DIGITAL RIGHTS PERMISSION CODE

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.

International Electrotechnical Commission (IEC) draws attention to the fact that it is claimed that compliance with
this document may involve the use of patent.
IEC takes no position concerning the evidence, validity and scope of these patent rights.
The holder of this patent right has assured IEC that it is willing to negotiate licences under reasonable and non-
discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the
holders of these patent rights are registered with IEC. Information may be obtained from:

INTRODUCTION
The common ID system is used to systematically identify every entity, device and content that
would be involved in the course of digitally distributing content. The permission code can
express various sets of permission information and permission conditions necessary for
content transmission in a remarkably short code form. The permission code is not defined
from a technical perspective, but rather on the basis of permission information that rights
holders actually employ in the field, even if the permission code is recognized for its technical
effectiveness with respect to digital distribution of content.

DIGITAL RIGHTS PERMISSION CODE

1 Scope
This International Standard defines the permission code, a set of permission related
information in short code form, primarily intended for home server systems. The permission
code is comprised of a common ID system (content ID, issuer ID, receiver ID, device ID, etc.)
and a narrowly-defined permission code.
The common ID system is used to systematically identify every entity, device and content that
would be involved in the course of digitally distributing content. The permission code can
express various sets of permission information and permission conditions necessary for
content transmission in a remarkably short code form. The permission code is not defined
from a technical perspective, but rather on the basis of permission information that rights
holders actually employ in the field. Even after, the permission code is recognized for its
technical effectiveness with respect to digital distribution of content.

4.1 General
This standard defines permission as “an act by a certain issuing entity to authorize use for
content to a certain receiving entity under a certain set of permission classifications, usage
conditions, data management conditions and data export conditions”.
In order to distribute permission information with its associated content, this standard
represents permission information through 5 digital expressions, including permission actor ID,
permission classification, usage condition, data management condition and data export
condition. Permission actor ID is comprised of 3 identifiers; a content ID assigned to the
subject content and an issuer ID and receiver ID respectively, assigned to each permission
issuer and receiver. Permission classification indicates the class (or type) of the permission.
Usage condition, data management condition and data export condition detail restrictions
placed in the content.
We hereby define the permission code framework and the permission code as a code and
framework that combine these 5 elements; permission actor ID, permission classification,
usage condition, data management condition and data export condition. The basic permission
code is configured using a “tag – size – data” structure. This structure makes it easy to extend
the permission code. This standard specifies these configuration requirements in detail.
Within the home server environment, permission codes are used to notify users of associated
permission information upon content use, to generate DRM licenses to protect content rights
and to report usage upon content use.
The diagram illustrates the permission code usage environment subject to this specification.
The permission management server is an actor that issues permission codes in response to
requests from entities issuing permissions. The license server is an actor that generates
licenses concerning the protection of content rights. The distribution server is an actor that
delivers content to the home server environment. Additionally, the home domain represents
the content usage environment that conforms to the home. The home server and client
devices are playback devices that belong to the home domain.
