Robert HamptonI have written a Python script that takes my Mastodon feed and turns it into #teletext pages, and I consider this time well spent.
Dickon Hood@Hampo For bonus points, encode them as WST in an MPEG transport stream...
@dickon I have a Raspberry Pi set up to output a teletext signal and it will definitely be going on that at some point.
@Hampo On the right line of a PAL-encoded stream, or just bitmapped somehow?
@dickon I use VBIT by Peter Kwan, which modifies the composite video output of a Raspberry Pi to include teletext data on the VBI. https://github.com/peterkvt80/vbit2
GitHub - peterkvt80/vbit2: Teletext streaming. Generates a T42 teletext stream from teletext pages. This can be used with inserter hardware or a Raspberry Pi to generate a video signal that teletext TVs can decode and display. It can also be used with vbit-iv to generate in-vision teletext on a Linux PC or Raspberry Pi.

@Hampo Oh wow. I had no idea that existed.
@Hampo I've spent hours and hours -- for BBC R&D -- parsing DVB streams, so I happen to know that the teletext line actually has an official table encoding within DVB, which is why I made the (frankly tongue in cheek) comment.
Nice to see people doing this sort of thing.
@dickon There’s a whole community of teletext enthusiasts out there, creating art and even full teletext services. There is Teefax, viewable online at https://zxnet.co.uk/teletext/viewer/?c=1, and SPARK at https://tvark.org
