@foone oh heck yeah. I had a brief look at videocipher and figured there wasn't enough info out there to make a scrambler. I guess you found more than I did!
@philpem@sam@scarlet
With teletext, of course.. I've got a couple of SofTel inserters, plus a generator, that would slot right in.
Having seen so much posted about #emfcamp this year, I'm definitely going to have to work out how I can get to the next one! Might even be tempted to set up some sort of viewdata service, too..
@robert@philpem
I'm confident that by 2026 vbit2 will have databroadcast capability... Whether I've thought of a use for that by then is a different matter of course 😅
@robert@philpem thankfully it'll happily give me raw packet data so I can just implement my own version until such time as I can get a patch into libzvbi if that's even possible (someone does seem to have taken over maintenance recently so 🤞)
@zxguesser@robert If there's nothing left, I have been modifying Broadcast Projects Teletext receivers to give them more capabilities. I'm pretty sure the EURO-CCT chips can do datacast.
@philpem@robert we ought to be able to do something on a Beeb too. Though that might involve me learning some 6502 which I made no progress with last time I tried 😬
@zxguesser@philpem
Ah, I tried generating teletext on a Beeb, ~1989.. Moved the top of screen up, poked data into the right bits of video RAM. Just as we're doing now with the Pi. I didn't succeed, as I'm not sure I got it in the right place, and the only teletext TV was in another room, so a lot of walking back and forth made me give up fairly quickly, but it was a fun try..
