the user interaction.
MMT is designed under the assumption that the coded media data will be delivered through a packet-
based delivery network. Several characteristics of such delivery environments have been taken into
consideration, such as non-constant end-to-end delivery delay of each packet from the sending entity to
the receiving entity and means to distinguish signaling messages from the media data provided by the
underlying network.
For efficient and effective delivery of coded media data over heterogeneous packet-based delivery
networks, this part of ISO/IEC 23008 provides the following elements:
— logical model to construct content composed of components from various sources (e.g. content for
mash-up applications);
— structure of data conveying information about the coded media data for processing by the delivery
layer (e.g. packetization and adaptation);
— packetization method and the structure of the packet to deliver media content over packet-based
delivery networks supporting hybrid multichannel delivery that is agnostic to the specific type of
media or coding method;
— format of signaling messages to manage the presentation and delivery of media content;
— format of information to be exchanged across layers of the delivery network to facilitate cross layer
communication.
