Teletext Packet Analyser

A python script to decode and sort through teletext datastreams.


Install with pip3 install . or install in editable mode with pip3 install -e . to allow you to edit the source without needing to re-install.


teletext-decoder -i <inputfile> -o <outputfile> [-p <page number>] [-s]

inputfile should contain concatenated 42 byte teletext packets (2 byte MRAG followed by 40 bytes of data). A 43 byte WST dump from a capture card can be decoded using the -s flag. A decoded and annotated representation of the teletext datastream will be written to outputfile. An optional teletext page number will return only the packets belonging to the specified page.
