Abstract

Teletext will be one of the first and most prominent multimedia services offered in digital television networks. Teletext is well known and has already been available for many years in analogue television in Europe and elsewhere as an additional service provided by television operators. Digital Broadcast technology allows to enhance this kind of service in quality and functionality.

Digital Television technology provides many advantages in comparison to the analogue distribution methods, such as possible reuse of content from Internet-based services, improved navigation, better layout capabilities and support of animated content. These capabilities give more freedom to the application designers. However, it is yet undecided which application format is best suited for Digital Television Networks. In order to develop a large market it is required to consider standardised formats to ensure interoperability between different service providers. Unfortunately, various industrial consortia such as DVB/MHP, ATSC/DASE and DigiTAG are working on different solutions. The formats have to be supported by the designers of the applications, the network operators and the end systems, and specific tools have to be developed to enable application production taking the advantages of the new technology into account. This paper discusses various aspects of the production of Teletext applications for Digital Television Broadcast. The authoring system presented here is based on a generic approach to describe the applications’ layout and behaviour utilising XML data representation, templates and server-side scripting. The system is independent of the final interchange format and can generate several different representations such as MHEG-5 and XHTML to meet the requirements of upcoming broadcast environments and to enable publication of applications in the Internet using the same content source. Navigation style-guides are covered and techniques to create applications and the associated content via server-side scripts are discussed.
