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.
Amendment 2 to ISO/IEC 23000-9:2008 was prepared by Joint Technical Committee ISO/IEC JTC 1,
Information technology, Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia
information.

AMENDMENT 2: Harmonization on MPEG-2 TS storage
Replace 6.5 with the following:
6.5 Storage and playback of transport stream
6.5.1 Introduction
A simple storage and playback method of MPEG-2 TS is defined by utilizing a subset of MPEG-2 TS
Reception Hint Track functionalities defined in the ISO-FF (more specifically, ISO/IEC 14496-
12:2008/Amd.1:2009, Information technology — Coding of audio-visual objects — Part 12: ISO base media
file format — AMENDMENT 1: General improvements including hint tracks, metadata support, and sample
groups. Thus, if otherwise mentioned in this standard, the restrictions in the ISO-FF shall apply.
6.5.2 File structure and track type definition
An MPEG-2 TS is stored sequentially (i.e., untouched) as a sample data. A sample can be the whole TS to be
stored or a segment of it. All the sample boundaries shall be aligned with the TS packet boundaries.
A handler type of ‘hint’ (hint track) is used for the stored MPEG-2 TS and the matching media information
header shall be ‘hmhd’ (hint media header). The maxPDUsize and avgPDUsize fields in the ‘hmhd’ of the
TS hint track shall take the value of 188 (the TS packet size).
MPEG-2 TS hint tracks can be used in two contexts; one is to guide streaming servers to easily generate a
transport stream from the stored MPEG-2 TS and the other is to guide players for local playback or preview of
stored (or recorded) MPEG-2 TS. Note that this standard defines the latter one only.
In this standard, an MPEG-2 TS is always stored as ‘already-prepared’ samples regardless of whether it is
from direct reception or from content providers. Thus the MPEG-2 TS hint track defined in this standard does
not refer to other media tracks for dynamic composition of MPEG-2 TS from
