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: https://github.com/ali1234/vhs-teletext

What amazingly strange hobbies people have!

Teletext was a big deal in the UK, especially for people of a certain age. The computer games "mag", "Digitiser" was quite central to games culture in the 90s.

I'm grateful to them for saving it!

Haven't read the article yet, came here to search comments to see if anyone mentioned digitiser! Loved that mag. Mr biffo now writes a monthly bit in UK retro gamer.

His series of posts on the history of Digitiser is an excellent read:

I think that's not possible on DVB-T (yes, there are countries 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.

I believe DVB-T still supported "analogue" teletext, but DVBs-own-telext is known as MHEG https://en.wikipedia.org/wiki/MHEG-5

...and I've no idea :)

It is possible on DVB-T and DVB-S, and it's possible to extract the teletext service from the transport streams.

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.

For a few years now I have been trying to resist filling my room/house with old VHS tapes for this purpose. This missing piece of the puzzle is not making it any easier.

Hungary's public television channels still use teletext and it's also available online: https://www.teletext.hu/

Now fixed, thanks for the heads up!
