FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62328-1 has been prepared by IEC technical committee 100:

INTRODUCTION
Broadcast data in a transport stream can contain multiple associated objects. When that data
is distributed on interchangeable storage media, for example, optical disks, the associated
objects should be synchronized. Open distribution of the media requires that the data be
adapted to a standardized volume and file structure, which should conform to the existing
basic volume and file structure.

bibliography that apply to this and the other three parts. It also specifies requirements, design
considerations and content architecture.

6.1 Overview of digital broadcasting
Conversion from analogue broadcasting to digital broadcasting based on ISO/IEC 13818
(MPEG-2) is in progress in many countries.
From the point of view of contents protection, recording of digital broadcasting contents
requires circumspection and caution. A discussion about broadcast services and how to store
them onto built-in storage media has begun. Another point of discussion is how other
receivers in a house can access contents recorded by one receiver. It is expected that
distribution of contents and metadata via communications networks, such as the Internet, will
include access control data.
This standard aims at the following recording formats.
• A format which does not need to be conscious of built-in and removable media on the
application level in order that removable media can be used as an extension of the built-in
storage which has limited capacity.
• A format which records a digital broadcasting programme to a removable medium by one
receiver and play the programme by another receiver while protecting a content and
keeping compatibility between receivers using secure UDF.
• A format which can record contents distributed via broadcasting networks or removable
media.
6.2 Main target contents
The primary target contents of this standard are contents the recording of which is permitted
by copy control information but the recording directory to be stored of which is not specified.
However, contents whose recording directory is specified can also be recorded
