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.

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) or the IEC

list of patent declarations received (see http:// patents .iec .ch).

Introduction

The MMT reference and conformance software is defined as part of the MPEG-H standard in this

document. This document outlines the MMT reference and conformance software and describes how it

is used for conformance testing. It also collects a list of MMT features that need to be verified as part of

conformance testing.

The attachment, available at https:// standards .iso .org/ iso -iec/ 23008/ -4/ ed -1/ en, contains the updated

reference software source code implementing the MPEG media transport: MMT.tar.gz.

constitutes requirements of this document. For dated references, only the edition cited applies. For

undated references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions

For the purposes of this document, the following terms and definitions given in ISO/IEC 23008-1 apply.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

— ISO Online browsing platform: available at http:// www .iso .org/ obp
4 General

The reference and conformance software operates according to Figure 1. It takes as input the MPUs,

generic files and signalling messages that are to be transmitted. The MMTP sender then generates the

MMTP flow as a multiplex of MMTP packets from the different sources and uses BSD sockets to send

them to a pre-configured destination IP address and port number using MMTP over UDP. The MMTP

receiver de-multiplexes the MMTP flow based on the packet_id and the mode and passes the packets

to the corresponding reconstruction module. The reconstruction module extracts the payload and

reconstructs the resource (i.e. the MPU, the generic file, or the signalling message).

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.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of the joint technical committee is to prepare International Standards. Draft International

Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as

an International Standard requires approval by at least 75 % of the national bodies casting a vote.

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.

ISO/IEC 23008-4 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,

Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information.

This second/third/... edition cancels and replaces the first/second/... edition (), [clause(s) / subclause(s) /

Introduction

This part of ISO/IEC 23008 specifies the reference software. The reference software of ISO/IEC 23009 serves

two main purposes:
⎯ Validation of the written specification of the several parts of ISO/IEC 23008;

⎯ Clarification of the written specification of the several parts of ISO/IEC 23008

1 Scope

This part of ISO/IEC 23008 specifies the reference software implementing the normative clauses of some

parts of ISO/IEC 23008.

That is, test vectors comprising MMTP sender and MMTP Receiver that conform or do not conform to the

normative clauses of the other parts of ISO/IEC 23008 and corresponding software modules.
