One of my favourite things is finding the recovered page in the archive when people share a photo of their TV showing their letter or whatever πŸ˜€

My two best teletext recoveries ever, followed by two shredded tapes.

Most of my tapes have come out fairly smashed up but this one is stunningly clean. Check out the subtitles!
The thrill is slightly damped by it being 2004. If only the old recordings with interesting content could come out like this πŸ˜†

Teletext Viewer Web based teletext emulator with different services on each channel. Includes Teefax, Ceefax, and Chunkytext.

I've dragged the VCR out for the first time in over a year and a half to get back to some teletext recovery.
The first recording of this evening's tape is easily the best results I've ever had 🀯 I've fed it straight into the test channel on my online viewer: zxnet.co.uk/teletext/vie...

Maybe they're carrying RS485 or something, and you use a BS1363 to XLR cable like those cursed IEC C13 adapters from the other week πŸ˜†

Thankfully the worst I've done is sawn through the end of my thumbnail, but rather embarrassingly I've done it twice for different reasons πŸ€¦β€β™‚οΈ

Also while they take smaller bites, hand tools are just as hungry for blood.

I generally avoid posting anything with lots of recovery errors because they have a habit of doing the rounds on the internet for ever after which make me wince when I see them, but sometimes I get too excited to wait πŸ˜„

The countdown, logo, and the various index pages are for display as regular teletext pages, but the schedules etc are data pages intended to be downloaded somehow and printed off.
Unfortunately the main daily and weekly schedules seem to be compressed or scrambled

Now we're cooking! This is the sort of recovery quality I wanted to see from these recordings πŸ˜€

More IDENT from a much longer recording. You can see how the timings shift up the page as the items are broadcast.
(excuse all the mangled content this is still with a very hacked together teletext recovery process)

Technically we knew we had it four years ago, I just gave up at the "saw some mangled packets in the terminal window" stage and never got around to the "post screenshots that make sense" bit πŸ˜…

The downside is it means there's yet another teletext service to archive and all the tape captures to re-check 🀣

Still needs some work, but that was only a 20 second sample. Hopefully we can find some more recordings where this signal escaped and have a proper poke around πŸ˜„

Feeling at a loose end now that #ChunkyFringe is done and all the TVs are packed way until the next event, so I went picking at an old scab, and figured out how to process a hidden internal channel 4 teletext service called IDENT from a file that's been lurking on my hard drive since 2021 πŸ‘€

Ah well, ChunkyText is online all year round so I can put things like that up any time πŸ™‚
It's just that I only pester people when there's an event coming up πŸ˜†
