This second edition European Telecommunication Standard (ETS) specifies the method by which ITU-R System B Teletext [3]@ also known as EBU Teletext [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 this ETS@ but the transport syntax specified here can also be adapted for other data.
