FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this technical specification may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
The main task of IEC technical committees is to prepare International Standards. In
exceptional circumstances, a technical committee may propose the publication of a technical
specification when
• the required support cannot be obtained for the publication of an International Standard,
despite repeated efforts, or
• the subject is still under technical development or where, for any other reason, there is the
future but no immediate possibility of an agreement on an International Standard.
Technical specifications are subject to review within three years of publication to decide
whether they can be transformed into International Standards.
IEC 62318, which is a technical specification, has been prepared by IEC technical committee
100: Audio, video and multimedia systems and equipment
The text of this technical specification is based on the following documents:
Enquiry draft Report on voting
100/575A/DTS 100/679/RVC
Full information on the voting for the approval of this technical specification can be found in the
report on voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

The committee has decided that the contents of this publication will remain unchanged until
2006-03-31. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.
A bilingual edition may be issued at a later date.

INTRODUCTION
Broadcasters, network providers and consumer electronics companies have their own home
server models, that are different from each other. In order to start a discussion on
standardization of home server technology, a home server conceptual model should be
established. The model should include all the server logical elements and the functionality,
which is required and expected by broadcasters, network providers, consumer electronics
companies and users.

HOME SERVER CONCEPTUAL MODEL
1 Scope
This Technical Specification describes a home server conceptual model for multimedia home
server systems. A home server conceptual model is specified from the standardization point of
view to clarify the functionality and modularity of existing and future home servers.
The model provides key technology of home servers to be standardized. It should be noted that
the modelling is not intended for actual implementation of home servers. The modelling is
expected to be a reference for discussing and developing new works of home server
standardization, and to contribute to ease of operation and connectivity of home servers.
The model is dealt with as an instance of the equipment structure model defined in IEC 61998.
