The present document specifies the method by which ITU-R System B Teletext (ITU-R Recommendation BT.653 [3]), also known as EBU Teletext (see EN 300 706 [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
