       | How does one "recover" teletext data, you may wonder.
       | 
       | Apparently, there is software for extracting teletext signal
       | recorded on VHS tapes with the help of a video capture hardware:

         | Teletext was a big deal in the UK, especially for people of a
         | certain age. The computer games "mag", "Digitiser" was quite

         | looking closely at the software, what they've done is pretty
         | remarkable. due to loss in recording, the author home spun some
         | pretty clever reconstruction techniques that start to look
         | vaguely ml'ish.
         | 
         | which is kind of the joke i guess. a lot of what people call ml
         | and ai has been used for noisy signal decoding for a long, long
         | time.

         | like mine where DVB-T is used with Teletext). I wonder what are
         | the options to recover teletext from today digital TV.

           | A standard dvb dongle with tsduck to extract specifically the
           | teletext pid should do the trick. You can also use tsduck and
           | hides modulator to inject your own teletext to your tv. Or
           | you could use it to inject a HbbTV web page and do whatever
           | you want. Like including a teletext JS emulator.
