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.
ISO and IEC draw attention to the possibility that the implementation of this document may involve the
use of (a) patent(s). ISO and IEC take no position concerning the evidence, validity or applicability of any
claimed patent rights in respect thereof. As of the date of publication of this document, ISO and IEC had
received notice of (a) patent(s) which may be required to implement this document. However,
implementers are cautioned that this may not represent the latest information, which may be obtained
from the patent database available at www.iso.org/patents and https://patents.iec.ch. ISO and IEC shall
not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the World
Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT)
see www.iso.org/iso/foreword.html. In the IEC, see /understanding-standards.
This document was prepared by ITU-T (as ITU-T H.222.0) and drafted in accordance with its editorial
rules, in collaboration with Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information.
This ninth edition cancels and replaces the eighth edition (ISO/IEC 13818-1:2022), which has been
technically revised. It also incorporates the Amendment ISO/IEC 13818-1:2022/Amd 1:2023 and the
Technical Corrigendum ISO/IEC 13818-1:2022/Cor 1:2023.
The main changes are as follows:
— updates references to ISO/IEC 14496-1 where clause numbering and field naming has changed;
— clarifies a reference to ISO/IEC 23008-3, where the field 3dAudioSceneInfoID is named differently;
— removes semantic definitions for fields that do not exist in the respective syntax table (Table 2-123);
— improves the semantic definition for HDR_WCG_idc equal to '0';
— corrects a mismatch in field size between syntax table and semantic definition of
SubstreamOffset[k][j][i];
— corrects a misleading semantic definition of the media_description_flag for the Media_service_kind
descriptor.
