7、INFORMATION TECHNOLOGY TERMINOLOGY FOR THE HOME ELECTRONIC SYSTEM (HES) 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 partic
8、ipate 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
9、 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
10、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
11、 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
12、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 th
13、e 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 Int
14、ernational 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 Technical reports of type 3 do not necessarily have to be reviewed until the data they provide are considered to be no longer valid or useful.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 15044, which is a technical report of type 2, was prepared by subcommittee 25: Interconnection of information technology equipm
15、ent, of ISO/IEC joint technical committee 1: Information technology. International Standards are 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/I
16、EC JTC 1 (1998) as a prospective standard for provisional application in the field of the Home Electronic System (HES), because there is an urgent requirement for guidance on how standards in this field should be understood. This document is not to be regarded as an International Standard. It is pro
17、posed 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 the IEC Central Office. A review of this type 2 technical report will be carried out not later than three years after its publicatio
18、n with the option of extension for a further three years or conversion either to an International Standard or withdrawal.
