Decoding Teletext on PCTV card

I have a PCTV card in my computer and would like to write some Pascal
programs that read and process some information contained on Teletext
pages.

Does anyone have any info or experiences in doing this or who can
point me in the right direction.

Would probably help if we know if the screen is a windows or DOS
program. If the latter then reading the screen is a simple exercise.

Sorry for the delay in replying, I've just changed my ISP and your
reply wasnt on my old ISP's newsserver.#

The TV/Teletext card uses the Brooktree 848 chip, whilst the software
it uses runs under windows, I'm hoping that there is someway I can
talk to it under BP 7 for Dos, I would thing that its going to take
some machine code calls to accomplish what I'm trying to do.

This kind of thing is new to me, most of my BP code has been for
accounting systems.

Any info al all appreciated.
