Teletext capture?

[willow5]

Hi all, can someone kindly advise whether it is possible to capture the teletext information which is recorded as part of the signal from a cassette? SvHS can capture more of this information as shown in the picture which my TV decided today!

I would assume not, since this is in non-visual information. CC can be captured into MPEG via ATI MMC (but only without using a frame TBC), that I recall, but that's about it.

Teletext stored on a VHS tape has a lot of missing elements for a normal TV decoder to recover due to the crappy bandwidth of a VHS tape, You'll need a different approach using a software that can extract Teletext data from a video frame:

Here is a detailed explanation of the process:

Thanks all, I read on another forum this:

"With a Hauppauge WinTV card (and I believe all their analogue models, up to 1775), you can extract the teletext pages"

Is this true does anyone know?

You can extract teletext with any capture card, It is part of the scan lines and head switch, The question is would your TV be able to decode it? read my above post again.

You can only get the teletext signal from a Super-VHS recording, on a Super-VHS cassette,
you can replay the Teletext on your Teletext able tv, decoding Teletext from the capture of that Super-VHS recording is an other story......

Found the same thing the others found with a Google search...
But what also should be mentioned......you need the Linux OS for it... i don't think anything will be available for the Micro$oft OS...
