TV PCI & USB cards ... Teletext question?
 
The message o.uk.invalid
from lid (Alan Pemberton) contains
these words:

The packets are the rows of text as displayed (5 housekeeping bytes plus
40 display bytes). The last two housekeeping bytes contain the magazine
number and row address (ie how far down the screen it should appear).
Only packet 0 (the top row) contains the page and sub-page number.

snip

Thanks for the explanation, Alan.

Do you happen to know whether the teletext on digital TV is similar?
I've never been able to discover how much formatting is done by the
broadcaster, and how much by the STB.
