Foreword
This version, previously as an ETS now an EN, contains changes of an entirely editorial nature as follows:
1) add the DVB logo to the front page of the deliverable;
2) change the title from: "Digital broadcasting systems for television, sound and data services; etc." to "Digital
Video Broadcast (DVB); etc.";
3) add in the foreword the DVB acknowledgement.
This European Standard (Telecommunications series) has been produced by the Joint Technical Committee (JTC) of the
European Broadcasting Union (EBU), Comité Européen de Normalisation ELECtrotechnique (CENELEC) and the
European Telecommunications Standards Institute (ETSI).
NOTE: The EBU/ETSI JTC was established in 1990 to co-ordinate the drafting of standards in the specific field
of broadcasting and related fields. Since 1995 the JTC became a tripartite body by including in the
Memorandum of Understanding also CENELEC, which is responsible for the standardization of radio and
television receivers. The EBU is a professional association of broadcasting organizations whose work
includes the co-ordination of its members' activities in the technical, legal, programme-making and
programme-exchange domains. The EBU has active members in about 60 countries in the European
broadcasting area; its headquarters is in Geneva *.

Digital Video Broadcasting (DVB) Project
Founded in September 1993, the DVB Project is a market-led consortium of public and private sector organizations in
the television industry. Its aim is to establish the framework for the introduction of MPEG-2 based digital television
services. Now comprising over 200 organizations from more than 25 countries around the world, DVB fosters market-
led systems, which meet the real needs, and economic circumstances, of the consumer electronics and the broadcast
industry.

1 Scope
The present document specifies the method by which ITU-R System B Teletext (ITU-R Recommendation 653 [3]),
also known as EBU Teletext (see EBU SPB 492 [4]), may be carried in DVB bitstreams. This transport mechanism is
intended to satisfy the following requirements:
- to support the transcoding of the Teletext data into the Vertical Blanking Interval (VBI) of analogue video.
The transcoded signal should be compatible with existing TV receivers with Teletext decoders;
- the maximum data rate for each Teletext service is equivalent to 16 lines per field so that the service is always
suitable for transcoding into the VBI;
- the transmission mechanism should be capable of transmitting subtitles with accurate timing with respect to the
video (i.e. to within or near frame accuracy).
A more general data transport mechanism for conveying new types of data services is outside the scope of the present
document, but the transport syntax specified here can also be adapted for other data.
