FOREWORD

1) 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.

2) The formal decisions or agreements of IEC and ISO 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 and ISO member bodies.

3) IEC, ISO and ISO/IEC publications have the form of recommendations for international use and are accepted

by IEC National Committees and ISO member bodies in that sense. While all reasonable efforts are made to

ensure that the technical content of IEC, ISO and ISO/IEC publications is accurate, IEC or ISO 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 and ISO member bodies undertake to

apply IEC, ISO and ISO/IEC publications transparently to the maximum extent possible in their national and

regional publications. Any divergence between any ISO, IEC or ISO/IEC publication and the corresponding

national or regional publication should be clearly indicated in the latter.

5) ISO and IEC do not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. ISO or IEC are not responsible

for any services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or ISO or its directors, employees, servants or agents including individual experts

and members of their technical committees and IEC National Committees or ISO member bodies 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 of, use of, or reliance upon, this ISO/IEC

publication or any other IEC, ISO or ISO/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 ISO/IEC publication may be the subject of

patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

International Standard ISO/IEC 14543-5-8 was prepared by subcommittee 25: Interconnection

of information technology equipment, of ISO/IEC joint technical committee 1: Information

technology.

The list of all currently available parts of the ISO/IEC 14543 series, under the general title

Information technology – Home electronic system (HES) architecture, can be found on the

message-exchange framework among devices.

• Specifies a series of device and service interaction/invocation standards, including

device and service discovery protocol, device and service description, service
invocation, security mechanisms, etc.

• Specifies core protocols for a type of home network that supports streaming media and

other high-speed data transports within a home.
– Parts 5-2#: Application profile

other

Note 1 to entry: Two users with buddy relationship are shown in each other’s roster.

3.1.3
connection ID

3.1.8
device verification code
string used to examine if the user has the authority to bind a device

Note 1 to entry: For a device without a user interface, the device verification code is used to bind a device to a

user. The device owner guarantees the safety of the device verification code.
3.1.9
