I succeeded in recording and playing back closed captioned TV, using
a Hauppauge WinTV card and Linux "MythTV" package. It appears that
many pieces of hardware, have the necessary closed caption extraction
capability. The missing part is software.
One thing I was not able to do, was take the proprietary MythTV file
format, and preserve the closed caption into another format (i.e.
burn a DVD). I was able to record a TV program, and play it back
later, with closed caption titles visible.
I also tried looking at the Linux source code, but couldn't figure out
how or where the closed caption was happening. (I was hoping to figure
out whether the info was embedded in some fashion, whether there
was a standard involved and so on.)
My recommendation to you:
Concentrate on the software. Go to commercial packages such as GBpvr
or SageTV or BeyondTV, and ask their pre-sales or technical support
people, whether CC is supported, and what hardware devices they've tested
with and support in their software. Then you can purchase a working
hardware and software combination.
I'm not convinced this is a hardware shortcoming. I've looked at a few
device datasheets, and they have options for extracting VBI information.
So the hardware industry hasn't ignored the issue.
