Multimedia home networks - Home network communication protocol over IP for multimedia household appliances

This International Standard specifies the requirements for the interface between the Home Network Lower Layer for a country's home network of standalone-type household appliances and the TCP/IP Layer for cases where it is intended to introduce a TCP/IP Layer to each of the nodes comprising such home network of standalone-type household appliances. The specified interface in the Home Network Lower Layer consists of 2 portions, the TCP/IP Interface and the lower medium-specific Interface. Figure 3 shows the composition of the Home Network Layer and the standardized portions. In Annex C, this standard specifies the requirements for the lower medium-specific Interface One of these layers shall be IEEE 802.15.1, short-distance radio standard additional layers can be added in the future).

La CEI 62457:2012 spécifie les exigences relatives à l'interface entre la couche inférieure d'un réseau résidentiel pour un réseau résidentiel local d'appareils domestiques de type autonome et la couche TCP/IP (Protocole de commande de transmission/Protocole Internet, en anglais "Transmission Control Protocol/Internet Protocol") lorsqu'on souhaite introduire une couche TCP/IP à chacun des n uds comprenant ce réseau résidentiel d'appareils domestiques de type autonome. L'interface spécifiée dans la couche inférieure du réseau résidentiel est constituée de 2 parties, l'interface TCP/IP et l'interface inférieure spécifique au support. La présente version bilingue (2012-10) correspond à la version anglaise monolingue publiée en 2007-09.

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 62457 has been prepared by technical area 9: Audio, video and
multimedia applications for end-user network, of IEC technical committee 100: Audio, video
and multimedia systems and equipment.
The text of this standard is based on the following documents:

INTRODUCTION
By enabling standalone-type household appliances (household appliances other than
audiovisual equipment, PCs and PC-related equipment) such as white appliances (e.g. air
conditioners, refrigerators), sensors, health, exercise and fitness equipment to connect to and
work in conjunction with audiovisual equipment, PCs and/or PC-related equipment, it
becomes possible to deliver multimedia application services, such as displaying a “washing
completed” message of a washing machine on a TV screen or operating an air conditioner via
a TV screen, that otherwise would not be possible (see Figure 1).
To achieve these services, a home network standard for networks of standalone-type
household appliances and network standards for audiovisual equipment, PCs and PC-related
equipment are needed. It is also necessary to establish a system that allows equipment
belonging to a network to exchange data with other equipment of different types of networks.
A commonly used approach to allow networks of different types to exchange data with each
other is to use Gateways.
Because data transferred within, into and out of networks of standalone-type household
appliances are control data, which are much smaller in volume than data similarly transferred
for networks of audiovisual equipment, PCs and PC-related equipment, and because
standalone-type household appliances have longer service lives than audiovisual equipment,
PCs and PC-related equipment, home network standards for networks of standalone-type
household appliances have been established separately from network standards for
audiovisual equipment, PCs and PC-related equipment, and many different protocol standards
1)
have been in use for a long time in different countries .
On the other hand, recent advances in device and software technology have made it possible
to implement TCP/IP (which has been adopted worldwide for audiovisual equipment, PCs and
PC-related equipment) in certain standalone-type household appliances, and so establishing
a home network standard for networks of standalone-type household appliances in the form of
a standard for layers above TCP/IP would allow data to be directly exchanged between
household appliances and audiovisual equipment, PCs and PC-related equipment via TCP/IP
(see Figure 2 example1, example2). In turn, this would allow the creation of multimedia
application services that enable household appliances to work in conjunction with audiovisual
equipment, PCs and PC-related equipment.
The advantages of applying this standard are:
• it can be applied to many types of Home Network standards.
• both Home Network nodes with TCP/IP Layer and without can coexist under the same
Home Network middleware.
• Household appliances can communicate with audiovisual equipment, PCs and PC-related
equipment, and vice versa, without requiring any gateway.
• Household appliances can handle text and audiovisual data.
• Audiovisual equipment, PCs and PC-related equipment can handle Household appliances
data.
• Household appliances can freely select a suitable lower-layer medium from various lower-
layer media below TCP/IP.
