21、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
22、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
23、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 Organizati
24、on 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 comm
25、ittee 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 i
26、s 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
27、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 conf
28、ormity 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 a
29、ny 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 Normat
30、ive 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 respons
31、ible for identifying any or all such patent rights. International Standard IEC 62298-1 has been prepared by IEC technical committee 100: Audio, video and multimedia systems and equipment. This bilingual version (2013-07) corresponds to the monolingual English version, published in 2005-05. This stan
32、dard cancels and replaces IEC/PAS 62298 published in 2002. This first edition constitutes a technical revision. The text of this standard is based on the following documents: FDIS Report on voting 100/922/FDIS 100/960/RVD Full information on the voting for the approval of this standard can be found

36、television experience. It can be seen as the successor to Teletext. TeleWeb is not restricted to the TV environment and can be deployed equally effectively in areas like DAB, DRM, and home automation. This standard gives a general overview of the TeleWeb application. 6 62298-1 IEC:2005 TELEWEB APPLI
37、CATION Part 1: General description 1 Scope This part of IEC 62298 gives a general overview of the TeleWeb application that allows Web- style text and graphics to be broadcast to, and displayed by, suitable decoders. TeleWeb services can be broadcast in a number of different ways, for example, VBI, D
38、VB, DAB, etc., and to a variety of decoder types, for example, TVs, portable decoders, PCs, etc. These transmission protocols are described separately. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edi

46、l description of TeleWeb 4.1 Aims The aim of TeleWeb is to deliver World Wide Web-style content to the living room TV to give the viewer an enhanced television experience. A TeleWeb service broadcasts data files containing text and high-definition graphics to suitable decoders. The data transmitted
47、can be closely linked to events within the accompanying TV programmes, or can be more general in nature to emulate a traditional, but higher definition, Superteletext service. It is intended that TV-based decoders be implemented in a cost-effective manner without recourse to the technology normally
48、associated with personal computers. In part, this is achieved by limiting the number of different types of multimedia data that can be used within a service. By careful design of the user interface, decoder manufacturers will be able to offer easy-to-use equipment for accessing TeleWeb services with
49、out requiring the consumer to be computer-literate. In addition, they will be able to customize their products to differentiate them from those of their competitors. The encoding and transmission scheme is designed to be as efficient and robust as possible consistent with conveying potentially large data files via a unidirectional channel or bi- directional channel with a low or high data rate. For example, TeleWeb data can be broadcast v
