IEC 62298-1:2005 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, DVB, DAB, etc., and to a variety of decoder types, for example, TVs, portable decoders, PCs, etc. These transmission protocols are described separately. This bilingual version (2013-07) corresponds to the monolingual English version, published in 2005-10. It cancels and replaces IEC/PAS 62298 published in 2002.

Overview

IEC 62298-1:2005 - TeleWeb Application – Part 1: General Description defines the core concepts behind the TeleWeb application, an innovation that enables broadcasting of Web-style text and graphics to compatible decoders over various broadcast platforms. As a successor to Teletext, TeleWeb aims to enhance the television viewing experience by merging the interactivity and visual presentation associated with the World Wide Web with traditional and digital broadcasting environments.

TeleWeb allows transmission of content such as text, images, and simple web elements, making them accessible on TVs, set-top boxes, portable decoders, and even personal computers. The standard outlines both the structural framework and the foundational requirements necessary for the effective delivery and display of TeleWeb content, supporting multiple delivery technologies including VBI (Vertical Blanking Interval), DVB (Digital Video Broadcasting), and DAB (Digital Audio Broadcasting).

Key Topics

Service Delivery and Decoding: TeleWeb services are designed to be transmitted across a variety of broadcast platforms and received by diverse decoder types. These protocols and compatibility are discussed for optimal flexibility and scalability.

Profiles: Two main profiles are defined: the Superteletext profile (providing enhanced teletext capabilities using fixed layouts, multiple fonts and styles, bit-mapped images, and navigation options), and the Hyperteletext profile (which adds increased interactivity and support for advanced web technologies).

Display Model: TeleWeb introduces a multi-plane display architecture, separating content into layers such as video, background, text/graphics, and optional cursor layers, with prioritization for effective user interface rendering.

Control and Navigation: The user interaction is designed to be intuitive, employing color-coded and numbered keys to facilitate movement through TeleWeb pages, selection of links, and activation of service functions.

Content Management: Supports service menus, "home" pages, bookmarks, and history features. Content can be filtered based on themes, services, or available memory.

Compatibility and Efficiency: Focuses on cost-efficient implementation, enabling manufacturers to produce user-friendly decoders while minimizing processing complexity.

Applications

Enhanced Television Services: TeleWeb is primarily used to provide an enriched TV viewing experience by overlaying web-style content such as news, weather, sports, or program-related information directly on-screen.

Interactive Broadcasts: The Hyperteletext profile enables interactive features, such as viewer participation or live updates, leveraging return channels when available.

Broadcaster Flexibility: Allows broadcasters to reuse existing infrastructure (like Teletext transmission) while introducing high-definition graphics and richer navigation.

Multiple Platforms: The specification supports not only TVs but also portable decoding devices and PCs, facilitating content delivery beyond traditional TV viewing.

Internationalization: With multi-language support (East and West European Latin-1 languages), TeleWeb is suitable for global deployment.
