GSO IEC 62298-2:2015 无线网络应用 第(2)部分：连接方法

This part of IEC 62298 specifies the transmission layer of TeleWeb. TeleWeb services can be broadcast in a number of different ways, for example, VBI, DVB, DAB, etc., and to a variety of decoder types, for example, TVs, portable decoders, PCs, etc. This standard specifies the transmission layer for VBI and DVB broadcasts.

GSO IEC 62298-1:2015 无线网络应用 第1部分：概述

This part of IEC 62298 gives a general overview of the TeleWeb application that allows Webstyle 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, DVB, DAB, etc., and to a variety of decoder types, for example, TVs, portable decoders, PCs, etc. These transmission protocols are described separately.

Teleweb application - Part 1: General description

GSO IEC 62298-3:2015 无线网络应用 第(3)号：无线上标形式

This part of IEC 62298 specifies the TeleWeb Superteletext profile that allows Web-style text and graphics to be displayed on suitable decoders. A TeleWeb service comprises multimedia data files whose format and attributes are defined by this specification. This specification focuses on the presentation layer especially the implementation of TeleWeb HTML. It further defines graphical requirements like colours and fonts and the used content formats. For information regarding general information and the transport layer, refer to IEC 62298-1 and IEC 62298-2.

GSO IEC 62106:2015 频率范围 87.5 MHz 至 108.0 MHz 的 VHF/FM 声音广播无线电数据系统 (RDS) 规范

This International Standard describes the Radio Data System, RDS, intended for application to VHF/FM sound broadcasts in the range 87,5 MHz to 108,0 MHz which may carry either stereophonic (pilot-tone system) or monophonic programmes ( see clause 2 – Normative references ITU-R Recommendations BS 450-3 and BS 643-2). The main objectives of RDS are to enable improved functionality for FM receivers and to make them more user-friendly by using features such as Programme Identification, Programme Service name display and where applicable, automatic tuning for portable and car radios, in particular. The relevant basic tuning and switching information therefore has to be implemented by the type 0 group (see 6.1.5.1), and it is not optional unlike many of the other possible features in RDS.

GSO IEC 62297-2:2015 广播应用程序的触发消息 第2部分：传输方法

This part of IEC 62297 specifies how the trigger messages defined in IEC 62297-1 are transmitted. A trigger is defined as information sent from a service provider as part of a data broadcasting transmission that initiates an application in a receiver. Additional information in the trigger message allows filtering or prioritization techniques to be applied at the receiver. Examples of possible use include the forcing of the display of information to warn of severe weather conditions and advising of extreme content in the TV programme. In an interactive system, a message or icon might be displayed inviting on-line access to vote, to register an interest in an advertised product, or to browse programme-related content. This standard specifies how trigger messages are broadcast using teletext technology. Both Page Format-Clear and Independent Data Line methods are defined, using protocols defined in ETSI EN 300 708.
