? I thought the decent chips had their own teletext data slicer? I know
my PVR's tvp5150 is capable of Closed Caption and/or WST decoding, and
with the "VCR mode" option, it might attempt some retrieval from a video
recording.
Not, of course, that the onboard software or the closed-source
tvp5150.so driver [*] makes the slightest bit of use of this...
Best wishes,
Rick.
* - I really ought to disassemble it so I can hack together a
work-alike that also allows for contrast/bright/saturation/sharp to
be set - yet another think the cacky bog-standard driver doesn't do.
And don't get me started on the Debian SD interface driver, or the
DM320's USB driver that pretty much *only* understands a *single*
mass storage device (no keyboards, no hubs...). Hmmm...
