Information technology - Home Electronic System (HES) Architecture - Part 1: Introduction

Various electrically controlled devices are used in homes and similar environments for many different applications. Examples of such applications are: lighting, heating, food preparation, washing, energy management, water control, fire alarms, blinds control, different forms of security control and entertainment (audio and video). An overview of such applications is given in the Catalogue of Applications of the HES (see Informative reference). When several such devices are able to interwork via a common internal network (in this document called a home network), the resulting total system is called a home control system. When a home control system follows all the specifications in the ISO/IEC HES Standards, it is called a Home Electronic System (HES).

Part 1: Introduction
FOREWORD
1) ISO (International Organization for Standardization) and IEC (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.
2) In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1. 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.
3) Attention is drawn to the possibility that some of the elements of this Technical Report may be the subject of
patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
The main task of IEC and ISO technical committees is to prepare International Standards. In
exceptional circumstances, a technical committee may propose the publication of a technical
report of one of the following types:
• type 1, when the required support cannot be obtained for the publication of an
International Standard, despite repeated efforts;
• type 2, when the subject is still under technical development or where, for any other
reason, there is the future but not immediate possibility of an agreement on an
International Standard;
• type 3, when the technical committee has collected data of a different kind from that which
is normally published as an International Standard, for example ‘state of the art’.
Technical reports of types 1 and 2 are subject to review within three years of publication to
decide whether they can be transformed into International Standards. Technical reports of
type 3 do not necessarily have to be reviewed until the data they provide are considered to be
no longer valid or useful.
ISO/IEC 14543-1, which is a technical report of type 2, was prepared by subcommittee 25:
Interconnection of information technology equipment, of ISO/IEC joint technical committee 1:
Information technology.
This publication has been drafted in accordance with ISO/IEC directives, Part 3.
This document is issued in the type 2 technical report series of publications (according to
15.2.2 of the Procedures for the technical work of ISO/IEC JTC 1 (1998)) as a prospective
standard for provisional application in the field of Home Electronic Systems (HES), because
there is an urgent requirement for guidance on how standards in this field should be used to
meet an identified need.
This document is not to be regarded as an International Standard. It is proposed for
provisional application so that information and experience of its use in practice may be
gathered. Comments on the content of this document should be sent to IEC Central Office.

– 4 – TR 14543-1 © ISO/IEC:2000(E)

A review of this type 2 technical report will be carried out not later than three years after its
publication with the option of extension for a further three years or conversion either to an

International Standard or withdrawal.

INTRODUCTION
Various electrically controlled devices are used in homes and similar environments for many

different applications. Examples of such applications are: lighting, heating, food preparation,

washing, energy management, water control, fire alarms, blinds control, different forms of

security control and entertainment (audio and video). An overview of such applications is

given in the “Catalogue of Applications of the HES” (see Informative reference).

When several such devices are able to interwork via a common internal network (in this

document called a home network), the resulting total system is called a home control system.

When a home control system follows all the specifications in the ISO/IEC HES Standards, it is

called a Home Electronic System (HES).
Three different classes of HES are defined. Class 1 has transport capabilities for telecontrol
applications only. Class 2 includes Class 1, but also supports switched medium bandwidth
data channels. Class 3 includes Classes 1 and 2 and in addition supports high bandwidth
switched data channels.
A home network may be based on one or more different media (for example power line,
balanced cables, infrared or radio) and may also be connected to outside networks (for
example telephone, cable television, power and alarm networks).
An implementation of the Home Electronic System will typically be assembled by a consumer,
one application at a time, starting from single applications like lighting control, security control
or audio and video control, to develop eventually into an integrated multi-application system.
The cost of adding an application depends on whether rewiring of the house is needed or
whether existing cables and prefitted ducts can be used. Hence the HES standards and
supplementary technical reports will also give guidance to architects and builders as well as
to users on how to share such resources.
Lifetime and innovation cycles vary between one device and another and between devices
and networks. To make it possible to add and to change existing devices as well as to enlarge
and to upgrade the home network keeping the existing devices, several stable interfaces, the
Universal Interface (UI) and the Process Interfaces (PIs) are defined between the home
network and the devices. The PIs are meant for simple devices not requiring the full
implementation of the HES application protocol. By using these interfaces a manufacturer can
design a device both to meet his specific marketing objectives and to give the option to
integrate that special device into a multi-application Home Electronic System. This added
value allows the user to take advantage of synergy between different applications.
To allow manufacturers to implement cheaper devices/network combinations, an HES
conformance type B is defined. In this case a device connects directly to the medium without

showing the UI or a PI. These devices will, however, be medium dependent and do not have
the advantages of devices with full HES conformance (type A conformance where the devices
include the Universal Interface).
