I know that many NTSC LaserDisc contain CC closed caption, with the line 21. But are there LaserDiscs with "PAL" CC? Actually, the CC in PAL use the line 22 and it's not common, but you can find many VHS with that in the UK and in Germany (the name is MovieText on this country). I have a decoder and VHS with this kind of closed caption ( https://www.journaldulapin.com/2021/05/24/pal-line-22/, in french), but i have not found LaserDisc with that. A guy in a french forum about LaserDisc say that there is LaserDisc with that, but i have only found PAL LaserDisc with teletext, not PAL CC.

Per the above. Thanks for clarifying Edwin. I wasn't 100% sure and only went off of a disc I actually own. Aside, the Garden Birds disc is actually quite nice and well thought out. You not only get the Teletext pages, which are actually very useful and informative, but you also get two soundtracks to switch between. One audio track has the ambient audio and David Attenborough narration. The other audio track removes the narration and leaves the ambient audio in place. A great touch and pre-DVD era too! Trying not to derail, but I would very much like to reintroduce the Teletext pages with my VP50 Pro in the chain. Is there a way to do this? This is the disc by the way, if anyone is interested. It's great! British Garden Birds (1981) [BBCV 1005L]

Thank you wasn't aware about that I think cc is a more robust compared with Teletext, as recording good quality Teletext on VHS is not so easy, you need s‐VHS or laserdisc which have higher bandwidth. The laserdisc examples above have 4 languages each, also the Warner Classic have info page's with their laserdisc catalogue

I've recently added support for PAL CC to ld-decode's VBI decoder, so I'd be very interested in any real examples of CC on PAL discs... Here's an example of PAL CC on a VHS tape (The Matrix, S016985) - you can see VITC on line 21 of both fields, and CC on line 22 of the first: Attachment:

Any PAL disc with this Pioneer tuning fork intro technically has a little bit of CC, because it's been standards-converted from an NTSC source with CC. But (a) it's on the wrong line, (b) it's a bit mangled from blending with the line below it and (c) it doesn't encode any text anyway (both bytes of data are 0) - so it's not very exciting! Maybe there's a disc out there converted from an NTSC source that happened to end up with the CC on the right line, though...? Attachment:
